Caching problem with asynchronous javascript loading with onload event

由 耗尽温柔 提交于 2019-12-07 13:43:01
问题 I am currently trying to load some js files asynchronously, so that they are not able to block the rest of the website. I mainly followed the descriptions found here: Asynchronous Javascript In terms of the non blocking loading of the javascript file this works great, but i got now the problem that the javascript file is cached and stays cached even if i change the content (also doing shift-reload does not help anything). My current code of loading the script looks like the following:

dynamically change onload for an iframe

问题 I have a page containing a couple of <iframe> tags. I want to change their onload actions dynamically. I have the following code that works fine in FF, Safari, Chrome, Opera, but IE (8) refuses to comply. document.getElementById('myiframe').onload = function() { return function() { file_onLoad(data); } }(); I've been using something similar for setting the onchange of an <input> element and this works well in all the browsers I've tested, including IE. document.getElementById('myinput')

addLoadEvent is not helping with onload conflict

由 与世无争的帅哥 提交于 2019-12-07 13:08:46
问题 I'm using the popular addLoadEvent as follows for all my JS loading: function addLoadEvent(func) { var oldonload = window.onload; if (typeof window.onload != 'function') { window.onload = func; } else { window.onload = function() { if (oldonload) { oldonload(); } func(); } } } addLoadEvent( locationToggle ); addLoadEvent( step1 ); addLoadEvent( step2 ); addLoadEvent( step3 ); addLoadEvent( getCounties ); addLoadEvent( mapSelection); Everything I've read suggests this is a fairly bullet proof

Run ResponsiveVoice speech on page load

问题 This works properly, it speaks the text area on click, but how can I change it to speak onload ? <script src="http://responsivevoice.org/responsivevoice/responsivevoice.js"></script> <script src="http://code.jquery.com/jquery-git2.js"></script> <textarea id="text" cols="45" rows="3"> HHHH</textarea> <select id="voiceselection"></select> <input onclick="responsiveVoice.speak($('#text').val(),$('#voiceselection').val());" type="button" value="Play" /> <br> <button id="isPlaying">Playing:<

What would be a walkaround for JavaScript alerts that are generated in a page's onload() using Selenium?

由 感情迁移 提交于 2019-12-07 12:41:54
问题 I am automating a form page using Selenium RC (C#). After I click 'Submit' button, I get an alert ' Records Edited Successfully! '. The title of this alert box is ' The page at http://www .******.com says: '. But Selenium doesn't see this alert. And I can't work around it. Here is what I've tried: selenium.Click("ctl00_Content_ctl00_btnSubmit"); selenium.WaitForPageToLoad("30000"); Result: I get the following error: " Selenium.SeleniumException : Timed out after 30000ms " Then I tried:

Load external javascript file after onload()

由 倖福魔咒の 提交于 2019-12-07 12:33:48
问题 I use this in the head tag: <script src="js/lightbox.js"></script> Is it possible to remove this off the header and load this file with onload() ? <body onload="...">...</body> Note: This is not a function, it's an external js file with several functions. Thanks! 回答1: <script> function loadJS(src, callback) { var s = document.createElement('script'); s.src = src; s.async = true; s.onreadystatechange = s.onload = function() { var state = s.readyState; if (!callback.done && (!state || /loaded

Has window.onload event already fired

由 ╄→гoц情女王★ 提交于 2019-12-07 01:58:44
问题 I have a small javascript util which may get preloaded, lazy loaded or loaded on demand. When it's initiated it adds some stuff to the DOM. It's low priority and if it's preloaded it can wait for the onload event to fire before running, but if it's lazy loaded it can go ahead and run immediately. Currently It's checking to see if the ID of the footer element exists to determine if it should add an event listener to the window onload event or just run. e.g. if ( document.getElementById("footer

Script onload happens after window onload in JSDOM

由 偶尔善良 提交于 2019-12-06 17:41:28
问题 This is a new question arising from what I learnt in: Is order of script onload and window.onload well defined when the script is a DOM node created dynamically from a loaded script? In the previous question we learnt that when a window is loading scripts, any scripts (the one directly loaded as well as the ones dynamically being loaded by the script) would finish loading first and only after that the window.onload will fire. But JSDOM seems to be behaving differently. Here is the loader.js

Can I check whether an image has already been loaded earlier using Javascript or jQuery?

由 谁说我不能喝 提交于 2019-12-06 14:47:52
问题 Consider the following image appended to the document : <img id="someimage" src="http://www.someimage.jpg"> None of the following will work if the image has already been loaded by the time these functions are called : document.getElementById('someimage').onload = function () { console.log('image just loaded'); }; nor $("#someimage").load(function () { console.log('image just loaded'); }); Is there a way around that ? i.e. a function that will not wait for the image to load but will check

Automatically load an image using javascript

I'm using this code to build a gallery: window.onload=function(){ var image = document.getElementsByClassName('thumbnails')[0].getElementsByTagName('img'); var mainImage = document.getElementById('rr_lrg_img'); [].forEach.call(image,function(x){ x.onmouseover = function(){ mainImage.src = x.src; }; }); } The code loads different thumbnails on the big image when "onmouseover". Now I would like to "preload" the first image from that gallery of thumbnails. I tried using onload with rr_lrg_img.src=document.getElementsByClassName('thumbnails')[0].getElementsByTagName('img')[0].src but then it
