• Animating the <li> removal in jQuery

  - by Marco

  Hi guys, i'm adding and removing <li> elements with jQuery, that are shown horizontally with the following style: #my_ul { list-style: none; } #my_ul li { float: left; margin: 0px 15px; } For example, if i add four <li> to an <ul> and then i decide to remove the second one, after it has been removed the other two <li> elements on the right immediately move to the left. What i'd like to do is to animate this behaviour, with the remaining <li> elements that softly moves to the left. Any tips? Thanks

• passing a variable to a ajax request Jquery

  - by user304735

  Hello, I am trying to pass a variable to an ajax request via jquery. I have a triggered event that defines the variable. I want to do this so that I can have one ajax request handle multiple urls. I have alerted the url and it come back fine, but when I plug it into the URL slot of a $.ajax request my targeted content does not load. Here is my code. $(document).ready(function(){ $('a').live('click', function(){ var link = $(this).attr("href"); $.ajax({ url: link, success: function(html){ $('#load').html(html) } }); }); }); this has been a real headache and I feel I am just misusing something. Please help.

• jQuery Toggle with multiple unique DIVs?

  - by tony noriega

  I am using jQuery toggle with a link and a div. I will eventually have approx. 50 divs i want to toggle, and instead of creating a new function for each one, is there a way i can create a class and have it read unique ID's for each div? (if that makes sense) For instance, i will have A1, A2, A3, B1, B2, B3..e.tc.. $(document).ready(function() { $('#slickbox').hide(); $('a#slick-toggleA1').click(function() { $('#A1').toggle(300); return false; }); });

• using document.createDocumentFragment() child dom elements that contain jQuery.data

  - by taber

  I want to use document.createDocumentFragment() to create an optimized collection of HTML elements that contain ".data" coming from jQuery (v 1.4.2), but I'm kind of stuck on how to get the data to surface from the HTML elements. Here's my code: var genres_html = document.createDocumentFragment(); $(xmlData).find('genres').each(function(i, node) { var genre = document.createElement('a'); $(genre).addClass('button') .attr('href', 'javascript:void(0)') .html( $(node).find('genreName:first').text() ) .data('genreData', { id: $(node).find('genreID:first').text() }); genres_html.appendChild( genre.cloneNode(true) ); }); $('#list').html(genres_html); // error: $('#list a:first').data('genreData') is null alert($('#list a:first').data('genreData').id); What am I doing wrong here? I suspect it's probably something with .cloneNode() not carrying over the data when the element is appended to the documentFragment. Sometimes there are tons of rows so I want to keep things pretty optimized, speed-wise. Thanks!

• jQuery to PHP: no input... kinda

  - by Seva Alekseyev

  Hi all, I'm using jQuery to post HTTP requests to my PHP page (Apache/Linux, if that matters). I carefully validate on the client so that empty requests are not sent. However on occasions, I'd get an empty request like this: - $_POST collection empty ($_GET collection also empty); - Content-Length is nonzero (a number below 100, consistent with a valid POST from my script) - Content-Type properly application/x-www-form-urlencoded - reading from php://input yields an empty string It's as if $_POST is somehow eaten on the way. I checked the code very carefully - I don't do anything to the contents of $_POST. Any ideas, please?

• Using "class/object" MooTools-style events in jQuery

  - by Infinity

  One of the nice things about MooTools, is that it lets you easily assign/fire events to objects, for example: var playerSingleton = new (new Class({ Implements: [Events], initialize: function() {}, setVolume: function() { // do some stuff.. this.fireEvent('volumeChanged') } })); // Somewhere else... playerSingleton.addEvent('volumeChanged', function() { // do something when volume changes }); playerSingleton.setVolume(75); // bam our event fires. How would something like this be done with jQuery? I know there's .bind and .trigger, but it seems like the only way to do this is to bind/fire events to the window object: $(window).bind('volumeChanged', fn); Is there anything better than this, more like the MooTools approach? Thanks!

• jQuery UI sortable issue with helper Y offset value being same as scroll offset on FireFox only

  - by James

  I have a problem with a jQuery UI 1.7.2 sortable list in Firefox, IE7-8 work fine. When I'm scrolled down a bit, the helper element seems to have an offset of the same height that I'm scrolled down from the mouse pointer which makes it impossible to see which item you originally started dragging. How do I fix this or work around the issue? If there is no fix what is a really good alternative drag-able plugin? Here are my initialization parameters for the sortable. $("#sortable").sortable( {placeholder: 'ui-state-highlight' } ); $("#sortable").disableSelection();

• Seeking to zoom in on an image, slowly, on page load, using Jquery

  - by Heath Waller

  Hello, I am looking to give the impression of zooming in from a large image to a detailed area of that image, over time, when the page loads - using javascript (jquery, preferably). I have been given the following flash site as a reference (action happens just after title fades in): http://www.delicatessennyc.com/ Not sure if this is even possible. I know I could switch out the large image for a smaller one - but my boss is hellbent of achieving this flash-type action using javascript. Please note, I've searched the plugins and I've not found anything like what I'm looking for. And I'm so new to this type of coding that cobbling it together from scratch seems daunting. Thank you all so much.

• jquery issue, disable on mouseenter queue

  - by jason

  When you mouseenter .li_group class it does a slide down effect on 1 single <li> tag, everything goes smoothly, but during the delay if you take your mouse off and on .li_group it "queues" the effect and slides the li down, delay, slides it down again etc etc... I have tried every way i can think of, even stop(); but it still does it... the reason i use mouseenter instead of hover, is because it works better for ul / li list $(".li_group").live('mouseenter',function(){ var id = "#ec1"; $(id).slideDown(); }).live('mouseleave',function(){ if (jQuery.support.cssFloat==true || getInternetExplorerVersion() > 7) { //ie < 8 endless up/down on close var id = "#ec1"; $(id).delay(5000).slideUp('fast'); } });

• ASP.NET Repeater Causing JQuery Image Slider

  - by Bry4n

  I have a jquery Image slider in a content page that worked fine. Once I converted it into a asp repeater the first image of the repeater would display twice, then run normally. Any idea on why the repeater is causing this? I think I discovered that the first image link <ItemTemplate> <a href='<%#Eval("Url")%>'> <img src='<%#Eval("Image")%>' alt="Spring Break 2011" rel='<h3><%#Eval("Title")%></h3><%#Eval("Caption")%>'/></a> </ItemTemplate> I have to place class="show" in the first item only. Does anyone know how to implement this during the first time it goes through. Hmm

Here is ths custom method... $.validator.addMethod("uniqueUserName", function(value, element) { $.ajax({ type: "POST", url: "php/get_save_status.php", data: "checkUsername="+value, dataType:"html", success: function(msg) { // if the user exists, it returns a string "true" if(msg == "true") return false; // already exists return true; // username is free to use } })}, "Username is Already Taken"); And here is the validate code... username: { required: true, uniqueUserName: true }, Is there a specific way i am supposed to return the message from php.

  I am using jQuery to hide a div on my page: $(document).ready(function(){ $('#message').hide(); When a certain part of the page scrolls into view the div shows using $(window).scroll(function() { var top = 0; top = $(window).scrollTop(); if((top >= 1000) && (top < 2000)){ $('#message').fadeIn('slow'); } } I want to add a close button to this as follows $('a#message-hide').click(function() { $('#message').hide('fast'); return false; All good so far but the part I cannot figure out is how to then STOP the div re-appearing when the user scrolls back to the trigger position on the page...?

• jQuery event to trigger action when a div is made visible

  - by frankadelic

  I'm using jQuery in my site and I would like to trigger certain actions when a certain div is made visible. Is it possible to attach some sort of "isvisible" event handler to arbitrary divs and have certain code run when they the div is made visible? I would like something like the following pseudocode: $(function() { $('#contentDiv').isvisible(function() { alert("do something"); }); }); The alert("do something") code should not fire until the contentDiv is actually made visible. Thanks.

• JQuery Autocomplete only suggesting first row

  - by Chris McCall

  I'm doing research using JQuery's Autocomplete plugin and Google Maps' API. What I have so far is located here. I'm using Asp.net MVC to generate the list of potential address matches (limited to US addresses only) and presenting them as a pipe-delimeted list to Autocomplete, which is supposed to be .spliting them up and suggesting them to the user. The problem I'm having (besides a stubborn IE-only javascript error, which I'll break into another question), is that only the first result is suggested. This page clearly shows two results, yet typing "3118" into the textbox produces only the Galax Dr result. How can I get Automplete to produce both results?

• PHP / jQuery page change transition

  - by Tim

  Hey all Basically I want to replicate the page changing effect found here, at http://timvandamme.com/ But instead of using #values I want to use PHP includes, mainly because I want the site to be as uber-seo-friendly as possible... but still have this nice effect. So is there a way of doing this? I have a main index file which includes other php files in the centre using the usual 'GET' method, so my pages look like: "index.php?page=about" In my jQuery code I want to have a declaration where if I click the navigation, the content scrolls up, then once the relevant PHP file has loaded, have the content scroll back down and show the new page content (whilst also of navigated to the new page in the address bar, so if the user clicks the back button in their browser, they return to the previous page). I know how to code the scrolling bits, it's just literally the ajax loading includes / page navigation parts I'm struggling to work out :\ Any help would be MUCH appreciated!!! Thanks in advance.

• Convert json to a string using jquery

  - by becomingGuru

  I have a nested json. I want to post it as a form input value. But, seems like jquery puts "Object object" string into the value. It seems easier to pass around the string and convert into the native form I need, than dealing with json as I don't need to change anything once it is generated. What is the simplest way to convert a json var json = { "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ], "newSubscription": false, "companyName": null }; into its string form? var json = '{ "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ], "newSubscription": false, "companyName": null }' Following doesn't do what I need: Json.stringify()

• Extract form variable in AJAX response using jquery

  All, I have a Jquery ajax request calling out a URL. The ajax response I receive is an HTML form with one hidden variable in it.

• Shortest way of attaching multiple DOM elements to one event handler using Jquery?

  - by Camsoft

  I need to attach a single event handler to multiple DOM elements using jQuery. I'm currently achieving this using jQuery's each() method. See below: $([elm1, elm2, elm3]).each(function() { this.click(eventHandler); }); I was wondering if there is a way to do this without using the each method and closure. I thought I would be able to do something like: $(elm1, elm2, elm3).click(eventHandler); This kind of statement works using Prototype.js but not in jQuery.The reason I ask the question is because after using both Prototype.js and jQuery I have found that jQuery requires simpler statements to achieve the same tasks in almost every area so I assume there must be a better way of doing this?

While the html() method properly evaluates the inline JS code, it doesn't download and evaluate the external JS file "myfile.js". Any tip for this issue?

• jQuery iframe overlay with flash closing issue

  - by Ryan Max

  Hello, I have a site that has a jQuery overlay, which contains an iframe, which pulls in another site that has flash in it. One of the buttons in the flash has editable parameters in xml, and I can change where the link points to. I want this button to close the overlay, but I can't quite figure out how to get it to work. I have tried the following: closeSection(); and parent.closeSection(); and window.parent.closeSection(); None of which work. Though the last two come close. They seem to close the flash, as the iframe just goes blank. Can anyone steer me in the right direction?
