What version of IE are you using? What is the source for the script you're using?

Try this (complete) example and tell me if it fails and with what error:

Code:

<html>
<body>
<script>
function show_AS(row_num) {
document.writeln("show_AS("+row_num+")<br>");
}

function appendChild(node, text) {
if (null == node.canHaveChildren || node.canHaveChildren) {
node.appendChild(document.createTextNode(text));
} else {
node.text = text;
}
}
/*...*/

var script = document.createElement("script");
script.setAttribute('type','text/javascript');
appendChild(script, "show_AS(1);");

document.body.appendChild(script);

</script>
</body>
</html>

Also think about alternatives to a dynamically created script element. Could you accomplish the same task using (e.g.) events?

Hi,

I tried with your way. but still IE is having some problem. It did not accept node.text = scriptContent;

My IE crashed once that particular line is executed.

But in firefox dynamic <script> element creation is working.

I need your answer. this is very urgent. can you help me out?

thanks

For IE, use 'text' property of script nodes.

IE doesn't allow script tags to have children; the 'text' property can be used instead. Try this:

Code:

/*...*/
function appendChild(node, text) {
if (null == node.canHaveChildren || node.canHaveChildren) {
node.appendChild(document.createTextNode(text));
} else {
node.text = text;
}
}
/*...*/
var script = document.createElement("script");
script.setAttribute('type','text/javascript');
appendChild(script, "show_AS("+row_num+");");

As long as the non-method appendChild is only called on script nodes, you can omit the test of node.canHaveChildren, as it will always be false. I don't know if you're setting the 'type' attribute of the script elsewhere; if not, add that step as above.

Out of curiosity, why do you need to dynamically create the script?

create <script> element problem in IE

Hi,
I'm creating a script tag in this way:

Code:

var text = d.createTextNode("show_AS("+row_num+");");
var script = d.createElement("script"); script.appendChild(text);

where row_num is a counter...(I'm dinamically adding rows to a table)
in Firefox, this works fine...(I have other big problem in Firefox, but I'll hope to ask later this question of the script tag)
in IE it doesn't work: it says that I can't append text to the script element...
any answer?
thanks in advance
Ciao
