Need help with script

**blm126** · 09-25-2005, 06:47 PM

I'm trying to write a script that can access a variable stored in the url. Like somefile.html?something=variable
Right now I've got a script that works but I would like to streamline it.

My current script is

HTML Code:

<head>

<SCRIPT LANGUAGE="javascript">



function urlvar1()
{	
var locate = window.location
document.locform.loc.value = locate
var loc = document.locform.loc.value
var start = loc.indexOf("=") + 1
var result = loc.substring(start)
return result
}

</SCRIPT>
<body>
<FORM NAME="locform">
<INPUT TYPE="hidden" NAME="loc">
</FORM>

<script type="text/javascript" language="javascript">


document.write(urlvar1())
</script>


</body>

It works,but I want to find a way to get rid of the form. Right now I'm using it to turn window.location property into a string. Does anyone know another way to turn the url into a string. I want all the code to go in the function urlvar1() so all you do is link to the script then call the function without the extra html.

window.location.href is a string.

So this rears its ugly head again, does it?

Someone else posted code very similar to that earlier this year after obtaining it from a very badly written article found on the Web. A better solution would use regular expressions (which I posted in that thread), though something reliable but much bulkier could be written without them.

Does anyone know another way to turn the url into a string.

The JavaScript 1.0 approach, which could have been used in the original article, would be concatenation with an empty string:

Code:
