When I put any sort of doctype declaration like <!DOCTYPE html >, appendChild does not work.... Why?
<form>
<script language="javascript">
function function2() {
var myElement = document.createElement('<div style="width:600; height:200;background-color:blue;">www.java2s.com</div>');
document.forms[0].appendChild(myElement);
}
</script>
<button onclick="function2();"></button>
</form>
I'm trying to get data from a popup window's parent opener...is that possible? The data can be a string literal or value tied to the DOM using jQuery .data()
If you're having this problem in IE, it's probably because the presence of a DOCTYPE declaration forces the browser into "standards-compliance" mode. This can cause code that doesn't conform to expected standards to break.
In your case, it's probably because document.createElement doesn't accept an HTML fragment - it accepts an element name, e.g. document.createElement('div').
Try replacing your function body with something like this:
var myElement = document.createElement('div');
myElement.style.width = '600px';
myElement.style.height = '200px';
myElement.style.backgroundColor = 'blue';
myElement.appendChild(document.createTextNode('www.java2s.com'));
document.forms[0].appendChild(myElement);

Also, jQuery is good for easily creating elements using the syntax you specified.
