Jquery ('#iframeid').load() 在加载 Iframe 内容(文本、图像)之前执行
我正在尝试访问 Iframe 的 Iframe 的数据。为了强制我的 javascript 函数等待,我使用 jqueries .load 函数。但我的 javascript 代码仍然“有时”在 iframe 的内容完全加载之前执行。有时我的意思是不同的计算机的行为是不同的。在较慢的计算机上,它大多数时间都会等待较快的计算机,代码几乎总是被执行。所以我怀疑 Internet Explorer 8 过早触发了 onload 事件。是否有任何 jquery 函数可以等待 iframe 的所有元素加载完毕?
这是我的代码:
function parsePeopleLink(){
try{
//This is where I check if the wanted I frame already exists
if(document.getElementById('isolatedWorkArea') != null) {
if(window.frames[2] != null) {
if(window.frames[2].name == 'isolatedWorkArea') {
//This is where I want the following code only to be executed when the Iframe's content is fully loaded, otherwise I get an access denied error when trying to change Userlinks
$('#isolatedWorkArea').load(function() {
for( var i = 0; i < window.frames.length; i++){
for(var j = 0; j< window.frames[i].document.frames.length; j++){
IframeDocument = window.frames[i].document.frames[j].document;
changeUserLink(findPeopleIDfix(findPeopleID(IframeDocument)),findUserLinks(IframeDocument),8, IframeDocument);
}
}
});
}
else {
throw e; //I know that all the nested else statements are ugly, I just inserted them for testing purposes
}
}
else {
throw e;
}
}
else {
throw e;
}
}
catch(e) {
//alert(e.description);
for(var k = 0; k < window.frames.length; k++)
{
IframeDocument = window.frames[k].document;
changeUserLink(findPeopleIDfix(findPeopleID(IframeDocument)),findUserLinks(IframeDocument),9, IframeDocument);
iframeindex++;
}
}
}
所有 Iframe 都有:相同的端口、协议和 src。 非常感谢帮助
I'm trying to access data of an Iframe's Iframe. To force my javascript function to wait I use jqueries .load function. But still my javascript code get's executed "sometimes" before the iframe's content is fully loaded. By sometimes I mean that the behavior is different for different computers. On slower computers it waits most times for fasters computers the code gets almost always executed. So I suspect that Internet explorer 8 fires the onload event to early. Is there any jquery function to wait until all elements of an iframe are loaded?
This is my code:
function parsePeopleLink(){
try{
//This is where I check if the wanted I frame already exists
if(document.getElementById('isolatedWorkArea') != null) {
if(window.frames[2] != null) {
if(window.frames[2].name == 'isolatedWorkArea') {
//This is where I want the following code only to be executed when the Iframe's content is fully loaded, otherwise I get an access denied error when trying to change Userlinks
$('#isolatedWorkArea').load(function() {
for( var i = 0; i < window.frames.length; i++){
for(var j = 0; j< window.frames[i].document.frames.length; j++){
IframeDocument = window.frames[i].document.frames[j].document;
changeUserLink(findPeopleIDfix(findPeopleID(IframeDocument)),findUserLinks(IframeDocument),8, IframeDocument);
}
}
});
}
else {
throw e; //I know that all the nested else statements are ugly, I just inserted them for testing purposes
}
}
else {
throw e;
}
}
else {
throw e;
}
}
catch(e) {
//alert(e.description);
for(var k = 0; k < window.frames.length; k++)
{
IframeDocument = window.frames[k].document;
changeUserLink(findPeopleIDfix(findPeopleID(IframeDocument)),findUserLinks(IframeDocument),9, IframeDocument);
iframeindex++;
}
}
}
All Iframes have: same port, protocoll, and src.
Help is much appreciated

Javascript 无法访问外部内容以在完全加载后进行监视。如果您有权访问 iframe 内容,则可以添加对父窗口函数的调用来触发它。
父页面:
框架页面:
Javascript can't access external content to monitor when it's completely loaded. If you have access to the iframe content you can add a call to the parent window's function to trigger it.
Parent Page:
Framed Page:
我在我的一个项目中使用了类似的东西。我正在尝试下载文件,并在下载完成后显示消息。根据我的经验,这种事情不起作用:
Load 事件在 iframe 用 HTML 编写后立即触发,而不是在 iframe 加载其所有内容时触发。但这段代码有效:
这段代码等待我的文件下载,然后触发加载事件。我想这对你也有用。
I used something like that in one of my projects. I was trying to download a file, and show message after download finished. This kind of thing didn't work in my experience:
Load event fires immediately after iframe is written in HTML not when iframe loads all of its contents. But this code worked:
This code waited for my file to download then fired load event. I think this could work for you too.
我想当 i 框架内容在 IE 上完全加载时隐藏等待的微调 div,
我几乎尝试了 Stackoverflow.Com 中提到的所有解决方案,但都没有达到我想要的效果。
然后我有一个想法,当 i 帧内容完全加载时,可能会触发 $(Window ) load 事件。
这正是发生的事情。
所以,我写了这个小脚本,并且像魔术一样工作:
希望这会有所帮助。
I wanted to hide the waiting spinner div when the i frame content is fully loaded on IE,
i tried literally every solution mentioned in Stackoverflow.Com, but with nothing worked as i wanted.
Then i had an idea, that when the i frame content is fully loaded, the $(Window ) load event might be fired.
And that exactly what happened.
So, i wrote this small script, and worked like magic:
Hope this helps.
你如何/在哪里触发 iframe 的加载?如果您检查这些解决方案,则会发现以下模式:
据报告有效。
类似的报告解决方案:
动态插入的 iframe 中的 jQuery .ready
IFRAME 加载完成时的 JavaScript 回调?
编辑:
看起来像 Nick Spiers有正确的答案,或者至少它是你问题的一部分。 iframe 内容的访问问题。
How/where are you triggering the load of the iframe? If you check these solutions a pattern of:
is reported to work.
Similar reported solutions:
jQuery .ready in a dynamically inserted iframe
Javascript callback when IFRAME is finished loading?
Edit:
Looks like Nick Spiers has the right answer, or at least it's part of your problem. Access issues on the iframe contents.
