help parsing window.location.href

[wkenny]

Can anybody tell me how to parse window.location.href to get the page name.
e.g. thesite/thefolder/thesubfolder/thepage.htm
and I want to return "thepage"
I will not know in advance how deep the page name is.
Thanks

<script type="text/javascript">
thePage=unescape(location.href)
thePage=thePage.substr(thePage.lastIndexOf('/')+1)
thePage=thePage.substr(0,thePage.indexOf('.')-1)
alert(thePage)
</script>

Not foolproof but, good for normal page names without query strings* containing the '/' character.

*query strings follow the page name with a '?' and data, ex:

thesite/thefolder/thesubfolder/thepage.htm?var1=password

<script type="text/javascript">
thePage=unescape(location.href)
thePage=thePage.indexOf('?')==-1? thePage.substr(thePage.lastIndexOf('/')+1) : thePage.substring(thePage.lastIndexOf('/')+1,thePage.indexOf('?'))
thePage=thePage.substr(0,thePage.lastIndexOf('.')-1)
alert(thePage)
</script>

This one will work even with dots ('.') in the filename and with query strings containing ('/'). There could be other considerations I've missed for other potential location.href values.

Just the trick. Thanks a lot, John

Actually, looking at it again, my second version will still fail on query strings containing ('/'). Use:

<script type="text/javascript">
thePage=unescape(location.href)
if(thePage.indexOf('?')!==-1)
thePage=thePage.substring(0,thePage.indexOf('?'))
thePage=thePage.substr(thePage.lastIndexOf('/')+1)
thePage=thePage.substr(0,thePage.lastIndexOf('.'))
alert(thePage)
</script>

Or just use %2f instead of / in GET query strings, like you're meant to.

[jscheuer1]

After it is unescaped, what good would that do?

[Twey]

None... but who mentioned unescaping it?

/EDIT: Oh wait, you did. I see why; perhaps unescape it after getting the appropriate portion? Check for ., then if it's -1, use %2e instead.

[jscheuer1]

I think unescaping it in the first place is the safest route, no telling what you are dealing with before that.

[Twey]

You can't escape the path, only the page. Split the page down, then unescape it. You needn't worry about the path.
