need help making a javascript work

TheMSsForum.com: The Microsoft Software Forum

hi. i want to assign different background image to a web page according to
the query string in the URL. so i write this javascript ...


thisURL = window.location;
if (thisURL.indexOf('bio') != -1) {
document.body.background = "bg2.jpg"
}


... only to find that it doesn't work!

what is wrong with it? thanks.

Hi Xero,

The problem is that you're getting the object "location" versus the URL string which is contained in window.location.href.

To retrieve a query string use
function qsobj(parm)
{
var qpairs = document.location.search.substring(1).split("&")
var qvbl = qpairs[parm].split("=")
return qvbl[1] ? unescape(qvbl[1].replace(/%20|\ +/g," ")) : null
}

So if you call the page as
thepage.html?bgcol=bg2.jpg
then the JS in thepage.html would be (not tested)
<head>

<script type="text/javascript">
function qsobj(parm)
{
var qpairs = document.location.search.substring(1).split("&")
var qvbl = qpairs[parm].split("=")
return qvbl[1] ? unescape(qvbl[1].replace(/%20|\ +/g," ")) : null
}
document.body.background = qsobj(0)
</script>

</head>

I'm confused how does this have anything to do with the question asked?
