阅读更多关于 how to call a function in polymer after the elements have been created (like ready function in jquery)

问题 I'm trying to write a function, which is related to the DOM, but the problem is , polymer calls the function before the DOM is loaded, and as expected it gives me an undefined error! I was looking for an event like onComplete or anything like this, so that It could read my function after loading the DOM. *** the best example is ready function in Jquery P.S : "ready:" event in polymer doesn't work properly, 回答1: You could do something like this: var domReady = function (func) { if ('complete'

Bind document.ready to a popout window

阅读更多关于 Bind document.ready to a popout window

问题 Due to the manner in which jQuery binds the document.ready event, code that should be simple isn't: var w = window.open(someSameOriginLocation,''); $(w).ready(function () { //alternatively selector could be $(w.document) console.log('popout ready'); }); Problems the callback executes when the parent window is ready, not the child within the callback this is a reference to w.opener.document Is there a reasonably simple, cross-browser way of binding the ready event (or similar) to a different

阅读更多关于 if $(document).not-ready()? How can I check if the page is still loading with Jquery?

问题 I want to call a function only if the document is still loading.. how can I? 回答1: You could check document.readyState or use a simple variable in the global scope: var ready = false; $(document).ready(function () { ready = true; }); 回答2: You could run a function normally in JavaScript and overwrite it within jQuery.ready : function foo() { // … } $(document).ready(function() { foo = function() {}; }); foo(); Now if foo calls itself recursively, it will stop when foo is redefined when the

Is jQuery.ready() valid when used on iframe.contentDocument?

阅读更多关于 Is jQuery.ready() valid when used on iframe.contentDocument?

问题 Simple question (as stated in the title): Is jQuery.ready() valid when used on iframe.contentDocument ? And the complex question: I have to hook a keyup event on an input field in a CMS, hence I have no control over the HTML, only the script. The input is inside an iframe that's nested in another iframe, so there's a top window (the browser window), an iframe (lets call it iframe1) and another iframe inside of that (lets call that one iframe2). The script and jQuery are located in the <head>

BlockUI on DOM Ready

阅读更多关于 BlockUI on DOM Ready

问题 I'm using the jQuery BlockUI plugin to add a loading splash to a page that takes a few seconds to load due to CAML queries. The problem is, the page loads before then the BlockUI displays for a split second and disappears. It seems like JS is executing these in the wrong order and I cannot figure out why. Is there something I can change in the code or is BlockUI just not intended to be used without Ajax? $(document).ready(function() { $.blockUI(); }); $(window).ready(function() { $.unblockUI(

问题 I'm working with a rails 3 app, and I want to use a sortable list. I'm working with the method shown here. My app uses JQuery, and there's a js file included in my app's layout that calls $(document).ready() to set up some visual stuff. That seems to be working fine. However, when I attempt to call $(document).ready() in my view template via content_for :javascript to set up the sortable list, that code never fires. I do have the requisite yield :javascript call in my layout file, and if I

问题 I am wondering which one is the right one to run the js code which calculates the height of vertical menu depending on the window height and sets it on time, not late, not early.

阅读更多关于 jQuery - Object Expected on IE and $(document).ready(function() {});

问题 I have a page ([LINK REMOVED]) that works completely well in FireFox and Chrome, but for some reason I am getting an "Object Expected" error in most, if not all versions of IE. The error occurs on the line $(document).ready(function() { //^ Error occurs here ^ ... } I am using jQuery Tools, which implements jQuery 1.4.2, as well as some additional stuff. I've done some reading around. I've tried to put the ready function at the end of the code, right before the </body> tag - in addition, I've
