    - by Prathiba
    I'm using twitter bootstrap in my application. i gave e.preventDefault for link button in $(document).reday(), but it is not working. Here is my code: Master page: <a id="lnkLogout" href="javascript:void(0);" onclick="PageLogout();"><i class="icon-off"> </i>Logout</a> <script type="text/javascript" language="javascript"> $(document).ready(function () { $('#lnkLogout').click(function (e) { e.preventDefault(); }); }); function PageLogout() { //Code for logout from the application.... } </script> SampleDefaultPage.aspx : <div class="row-fluid"> <div class="form-horizontal"> <h4 class="header blue bolder smaller"> Contact</h4> <div class="control-group"> <label for="form-field-email" class="control-label"> Email</label> <div class="controls"> <input type="text" style="width:200px;" data-val="true" data-val-required="Mobile Number is required." id="txtEmail"> <div class="space-3"> </div> <span data-valmsg-replace="true" data-valmsg-for="txtEmail" class="field-validation-valid text-warning red"></span> </div> </div> <div class="control-group"> <label for="form-field-website" class="control-label"> Phone Number</label> <div class="controls"> <input type="text" style="width:200px;" id="txtPhno"> </div> </div> </div> I have given txtEmail as mandatory field. if i left that field blank and click on Logout button in Master page, it says txtEmail is required. i dint do any validation in Logout onclick event. I have given preventDefault for Logout link. But still facing an issue. I should be able to logout even though txtEmail is left blank. Thank you all in advance for your response.

  • Drawing straight lines in JavaScript

    - by Shawn31313
    I'm just trying to draw a line with JavaScript. I would like it to be like this: http://deepliquid.com/projects/blog/arrows2.html My version: http://jsfiddle.net/shawn31313/qsWML/5/show Doesn't work too well and I don't know how to get it too work. It must be an issue in my JavaScript. This my code: $(document).ready(function() { var dragStatus = 2, getPos, giveRandomID; $(document).mousedown(function(event) { dragStatus = 0; getPos = { top: event.clientY, left: event.clientX }; giveRandomID = Math.floor(Math.random() * 99999); }); $(document).mousemove(function() { var line = $('#line' + giveRandomID); if (dragStatus == 0) { $('body').append("<div id='line" + giveRandomID + "' style='position:absolute;top:" + getPos.top + "px;left:" + getPos.left + "px;background:black;width:2px;height:5px'></div>"); dragStatus = 1; } if (dragStatus == 1) { if (event.clientX > getPos.left) { line.css({ left: getPos.left, width: event.clientX - getPos.left }); } else { line.css({ left: event.clientX, width: getPos.left - event.clientX }); } if (event.clientY > getPos.top) { line.css({ top: getPos.top - Math.abs((event.clientY - getPos.top) * 2), '-webkit-transform': 'rotate(' + (event.clientY - getPos.top) + 'deg)' }); } else { line.css({ top: getPos.top + Math.abs((getPos.top - event.clientY) * 2), '-webkit-transform': 'rotate(' + (getPos.top - event.clientY) + 'deg)' }); } //for DEG "-" Top-Math.abs(DEG*2) for Deg "+" Top+(DEG*2) } }); $(document).mouseup(function() { dragStatus = 2; }); });? Thanks for any help fixing this. Mainly an issue with the math, just don't know how I can fix this.

  • Merging $.get and $.ready

    - by cwolves
    Put simply I have an ajax call that sometimes completes before the page is loaded, so I tried wrapping the callback in $( fn ), but the callback doesn't fire if the page is loaded... Anyone have a good solution to this? $.get( '/foo.json', function( data ){ $( function(){ // won't get here if page ready beats the ajax call // process data $( '.someDiv' ).append( someData ); } ); } ); And yes, I know that if I flipped the order of those it would always work, but then my ajax calls would be needlessly deferred until the document is ready.

  • How to get four following text inputs after each checkbox?

    - by Richard Knop
    I am traversing checkboxes like this: $('.day').each(function() { // here I need to get the following 4 text inputs in the HTML // and set some attributes on them }); After every checkbox there are four text input fields (there are also some div, span tags for CSS around them). So inside the loop above I need to get four text input fields that follow the checkbox in the HTML source so I can set some attributes on them. How would I go about that?

  • .find replacing content inside html tags

    - by Woz
    I want to sanitize html tags from my wysiwyg. I want to replace certain tags with another. This almost works only the replaceWith() is also removing the content from within the tags. I dont want to do this. I just want to replace the tags. Here is what I have so far. Text for Testing: This<div>is</div><div>a test</div><div>to clean&nbsp;</div><div>some tags</div><div><br></div> Expected Result: This<p>is</p><p>a test</p><p>to clean</p><p>some tags</p><p><br></p> Actual Result: This<p></p><p></p><p></p><p></p><p></p> This is the code I am using to find and replace var thebad = ["h1","h2","h3","h4","h5","h6","div"]; var thegood = ["","","","","","","<p>"]; for(var i = 0; i < thebad.length; i++){ $('.content').contents().find('body').find(thebad[i]).replaceWith(thegood[i]); } I need to figure out how to keep the text inside the html tags when i replace them. Thanks in advance

  • Prevent keypress whilst shift key is held

    - by deifwud
    I'm trying to prevent certain keys from being entered into an input box, but only if that particular key is pressed whilst the shift key is held: $('selector').keydown(function(e) { console.log(e.shiftKey); if (e.shiftKey && e.which == 51) { e.preventDefault(); alert('Disallowed'); } }); The alert fires but the character still appears in the text box. If I remove e.shiftKey from the if statement and press the key (without shift held), the alert fires and the character does not appear in the text box. I've tried searching around for an explanation as to why this happens but to no avail, any help would be greatly appreciated! edit Removing the alert seems to fix the problem (which seems bizarre), I'd really love to know why it behaves in this way though, it doesn't seem to make any sense. Thanks

  • How to add attributes to a HTML element in a valid way?

    - by Click Upvote
    I want to be able to add an attribute to a HTML element to be able to identify what its referring to. E.g if I have a list of names and a checkbox next to each name, like this: <div id="users"> Bob smith <input type=checkbox /> </div> And when a checkbox is clicked and the event handler function for it is called, I want to be able to identify which user was selected/unselected. Ideally I'm looking for something like this: <input type=checkbox data-userId = "xxx" /> Then when its clicked: function handleClick() { var userId = $(this).attr('data-userId'); } However I'm looking to do this in a way that won't break my HTML validation, and would still be valid HTML and work in all browsers. Any suggestions?

  • AJAX Closures and targeting 'this'

    - by Nick Lowman
    In the code example below the success callback function logs 'input#04.update' four times rather than each individual input, which makes sense seeing how closures work but how would I go about targeting each individual input using this. <input type="text" name="" id="01" class="update"> <input type="text" name="" id="02" class="update"> <input type="text" name="" id="03" class="update"> <input type="text" name="" id="04" class="update"> function updateFields(){ $('input.update').each(function(){ $this = $(this); $.ajax({ data: 'id=' + this.id, success: function(resp){ console.log($this); $this.val(resp) } }); }); }

  • Disable form submission via Enter key on only _some fields

    - by justSteve
    I want to retain the conventional 'form submits when i press Enter' behavior because users are familiar with. But by reflex, they often hit enter when they finish with a text input box - but before they are actually done with the complete form. I'd like to hijack the Enter key only when then focus is on a certain class of input. Looking Related Questions this looks like what I'm looking for: if (document.addEventListener) { document.getElementById('strip').addEventListener('keypress',HandleKeyPress,false); } else { document.getElementById('strip').onkeypress = HandleKeyPress; } but the if (document.addEventListener) { is unfamiliar.

  • Bind event to AJAX populated list items

    - by AnPel
    I have an unordered list with no list items. I get some information from the user, I run it through my database using AJAX and the servers sends back a JSON object response. Then I append each list item I want to display to the list using something like $('blabla').append('<li>information</li>') My question is, since the li elements were not there at the time the DOM was ready, how can I bind a click event to them? Here is my full code: $(function(){ var timer; $('#f').keyup(function(){ clearTimeout(timer); timer = setTimeout(getSuggestions, 400); }); }) function getSuggestions(){ var a = $('#f')[0].value.length; if( a < 3){ if(a == 0){ $('#ajaxerror').hide(300,function(){ $('#loading').hide(300,function(){ $('#suggest').hide(300) }) }) } return; } $('#loading').slideDown(200,function(){ $.ajax({ url: '/models/AJAX/suggest.php', dataType: 'json', data: {'data' : $('#f')[0].value }, success: function(response){ $('#ajaxerror').hide(0,function(){ $('#loading').hide(100,function(){ $('#suggest ul li').remove(); for(var b = 0; b < ( response.rows * 3); b = b + 3){ $('#suggest ul').append('<li>'+response[b]+' '+response[b+1]+' '+response[b+2]+'</li>') // MISSING SOME CODE HERE TO BIND CLICK EVENT TO NEWLY CREATED LI } $('#suggest').show(300) }) }) }, error: function(){ $('#suggest').hide(0,function(){ $('#loading').slideUp(100,function(){ $('#ajaxerror').show(300) }) }) } }) }) }

  • Dynamically choosing css property in animation

    - by paddywhack
    Hi, It seems a straightforward thing but I'm not having much success. I'm just implementing a simple animation moving a div left or up using animate() but I would like to be able to set the "top" and "left" css properties dynamically. I would like to use the same function rather than have to have two, one for "left" and one for "top". Here's some code which gives the idea. function test($element){ $element.click(function(){ var cssProperty; var direction = "left"; var moveTo = "100px"; if (direction === "top") { cssProperty = "top"; } else { cssProperty = "left"; } /*Using variable as CSS property - This doesn't work */ $(this).animate({ cssProperty: moveTo }, 1000); /*Using variable as the CSS Values - This does */ $(this).animate({ left: moveTo }, 1000); }); } Variables works on the css value side but not on the css selector side. Anyone have any suggestions? Thanks

  • Same function on multiple div classes doesn't work

    - by Sebass van Boxel
    I'm doing something terribly wrong and just can't find the solution for it. Situation: I've got a number of products with a number of quotes per product. Those quote automatically scroll in a div. If the scroll reaches the last quote is scroll back to the first one. What works: The function basically works when it's applied on 1 div, but when applied on multiple div it doesn't scroll back to the first one or keeps scrolling endlessly. This is the function i've written for this: function quoteSlide(divname){ $total = ($(divname+" > div").size()) $width = $total * 160; $(divname).css('width', ($width)); console.log ($totalleft *-1); if ($width - 160 > $totalleft *-1){ $currentleft = $(divname).css('left'); $step = -160; $totalleft = parseInt($currentleft)+$step; }else{ $totalleft = 0; } $(divname).animate(     { left: $totalleft }, // what we are animating     'slow', // how fast we are animating     'swing', // the type of easing     function() { // the callback }); } It's being executed by something like: quoteSlide('#quotecontainer_1'); in combination with a setInterval so it keeps scrolling automatically. This is the jsFiddle where it goes wrong (So applied on more than 1 div) http://jsfiddle.net/FsrbZ/. This is the jsFiddle where everything goes okay. (applied on 1 div) When changing the following: quoteSlide('#quotecontainer_1'); quoteSlide('#quotecontainer_2'); setInterval(function() { quoteSlide('#quotecontainer_1'); quoteSlide('#quotecontainer_2'); }, 3400);? to quoteSlide('#quotecontainer_1'); setInterval(function() { quoteSlide('#quotecontainer_1'); }, 3400);? it does work... but only on 1 quotecontainer.

  • How come $(this) is undefined after ajax call

    - by JohnnyQ
    I am doing an ajax request when an anchor tag is clicked with an ID set to href. Btw, this anchor tag is dynamically created. <a href="983" class="commentDeleteLink">delete</a> When the anchor tag is clicked the following code is executed: $('.commentDeleteLink').live('click', function(event) { event.preventDefault(); var result = confirm('Proceed?'); if ( result ) { $.ajax({ url: window.config.AJAX_REQUEST, type: "POST", data: { action : 'DELCOMMENT', comment : $('#commentText').val(), comment_id : $(this).attr('href') }, success: function(result) { alert($(this).attr('href')); //$(this).fadeOut(slow); } }); } }); When I tried to display $(this).attr('href') it says it's "undefined". What I really want to do is fadeOut the anchor tag but when I investigated the value of $(this) it is "undefined". What could be wrong with the snippet above?
