  • How do I create links in the cells of a PHP generated table?

    - by typoknig
    I have a table generated from some PHP code that lists a SMALL amount of important information for employees. I want to make it so each row, or at least one element in each row can be clicked on so the user will be redirected to ALL of the information (pulled from MySQL database) related to the employee who was clicked on. I am not sure how would be the best way to go about this, but I am open to suggestions. I would like to stick to PHP and/or JavaScript. Below is the code for my table: <table> <tr> <td id="content_heading" width="25px">ID</td> <td id="content_heading" width="150px">Last Name</td> <td id="content_heading" width="150px">First Name</td> <td id="content_heading" width="75px">SSN</td> </tr> <?php $user = 'user'; $pass = 'pass'; $server = 'localhost'; $link = mysql_connect($server, $user, $pass); if (!$link){ die('Could not connect to database!' . mysql_error()); } mysql_select_db('mydb', $link); $query = "SELECT * FROM employees"; $result = mysql_query($query); mysql_close($link); $num = mysql_num_rows($result); for ($i = 0; $i < $num; $i++){ $row = mysql_fetch_array($result); $class = (($i % 2) == 0) ? "table_odd_row" : "table_even_row"; echo "<tr class=".$class.">"; echo "<td>".$row[id]."</td>"; echo "<td>".$row[l_name]."</td>"; echo "<td>".$row[f_name]."</td>"; echo "<td>".$row[ssn]."</td>"; echo "</tr>"; } ?> </table>

  • Is it possible to use CSS to align these divs/spans in a table-like manner? (While still retaining continuity)

    - by Justin L.
    I have <div class='line'> <div class='chord_line'> <span class='chord_block'></span> <span class='chord_block'>E</span> <span class='chord_block'>B</span> <span class='chord_block'>C#m</span> <span class='chord_block'>A</span> </div> <div class='lyric_line'> <span class='lyric_block'></span> <span class='lyric_block'>Just a</span> <span class='lyric_block'>small-town girl</span> <span class='lyric_block'>living in a</span> <span class='lyric_block'>lonely world</span> </div> </div> (Excuse me for not being too familiar with proper css conventions for when to use div/spans) I want to be able to display them so that each chord_block span and lyric_block span is aligned vertically, as if they were left-aligned and on the same row of a table. For example: E B C#m A Just a small-town girl living in a lonely world (There will often be cases where an empty chord block is matched up to non-empty lyric block, and vice-versa.) I'm completely new to using CSS to align things, and have had no real understanding/experience of CSS aside from changing background colors and link styles. Is this possible in CSS? If not, how could the div/class nesting structure be revised to make this possible? I could change the spans to divs if necessary. Some things I cannot use: I can't change the structure to group things by a chord_and_lyric_block div (and have their width stretch to the length of the lyric, and stack them horizontally), because I couldn't really copy/select the lyrical lines continuously in their entirety, which is extremely critical. I'm trying to avoid a table-like solution, because this data is not tabular at all. The chord line and the lyric line are meant to be read as one continuous line, not a set of cells. Also, apart from the design philosophy reasons, I think it might have the same problems as the previous thing bullet point. If this is possible, what div/span attributes should I be using? Can you provide sample css? If this is not possible, can it be done with javascript? EDIT: I'm sorry I wasn't clear at the start, but I would like a solution that allows both the chord line and the lyric line to be "selectable" and continuous.

  • load search results into a div that toggles with other divs

    - by Z. Edwards
    I am working with a page that has multiple divs that toggle. This function works. A search function was added and this works too. The problem with the page as it exists currently: The search bar was placed on the "default" div and the results load below the bar into another div that is invisible when empty. The results div is inside this first default div. If you toggle to another div, you lose the default div and can't get back to it. For this reason, I moved the search bar to the left navigation where the other toggle links are situated. I also moved the search results div out of the default div to "stand on its own." What I am trying to do: Make the search button show the div with the results as well as find the results. Basically, to integrate the search function into the array/toggle function. The search function is in one .js file and the toggle function is in a different .js file. I keep thinking there must be a way to get "onclick" to call from both .js files so that I don't have to do a bunch of extra work combining the two functions that already exist and work separately. I am a Javascript newbie learning by examples and haven't been able to figure this out. I have never seen a working example of this and my searches haven't produced one. I would be very grateful for any help. Hope I explained the problem adequately. Edit: Here is the code I already have for the toggle function. var ids=new Array('a','b','c',[and so on--search results not added here yet]); function switchid(id_array){ hideallids(); for( var i=0, limit=id_array.length; i < limit; ++i) showdiv(id_array[i]); } function hideallids(){ for (var i=0;i<ids.length;i++){ hidediv(ids[i]); } } function hidediv(id) { //safe function to hide an element with a specified id if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById(id).style.display = 'none'; } else { if (document.layers) { // Netscape 4 document.id.display = 'none'; } else { // IE 4 document.all.id.style.display = 'none'; } } } function showdiv(id) {//safe function to show an element with a specified id if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById(id).style.display = 'block'; } else { if (document.layers) { // Netscape 4 document.id.display = 'block'; } else { // IE 4 document.all.id.style.display = 'block'; } } } function initialize(){ var t = gup("target"); if( t ) { switchid([t]); } } function gup( name ) { name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]"); var regexS = "[\\?&]"+name+"=([^&#]*)"; var regex = new RegExp( regexS ); var results = regex.exec( window.location.href ); if( results == null ){ return ""; } else { return results[1]; } } Thanks in advance!

  • Jquery accordion, next and previous wizard, how to get previous and next sections?

    - by Wbdvlpr
    Hi I have a Jquery accordion which works fine. Sections get expanded/collapsed when clicked on respective headers. But I want to add the functionality so that when I click on "next" button it opens up the next section and clicking "Previous" button takes me back to previous section. This has been done on this page http://jquery.bassistance.de/accordion/demo/?p=1.1.2 (last example) but not sure how do I implement the same in my case. Any suggestions please. Thanks UPDATE: How do I get previous or next section of the accordion? <script type="text/javascript"> $("#accordion").accordion({ header: "h3.header" , autoHeight: false , collapsible: true }); </script> <div id="accordion"> <h3 class="header">Section 1</h3> <div> content 1 .. content 1 .. content 1 .. content 1 .. <input class="next" type="button" value="next"/> </div> <h3 class="header">Section 2</h3> <div> content 2 .. content 2 .. content 2 .. content 2 .. <input class="previous" type="button" value="previous"/> <input class="next" type="button" value="next"/> </div> <h3 class="header">Section 3</h3> <div> content 3 .. content 3 .. content 3 .. content 3 .. <input class="previous" type="button" value="previous"/> </div> </div>

  • jquery position changing with .css() behaving strange

    - by 11684
    I tried to make a moving img, and it works partially. If I press the right, up or down button, it moves right, up or down. But, if I press the left button, it jumps very fast very far to the right, and then back to the left and doesn't stop moving (I believe. I said it was fast). JSFiddle; Javascript: $(document).ready(function() { var up = down = left = right = false; var top = 100, left = 500; $("body").on("keydown", function(e) { if(e.keyCode == 39) {e.preventDefault(); if (right == false) right = setInterval(moveRight, 80);} else if(e.keyCode == 37) {e.preventDefault(); if (left == false) left = setInterval(moveLeft, 80);} else if(e.keyCode == 38) {e.preventDefault(); if (up == false) up = setInterval(moveUp, 80);} else if(e.keyCode == 40) {e.preventDefault(); if (down == false) down = setInterval(moveDown, 80);} }); $("body").on("keyup", function(e) { if(e.keyCode == 39) {clearInterval(right); right = false;} else if(e.keyCode == 37) {clearInterval(left); left = false;} else if(e.keyCode == 38) {clearInterval(up); up = false;} else if(e.keyCode == 40) {clearInterval(down); down = false;} }); function moveUp() { top -= 2; $("#player").css("top", top + "px"); } function moveDown() { top += 2; $("#player").css("top", top + "px"); } function moveLeft() { left -= 2; $("#player").css("left", left + "px"); } function moveRight() { left += 2; $("#player").css("left", left + "px"); } }); This is probably not the best way to do this, I'm open for better suggestions. Thanks for reading!

  • jQuery bug when trying to insert partial elements before() / after() ?

    - by RedGlobe
    I'm trying to wrap a div around an element (my 'template' div) by using jQuery's before() and after(). When I try to insert a closing after the selected element, it actually gets placed before the target. Example: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <title>Div Wrap</title> <script src="http://code.jquery.com/jquery-1.4.4.min.js"></script> <script> $('document').ready(function() { var beforestr = "<div id=\"wrap\"><div id=\"header\">Top</div><div id=\"page\">"; var afterstr = "</div><div id=\"footer\">Bottom</div></div>"; $('#template').before(beforestr); $('#template').after(afterstr); }); </script> </head> <body> <div id="template"> <h1>Page Title</h1> <p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Mauris placerat eleifend leo. Quisque sit amet est et sapien ullamcorper pharetra. <script>document.write('This script should still work and might contain variables. Please don\'t recommend concatenation.');</script> Donec non enim in turpis pulvinar facilisis.</p> </div> </body> </html> The result is: <div id="wrap"> <div id="header">Top</div> <div id="page"> </div> </div> <div id="template"> <h1>Page Title</h1> <p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Mauris placerat eleifend leo. Quisque sit amet est et sapien ullamcorper pharetra. This script should still work and might contain variables. Please don't recommend concatenation. Donec non enim in turpis pulvinar facilisis.</p> </div> <div id="footer">Bottom</div> Why are my closing wrap and page divs getting placed before the target, when I'm trying to place them after() ? Is there an alternative way to accomplish this (keeping in mind I may need to call script functions within the template div)? As I'm sure you're aware, best practices aren't what I'm going for here.

  • Difficulty with jQuery and input keydown event

    - by Rosarch
    I am making a simple JavaScript enhanced list. I want it to be a list of inputs, each with an 'Add' and 'Remove' button. If the user clicks 'Add', a new li will be added. If the user clicks 'Remove', that li will be removed. It works fine, except for hitting "enter" in an <input>. Currently, it always causes the Remove.click event handler to fire, unless there's only one item in the list. I'm not sure why. How can I suppress this? Here is the complete jQuery. My attempt to fix the "enter" issue is commented out, and it doesn't work. I suspect that I could be designing this code better; if you see an improvement I'd love to hear it. function make_smart_list(list) { var ADD_CLASS = 'foo-widget-Add'; var REMOVE_CLASS = 'foo-widget-Remove'; var jq_list = $(list); jq_list.parents('form').submit(function() { return false; }); function refresh_handlers() { jq_list.find(sprintf('.%s, .%s', REMOVE_CLASS, ADD_CLASS)).unbind('click'); // jq_list.find('input').unbind('submit'); // // jq_list.find('input').submit(function() { // var jq_this = $(this); // var next_button = jq_this.nextAll('button'); // if (next_button.hasClass(ADD_CLASS)) { // next_button.nextAll('button').click(); // return; // } // // if (next_button.hasClass(REMOVE_CLASS)) { // return false; // } // // }); jq_list.find("." + REMOVE_CLASS).click(function() { var jq_this = $(this); jq_this.parent().remove(); refresh_handlers(); return false; }); jq_list.find("." + ADD_CLASS).click(function() { var jq_this = $(this); if (jq_this.prevAll('input').val() == '') { return; } jq_this.parent().clone().appendTo(jq_this.parent().parent()); jq_this.parent().next().find('input').val('').focus(); jq_this.removeClass(ADD_CLASS).addClass(REMOVE_CLASS); jq_this.text('Remove'); refresh_handlers(); return false; }); } refresh_handlers(); } (sprintf is another script I have.)

  • Jquery load() loading more than I want...

    - by Probocop
    Hi, I am trying to load just the contents of a <div> into another <div> on the same page using a jquery function. But when the function triggers, it loads the entire <HTML> document into the specified <div>. Any idea why it would be doing this? My code is as follows: Jquery: function button1() { $('#sidebar-content').fadeOut(function() { $(this).load('#button1').fadeIn(); }); } function button2() { $('#sidebar-content').fadeOut(function() { $(this).load('#button2').fadeIn(); }); } HTML: <div id="content-holder"> <div id="main-content" class="float-holder"> <div id="inner"> <h1>BRAND TRUTH</h1> <div id="flashcontent"> <div id="button1"> <div id="content"> <h1>Brand Truth</h1> <p>What this basically means is our way of working, the process involved by both ourselves and our client.</p> <p>When the truth wheel process is followed, the end result is so much stronger.</p> </div> </div> <div id="button2"> <div id="content"> <h1>Button 2 Content</h1> <p>Some other content</p> <p>Some other content x2</p> </div> </div> </div> <script type="text/javascript"> // <![CDATA[ var so = new SWFObject("working.swf", "working", "400", "400", "9", "#FFFFFF"); so.write("flashcontent"); // ]]> </script> </div> <div id="sidebar"> <div id="sidebar-content"> Replace Content Here! </div> </div> </div><!-- end #main-content --> </div><!-- end #content-holder -->

  • Advice on my jQuery Ajax Function

    - by NessDan
    So on my site, a user can post a comment on 2 things: a user's profile and an app. The code works fine in PHP but we decided to add Ajax to make it more stylish. The comment just fades into the page and works fine. I decided I wanted to make a function so that I wouldn't have to manage 2 (or more) blocks of codes in different files. Right now, the code is as follows for the two pages (not in a separate .js file, they're written inside the head tags for the pages.): // App page $("input#comment_submit").click(function() { var comment = $("#comment_box").val(); $.ajax({ type: "POST", url: "app.php?id=<?php echo $id; ?>", data: {comment: comment}, success: function() { $("input#comment_submit").attr("disabled", "disabled").val("Comment Submitted!"); $("textarea#comment_box").attr("disabled", "disabled") $("#comments").prepend("<div class=\"comment new\"></div>"); $(".new").prepend("<a href=\"profile.php?username=<?php echo $_SESSION['username']; ?>\" class=\"commentname\"><?php echo $_SESSION['username']; ?></a><p class=\"commentdate\"><?php echo date("M. d, Y", time()) ?> - <?php echo date("g:i A", time()); ?></p><p class=\"commentpost\">" + comment + "</p>").hide().fadeIn(1000); } }); return false; }); And next up, // Profile page $("input#comment_submit").click(function() { var comment = $("#comment_box").val(); $.ajax({ type: "POST", url: "profile.php?username=<?php echo $user; ?>", data: {comment: comment}, success: function() { $("input#comment_submit").attr("disabled", "disabled").val("Comment Submitted!"); $("textarea#comment_box").attr("disabled", "disabled") $("#comments").prepend("<div class=\"comment new\"></div>"); $(".new").prepend("<a href=\"profile.php?username=<?php echo $_SESSION['username']; ?>\" class=\"commentname\"><?php echo $_SESSION['username']; ?></a><p class=\"commentdate\"><?php echo date("M. d, Y", time()) ?> - <?php echo date("g:i A", time()); ?></p><p class=\"commentpost\">" + comment + "</p>").hide().fadeIn(1000); } }); return false; }); Now, on each page the box names will always be the same (comment_box and comment_submit) so what do you guys think of this function (Note, the postComment is in the head tag on the page.): // On the page, (profile.php) $(function() { $("input#comment_submit").click(function() { postComment("profile", "<?php echo $user ?>", "<?php echo $_SESSION['username']; ?>", "<?php echo date("M. d, Y", time()) ?>", "<?php echo date("g:i A", time()); ?>"); }); }); Which leads to this function (which is stored in a separate file called functions.js): function postComment(page, argvalue, username, date, time) { if (page == "app") { var arg = "id"; } if (page == "profile") { var arg = "username"; } var comment = $("#comment_box").val(); $.ajax({ type: "POST", url: page + ".php?" + arg + "=" + argvalue, data: {comment: comment}, success: function() { $("textarea#comment_box").attr("disabled", "disabled") $("input#comment_submit").attr("disabled", "disabled").val("Comment Submitted!"); $("#comments").prepend("<div class=\"comment new\"></div>"); $(".new").prepend("<a href=\"" + page + ".php?" + arg + "=" + username + "\" class=\"commentname\">" + username + "</a><p class=\"commentdate\">" + date + " - " + time + "</p><p class=\"commentpost\">" + nl2br(comment) + "</p>").hide().fadeIn(1000); } }); return false; } That's what I came up with! So, some problems: When I hit the button the page refreshes. What fixed this was taking the return false from the function and putting it into the button click. Any way to keep it in the function and have the same effect? But my real question is this: Can any coders out there that are familiar to jQuery tell me techniques, coding practices, or ways to write my code more efficiently/elegantly? I've done a lot of work in PHP but I know that echoing the date may not be the most efficient way to get the date and time. So any tips that can really help me streamline this function and also make me better with writing jQuery are very welcome!

  • Webkit browser jQuery transformations/transitions not working with jSplitSlider

    - by user3689793
    I am helping to build a site and i'm having an issue with the functionality of an add-in called jsplitslider when running it in chrome. Right now, when I navigate between the slides, the div's get stuck on top of each other and never clear the webkit transformations/animations: <div class="sl-content-slice" style="transition: all 800ms ease-in-out; -webkit-transition: all 800ms ease-in-out;"> I think the problem is due to timing of the functions, but I can't seem to figure out where I would need to add a setTimeout(). I only think this because I exhausted a lot of the other options like display: inline-block, notransitions css, etc. I'm desperate to figure out how to make this work in chrome. It works in FF and IE(surprisingly enough). I'm not great at webcoding, so any help will be appreciated! The code on the site isn't minimized. Here is the jQuery where I think the problem lies: var cssStyle = config.orientation === 'horizontal' ? { marginTop : -this.size.height / 2 } : { marginLeft : -this.size.width / 2 }, // default slide's slices style resetStyle = { 'transform' : 'translate(0%,0%) rotate(0deg) scale(1)', opacity : 1 }, // slice1 style slice1Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' } : { 'transform' : 'translateX(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' }, // slice2 style slice2Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' } : { 'transform' : 'translateX(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' }; if( this.options.optOpacity ) { slice1Style.opacity = 0; slice2Style.opacity = 0; } // we are adding the classes sl-trans-elems and sl-trans-back-elems to the slide that is either coming "next" // or going "prev" according to the direction. // the idea is to make it more interesting by giving some animations to the respective slide's elements //( dir === 'next' ) ? $nextSlide.addClass( 'sl-trans-elems' ) : $currentSlide.addClass( 'sl-trans-back-elems' ); $currentSlide.removeClass( 'sl-trans-elems' ); var transitionProp = { 'transition' : 'all ' + this.options.speed + 'ms ease-in-out' }; // add the 2 slices and animate them $movingSlide.css( 'z-index', this.slidesCount ) .find( 'div.sl-content-wrapper' ) .wrap( $( '<div class="sl-content-slice" />' ).css( transitionProp ) ) .parent() .cond( dir === 'prev', function() { var slice = this; this.css( slice1Style ); setTimeout( function() { slice.css( resetStyle ); }, 150 ); }, function() { var slice = this; setTimeout( function() { slice.css( slice1Style ); }, 150 ); } ) .clone() .appendTo( $movingSlide ) .cond( dir === 'prev', function() { var slice = this; this.css( slice2Style ); setTimeout( function() { $currentSlide.addClass( 'sl-trans-back-elems' ); if( self.support ) { slice.css( resetStyle ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); }, function() { var slice = this; setTimeout( function() { $nextSlide.addClass( 'sl-trans-elems' ); if( self.support ) { slice.css( slice2Style ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); } ) .find( 'div.sl-content-wrapper' ) .css( cssStyle ); $nextSlide.show(); }, _validateValues : function( config ) { // OK, so we are restricting the angles and scale values here. // This is to avoid the slices wrong sides to be shown. // you can adjust these values as you wish but make sure you also ajust the // paddings of the slides and also the options.translateFactor value and scale data attrs if( config.slice1angle > this.options.maxAngle || config.slice1angle < -this.options.maxAngle ) { config.slice1angle = this.options.maxAngle; } if( config.slice2angle > this.options.maxAngle || config.slice2angle < -this.options.maxAngle ) { config.slice2angle = this.options.maxAngle; } if( config.slice1scale > this.options.maxScale || config.slice1scale <= 0 ) { config.slice1scale = this.options.maxScale; } if( config.slice2scale > this.options.maxScale || config.slice2scale <= 0 ) { config.slice2scale = this.options.maxScale; } if( config.orientation !== 'vertical' && config.orientation !== 'horizontal' ) { config.orientation = 'horizontal' } }, _onEndNavigate : function( $slice, $oldSlide, dir ) { // reset previous slide's style after next slide is shown var $slide = $slice.parent(), removeClasses = 'sl-trans-elems sl-trans-back-elems'; // remove second slide's slice $slice.remove(); // unwrap.. $slide.css( 'z-index', 10 ) .find( 'div.sl-content-wrapper' ) .unwrap(); // hide previous current slide $oldSlide.hide().removeClass( removeClasses ); $slide.removeClass( removeClasses ); // now we can navigate again.. this.isAnimating = false; this.options.onAfterChange( $slide, this.current ); }, Sorry if I missed any conventions when posting, this is my first S.O. post.

  • Using JS script for "raining images". Can't seem to hide pre-loaded image

    - by user1813605
    I am trying to hide an image in a script pre-loading on the page. Below script makes images "rain" down the screen onClick. It functions well, but it displays the pre-loaded image itself on the page before the button is clicked. I'm trying to hide the image until the button is pressed.

  • touchend event doesn't work on Android

    - by Protos
    Hi, I've just started looking at doing some basic mobile web development on the android and an writing a test script to investigate the touch events. I've run the following code in the android emulator, and the touchend event never gets fired. Can anyone tell me why ? I've tried in three versions of the emulator (1.6, 2.1 and 2.2) and all three behave in the same way. Thanks in advance for any help you can give me.

  • Rails HABTM accepts_nested_attributes_for mapping table

    - by Rabbott
    Currently I have a habtm relationship between a datastream (stream), and a chart. I want to be able to use the 'typical' jquery "add new stream" method to add a new entry into a mapping table that holds the chart_id, and stream_id.. But I think that most examples out there are made to handle a one to many relationship.. The functionality provided here by Ryan Bates is what I'm looking for, But I dont want to use checkboxes, I want to use a select (drop down) to add new items to the mapping table. I need THIS and THIS combined chart.rb class Chart < ActiveRecord::Base has_and_belongs_to_many :streams, :readonly => false, :join_table => 'charts_streams' accepts_nested_attributes_for :streams, :reject_if => lambda { |a| a.values.all?(&:blank?) }, :allow_destroy => true stream.rb class Stream < ActiveRecord::Base has_and_belongs_to_many :charts, :readonly => false, :join_table => 'charts_streams' application.js /* * Method used to add new child form partials */ $('form a.add_child').click(function() { var assoc = $(this).attr('data-association'); var content = $('#' + assoc + '_fields_template').html(); var regexp = new RegExp('new_' + assoc, 'g'); var new_id = new Date().getTime(); var newElements = jQuery(content.replace(regexp, new_id)).hide(); $(this).parent().before(newElements).prev().slideFadeToggle(); return false; }); /* * Method used to remove child form partials */ $('form a.remove_child').live('click', function() { if(confirm('Are you sure?')) { var hidden_field = $(this).prev('input[type=hidden]')[0]; if(hidden_field) { hidden_field.value = '1'; } $(this).parents('.fields').slideFadeToggle(); } return false; }); _form.html.erb <div id="streams"> <h4>Streams</h4> <% form.fields_for :streams do |stream_form| %> <%= render :partial => "stream", :locals => {:f => stream_form} %> <% end %> </div> <p><%= add_child_link 'Add a stream', :streams %></p> <%= new_child_fields_template(form, :streams) %> _stream.html.erb <div class="fields"> <p> <%= f.label :stream_id %><br /> <%= select_tag "chart[stream_ids][]", options_for_select(@streams.map {|s| [s.label, s.id]}, f.object.id) %> </p> <p><%= remove_child_link 'Remove stream', f %></p> </div> This may be overkill and what I am looking to do could be much easier.. Basically when I create a chart I want to be able to add as many streams to it as I want, using the javascript for adding a new entry, and removing an old one... Thanks for the help! This is 'working' but gives me a ActiveRecord::ReadOnlyRecord error when it hits the chart.update_attributes method.. am I adding the the :readonly = false in the wrong spot? Or am I just doing it completely wrong?

  • Chaining CSS classes in IE6 - Trying to find a jQuery solution?

    - by Mike Baxter
    Right, perhaps I ask the impossible? I consider myself fairly new to Javscript and jQuery, but that being said, I have written some fairly complex code recently so I am definitely getting there... however I am now possed with a rather interesting issue at my current freelance contract. The previous web coder has taken a Grid-960 approach to the HTML and as a result has used chained classes to style many of the elements. The example below is typical of what can be found in the code: <div class='blocks four-col-1 orange highlight'>Some content</div> And in the css there will be different declarations for: (not actual css... but close enough) .blocks {margin-right:10px;} .orange {background-image:url(someimage.jpg);} .highlight {font-weight:bold;} .four-col-1 {width:300px;} and to make matters worse... this is in the CSS: .blocks.orange.highlight {background-colour:#dd00ff;} Anyone not familiar with this particular bug can read more on it here: http://www.ryanbrill.com/archives/multiple-classes-in-ie/ it is very real and very annoying. Without wanting to go into the merrits of not chaining classes (I told them this, but it is no longer feasible to change their approach... 100 hand coded pages into a 150 page website, no CMS... sigh) and without the luxury of being able to change the way these blocks are styled... can anyone advise me on the complexity and benefits between any of my below proposed approaches or possible other options that would adequately solve this problem. Potential Solution 1 Using conditional comments I am considering loading a jquery script only for IE6 that: Reads the class of all divs in a certain section of the page and pushes to an array creates empty boxes off screen with only one of the classes applied at a time Reads the applied CSS values for each box Re-applies these styles to the individual box, somehow bearing in mind the order in which they are called and overwriting conflicting instructions as required Potential Solution 2 read the class of all divs in a certain section of the page and push to an array Scan the document for links to style sheets Ajax grab the stylesheets and traverse looking for matching names to those in class array Apply styles as needed Potential Solution 3 Create an IE6 only stylesheet containing the exact style to be applied as a unique name (ie: class='blocks orange highlight' becomes class='blocks-orange-highlight') Traverse the document in IE6 and convert all spaces in class declarations to hyphens and reapply classes based on new style name Summary: Solution 1 allows the people at this company to apply any styles in the future and the script will adjust as needed. However it does not allow for the chained style to be added, only the individual style... it is also processor intensive and time consuming, but also the most likely to be converted into a plugin that could be used the world over Solution 2 is a potential nightmare to code. But again will allow for an endless number of updates without breaking Solution 3 will require someone at the companty to hardcode the new styles every time they make a change, and if they don't, IE6 will break. Ironically the site, whilst needing to conform to IE6 in a limited manner, does not need to run wihtout javascript (they've made the call... have JS or go away), so consider all jQuery and JS solutions to be 'game on'. Did I mention how much i hate IE6? Anyway... any thoughts or comments would be appreciated. I will continue to develop my own solution and if I discover one that can be turned into a jQuery plugin I will post it here in the comments. Regards, Mike.

  • Both tab & hover triggered popups problem

    - by carpenter
    I am trying to display divs when hovering over thumb-nails and/or both when tabbing onto them. If I stick to my mouse, the popups seem to work OK - if I start with a tab press I can show the popops also (foward only - no shift + tab yet). Any help getting them to play well together? <script type="text/javascript"> // Note: the below is being run from an onmouseover on a asp:HyperLink at the moment function onhovering_and_tabbingon2() { var active_hover = 0; var num_of_thumb; // set the default focus onto the first thumb-nail and make its popup display document.getElementById('link_no' + active_hover).focus(); // set focus on the first thumb $('#pop' + active_hover).toggleClass('popup'); // show its popup as it is hidden // for when hovering over the thumbs $(".box img").hover( // so as to effect only images/thumb-nails within divs of class=box when hovering over them function () { // test for if the image is a thumb-entry and not a popup image - of class=thumbs2 thumb = $(this).attr('class'); if (thumb != "thumbs2") { // I need to add/toggle the class here to a "div" and not to the image being hovered on, a div with text that corrosponds to the hovered on image though // so grab the number of the thumb_entry - to use to id the div. num_of_thumb = $(this).attr('id').replace('thumb_entry_No', ''); // find the div with id 'pop' + num_of_thumb, and toggleClass on it $('#pop' + num_of_thumb).toggleClass('popup'); // shows the hovered on pic's popup // move the focus to the hovered on pic's a tag ?????? document.getElementById('link_no' + num_of_thumb).focus(); // if the previous popup that was showing was in box2.. if (active_hover == 1 || active_hover% 2 == 1) { $('#pop' + active_hover).toggleClass('popup4_line2'); } else { // remove/toggle the previous active popup's visibility $('#pop' + active_hover).toggleClass('popup'); } // set the new active_hover to num_of_thumb active_hover = num_of_thumb; } }, function () { } ); // same thing again - but for my second row/line of entries/thumb-nails... $(".box2 img").hover( // so as to effect only images/thumbs within divs of class=box2 function () { // test if the image is a thumb-entry and not a popup image thumb = $(this).attr('class'); if (thumb != "thumbs2") { // I need to add the class here to a "div" and not to the image being hovered on, a div that corrosponds to the hovered on image though // so grab the number of the thumb_entry being hovered on, so as to id the div. num_of_thumb = $(this).attr('id').replace('thumb_entry_No', ''); // find the div with id='pop' + num_of_thumb, and toggleClass on it $('#pop' + num_of_thumb).toggleClass('popup4_line2'); // move the focus to the hovered on pic's a tag ?? document.getElementById('link_no' + num_of_thumb).focus(); // if the previous popup that was showing was in box.. // or if the active_hover is even (modulus) if (active_hover == 0 || active_hover % 2 == 0) { $('#pop' + active_hover).toggleClass('popup'); } else { // remove the previous active visible popup $('#pop' + active_hover).toggleClass('popup4_line2'); } // set the new active_hover to num_of_thumb active_hover = num_of_thumb; } }, function () { } ); // todo: I would like to try to show the popups when tabbing through the thumb-nails also // but am lost... document.onkeyup = keypress; // ???? function keypress() { // alert("The key pressed was: " + window.event.keyCode); if (window.event.keyCode == "9") { //alert("The tab key was pressed!"); active_hover = active_hover + 1; // for tabbing into box 2 (odd numbers) if (active_hover == 1 || active_hover % 2 == 1) { // toggle visibility of previous popup $('#pop' + (active_hover - 1)).toggleClass('popup'); // toggle visibility of current popup $('#pop' + active_hover).toggleClass('popup4_line2'); // } else { // for tabbing into box from box2 // toggle visibility of previous popup $('#pop' + (active_hover - 1)).toggleClass('popup4_line2'); // toggle visibility of current popup $('#pop' + active_hover).toggleClass('popup'); // } // ?????? // // if (window.event.keyCode == "shift&9") { } } } } </script>

  • dynamically drawing polylines on googlemaps using php/mysql

    - by arc
    Hi. I am new to the googlemaps API. I have written a small app for my mobile phone that periodically updates its location to an SQL databse. I would like to display this information on a googlemap in my browser. Ideally i'd like to then poll the database periodically and if any new co-ords have arrived, add them to the line. Best way of describing it is this; http://tiny.cc/HEIa0 In a quest to get to there, i've started on the documents on google and been modifying them to try and acheive what I want. It doesn't work - and i don't know enough to know why. I would love some advice as to why, and any pointers towards my ultimate goal would be very much welcomed. Google Maps AJAX + MySQL/PHP Example <script type="text/javascript"> //<![CDATA[ function load() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map")); map.addControl(new GSmallMapControl()); map.addControl(new GMapTypeControl()); map.setCenter(new GLatLng(47.614495, -122.341861), 13); GDownloadUrl("phpsqlajax_genxml.php", function(data) { var xml = GXml.parse(data); var line = []; var markers = xml.documentElement.getElementsByTagName("points"); for (var i = 0; i < points.length; i++) { var point = points.item(i); var lat = point.getAttribute("lat"); var lng = point.getAttribute("lng"); var latlng = new GLatLng(lat, lng); line.push(latlng); if (point.firstChild) { var station = point.firstChild.nodeValue; var marker = createMarker(latlng, station); map.addOverlay(marker); } } var polyline = new GPolyline(line, "#ff0000", 3, 1); map.addOverlay(polyline); }); } //]]> My php file is generating the following XML; <?xml version="1.0" encoding="UTF-8" ?> <points> <point lng="-122.340141" lat="47.608940"/> <point lng="-122.344391" lat="47.613590"/> <point lng="-122.356445" lat="47.624561"/> <point lng="-122.337654" lat="47.606365"/> <point lng="-122.345673" lat="47.612823"/> <point lng="-122.340363" lat="47.605961"/> <point lng="-122.345467" lat="47.613976"/> <point lng="-122.326584" lat="47.617214"/> <point lng="-122.342834" lat="47.610126"/> </points> I have successfully worked through this; http://code.google.com/apis/maps/articles/phpsqlajax.html before attempting to customise the code. Any pointers? Where am I go wrong?

  • Slow Jquery Animation

    - by Pyronaut
    I have this webpage : http://miloarc.pyrogenicmedia.com/ Which atm is nothing special. It has a few effects but none that break the bank. If you mouse over a tile, it should change it's opacity to give it a fade effect. This is done through the Jquery Animation, not through CSS (I do this so it can fade, instead of being a straight change). Everything looks nice when the page loads, and the fades look perfect. Infact if you drag your mouse all over the place, if gives you a "trail" almost like a snake. Anyway, My next problem is that you will see there is a box in the top left, which is going to tell you information about the tile you are hovering over. This seems to work fine. When you mouse over that information box, it switches it's position (So that you can reach the tiles that were previously hidden underneath it). From my understanding, this is all working fine, and to the letter. However, After one move of the info box (One hover). Viewing the page in Firefox turns slugish. As in, after a successful move of the info box, the fade effects become very stuttered, and it doesn't pick up events as fast meaning you can't draw a "trail" on the screen. Chrome doesn't have this issue. It seems to work fine no matter what. Safari also seems ok. Although I do notice if I move my mouse really fast, it does jump a bit but not as much as firefox. Internet explorer doesn't work at all. Seems to crash the browser... And there is an error with the rounded corner plugin im using (Not sure why...). All in all, I think whatever I'm doing inside my code must be heavily sluggish. But I don't know where it is happening. Here is the full code, but I would advise go to the link to view everything. <script type="text/javascript"> $(document).ready(function() { var WindowWidth = $(window).width(); var WindowMod = WindowWidth % 20; var WindowWidth = WindowWidth - WindowMod; var BoxDimension = WindowWidth / 20; var BoxDimensionFixed = BoxDimension - 12; var dimensions = BoxDimensionFixed + 'px'; $('.gamebutton').each(function(i) { $(this).css('width', dimensions); $(this).css('height', dimensions); }); var OuterDivHeight = BoxDimension * 10; var TopMargin = ($(window).height() - OuterDivHeight) / 2; var OuterDivWidth = BoxDimension * 20; var LeftMargin = ($(window).width() - OuterDivWidth) / 2; $('#gamePort').css('margin-top', TopMargin).css('margin-left', LeftMargin).css('margin-right', LeftMargin); $('.gamebutton img').each(function(i) { $(this).hover( function () { $(this).animate({'opacity': 0.65}); }, function () { $(this).animate({'opacity': 1}); } ); }); $('.rounded').corners(); $('.gamebutton').each(function(i) { $(this).hover(function() { $('.gameTitlePopup').html($(this).attr('title')); FadeActive(); }); }); function FadeActive() { $('.activeInfo').fadeIn('slow'); } $('#gameInfoLeft').hover(function() { $(this).removeClass('activeInfo'); $(this).fadeOut('slow', function() { $('#gameInfoRight').addClass('activeInfo'); FadeActive(); }); }); $('#gameInfoRight').hover(function() { $(this).removeClass('activeInfo'); $(this).fadeOut('slow', function() { $('#gameInfoLeft').addClass('activeInfo'); FadeActive(); }); }); }); </script> Thanks for any help :).

  • wave.getState() returns null

    - by RMorrisey
    When trying to call wave.getState() in my Google Wave gadget, I get back null (no state object). How can I initialize the Wave state object? I am working in the Wave Sandbox. My ModulePrefs contains the following: <Require feature="wave" /> <Require feature="rpc"/> I got the "rpc" feature from some google groups post when searching for a fix, but it doesn't seem to be any help. The gadget contains a jQuery plugin, which defines the classes I use (not shown), attaches an event handler to the link that shows up in edit mode, and sets up the callback methods with the google wave gadget initializer: $.fn.extend({ $.gork.InitPass.newButtonClick = function newButtonClick() { var jer = new $.gork.InitPass.Player('Jeremias', 12, 2); var delta = {}; delta[jer.name] = jer.serialize(); wave.getState().submitDelta(delta); }; $.gork.InitPass.modeCallback = function modeCallback() { var state = wave.getState(); var mode = wave.getMode(); $.gork.InitPass.getContainer().ipCombatState(state, (mode == wave.Mode.EDIT)); }; $.gork.InitPass.stateCallback = function stateCallback() { $.gork.InitPass.getContainer().ipCombatState( wave.getState(), (wave.getMode() == wave.Mode.EDIT)); alert('state'); }; $.gork.InitPass.init = function init() { if (wave && wave.isInWaveContainer()) { var mode = wave.getMode(); $('.gork-ip-container').ipCombatState(null, (mode == wave.Mode.EDIT)); wave.setModeCallback($.gork.InitPass.modeCallback); wave.setStateCallback($.gork.InitPass.stateCallback); } }; })(jQuery); gadgets.util.registerOnLoadHandler($.gork.InitPass.init); $(function ready() { $.gork.InitPass.getContainer().find('.gork-ip-edit .addSection a.newButton').click( $.gork.InitPass.newButtonClick); }); So there are two main pieces of functionality here: When the mode changes, ipCombatState(...) is called. This changes the visual appearance of the gadget when the user puts the gadget in Edit mode (CTRL+E), by hiding the view DIV and displaying the edit DIV. The newButtonClick callback (which is attached to the link "a.newButton" in the edit container) is supposed to add Jeremias (Nate's Shadowrun character) to the gadget state, so that he'll be appear as a table row in edit mode. I have verified that the initializer method is called, and the view/edit mode switch works just fine (except the state is null). When I click on the new button link (the link at the bottom in edit mode), and trigger the newButtonClick handler, I get an error because wave.getState() also returns null. How can I initialize the wave state so that I can work with it? The purpose of my gadget will be to keep track of combat initiative order in a Shadowrun tabletop game (4th Ed). You can test it out in Wave and see what I have so far: http://gorkwobble.herobo.com/wave/init-pass.xml The actual javascript code is externalized to: http://gorkwobble.herobo.com/wave/init-pass.js P.S. If any Shadowrun players read this, and want to hear about it when I get the gadget working, leave a comment and I'll wave you.
