using window.location

**marringi** · 03-26-2008, 05:38 PM

hello,

The thing is, I'm using a perl database program and I am going print out many types of the database in one html file. This is no problem using  in a shtml file.

But what I am hoping to accomplish is that I could write in the window location: file.shtml?process=something. Something would be written instead of data. Then I wouldn't have to create I new shtml file for each database. I'm pretty sure that this isn't possible with JavaScript but I was hoping someone here could maybe help me, that is if it is possible.

Thank you

  alert('Query Variable ' + variable + ' not found');
}
</script>

Now make a request to page.html?x=Hello

Code:

<script>
  alert( getQueryVariable("x") );
</script>

will allow you to gain access to the GET variables passed into the url address

Thanks for the response. I'm not getting it to work. Do I use this with a .shtml file, or how do I use it?

Say I wanted to get this location put into the page file: script.cgi?database=nr1&search=..

and then and the x=hello query... how will do this?

I hope I'm making myself clear enough, so that we understand each other.

From what I understand, just put it in your .shtml file, put it in the body section[I think], and everything should be fine, then do visit the address you'd go to:
*.shtml?x=Hello
I hope this helps.

Do you mean that i should do this:

<html>
<head>
<title></title>
<script>
function getQueryVariable(variable) {
var query = window.location.search.substring(1);
var vars = query.split("&");
for (var i=0;i<vars.length;i++) {
var pair = vars[i].split("=");
if (pair[0] == variable) {
return pair[1];
}
}
alert('Query Variable ' + variable + ' not found');
}
</script></head>
<body>



</body>
</html>
