  • Print <div id=printarea></div> only?

    - by noesgard
    How do I print the indicated div (without manually disabling all other content on the page)? I want to avoid a new preview dialog, so crating a new window with this content is not useful... The page contains a couple of tables, one of them contains the div I want to print - the table is styled with visual styles for the web, that should not be shown in print....

  • Jquery Hidden Field in Table

    - by zSysop
    Hi all, I was wondering if anyone knew of a way to access a hidden field (by client id) within a table row using jquery. $("#tblOne").find("tr").click(function() { var worker = $(this).find(":input").val(); }); I find that the above works for a row that has only one input, but i need some help figuring out a way to get the value by the inputs name. Here's the example of a table row. How would i access the two fields by their id's? <table id="tblOne"> <tr> <td> <asp:HiddenField id="hdnfld_Id" Text='<% Eval("ID") %>'></asp:HiddenField> </td> <td> <asp:HiddenField id="hdnfld_Id2" Text='<% Eval("ID2") %>'></asp:HiddenField> </td> </tr> </table>

  • update text on click of date with jQuery UI datepicker

    - by stevoyoung
    I have two related questions... How do I update an HTML element (let's say a p tag) with the correct date when I click on a day in the jQuery UI datepicker plug in? If I have another way to selecte a date aside from the datepicker, how do I then update the datepicker's selected date (it's adds a class of "ui-state-active" to the date)?

  • In Node.js, how can I load my modules once and then use them throughout the app?

    - by TIMEX
    I want to create one global module file, and then have all my files require that global module file. Inside that file, I would load all the modules once and export a dictionary of loaded modules. How can I do that? I actually tried creating this file...and every time I require('global_modules'), all the modules kept reloading. It's O(n). I want the file to be something like this (but it doesn't work): //global_modules.js - only load these one time var modules = { account_controller: '/account/controller.js', account_middleware: '/account/middleware.js', products_controller: '/products/controller.js', ... } exports.modules = modules;

  • Backbone: Easiest way to maintain reference to 'this' for a Model inside callbacks

    - by Garrett
    var JavascriptHelper = Backbone.Model.extend("JavascriptHelper", {}, // never initialized as an instance { myFn: function() { $('.selector').live('click', function() { this.anotherFn(); // FAIL! }); }, anotherFn: function() { alert('This is never called from myFn()'); } } ); The usual _.bindAll(this, ...) approach won't work here because I am never initializing this model as an instance. Any ideas? Thanks.

  • Problems with my JS array undefined x 7

    - by Dave
    I have an array im trying to loop through to create a new type of array specific to my current page. My array looks like this: //$_SESSION['data'] = Array ( [0] => 1 [1] => 0 [2] => Tom [8] => 1 [4] => 1 [5] => Array ( [7] => Array ( [0] => Andrew [1] => 1 [2] => 1 [4] => 0 [5] => avatar.jpg [6] => 1 ) ) [6] => Array ( [0] => 1 [1] => 2 ) ) So in my JS file i have this: var stats = <? echo $_SESSION['data'][5]); ?> ; //this is the array my_data = new Array(); for(var key in stats){ if(key in my_data){} else { //prevent double entry my_data[key] = new Array(); my_data[key][0] = stats[key][6]; my_data[key][1] = stats[key][5]; my_data[key][2] = stats[key][2]; my_data[key][3] = stats[key][0]; } } console.log(my_data); Now in console.log i get this : [undefined × 7, Array[4] 0: "1" 1: "avatar.jpg" 2: "1" 3: "Andrew" length: 4 __proto__: Array[0] ] I'm wondering why it is saying undefined x7?

  • Applying a partial gaussian like blur to a background image

    - by Andy
    I have and image which gets stretched to its full background, regardless of the monitor size. What i need to do is apply cross-browser blur above this image on only a portion of the left hand side. So it gives the appearance of a blur on the image. If i apply it to the image then when the screen resolution changes size so does the size of the blur. Any help would be great. Cheers

  • remove/restore elements, maintaining their events and element's children

    - by Emin
    I came to a situation where I need to edit the following in a way that, on some event (lets assume the 'click' event in this case) I need to remove (or unwrap?) the .container and the .header and have the .itemlist still visible/available on the page. And then, I need to restore .container and .header back again on some other event, while still maintain the event listeners on the a tags, and if possible, without removing the said items from the DOM. Is this possible? <ul class="container"> <li class="header"><a href="#">delete</a> | <a href="#">edit</a></li> <ul class="itemlist"> <li>some item</li> <li>some other item</li> </ul> </ul>

  • CakePHP: Ajax view problem (nothing in the view showing)

    - by Adim
    I created a function in my controller called addToPlaylist($songName). I wanted to add these song names to an array and then a session variable using an Ajax call. The first time i did this i got an error saying i do not have a template file to display in the chosen div ("add_to_playlist.ctp was missing"). I created this file and everything seemed to be working correctly. Basically I went to bed woke up and it is broken (it is possible I changed something before I went to bed). The problem now is that it does not show anything when i click the ajax link. when i click on the ajax link it seems to call the function but nothing displays in the view (except debug info) even when i delete the view (add_to_playlist.ctp) i get no errors, I just see debug info now.

  • POST data disapearing on large file upload

    - by DfKimera
    I'm having issues with a file uploading utility in my PHP application. When sending large files (9MB+) over the form, I get a very odd behaviour: the POST data I've included in the form dissapears, including the file information. I've already increased all PHP limits I could (time limit, max input time, post max size, memory limit and upload max filesize) and I still can't get the proper behaviour. I've tried replacing the regular HTTP forms with a Flash-based solution (SWFUpload, www.swfupload.org), still the same behaviour. I've tried multiple files of similar sizes and its definitely not a particular file issue. I've debugged the POST vars sent using Firebug, and the correct variables are still there in the header, together with the file. What could be going on here?

  • How to force delete cookies even if one window is still open?

    - by medopal
    Apparently in IE8, there is this option 'Preserve Favorites website data', even if I uncheck it the browser will still keep the cookies until the last window is closed. Problem scenario. say I logged in to somesite.com, then without out logging out, I closed the window, but there was still another IE8 window open. In this case IE8 will keep the cookies of this site. So If I opened the site again (same window or another) the site won't ask for login info. The client wants the web application to be logged off as soon as the user closes the browser. Can I force delete the cookies IE8 is saving? or maybe I can stop the user from closing the window until I simulate a click on logout button?

  • Dual AJAX Requests at different times

    - by Nik
    Alright, I'm trying to make an AJAX Chat system that polls the chat database every 400ms. That part is working, the part of which isn't is the Active User List. When I try to combine the two requests, the first two requests are made, then the whole thing snowballs and the usually timed (12 second) Active User List request starts updating every 1ms and the first request NEVER happens again. Displayed is the entire AJAX code for both requests: var waittime=400;chatmsg=document.getElementById("chatmsg"); room = document.getElementById("roomid").value; chatmsg.focus() document.getElementById("chatwindow").innerHTML = "loading..."; document.getElementById("userwindow").innerHTML = "Loading User List..."; var xmlhttp = false; var xmlhttp2 = false; var xmlhttp3 = false; function ajax_read(url) { if(window.XMLHttpRequest){ xmlhttp=new XMLHttpRequest(); if(xmlhttp.overrideMimeType){ xmlhttp.overrideMimeType('text/xml'); } } else if(window.ActiveXObject){ try{ xmlhttp=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try{ xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e){ } } } if(!xmlhttp) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState==4) { document.getElementById("chatwindow").innerHTML = xmlhttp.responseText; setTimeout("ajax_read('methods.php?method=r&room=" + room +"')", waittime); } } xmlhttp.open('GET',url,true); xmlhttp.send(null); } function user_read(url) { if(window.XMLHttpRequest){ xmlhttp3=new XMLHttpRequest(); if(xmlhttp3.overrideMimeType){ xmlhttp3.overrideMimeType('text/xml'); } } else if(window.ActiveXObject){ try{ xmlhttp3=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try{ xmlhttp3=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e){ } } } if(!xmlhttp3) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } xmlhttp3.onreadystatechange = function() { if (xmlhttp3.readyState==4) { document.getElementById("userwindow").innerHTML = xmlhttp3.responseText; setTimeout("ajax_read('methods.php?method=u&room=" + room +"')", 12000); } } xmlhttp3.open('GET',url,true); xmlhttp3.send(null); } function ajax_write(url){ if(window.XMLHttpRequest){ xmlhttp2=new XMLHttpRequest(); if(xmlhttp2.overrideMimeType){ xmlhttp2.overrideMimeType('text/xml'); } } else if(window.ActiveXObject){ try{ xmlhttp2=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try{ xmlhttp2=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e){ } } } if(!xmlhttp2) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } xmlhttp2.open('GET',url,true); xmlhttp2.send(null); } function submit_msg(){ nick = document.getElementById("chatnick").value; msg = document.getElementById("chatmsg").value; document.getElementById("chatmsg").value = ""; ajax_write("methods.php?method=w&m=" + msg + "&n=" + nick + "&room=" + room + ""); } function keyup(arg1) { if (arg1 == 13) submit_msg(); } var intUpdate = setTimeout("ajax_read('methods.php')", waittime); var intUpdate = setTimeout("user_read('methods.php')", waittime);

  • Is it possible to drag an HTML element out of another element and trigger a change with jQuery?

    - by blackrobot
    I have a container element that you can drag objects around in. I want it it so that if you drag an element out of the container (when the mouse crosses the border of the containing div) the element you're dragging to change. How do I arrange this? $("#container img").draggable({ helper: 'clone', zIndex: 100 }); Once the image crosses the bounds of "#container" I should be able to change the image source.

  • Click Function on jQuery plugin only allows for single click

    - by user1427307
    I've created this simple plugin to add multiple animations on click but the problem is that once the object is clicked it can not repeat the animation by clicking again, i can't figure out why the added class is not removing itself after the click function is complete to allow it to be clicked again and repeat.. any suggestions? (function($) { $.fn.vivify = function(options) { var defaults = { animation: 'bounce', }; var options = $.extend(defaults, options); return this.each(function() { var o = options; var obj = $(this); var animation = o.animation; obj.bind("click", function() { obj.addClass(o.animation); obj.addClass('vivify'); }, function() { obj.removeClass(o.animation); }); }) } })(jQuery);

  • Simple Form validation failing Backbone

    - by Corey Buchillon
    Im not exactly adept at coding so Im probably missing something, but my view here is failing to refuse submission when one or both of the fields are empty. I have a feeling something isnt connected right to my template for the row and the view of the form Form = Backbone.View.extend({ //form vie el: '.item-form', initialize: function(){ }, events: { 'click #additem': 'addModel' }, addModel: function(itemName, price){ // simple validation before adding to collection if (itemName !="" && price !="" ){ var item = new Item({ itemName: this.$("#item").val(), price: this.$("#price").val()}); items.add(item); $("#message").html("Please wait; the task is being added."); item.save(null, {success: function (item, response,options) { item.id= item.attributes._id.$id; item.attributes.id = item.attributes._id.$id; new ItemsView({collection: items}); $("#message").html(""); } }); this.$("#item").val(''); this.$("#price").val(''); } else { alert('Please fill in both fields'); } } }); and HTML <table class="itemTable"> <thead> <tr> <th>Item</th> <th>Price</th> <th></th> </tr> </thead> <tbody class="tableBody"> <script type="text/template" id="table-row"> <td><%= itemName %></td> <td><%= price %></td> <td><button class="complete">Complete</button> <button class="remove">Remove</button></td> </script> </tbody> </table> <form class="item-form"> <input type="text" name="item" id="item" placeholder="Item"/> <!-- goes to itemName in the template for the body --> <input type="text" name="price" id="price" placeholder="Price" /><!--goes to price in the template for the body --> <button type="button" id="additem">Add</button> </form> <div id="message"></div>

  • 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. Thanks in advance for any help.

  • localStorage not working in IE9 and Firefox

    - by maha
    I am working with localStorage. My code is perfectly working in Chrome, but not in IE9 and Firefox. Here is the code: document.addEventListener("DOMContentLoaded", restoreContents, false); document.getElementsByTagName("body")[0].onclick=function(){saveContents('myList','contentMain', event, this);}; function amIclicked(e, eleObject) { alert("amIClicked"); e = e || event; var target = e.target || e.srcElement; alert("target = " + target.id); if(target.id=='pageBody' || target.id=='Save') return true; else return false; } function saveContents(e, d, eveObj, eleObject) { //alert("saveContents"); if (amIclicked(eveObj, eleObject)) { var cacheValue = document.getElementById(e).innerHTML; var cacheKey = "key_" + selectedKey; var storage = window.localStorage; //alert ("cacheKey = " + cacheKey + " ,cacheValue = " + cacheValue); if(typeof(Storage)!=="undifined"){ localStorage.setItem("cacheKey","cacheValue"); } //alert ("Saved!!"); var dd = document.getElementById(d); //document.getElementById("contentMain").style.display == "none"; dd.style.display = "none"; } } function restoreContents(e,k) { //alert("test"); if(k.length < 1) { return; } var mySavedList = localStorage["key_" + k]; if (mySavedList != undefined) { document.getElementById(e).innerHTML = mySavedList; } } <a onclick="ShowContent('contentMain','myList','Sample_1'); return true;" href="#" >Sample 1</a><br/><br/> <a onclick="ShowContent('contentMain','myList','Sample_2'); return true;" href="#" >Sample 2</a><br/><br/> <div style="display:none;display:none;position:absolute;border-style: solid;background-color: white;padding: 5px;"id="contentMain"> <ol id="myList" contenteditable="true"> <li>Enter Content here</li> </ol> <!--<input id="editToggleButton" type="button" value="Edit"/>--> </div> When I debugging in Iexplore Iam getting the error as SCRIPT5007: Unable to get value of the property 'length': object is null or undefined sample_1.html, line 157 character 3 Thanks

  • jQuery ajax returns

    - by Tom
    I think this will be some obvious problem, but I cannot figure it out. I hope someone can help me. So I have a slider with 3 slides - Intro, Question, Submit Now I want to make sure that if the question is answered wrong people cannot slide to Submit. The function to move slide is like this: function changeSlide(slide){ // In case current slide is question check the answer if (jQuery('.modalSteps li.current',base).hasClass('questionStep')){ checkAnswer(jQuery('input[name="question_id"]',base).val(), jQuery('input[name="answer"]:checked',base).val()); } jQuery('.modalSteps li.current',base).fadeOut('fast',function(){ jQuery(this).removeClass('current'); jQuery(slide).fadeIn('fast',function(){ jQuery(slide).addClass('current'); }); }); // In case the new slide is question, load the question if (jQuery(slide).hasClass('questionStep')){ var country = jQuery('input[name="country"]:checked',base).val(); loadQuestion(country); } } Now as you can see on first lines, I am calling function checkAnswer, which takes id of question and id of answer and pass it to the AJAX call. function checkAnswer(question, answer){ jQuery.ajax({ url: window.base_url+'ajax/check_answer/'+question+'/'+answer+'/', success: function(data){ if (!data.success){ jQuery('.question',base).html(data.message); } } }); } The problem i am having is that I cannot say if(checkAnswer(...)){} Because of Ajax it always returns false or undefined. What I need is something like this: function changeSlide(slide){ // In case current slide is question check the answer if (jQuery('.modalSteps li.current',base).hasClass('questionStep')){ if (!checkAnswer(jQuery('input[name="question_id"]',base).val(), jQuery('input[name="answer"]:checked',base).val())){ return false; } } ... So it will prevent the slide from moving on. Now when Im thinking about it, I will probably have slide like "Wrong answer" so I could just move the slide there, but I would like to see the first solution anyway. Thank you for tips

  • Canvas and HTML5: Supported Browsers?

    - by Paddy
    I am looking at using HTML5 Canvas element for my upcoming project. I want to know what all major browsers (including the versions!, cos i know that the latest builds do support canvas) support the Canvas tag. I don't give a damn about IE. So don't bother reporting IE. :) In this tutorial Drawing shapes - MDC, the quadraticCurveTo section says: quadraticCurveTo(cp1x, cp1y, x, y) // BROKEN in Firefox 1.5 (see work around below) Does that mean that Canvas is supported on Firefox 1.5 and above too?
