Iframe or Frane set auto redirect

varriable redirects from a sigle iframe

[griddesign]

I need to redirect a single iframe on one website to several different pages with another website based on multiple href links from a email.

So the rout is: email links > to one iframe to > multiple varriable web sites based on the varriables on the orriginal email links.

I am not a programmer so any help much appreciated.

I assume the orriginal links will need varriables appended to them

i.e.

[mywebsite.com?link1...]
[mywebsite.com?link2...]
[mywebsite.com?link3...]

these varriables will then be picked up by some javascript in the iframe and redirect accordinly to what ever the varriables are assigned to.

Many thanks in advance.

In the page that creates the iframe, use this;

<script type="text/javascript">
function getURLParam(strParamName){
var strReturn = "";
var strHref = window.location.href;
if ( strHref.indexOf("?") > -1 ){
var strQueryString = strHref.substr(strHref.indexOf("?"));
var aQueryString = strQueryString.split("&");
for ( var iParam = 0; iParam < aQueryString.length; iParam++ ){
if (aQueryString[iParam].indexOf(strParamName + "=") > -1 ){
var aParam = aQueryString[iParam].split("=");
strReturn = aParam[1];
break;
}
}
}
return strReturn;
}

switch(getURLParam('link')*1)
{
case 1:
document.write('<iframe src="http://www.site1.com"></iframe>');
break;
case 2:
document.write('<iframe src="http://www.site2.com"></iframe>');
break;
default:
document.write('<iframe src="http://www.site3.com"></iframe>');
}
</script>

And your links need to look like this;

http://www.example.com?link=1
http://www.example.com?link=2
http://www.example.com?link=3

I haven't actually tried it but it should work.
