check url

[rkoya]

Hi,

I have the following URL:

http://amici/cgi-bin/liveweb.sh/QSearch.w?ctryref=GBR&lang=EN&aff=

I need to check if there is a value for aff, and if there is then hide a div. I know how to hide the div just don't know how to check the URL for a value assigned to aff.

Can anyone help?

Thanks in advance.

var addr = document.location.href;
var aff = addr.substring("aff=");
var affLength = ("aff=").length;
if(aff.length > affLength && aff.indexOf("&") != affLength)
{
 affHasValue = true;
}

aff.length > affLength indicates that URL string exists beyond the "aff=" in the URL

aff.indexOf("&") != affLength indicates that the URL simply isn't something like "...&aff=&east=east&..."

Of course, this assumes that the URL will always have an "aff=" in it, even if there is no value.

Clunky, but...

Alternative, do it like this. (sinfo is the value of the query "aff" if there exists; if not it is empty string.)
[tt]
//through assign or other means to retrieve
var surl="

http://amici/cgi-bin/liveweb.sh/QSearch.w?ctryref=GBR&lang=EN&aff=xyz";

//xyz for testing only

var rx=new RegExp("(\\x3f|\\x26)aff=(.*?)(\\x26|$)");
var cm=rx.exec(surl);
var sinfo=RegExp.$2;
if (sinfo=="") {
alert("no such request variable (aff) or its value is empty");
//do something
} else {
alert("request variable (aff) : " + sinfo);
//do something else
}
[/tt]

Excellent worked perfectly. Thanks for your help guys.

If you in case use substring() parsing, be mindful of any variables named such as "unaff" or alike. You would better control it like either "&aff=" or "?aff=" to be of more certainty.

Hi,

I have hit a problem, I have used the first solution by LFI as there is always an aff in the URL, but where there is aff.indexOf("&") != affLength indicates that the URL simply isn't something like "...&aff=&east=east&..." that doesn't seem to be working as the URL I have tried:

http://amici/cgi-bin/liveweb.sh/QSearch.w?ctryref=GBR&lang=EN&aff=&currcode=

aff is not meant to have a value as & and basically should be disregarded. using my hide method it is actually hiding the div rather than showing it.

Can anyone help

I have figured it out, finally, thanks for help anyway.

Why is the URL showing &aff= instead of &aff=? Do you have control over the building of the URL?
