.InnerHTML Not working properly in Internet Explorer
I wanted to assign a link tag to innerHTML of a HTML control. But this is not working properly in Internet Explorer. However when I try to assign anything other than <link> & <style> tags it works fine.
<html>
<head>
<script type="text/javascript">
function ge开发者_运维百科tValue()
{
var x=document.getElementById("myHeader");
x.innerHTML='<link \"http://test.com/css/template.css\" rel=\"stylesheet\"><div>abc</div>';
alert(x.innerHTML);
}
</script>
</head>
<body>
<h1 id="myHeader" onclick="getValue()">Click me!</h1>
</body>
</html>
Also, If I change sequence of <div> tag and <link> tag above it works fine in Internet Explorer also.
x.innerHTML='<div>abc</div><link \"http://test.com/css/template.css\" rel=\"stylesheet\">';
Please suggest! Thanks.
EDIT: This is a bug in Internet Explorer with ExtJs. More information at

innerHTML won't work in IE, but using DOM methods it will:
function getValue()
{
var x=document.getElementById("myHeader")
, link = document.createElement('link')
, div = document.createElement('div');
x.innerHTML = '';
x.appendChild(link);
x.appendChild(div);
div.innerHTML = 'abc';
link.href = 'http://test.com/css/template.css';
link.rel = 'stylesheet';
alert(x.innerHTML);
}
Although the reference states a link tag may only appear in the header, interesting enough the style link does work if you use the code I provided, in all browsers I tried (IE, firefox, chrome). See this jsfiddle (where I used a real css-href from test.com ;-)
If you however want to place the link in it's rightful section (<head>), use:
var header = document.getElementsByTagName('head')[0];
, link = document.createElement('link');
header.appendChild(link);
link.href = 'http://test.com/css/template.css';
link.rel = 'stylesheet';
For starters, you are missing an href attribute on your <link>.
<link href=\"http://test.com/css/template.css\" rel=\"stylesheet\" />
And don't put link and style tags into the <body>. Inject them into the <head>
var link = document.createElement("link");
link.href = "http://test.com/css/template.css";
link.rel = "StyleSheet";
document.head.appendChild(link);
A lot of people are missing the point here. What he is trying to do ( after fixing the typo where the href attribute is missing ) works in any other browser.
IE 8 and below have a bug where if the first element in the text when setting innerHTML is a tag (maybe others), it is ignored. If you just put a space or newline or other tag first, it works.
He even discovered this when he said putting the <div> first fixes it.
It isn't valid, but that's how you fix it.
Edit: in other words: foo.innerHTML = "\n" + yourHtmlWithLinkInIt;
<link> can only be contained in <head>.
This element defines a link. Unlike A, it may only appear in the HEAD section of a document, although it may appear any number of times.

i think the problem is that the <link> hast to be an empty element. change your code to this:
x.innerHTML='<link \"http://test.com/css/template.css\" rel=\"stylesheet\" /><div>abc</div>';
// this is the trick ^^^
EDIT: i havn't tested this, but it's the first thing that hurts my eyes.
EDIT2: <link> tags should only occur inside of the <head>-section... i hope you know what you're trying to do.
to the set text properly, i would recommend you to go what i generally do. if you have ie 8 then open the html in ie. press f12 to show the developer tool. now in the new window go to script tag. set break point from where your javascript starts. now press on the button start debugging. execute the js function from your by some event or the way it executes. now on the object in the javascripg function, when the break point hits, right click and add watch. expand the object and see, where your earlier text was and where is your new text.
What exactly are you trying to achieve, as your end goal? As said previously a link tag should really only appear in the <head> of an html document.
JavaScript can be a tricky thing in its vanilla flavour, you're better off using a framework, my personal favourite is MooTools though I hear JQuery is pretty good, but MooTools has OOP (for real programmers - tehe).
This'll allow you to do a lot more, and probably get to your end goal, if you let me / us know then you should get a more direct answer to your issue.
The thing is it works in FireFox and Google Chrome, but not in IE.
This is, because you cannot set the innerHTML tag of InternetExplorer with a string, if the string is more than text, ie a HTML element.
I experienced this trying to dynamically populate a ComboBox into a table cell with AJAX...
The solution is to use JQuery.
Then you can do:
$("#YourElementID").html('<link \"http://test.com/css/template.css\" rel=\"stylesheet\" /> <div>abc</div>');
and JQuery will do the DOM stuff, that selbie and KooiInc describe, for you.
Found different and easy solution here for "link" and "sytle", but "script" needs to be added using appendChild. Very much similar to what Vectorjohn has said, also provides more references.
