  • jQuery doesn't work in IE8?

    - by Wade D Ouellet
    Hi, I am working on a site here: mfm.treethink.net All the jquery works fine in Firefox, Chrome and Safari but on IE8 it gives me errors and the banner at the top doesn't work (which uses the crossSlide jQuery plugin) and as well the image rollovers don't work with the colour change. IE8 is telling me that the errors are on lines 53, 134 and 149 in the source, all of those lines are where the jquery function is declared. $(document).ready(function(){ I am running jquery 1.4. Oddly enough, the other piece of jQuery I have on that page works, the artist browse/select menu on the right. But the banner and image rollovers don't. Here are all the scripts I'm running: 1: the banner - doesn't work in IE8 <script type="text/javascript"> $(function() { $('#banner').crossSlide({ sleep: 5, fade: 1 }, [ <?php $pages = get_posts('numberposts=2000&post_type=artist&post_status=publish'); $i = 1; foreach( $pages as $page ) { $content = $page->post_title; if( empty($content) ) continue; $content = apply_filters('the_content', $content); ?> { src: '/wp-content/uploads/<?php echo $page->post_name ?>.jpg' }, <?php $i++; } ?> ]); }); </script> 2 - image rollovers - doesn't work in IE8 <script type="text/javascript"> $(function(){ $("ul#artists li").hover(function() { /* On hover */ var thumbOver = $(this).find("img").attr("src"); /* Find image source */ /* Swap background */ $(this).find("a.thumb").css({'background' : 'url(' + thumbOver + ') center bottom no-repeat'}); $(this).find("span").stop().fadeTo('fast', 0 , function() { $(this).hide() }); } , function() { $(this).find("span").stop().fadeTo('fast', 1).show(); }); }); </script> 3 - the artist select - works in IE 8 <script> $("#browse-select").change(function() { window.location.href = $(this).val(); }); </script> These scripts were done by referencing previously made scripts, like I said I'm still new to jQuery. The second works in IE8 and the first one is the one that doesn't. I noticed the third one, the only one working, is written differently than the first two non-working ones without a function declaration at the top. Could this have anything to do with it? Any help figuring out this problem would be so appreciated. Thanks a lot, Wade

  • CSS * {margin: 0;padding: 0;} override

    - by StealthRT
    Hey all, i am in need of some help with figuring out how to override the "* {margin: 0;padding: 0;}" in my css. The reason why is that i have this css: .postcomments { width: 547px; padding: 5px 5px 5px 5px; margin: 0 0 5px 0;} .postcomments a { text-decoration: underline;} .postcomments ul { margin: 0; padding: 0; list-style-type: none;} .postcomments ul li { width: 547px; margin: 0 0 5px 0; padding: 0; list-style-type: none;} .postcomments .right { color: #474747; font-size: 11px; background: #fff url('http://www.nextbowluser.com/img/ucBG.gif') no-repeat top left; line-height: 17px; padding: 5px 0 0 0; width: 430px; position: relative; float: right; min-height: 50px;} .postcomments .right .bottom { padding: 0 5px 15px 5px; background: #fff url('http://www.nextbowluser.com/img/ucBG.gif') no-repeat bottom right; min-height: 50px;} .postcomments .arrow { left: -15px; top: 20px; position: absolute;} .avatar { border: none !important;} .postcomments .left {float: left; margin: 0 7px 0 0;} .postcomments .gravatar { background: #fff; width: 80px; height: 60px; margin: 0 0px 0 0; padding: 3px;} .postcomments .name { font-size: 11px; margin: 2px 0 0 0; color: #000;} .avatar { border: none !important;} and it displays just fine WITHOUT the * {margin: 0;padding: 0;}: 1st comment 2nd comment 3rd comment However, when i add that to the CSS, it makes the comments stack wrong: 1st comment 2nd comment 3rd comment I would just take out the * {margin: 0;padding: 0;} but some other things on the page needs that in order for that to be displayed correctly. So my question is, how can i override the {margin: 0;padding: 0;} for just that postcomments part of the page? Thanks! :o) David

  • getDate with Jquery Datepicker

    - by matt
    i am trying to get date from my implementation of jquery date picker, add it to a string and display the resulting image in my div. Something however is just not working. Can anyone check out the code and have a look at it? The code is supposed to take the date from date picker, combine it in a string which is to have the necessary code to display tag, images are located in /image and in the format aYY-MM-DD.png, new to this date picker and can't quite get it down yet. <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <link type="text/css" href="css/ui-lightness/jquery-ui-1.8.custom.css" rel="stylesheet" /> <script type="text/javascript" src="js/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="js/jquery-ui-1.8.custom.min.js"></script> <script type="text/javascript"> $(function(){ // Datepicker $('#datepicker').datepicker({ dateFormat: 'yy-mm-dd', inline: true, minDate: new Date(2010, 1 - 1, 1), maxDate:new Date(2010, 12 - 1, 31), altField: '#datepicker_value', }); //hover states on the static widgets $('#dialog_link, ul#icons li').hover( function() { $(this).addClass('ui-state-hover'); }, function() { $(this).removeClass('ui-state-hover'); } ); }); //var img_date = .datepicker('getDate'); var day1 = $("#datepicker").datepicker('getDate').getDate(); var month1 = $("#datepicker").datepicker('getDate').getMonth() + 1; var year1 = $("#datepicker").datepicker('getDate').getFullYear(); var fullDate = year1 + "-" + month1 + "-" + day1; var str_output = "<h1><center><img src=\"/images/a" + fullDate + ".png\"></center></h1><br/><br>"; page_output.innerHTML = str_output; // writing the results to the div element (page_out) </script> </head> <body style="background-color:#000;color:#fff;margin: auto auto;"> <!-- Datepicker --> <div id="datepicker"></div> <!-- Highlight / Error --> <p>Date Value: <input type="text" id="datepicker_value" /></p> <div id="page_output" style="text-align:center; margin-top:80px; margin-bottom:20px; "></div> </body>

  • What IDE to use for Python

  • Dojo extending dojo.dnd.Source, move not happening. Ideas?

    - by Soulhuntre
    Hey all, Ok... I have a simple dojo page with the bare essentials. Three UL's with some LI's in them. The idea si to allow drag-n-drop among them but if any UL goes empty due to the last item being dragged out, I will put up a message to the user to gie them some instructions. In order to do that, I wanted to extend the dojo.dnd.Source dijit and add some intelligence. It seemed easy enough. To keep things simple (I am loading Dojo from a CDN) I am simply declating my extension as opposed to doing full on module load. The declaration function is here... function declare_mockupSmartDndUl(){ dojo.require("dojo.dnd.Source"); dojo.provide("mockup.SmartDndUl"); dojo.declare("mockup.SmartDndUl", dojo.dnd.Source, { markupFactory: function(params, node){ //params._skipStartup = true; return new mockup.SmartDndUl(node, params); }, onDndDrop: function(source, nodes, copy){ console.debug('onDndDrop!'); if(this == source){ // reordering items console.debug('moving items from us'); // DO SOMETHING HERE }else{ // moving items to us console.debug('moving items to us'); // DO SOMETHING HERE } console.debug('this = ' + this ); console.debug('source = ' + source ); console.debug('nodes = ' + nodes); console.debug('copy = ' + copy); return dojo.dnd.Source.prototype.onDndDrop.call(this, source, nodes, copy); } }); } I have a init function to use this to decorate the lists... dojo.addOnLoad(function(){ declare_mockupSmartDndUl(); if(dojo.byId('list1')){ //new mockup.SmartDndUl(dojo.byId('list1')); new dojo.dnd.Source(dojo.byId('list1')); } if(dojo.byId('list2')){ new mockup.SmartDndUl(dojo.byId('list2')); //new dojo.dnd.Source(dojo.byId('list2')); } if(dojo.byId('list3')){ new mockup.SmartDndUl(dojo.byId('list3')); //new dojo.dnd.Source(dojo.byId('list3')); } }); It is fine as far as it goes, you will notice I left "list1" as a standard dojo dnd source for testing. The problem is this - list1 will happily accept items from lists 2 & 3 who will move or copy as apprriate. However lists 2 & 3 refuce to accept items from list1. It is as if the DND operation is being cancelled, but the debugger does show the dojo.dnd.Source.prototype.onDndDrop.call happening, and the paramaters do look ok to me. Now, the documentation here is really weak, so the example I took some of this from may be way out of date (I am using 1.4). Can anyone fill me in on what might be the issue with my extension dijit? Thanks!

  • Conflict between Jquery Validate and Asp.net MVC

    - by chobo2
    Hi I am using asp.net mvc 2.0 and jquery validate 1.7 (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) What happens is this. A user can click on a link to edit a product. When a user clicks on which product they want to edit a jquery dialog box appears with a form of textboxes and dropdown lists. These html controls have information filled in them. Say if the user chooses to edit the Ipad product a dialog will appear and one of the form textboxes will have "Ipad" in it. Now this form gets rendered on the server side(the form is in a partial view). When loading the dialog box a ajax request is made to get that partial view and in the response part of the ajax call I do something like $('#EditDialog).html(ajaxresponse).dialog({...}); So I would have something like this rendered in my dialog box <form id="EditProduct"> Product Name: <input type="text" value="IPad" name="ProductName" /> </form> Now my jquery validate would be something like this. $("#EditProduct").validate( { errorContainer: "#Errorbox", errorLabelContainer: "#Errorbox ul", wrapper: "li", rules: { ProductName: "required" } }); So I know this works because I use the same validate for add product and if you try to leave ProductName blank it will show a validation error. Now it does not work with the edit one though and I think I know the reason why but not how to fix it. The value for the textbox is "IPad" this is how the Html.TextBoxFor() renders it. However if a user goes and changes the product name to "Iphone" or blank the value never changes. It is always "Ipad" in the html. So I think when the validate goes and looks it goes oh there is a value already in it. It is valid even though in reality it might be blank. When I post to the server through ajax it gets the right value and the server side validation stops it but my entire clientside validation is rendered useless because of this problem as it will never change the html.

  • jQuery CSS plugin that returns computed style of element to pseudo clone that element?

    - by Keith Bentrup
    I'm looking for a way using jQuery to return an object of computed styles for the 1st matched element. I could then pass this object to another call of jQuery's css method. For example, with width, I can do the following to make the 2 divs have the same width: $('#div2').width($('#div1').width()); It would be nice if I could make a text input look like an existing span: $('#input1').css($('#span1').css()); where .css() with no argument returns an object that can be passed to .css(obj). (I can't find a jQuery plugin for this, but it seems like it should exist. If it doesn't exist, I'll turn mine below into a plugin and post it with all the properties that I use.) Basically, I want to pseudo clone certain elements but use a different tag. For example, I have an li element that I want to hide and put an input element over it that looks the same. When the user types, it looks like they are editing the element inline. I'm also open to other approaches for this pseudo cloning problem for editing. Any suggestions? Here's what I currently have. The only problem is just getting all the possible styles. This could be a ridiculously long list. jQuery.fn.css2 = jQuery.fn.css; jQuery.fn.css = function() { if (arguments.length) return jQuery.fn.css2.apply(this, arguments); var attr = ['font-family','font-size','font-weight','font-style','color', 'text-transform','text-decoration','letter-spacing','word-spacing', 'line-height','text-align','vertical-align','direction','background-color', 'background-image','background-repeat','background-position', 'background-attachment','opacity','width','height','top','right','bottom', 'left','margin-top','margin-right','margin-bottom','margin-left', 'padding-top','padding-right','padding-bottom','padding-left', 'border-top-width','border-right-width','border-bottom-width', 'border-left-width','border-top-color','border-right-color', 'border-bottom-color','border-left-color','border-top-style', 'border-right-style','border-bottom-style','border-left-style','position', 'display','visibility','z-index','overflow-x','overflow-y','white-space', 'clip','float','clear','cursor','list-style-image','list-style-position', 'list-style-type','marker-offset']; var len = attr.length, obj = {}; for (var i = 0; i < len; i++) obj[attr[i]] = jQuery.fn.css2.call(this, attr[i]); return obj; } Edit: I've now been using the code above for awhile. It works well and behaves exactly like the original css method with one exception: if 0 args are passed, it returns the computed style object. As you can see, it immediately calls the original css method if that's the case that applies. Otherwise, it gets the computed styles of all the listed properties (gathered from Firebug's computed style list). Although it's getting a long list of values, it's quite fast. Hope it's useful to others.

  • ASP.NET MVC2: Can you get ModelMetadata.ContainerType from within a collection?

    - by CodeSponge
    I'm trying to call DisplayFor and DisplayForModel to iterate an IEnumerable< with various element types from within a view. I have Templates defined for each element/Model type. What I would like to do is check the ViewData.ModelMetadata.ContainerType from within the Template so that Template can determine if it was called as part of a collection. A simple example: Index1.aspx: To render a collection of Foos. <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<Foo>>" %> <asp:Content ContentPlaceHolderID="MainPlaceHolder" runat="server"> <ul><%:Html.DisplayForModel()%></ul> </asp:Content> Index2.aspx: To render a Foo. <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Foo>" %> <asp:Content ContentPlaceHolderID="MainPlaceHolder" runat="server"> <%:Html.DisplayForModel()%> </asp:Content> Shared\DisplayTemplates\Foo.ascx: A context aware Template for Foo. <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Foo>" %> <% var tag = typeof(IEnumerable).IsAssignableFrom(ViewData.ModelMetaData.ContainerType) ? "li" : "div"; %> <<%:tag%>><%:Model.Name%></<%:tag%>> The problem with this example is that ViewData.ModelMetaData.ContainerType is null in the Template when resolved though Index1.aspx. From what I've read on Brad Wilson post and others it has to do with the use of IEnumerable and its being an interface. Is there a way to insure that the ContainerType is set? Perhaps by creating a ModelMetadataProviders? I looked into that breifly but it appears the ContainerType value is determined before and then passed to the Provider. Any suggestions would be appreciated.

  • Jquery hasClass conditional not working

    - by Wade D Ouellet
    Hey, I have my site going here: http://www.treethink.com I am trying to make it so when a navigation item is clicked, it retracts the news ticker on the right and then doesn't run any of the extracting/timer functions anymore. I got it to retract but it still extracts. How I am doing it is I am adding a "noTicker" class with the nav buttons and removing it with colorbox's close button. The function runs on the page initially and if there isn't a "noTicker" class it runs the news ticker as planned. When a nav or close button is clicked it runs the function again which checks again to see if it has that class. So if it has the class it should retract (which it is so that must mean it's adding the class properly) and then not run any of the timer functions, but it still runs the timer functions for some reason. Here is my jQuery. /* Initially hide all news items */ $('#ticker1').hide(); $('#ticker2').hide(); $('#ticker3').hide(); var randomNum = Math.floor(Math.random()*3); /* Pick random number */ newsTicker(); function newsTicker() { if (!$("#ticker").hasClass("noTicker")) { $("#ticker").oneTime(2000,function(i) { /* Do the first pull out once */ $('div#ticker div:eq(' + randomNum + ')').show(); /* Select div with random number */ $("#ticker").animate({right: "0"}, {duration: 800 }); /* Pull out ticker with random div */ }); $("#ticker").oneTime(15000,function(i) { /* Do the first retract once */ $("#ticker").animate({right: "-450"}, {duration: 800}); /* Retract ticker */ $("#ticker").oneTime(1000,function(i) { /* Afterwards */ $('div#ticker div:eq(' + (randomNum) + ')').hide(); /* Hide that div */ }); }); $("#ticker").everyTime(16500,function(i) { /* Everytime timer gets to certain point */ /* Show next div */ randomNum = (randomNum+1)%3; $('div#ticker div:eq(' + (randomNum) + ')').show(); $("#ticker").animate({right: "0"}, {duration: 800}); /* Pull out right away */ $("#ticker").oneTime(15000,function(i) { /* Afterwards */ $("#ticker").animate({right: "-450"}, {duration: 800});/* Retract ticker */ }); $("#ticker").oneTime(16000,function(i) { /* Afterwards */ /* Hide all divs */ $('#ticker1').hide(); $('#ticker2').hide(); $('#ticker3').hide(); }); }); } else { $("#ticker").animate({right: "-450"}, {duration: 800}); /* Retract ticker */ $("#ticker").oneTime(1000,function(i) { /* Afterwards */ $('div#ticker div:eq(' + (randomNum) + ')').hide(); /* Hide that div */ }); } } /* when nav item is clicked re-run news ticker function but give it new class to prevent activity */ $("#nav li").click(function() { $("#ticker").addClass("noTicker"); newsTicker(); }); /* when close button is clicked re-run news ticker function but take away new class so activity can start again */ $("#cboxClose").click(function() { $("#ticker").removeClass("noTicker"); newsTicker(); }); Thanks, Wade

  • JQuery and PHP display problem

    I'm new to JQuery but for some reason I cant get the php code to display correctly when I put it in my JQuery script. The php code will display correctly when its not in the JQuery code can someone help me fix my JQuery code so it will display my PHP code correctly? Here is the JQuery and PHP code. var count = 0; $(function(){ $('p#add_field').click(function(){ count += 1; $('#container').append( '<input type="text" name="sk" id="sk" />' + '<label for="exp">Exp: </label>' + '<?php' + 'echo \'<select id="exp" name="exp">\' .

  • Need help with implementation of the jQuery LiveUpdate routine

    - by miCRoSCoPiC_eaRthLinG
    Hey all, Has anyone worked with the LiveUpdate function (may be a bit of a misnomer) found on this page? It's not really a live search/update function, but a quick filtering mechanism for a pre-existing list, based on the pattern you enter in a text field. For easier reference, I'm pasting the entire function in here: jQuery.fn.liveUpdate = function(list){ list = jQuery(list); if ( list.length ) { var rows = list.children('li'), cache = rows.map(function(){ return this.innerHTML.toLowerCase(); }); this .keyup(filter).keyup() .parents('form').submit(function(){ return false; }); } return this; function filter(){ var term = jQuery.trim( jQuery(this).val().toLowerCase() ), scores = []; if ( !term ) { rows.show(); } else { rows.hide(); cache.each(function(i){ var score = this.score(term); if (score > 0) { scores.push([score, i]); } }); jQuery.each(scores.sort(function(a, b){return b[0] - a[0];}), function(){ jQuery(rows[ this[1] ]).show(); }); } } }; I have this list, with members as the ID. And a text field with say, qs as ID. I tried binding the function in the following manner: $( '#qs' ).liveUpdate( '#members' ); But when I do this, the function is called only ONCE when the page is loaded (I put in some console.logs in the function) but never after when text is keyed into the text field. I also tried calling the routine from the keyup() function of qs. $( '#qs' ).keyup( function() { $( this ).liveUpdate( '#members' ); }); This ends up going into infinite loops (almost) and halting with "Too much recursion" errors. So can anyone please shed some light on how I am supposed to actually implement this function? Also while you are at it, can someone kindly explain this line to me: var score = this.score(term); What I want to know is where this member method score() is coming from? I didn't find any such method built into JS or jQuery. Thanks for all the help, m^e

  • jQyery bind on ajax load() event

    - by Andrei C
    Hi guys. I have a page which display multiple blocks with results details. Inside each block I have some tags with thichbox jQuery plugin attached( class="thichbox"). http://jquery.com/demo/thickbox/ here is an example of one kind of ampersant tag: <a class="thickbox" title="Please Sign In" href="userloginredir.php?height=220&width=350&deal=3"> Problem comes when I added a jQuery pagination to the page because of to many results displaying on the page. The div component with the results inside is updated through ajax load() event. Below is the pagination script. $(document).ready(function(){ //References var pages = $("#menu_deals li"); var loading = $("#loading_deals"); var content = $("#content_deals"); //show loading bar function showLoading(){ loading .css({visibility:"visible"}) .css({opacity:"1"}) .css({display:"block"}) ; } //hide loading bar function hideLoading(){ loading.fadeTo(1000, 0); }; //Manage click events pages.live('click',function(){ //show the loading bar showLoading(); //Highlight current page number pages.css({'background-color' : ''}); $(this).css({'background-color' : 'yellow'}); //Load content var pageNum = this.id; var targetUrl = "ajax_search_results.php?page=" + pageNum + "&" + $("#dealsForm").serialize() + " #content_d"; content.load(targetUrl, hideLoading); }); //default - 1st page $("#1").css({'background-color' : 'yellow'}); var targetUrl = "ajax_search_results.php?page=1&" + $("#dealsForm").serialize() + " #content_d"; showLoading(); content.load(targetUrl, hideLoading); }); When I added pagination(code above), the thickbox events are not recognized anymore and instead of poping out a window with the login form inside it opens the results in new page (is acting like clicking on a normal link) From my jQuery knowledge this means that the components are not defined in the DOM because the content is updated after document ready triggered. I'm trying to bind the load event with something like this: content.bind('load',???); But I don't know how to pass the load params, targetUrl and the callback function hideLoading, when binding the load event. Please help me out in this matter, already took me more time than possible allowed. Thank you!

  • GridView paging inside an UpdatePanel or PlaceHolder components

    - by John
    Hello, I'm new to ASP.NET. Im developing ASP.NET C# web form which creating GridView components dynamically and filling them using the data received from my webservice. I'm creating these GridView components programmatically in server-side (cs file)- it has to be flexible - 1 GridView and sometimes 10 GridView components. The problem occurs when I'm trying to add pagination - whenever the user clicks the "next" page, the whole page is getting refreshed because of a postBack and I'm loosing all my data and the page returns Blank/Empty. I used PlaceHolder to hold the GridView components, while searching for a solution, I found UpdatePanel as a better alternative - as far as I understand the page can be partially refreshed - which means that only the UpdatePanel has to be refreshed...but it doesn't work. The following code sample is my TEST, the UpdatePanel is the only component initiated in the client side (aspx page), the rest initiated programmatically in CS. how can I solve the issue described above? Why does the whole page is getting refreshed and I'm loosing my data? can you recommend another way? can provide me with any code sample? If I'm not rebuilding the GridView, it doesn't work... Here is my Default.aspx.cs: public partial class TestAjaxForm : System.Web.UI.Page { DataTable table; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) bindGridView(); } public void bindGridView() { GridView gridView1 = new GridView(); gridView1.AutoGenerateColumns = true; gridView1.PageSize = 2; gridView1.AllowPaging = true; gridView1.PagerSettings.Mode = PagerButtons.Numeric; gridView1.PagerSettings.Position = PagerPosition.Bottom; gridView1.PagerSettings.PageButtonCount = 10; gridView1.PageIndexChanging += new GridViewPageEventHandler(this.GridView1_PageIndexChanging); table = new DataTable(); table.Columns.Add("FirstName"); table.Columns.Add("LastName"); DataRow row = table.NewRow(); row["FirstName"] = "John"; row["LastName"] = "Johnoson"; table.Rows.Add(row); row = table.NewRow(); row["FirstName"] = "Johnny"; row["LastName"] = "Marley"; table.Rows.Add(row); row = table.NewRow(); row["FirstName"] = "Kate"; row["LastName"] = "Li"; table.Rows.Add(row); panel.ContentTemplateContainer.Controls.Add(gridView1); gridView1.DataSource = table; gridView1.DataBind(); } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { GridView gridView1 = (GridView)sender; gridView1.PageIndex = e.NewPageIndex; gridView1.DataSource = table; gridView1.DataBind(); } } Please help me, Thank you.

  • How to merge jquery autocomplete and fcbkListSelection functionality?

    - by Ben
    Initial caveat: I am a newbie to jquery and javascript. I started using the autocomplete jquery plugin recently from bassistance.de. Yesterday, I found the fcbkListSelection plugin (http://www.emposha.com/javascript/fcbklistselection-like-facebook-friends-selector.html) and am using it to include a selector in my application. What I now want to do is to merge the 2 pieces of functionality since there are lots of items in my selector list. To be more specific, I want to put a "Filter by Name" text box above the facebook list selection object in my html. When the user types a few characters into the "Filter by Name" text box, I want the items in the Facebook list selector to only show the items that contain the typed characters -- kind of like what autocomplete does already, but rather than the results showing below the text input box, I want them to dynamically update the facebook list object. Is this possible and relatively straightforward? If so, can somebody please describe how to do it? If not, is there an easier way to approach this? Thanks! OK, to Spencer Ruport's comment, I guess I may have a more specific question already. Below is the current Javascript in my HTML file (angle brackets represent Django tags). #suggest1 and #fcbklist both do their separate pieces, but how do I get them to talk to each other? Do I need to further write javascript in my HTML file, or do I need to customize the guts of the plugins' .js? Does this help elaborate? $(document).ready(function() { var names = []; var count = 0; {% for a, b, c in friends_for_picker %} names[count] = "{{ b }}"; count = count+1; {% endfor %} function findValueCallback(event, data, formatted) { $("<li>").html( !data ? "No match!" : "Selected: " + formatted).appendTo("#result"); } function formatItem(row) { return row[0] + " (<strong>id: " + row[1] + "</strong>)"; } function formatResult(row) { return row[0].replace(/(<.+?>)/gi, ''); } $("#suggest1").autocomplete(names, { multiple: true, mustMatch: false, autoFill: true, matchContains: true, }); //id(ul id),width,height(element height),row(elements in row) $.fcbkListSelection("#fcbklist","575","50","4"); });

  • Move options between multiple lists

    - by Martha
    We currently have a form with the standard multi-select functionality of "here are the available options, here are the selected options, here are some buttons to move stuff back and forth." However, the client now wants the ability to not just select certain items, but to also categorize them. For example, given a list of books, they want to not just select the ones they own, but also the ones they've read, the ones they would like to read, and the ones they've heard about. (All examples fictional.) Thankfully, a selected item can only be in one category at a time. I can find many examples of moving items between listboxes, but not a single one for moving items between multiple listboxes. To add to the complication, the form needs to have two sets of list+categories, e.g. a list of movies that need to be categorized in addition to the aforementioned books. EDIT: Having now actually sat down to try to code the non-javascripty bits, I need to revise my question, because I realized that multiple select lists won't really work from the "how do I inform the server about all this lovely new information" standpoint. So the html code is now a pseudo-listbox, i.e. an unordered list (ul) displayed in a box with a scrollbar, and each list item (<li>) has a set of five radio buttons (unselected/own/read/like/heard). My task is still roughly the same: how to take this one list and make it easy to categorize the items, in such a way that the user can tell at a glance what is in what category. (The pseudo-listbox has some of the same disadvantages as a multi-select listbox, namely it's hard to tell what's selected if the list is long enough to scroll.) The dream solution would be a drag-and-drop type thing, but at this point even buttons would be OK. Another modification (a good one) is that the client has revised the lists, so the longest is now "only" 62 items long (instead of the many hundreds they had before). The categories will still mostly contain zero, one, or two selected items, possibly a couple more if the user was overzealous. As far as OS and stuff, the site is in classic asp (quit snickering!), the server-side code is VBScript, and so far we've avoided the various Javascript libraries by the simple expedient of almost never using client-side scripting. This one form for this one client is currently the big exception. Give 'em an inch and they want a mile... Oh, and I have to add: I suck at Javascript, or really at any C-descendant language. Curly braces give me hives. I'd really, really like something I can just copy & paste into my page, maybe tweak some variable names, and never look at it again. A girl can dream, can't she? :) [existing code deleted because it's largely irrelevant.]

  • HTML: Include, or exclude, optional closing tags?

    - by Ian Boyd
    Some HTML1 closing tags are optional, i.e.: </HTML> </HEAD> </BODY> </P> </DT> </DD> </LI> </OPTION> </THEAD> </TH> </TBODY> </TR> </TD> </TFOOT> </COLGROUP> Note: Not to be confused with closing tags that are forbidden to be included, i.e.: </IMG> </INPUT> </BR> </HR> </FRAME> </AREA> </BASE> </BASEFONT> </COL> </ISINDEX> </LINK> </META> </PARAM> Note: xhtml is different from HTML. xhtml is a form of xml, which requires every element have a closing tag. A closing tag can be forbidden in html, yet mandatory in xhtml. Are the optional closing tags ideally included, but we'll accept them if you forgot them, or ideally not included, but we'll accept them if you put them in In other words, should i include them, or should i not include them? The HTML 4.01 spec talks about closing element tags being optional, but doesn't say if it's preferable to include them, or preferable to not include them. On the other hand, a random article on DevGuru says: The ending tag is optional. However, it is recommended that it be included. The reason i ask is because you just know it's optional for compatibility reasons; and they would have made them (mandatory | forbidden) if they could have. Put it another way: What did HTML 1, 2, 3 do with regards to these, now optional, closing tags. What does HTML 5 do? And what should i do? Footnotes 1HTML 4.01

  • How to efficently build an interpreter (lexer+parser) in C?

    - by Rizo
    I'm trying to make a meta-language for writing markup code (such as xml and html) wich can be directly embedded into C/C++ code. Here is a simple sample written in this language, I call it WDI (Web Development Interface): /* * Simple wdi/html sample source code */ #include <mySite> string name = "myName"; string toCapital(string str); html { head { title { mySiteTitle; } link(rel="stylesheet", href="style.css"); } body(id="default") { // Page content wrapper div(id="wrapper", class="some_class") { h1 { "Hello, " + toCapital(name) + "!"; } // Lists post ul(id="post_list") { for(post in posts) { li { a(href=post.getID()) { post.tilte; } } } } } } } Basically it is a C source with a user-friendly interface for html. As you can see the traditional tag-based style is substituted by C-like, with blocks delimited by curly braces. I need to build an interpreter to translate this code to html and posteriorly insert it into C, so that it can be compiled. The C part stays intact. Inside the wdi source it is not necessary to use prints, every return statement will be used for output (in printf function). The program's output will be clean html code. So, for example a heading 1 tag would be transformed like this: h1 { "Hello, " + toCapital(name) + "!"; } // would become: printf("<h1>Hello, %s!</h1>", toCapital(name)); My main goal is to create an interpreter to translate wdi source to html like this: tag(attributes) {content} = <tag attributes>content</tag> Secondly, html code returned by the interpreter has to be inserted into C code with printfs. Variables and functions that occur inside wdi should also be sorted in order to use them as printf parameters (the case of toCapital(name) in sample source). I am searching for efficient (I want to create a fast parser) way to create a lexer and parser for wdi. Already tried flex and bison, but as I am not sure if they are the best tools. Are there any good alternatives? What is the best way to create such an interpreter? Can you advise some brief literature on this issue?

  • How can I stop Flash from changing indent when user Clicks on hyperlink in TextField?

    - by Paul Chernoch
    I have a TextField which I initialize by setting htmlText. The text has anchor tags (hyperlinks). When a user clicks on the hyperlink, the indentation of the second and subsequent lines in the paragraph changes. Why? How do I stop it? My html has an image at the beginning of the line, followed by the tag, followed by more text. To style the hyper links to look blue always and underlined when the mouse is over them, I do this: var css:StyleSheet = new StyleSheet(); css.parseCSS("a {color: #0000FF;} a:hover {text-decoration: underline;}"); stepText.styleSheet = css; stepText.htmlText = textToUse; stepText.visible = true; Here is a fragment of the html text (with newlines and exrta whitespace added to improve readability - originally it was one long line): <textformat indent="-37" blockindent="37" > <img src="media/interface/level-1-bullets/solid-circle.png" align="left" hspace="8" vspace="1"/> American Dental Association.

Retrieved 11/24/08, from <a href="http://www.ada.org/public/topics/cleaning_faq.asp" target="_blank">http://www.ada.org/public/topics/cleaning_faq.asp </a> </textformat> <br/> As it turns out, the text field is of a width such that it wraps and the second line starts with "Retrieved 11/24/08". Clicking on the hyper link causes this particular line to be indented. Subsequent paragraphs are not affected. ASIDE: The image is a list bullet about 37 pixels wide. (I used images instead of li tags because Flash does not allow nested lists, so I faked it using a series of images with varying amounts of whitespace to simulate three levels of indentation.) IDEA: I was thinking of changing all hyperlinks to use "event:" as the URL protocol, which causes a TextEvent.LINK event to be triggered instead of following the link. Then I would have to open the browser in a second call. I could use this event handler to set the html text to itself, which might clear the problem. (When I switch pages in my application and then come back to the page, everything is OKAY again.) PROBLEM: If I use the "event:" protocol and user tries the right-mouse button click, they will get an error, or so I am told. (See http://www.blog.lessrain.com/as3-texteventlink-and-contextmenu-incompatibilities/ ) I do not like this trade-off.
