JS window.onload Usage Vs Document

由 徘徊边缘 提交于 2019-12-06 07:03:12
问题 window.onload from my reading sounds like it is loosely interchangeable with document.onload but my experience has shown this is incorrect. I've inherited a JS script and I'm not sure how to correct it. I want the JS to execute once the DOM has loaded, not once all resources have been loaded. How can I do this? Currently I have: window.onload = initDropMenu; I've tried: document.onload = initDropMenu; which just results in the menu not loading. I've also tried removing the line altogether

Using jQuery / javascript How to check if JS file ( SP.JS) is already called in a page?

由 限于喜欢 提交于 2019-12-06 04:33:16
I want to check if a particular JS file is already loaded in document.ready. Something like this: if(file already called/loaded) { // my code } else {//some other code} The JS File is not any plugin. Its basically a JS file related to SharePoint like Sp.JS. We just know the file name. [Update - Added the code ] I have added the below code and it throws an error in console : SP.Runtime.js is already loaded. If I remove the loading of SP.Runtime.js my code doesnt work in some pages where Runtime.Js is not loaded by default. $(document).ready(function() { var scriptbase = _spPageContextInfo

Difference between $(document).ready and $(document).on('pageinit')

问题 I'm using jquery mobile and I'd like to reproduce this code: $(document).ready(function () { $.mobile.loading('show'); }); it shows the spinner until I decide to hide it using in other functions $.mobile.loading( 'hide' ); Now I see that document.ready() is deprecated in jquery mobile 1.2, so they suggest to replace it with $(document).on('pageinit') But If I replace my code with the suggested one the spinner autohide... why? This is the new code: $(document).on('pageinit',function(){ $

Difference between $(callback) and $(document).ready(function)?

On the jQuery site, the description for $(callback) was that it behaves the same as $(document).ready(function) but then the examples showed some differences between the two syntaxes. So I was wondering, does anyone know exactly what the differences between the two are? There are no differences, and the docs don't show any difference: All three of the following syntaxes are equivalent: $(document).ready(handler) $().ready(handler) (this is not recommended) $(handler) Straight from: http://api.jquery.com/ready/ I think you are confused by the example showing jQuery(function($){ ... }); Which is

head.ready() vs. $(document).ready

由 筅森魡賤 提交于 2019-12-05 16:49:01
Recently discovered the head.js library and boy am I happy with it, although I'm still a bit confused about one thing. From headjs.com: The “DOM ready” event such as $(document).ready() is already fired when the scripts arrive. If the loaded scripts depend on that event make sure your library can handle this. jQuery 1.4+ works. With this in mind, what is the best way to set up a page that uses jQuery if the code within $(document).ready() depend of the external scripts loaded with head.js? Can we just lose the $(document).ready() call all together and still successfully set up things like

Running a function just before $(document).ready() triggers

由 馋奶兔 提交于 2019-12-05 15:30:23
问题 I've attached multiple functions in multiple files to $(document).ready and would like to attach a single function to happen before them as either the first that $(document).ready handles or to independently trigger before the $(document).ready handler. Is there any way to handle the order of functions that jQuery triggers internally as part of jQuery.fn.ready or to hook in a function that calls just before jQuery.fn.ready. Is editing jQuery.fn.ready in a 3rd party script safe to do or will

How can I run a fallback copy of jQuery after the DOM is loaded?

问题 The following are the first lines of code in a <script> tag just above the closing body tag in my document (it specifies that a locally-served copy of jQuery is run in the event that Google's CDN fails): if(!window.jQuery){ var script = document.createElement('script'); script.type = 'text/javascript'; script.src = '/js/jquery.js'; var scriptHook = document.getElementsByTagName('script')[0]; scriptHook.parentNode.insertBefore(script, scriptHook); } jQuery(document).ready(function($){ // page

Another questionable jQuery Quiz answer at W3Schools

There is a jQuery quiz posted on the W3Schools site here... http://www.w3schools.com/quiztest/quiztest.asp?qtest=jQuery Question #16 is as follows, Which jQuery function is used to prevent code from running, before the document is finished loading? A. $(document).load() B. $(document).ready() C. $(body).onload() I got it wrong by picking answer A. (their official answer is B.) I answered it, thinking that I knew the following, document.load fires after everything on the page loads including all images document.ready fires only after the DOM is loaded (not necessarily all the images have been
