onload

问题 I'm working with Myfaces 2.0 after a long project using MyFaces 1.1 + Tomahawk + Ajax4JSF. 2.0 is definitely a huge improvement. Although I can't seem to get an onload javascript to work. I stuck this in my head: <script type="text/javascript"> window.onload = function () { var fileDownload = document.getElementById('userManagementForm:fileDownload'); if (fileDownload.value == 'true') { fileDownload.value = false; window.open('Download'); } } </script> But it doesn't execute. I looked a bit

问题 My issue is that sometimes a piece of JavaScript (often Google Analytics) may take a very long time to load, although it's not important to the HTML be ready to be "traversed and manipulated". If I were to use the following code: $(document).ready(function () { $("p").text("The DOM is now loaded and can be manipulated."); }); would this mean that the <p> would not be populated till after something like Google Analytics is loaded? Something like Google Analytics is generally not required on

问题 I can compile DLLs properly using mingw and do the exports/imports stuff. What I am looking for is defining the dll onload function properly as you would in MS VC products. Google didn't turn up anything. Anyone have any ideas or a link to a tutorial? 回答1: Okay, so after some fiddling...it's working. For anyone else that is having issues here it is. My issues weren't related to compiling in instead of loading dynamically. It was a mash-up of a couple of tutorial/question/how-tos that got me

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. I am using document.ready but it is not really helping me with the issue, it is not setting sometimes, I have to reload the page, then it is working, but not on the first load. How to solve this problem? Here is my code: $(document).ready(function(){ var winh = document.body.clientHeight; var footer = document

问题 I've got the following code in a website: window.onload = resize; window.onresize = resize; function resize(){ heightWithoutHeader = (window.innerHeight - 85) + "px"; document.getElementById("main-table").style.height = heightWithoutHeader; document.getElementById("navigation").style.height = heightWithoutHeader; } The onresize works fine, but the onload event never fires. I've tried it in Firefox and Chrome and neither of them works. Thank you for your help and go for the reputation! ;D 回答1:

问题 Say, user opens a page, clicks on a button, and popup with images appears. How do I detect when all of the images have been loaded? I can't use window.onload here, since the page had already been loaded with all the assets. To make it clear, I want to find out final extents of the popup. Popup is added to DOM like so: var popup = document.createElement('div'); popup.innerHTML = '...'; document.body.appendChild(popup); 回答1: Simply: var image = document.getElementById('image'); image.onload =

问题 How can I use javascript to determine if an HTMLScriptElement has already been fully loaded? How can I determine if a dynamically loaded script has finished loading without using the onload or onreadystate change events? Code is as follows: TOOL.loadScript = function (url, callback, reappend, deepSearch) { var head, curr, child, tempScript, alreadyAppended, queue, alreadyHandled, script, handler, loadFunc; head = document.getElementsByTagName("head")[0]; tempScript = document.createElement(

问题 I'm new to JavaScript and therefore confused for the variable scope... I'm trying to load an image, and replace it with another URL when it doesn't exist. I have to do it in pure JavaScript. Here I got 2 versions extremely alike, but they perform differently. The only thing in common is: they don't work. The 3rd version requires a refresh and doesn't work under IE. d is the object with number attribute, which has no problem. Here is what they have in common .attr("xlink:href", function (d) {
