• Why does this vertical-align:middle fails in Jquery mobile

  - by SJ GJ

  Am trying to middle a set of icons to the middle of screen, below is the code: <div data-role="content" class="ui-content ui-body-a" style="vertical-align: middle" data-theme="a"> <fieldset class="ui-grid-a icon-set" style="vertical-align: middle" data-theme="b"> <div class="ui-block-a center" style="vertical-align: middle"> <a href="test"> <div> <img src="css/images/test5.png" style="width: 80px;height: 80px"/> </div> <div> Login </div> </a> </div> <div class="ui-block-b center"> <a href="#settings" data-transition='slide'> <div> <img src="css/images/test4.png" style="width: 80px;height: 80px"/></div> <div>Settings</div> </a> </div> <div class="ui-block-a center"> <a href="test"> <div> <img src="css/images/test2.png" style="width: 80px;height: 80px"/></div> <div>Aboutus</div> </a> </div> <div class="ui-block-b center"> <a href="test"> <div> <img src="css/images/test1.png" style="width: 80px;height: 80px"/></div> <div>Contact Us</div> </a> </div> </fieldset> </div>

• jQuery animate element reveal - bottom to top

  - by Jon Hadley

  I'm trying to animate a horizontal lists appearance. It's a top navigation bar. The following works pretty well, but it animates in from the top (of, I assume, the ul) to the bottom. How would animate bottom, up? $("#topnavigation li").css({height:'0'}); // 'hide' it first $("#topnavigation li", this).stop().animate({height:'23px'},{queue:false,duration:1000});

• JQuery transition animation

  - by kk-dev11

  This program randomly selects two employees from a json-object Employees array, winnerPos is already defined. For better user experience I programmed these functions to change pictures one by one. The animation stops when the randomly selected person is shown on the screen. The slideThrough function will be triggered when the start button is pressed. function slideThrough() { counter = 0; start = true; clearInterval(picInterval); picInterval = setInterval(function () { changePicture(); }, 500); } function changePicture() { if (start) { if (counter > winnerPos) { setWinner(); start = false; killInterval(); } else { var employee = Employees[counter]; winnerPic.fadeOut(200, function () { this.src = 'img/' + employee.image; winnerName.html(employee.name); $(this).fadeIn(300); }); counter++; } } } The problem is the animation doesn't work smoothly. At first it works, but not perfect. The second time the transition happens in an irregular way, i.e. different speed and fadeIn/fadeOut differs from picture to picture. Could anyone help me to fine-tune the transition?

• jquery switch element classes

  - by Sobakinet

  Please take a look here: http://jsfiddle.net/ZUd27/7/ What I need: There are several elements. One of them is active and visible. If I hover over any inactive element, it becomes visible and active. The previously active element becomes inactive. On mouseout, nothing happens - the last hovered element stays active. My problems: The first active element always stays active (in DOM?). It becomes invisible, but on next mouseover nothing happens. Other elements don't behave as they should. If one of them is active, on next mousein it becomes invisible. thx

  - by Tony_M

I need to call function changePropertyDropdown() only whith .trigger(), and changePropertyDropdown() + hideCart() on change event. How can i do this ?

• JQuery not working in IE7/8

  - by user1665283

  I have been given the following code to implement: <script type="text/javascript"> $(document).ready(function(){ $('.hotspots a').bind('mouseover click', function() { $this = $(this); if($('.hotspot-target').data('hotspot')!=$this.attr('href')) { $('.hotspot-target').data('hotspot', $this.attr('href')); $('.hotspot-target').fadeOut(100, function() { $('.hotspot-target').css({backgroundImage: 'url('+$this.attr('href')+')'}); $('.hotspot-target .detail').hide(); $('.hotspot-target .detail.'+$this.attr('class')).show(); $('.hotspot-target').fadeIn(100); }); } return false; }) }); </script> It works fine in FF and Chrome with no errors in the console. I also can't see any errors in the IE debugger, though I'm not so used to how that works. Is there anything obviously wrong with the above code? It's placed at the end of the page

• Passing data to a jQuery click() function

  - by jakenoble

  Hi I have a simple span like so <span class="action removeAction">Remove</span> This span is within a table, each row has a remove span. And then I call a URL using AJAX when that span is clicked. The AJAX event needs to know the ID of the object for that row? What is the best way of getting that ID into the click function? I thought I could do something like this <span class="action removeAction" id="1">Remove</span> But an ID should not start with a number? Right? Then I thought I could do <span class="action removeAction" id="my1">Remove</span> Then just strip the 'my' part from the ID, but that just seems Yuk! Below is my click event and where my AJAX event is. <script type="text/javascript" language="text/javascript"> $(document).ready(function() { $(".removeAction").click(function() { //AJAX here that needs to know the ID } }); </script> I am sure there is a nice way of doing this? Thanks. Jake.

  I have an ajax call in the head section of my index.html $.ajax({ method: 'get', url : 'php/getRecord.php?color=red', dataType: "json", success: function (data) { alert(data); } }); For some reason, that alert never gets called. Am I doing something wrong? The PHP file does give me data when testing it directly.

• scrollTop with jQuery

  - by Narcís

  I want a foot to be at the bottom of the page. But when the user makes the window smaller, the two divs come together, it would be better that begins the scroll and hides the foot. I don't know if I explain? I have the code life here: http://jsfiddle.net/mdAsn/ $(function(){ $(document).scroll(function(){ var topDistance = $('#foot').scrollTop(); if(topDistance >= 420){ $('#foot').css({position: 'absolute',bottom:'10px'}); } else{ $('#foot').css({position: 'absolute',top:'410px'}); } }); })

• Jquery JSON .each() doesnt work in Google Chrome

  - by Sheriffen

  I have a really simple chat application on a site which works pretty good. It requests by ajax like this: $.ajax({ url: "fetch/"+CHAT_SESSION_ID+"/"+LAST_MESSAGE_ID, dataType: "json", cache: false, success: function(data) { if (data.session_active == 0) { //If other chatter ended session alert("Session Ended"); } else { $.each(data.messages, function(i,msg){ alert(msg.message.Body); )}; } } }); and gets a json response that lookes like this: { "session_active": "1", "messages": [ {"message": {"MsgID": "100", "UserID": "1", "Body": "heyy"}}, ]} It works really well in at least FF and Saf but in Chrome it never gets past the .each! This is driving me nuts, have tried everything I've come across online for days but I can't seem to get it right. Please someone help! I can provide testserver if someone wants to firebug it themselves ;)

• JQUERY: Multiplying input elements select box and radio boxes and hidden inputs

  - by Andrew Tan

  Evening, I'm tyring to multiply different input elements but for some reason it's giving me a NAND error. As the user selects, check or modify the values of any element. This should change the total amount. http://jsfiddle.net/aQ5K8/ <select name="select"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> </select> <input name="radio" type="radio" id="radio" value="10" tvalue="100" /> <input name="radio" type="radio" id="radio" value="20" tvalue="200" /> <label id="Total"></label> Also if you take a look at the jsfiddle code i have tvalue=100 and the other is =200 as a custom attributes, how would I access that instead of accessing the regular html value. Thank you.

• Adding an additional click event to every element (JavaScript / jQuery)

  - by Gausie

  I'm developing a touchscreen application that, aside from everything else, records the amount of times the screen is used so that the user can be reminded to clean the screen after a predefined number of clicks. I've got the click functions written nicely, all I need now is make sure the function is called on a click. I imagine $('*').click(function() { //do something }); would accomplish my goal, but is that the best way? Also, would that overwrite other click functions assigned to the elements?

• Prevent event from parent element to child element in jquery

  - by sonam

  I have binded event as below: $(document).delegate('.budget', 'click', function(e){ if ($(this).hasClass('collapsed')) { $(this).removeClass('collapsed'); $(this).addClass('expanded'); } else if ($(this).hasClass('expanded')) { $(this).removeClass('expanded'); $(this).addClass('collapsed'); } }); Basically this toggles between expand and collapse. I have another event binded as below: $('[id^="tree"]').delegate('.collapsed', 'click', function(e){ var elementId = $(this).attr('id'); hideChildElement(elementId); }); The elements binded by the second event binding are parents of elements binded by first event binding. What happens is that on clicking on the element from the first binding event method also triggers the event binded by second event binding. I want to prevent any events from binding from second event binding to 1st event binding method. If element A is binded to click event from first event binding and B is binded to second event binding (A is inside B or A is child of B), I dont want any event of B to propagate to A. Note I tried e.stopImmediatePropagation(); but did not worked

• jQuery .die isnt killing an attached event?

  - by adam

  Hi I've just started experimenting with .live and .die and having some great results but one thing isn't working. I've been tinkering with firebugs console to try out my written code live to see if i can figure out the reason why .die isn't killing off an attached event. First if i do this //attach ajax submission $('a[href$=edit]').live("click", function(event) { $.get($(this).attr("href"), null, null); return false; }); Then as expected when I click on a link the ajax fires off and my server side code injects a form for inline editing. But sometimes I want to disable this behaviour and also make the link unclickable so I do the following //unbind ajax form creation when we click on a link, then disable its semantic behaviour $('a[href$=edit]').die("click").click( function(){ return false; } ); which works but if then try to remove this and restore that ajax goodness with the code below it doesn't work, Instead the link remains unclickable. I cant figure out why? Can anyone help? //remove any previous events from the links $('a[href$=edit]').die(); //attach ajax submission $('a[href$=edit]').live("click", function(event) { $.get($(this).attr("href"), null, null); return false; });

• jQuery Syntax Question, pretty easy I think..

  - by Fuego DeBassi

  Hi all, question: <script type="text/javascript"> $(document).ready(function() { $(".module .caption").hide(); $(".module").hover(function() { $(this).find(".caption").slideDown(); },function() { $(this).find(".caption").slideUp(); }); }); </script> This snippet works great for my purposes, the only caveat is that I need the .module hover function to simultaneously add a class of "under" to all other ".caption"'s that are not $this, and then remove them when the hover ends. So basically I don't want the "module" that is hovered to get the class, I want it to do exactly what I am showing here...sliding .caption up and down on end hover, I just want all other ".caption"s to get the under class when any ".module" is hovered. Just hitting a dead end with what I have been trying, want to do it in the same function. Any ideas?

• Making JQuery horizontal accordion close on click

  - by user310404

  Example: http://vincent-massaro.com/map/ Currently, the script allows you to click on a piece of the accordion to open it, but it is set to close on mouseleave. When I set the mouseleave to .click, it gets confused and doesn't know what state it is in. The code controlling this is below, and the full script is in haccordion.js linked in the page source. If someone could help me modify this script, I would be very grateful! Thanks in advance. $target.click(function(){ haccordion.expandli(config.accordionid, this) config.$lastexpanded=$(this) }) if (config.collapsecurrent){ //if previous content should be contracted when expanding current $target.mouseleave(function(){ $(this).stop().animate({width:config.paneldimensions.peekw}, config.speed) }) }

• jquery next() outside of div

  Hi, I'm trying to use next() to toggle a div. The problem is that the "trigger" is in a different div than the one I want to toggle. An example that works: $("span.trigger").click(function(){ $(this).next("div.task_description").slideToggle("fast"); }); <span class="trigger">The trigger</span> <div class="task_description "> some content </div> But the way I need the html setup is: <div> <span class="trigger">The trigger</span> </div> <div class="task_description "> some content </div> That doesn't work... any suggestions?
