A question about the impact may be caused by table's clientWidth/Height behavior change of Chromium
Hi, I'm a contributor of Chromium Project. I made a change of https://chromium-review.googlesource.com/c/chromium/src/+/1763510 which make table's clientWidth/Height match to its offsetWidth/Height. The corresponding issue page for that change is https://bugs.chromium.org/p/chromium/issues/detail?id=978019. In case of Firefox, its already has that behavior, and that is what we intend to introduce by the change above (In perspective of interoperability, it would be good I think). I got a positive
Future of jQuery Real Time Data
Will jQuery every make something for real time data effecting. Am not talking about Ajax request. As Ajax does some short stuff but we have to add time interval to refresh page. Which I think is making too many unnecessary requests to sever. To which we want the data should effect only when the server side is effected in same time in all device. I know there are alternatives but will jQuery bring this kind of change in future or not?
Error in JQuery core
Hello, I am new to JQuery and I downloaded a JQuery core file. When I loaded it into DreamWeaver it told me there is an error in the code. I am hoping you guys can quickly tell me how to fix it! DreamWeaver says that there is a syntax error on the line that says " .catch(function(error){ " Any Ideas? Thank you! jQuery.fn.ready = function( fn ) { readyList .then( fn ) // Wrap jQuery.readyException in a function so that the lookup // happens at the time of error handling instead of callback //
Why was the global flag disabled for cross domain script type $.ajax requests in older versions of jQuery
I'm using jQuery 1.12 and I noticed my global ajax event handlers (`ajaxSend`, `ajaxStart`, etc) weren't running for `$.ajax` requests with `dataType="script"` and `crossDomain=true`. After some investigation I found that in 1.12, jQuery always disabled the global flag on the request if it the dataType is script and it's cross domain! What was the reason for this behavior? Why was it originally added and why was it later removed? Relevant information: From what I can tell, the behavior was originally
JQuery 3.1.1 vs 2.2.4 change in behavior appending rows to a table
The following code: $('<TABLE />').append('<TR><TD>1</TD></TR>').appendTo('BODY'); results in slightly different DOM structures. Under 2.2.4 you get <TABLE><TBODY><TR>... Under 3.1.1 you get <TABLE><TR>... (one has a TBODY and one does not) This causes problems if you later have selectors like #id TBODY TR (to get all the body rows, and no header rows). I've reviewed the jQuery Core 3.0 Upgrade Guide and can't see anything that might be related. So my question is... is this expected behaviour or

document.ready and window.load firing order
Until version 2.2.4, $(document).ready fires before $(window).on("load", function), but with version 3.0.0 $(window).on("load", function) fires first! example: <script> $(document).ready(function(){ alert("ready fired"); }); $(window).on("load",function(){ alert("load fired"); }); </script> Is this a bug or a new feature?

What can actually help in? (Jquery contribution)
Hi, I'm not quite sure if this is the right place to ask and if not then I apologize. But I was wanting to contribute somehow in the Jquery project somehow, so I checked out the contribution page on the site but it sort of left me lost. I have some experience in Jquery and JavaScript but i'm definitely not a whiz at it. I do have some extensive experience in CSS3 and HTML5. So I was wondering where would I be able to contribute (if at all), and if I can't contribute what should I do so that I can?

text() setter method on textnode
Hello, I asked question on stackoverflow but still not sure what could be the reason for this method to not set textnode value. Code sample: $('div').contents().filter(function(){ return this.nodeType === 3; // text node }).text("no change!"); Wouldn't it be an improvement to handle it? What could be the downside/issue? Regards.
Lifetime of $._data
I'm currently working on a tool that examines accessibility issues pertaining to client websites and would like to add jQuery event handling as part of our automatic analysis. One of our rules accounts for having a tabIndex property associated with elements on the page that have an assigned click handler in order to ensure that the elements are also keyboard accessible. Given an HTMLElement, you can use the $._data method to access the event handlers that are associated with said element, which allows

What is the purpose of styles() method in jquery ?
i was just going through the source of jquery css() method and came across the following lines of code : function (name, value) { return access(this, function (elem, name, value) { var styles, len, map = {}, i = 0; if (jQuery.isArray(name)) { styles = getStyles(elem); len = name.length; for (; i < len; i++) { map[name[i]] = jQuery.css(elem, name[i], false, styles); } return map; }
iPhone 6 : jQuery(window).height() .width() dont work one bit.. fix included.
Was testing my seductiveapps.com software on iPhone 6 recently and found that my dialog resizing routines worked but not the background resizing which uses jQuery(window).width() and .height().. Well, it worked, but only after changing orientation on the damn thing once or twice.. This works from the start of the page's lifetime (not mine, found it a few years ago somewhere as browser-independent window width/height detection code) : var height = (window.innerHeight?window.innerHeight:document.documentElement&&document.documentElement.clientHeight?document.documentElement.clientHeight:document.body.clientHeight);
Why does _evalUrl() use async:false?
Why does _evalUrl() use async:false? Would it ever make sense for it to use async: true? Does it affect the user experience at all? My guess is that by doing it synchronously rather than async, you guarantee that javascript files are loaded and executed in order. Is that the reason? A common question when using jQuery is: Why am I seeing this warning: "Synchronous XMLHttpRequest on the main thread... jquery.js?body=1:9628"? The answer is that they are inserting a new <script> tag to the HTML via

What's the rationale of not exposing object's events handlers collections?
What's the rationale of not exposing object's events handlers collections? I've stumbled upon a situation where I wanted to pause all current transitions by registering all transitionend handlers, changing all properties to their current used values, pausing transitions (with forced style refresh afterwards so that it makes effect), running a custom callback and then restoring everything, including handlers. I know this particular case is probably not the most common one but there are cases when
Feature request: remove undelegated events without removing delegated
off() already supports the opposite of this To remove all delegated events from an element without removing non-delegated events, use the special value "**". How about enabling removal of non-delegated events without removing delegated by passing in null or an empty string as the selector? Here is my use case on page load my modal module attaches triggers using a delegated listener (to allow for lazy loading content into the page without having to worry about attaching new listeners) $('body').on('click.modal',

jQuery() vs this.constructor()?
I noticed a few places (init, pushStack, end) in core.js where this.constructor() is used instead of jQuery() which is used throughout the rest of the library. Is there a reason for this? As I understand it this.constructor() is always a reference to jQuery(), is there any situation where that would not be true?
what does “Support: Firefox 18+” mean in jQuery1.9.1 source code?

hey guys, currently $.when() behaves similarly to Q.spread() https://github.com/kriskowal/q#combination when/apply https://github.com/cujojs/when/blob/master/docs/api.md#whenapply that is...the results of multiple promises are passed to the done/fail/progress callbacks via .apply(this, resolvedValues). Most other .all() implementations (Q.all, when.all, RSVP.all) opt to do this via .call(this, resolvedValues), resuting in an single resolvedValues argument passed to the callback rather than as separate
