dynamic equivalent ?

Jon Paal

this works as shown:

<script Language="javascript" src="http://127.0.0.1/syndicate.ashx?d=suppliers"></script>

is there a way to set src programmatically ??

It uses my own library as an example, but this did work for me:

<html>

<body>
<script id="script1" type="text/javascript"></script>

<script type="text/javascript">
document.getElementById("script1").src="/Ajax/ajax.js";
</script>

<script type="text/javascript">
var ajax = new AjaxRequest();

ajax.doTextRequest("http://www.google.com", "GET", "", update, true);

function update() {
document.getElementById("goog").innerHTML = ajax.getValue();
}
</script>

<div id="goog"></div>
</body>

</html>

i was hoping to get to something like below, but it doesn't return anything when src is dynamic. Only seems to work when src is in
the script tag at the time page is loaded.

====================================

<script Language="javascript" >

function switchsrc(id){
var mysrc;
switch (id)
{
case 1:
//alert (1);
mysrc = "suppliers";
break;
case 2:
//alert (2);
mysrc = "customers";
break;
}

document.getElementById("ashx").src = "http://127.0.0.1/syndicate.ashx?d=" + mysrc ;
}

</script><br>

<script type="text/javascript" id="ashx" ></script>

================================================

}
</script>

<div id="goog"></div>
</body>

</html>

Did you test it in anything besides IE? You should test it there as the
only UA that allows the changing of the .src property of a script
element is IE.

Although dynamically creating script elements is very widely supported,
you simply createElement('script') and then set it's .text property to
the script block.

The claim was "this works" when it doesn't "work" reliably. It is always
nice though to see people back track to the "IE only" path only after
being told the hack code they were given is IE only. The other nice one
is "Its an IE only intranet".

Your newsreader hasn't even made it to the level of being defective.

Yep, that's the way external src= works.

the question was how to make it dynamic.

Search the archives for my name along with the function name of
loadJSFile and you will find this function:

function loadJSFile(fileURL){
var newScript = document.createElement('script');
newScript.type = "text/javascript";
newScript.src = fileURL;
document.getElementsByTagName('head')[0].appendChild(newScript);
}

And call it as such:

loadJSFile('http://www.someDomain.com/someJSFile.js')

It is *that* simple.

Answer:It destroys the order of the conversation
Question: Why?
Answer: Top-Posting.
Question: Whats the most annoying thing on Usenet?

thanks for replying..

seems this just isn't going to work.

In Firefox the output replaces the entire page instead of filling a placeholder and page never finishes running.

Just won't work in IE, at all.

function loadJSFile(fileURL){
var newScript = document.createElement('script');
newScript.type = "text/javascript";
newScript.src = fileURL;
document.getElementsByTagName('head')[0].appendChild(newScript);
}

And call it as such:

loadJSFile('http://www.someDomain.com/someJSFile.js')

It will work, you just have to make it work.

In Firefox the output replaces the entire page instead of filling a placeholder and page never finishes running.

Then you probably have document.write statements in your .js files.

Just won't work in IE, at all.

Post a URL to a sample page.

No I didn't (obviously). I need to remember to do that when making

Thanks for the heads up. What if you wanted to include a prepackaged
..js file rather than an actual block of script?

Thanks for the heads up. What if you wanted to include a prepackaged
..js file rather than an actual block of script?

Then you set the new script element's .src property instead of its .text
property:

function loadJSFile(fileURL){
var newScript = document.createElement('script');
newScript.type = "text/javascript";
newScript.src = fileURL;
document.getElementsByTagName('head')[0].appendChild(newScript);
}

And call it as such:

loadJSFile('http://www.someDomain.com/someJSFile.js')

If you want to execute script code then use something like this:

function executeJSCode(stringToExecute){
var newScript = document.createElement('script');
newScript.type = "text/javascript";
newScript.text = stringToExecute;
document.getElementsByTagName('head')[0].appendChild(newScript);
}

And call it as such:

executeJSCode('String of code here without script tags')
