[Javascript] Extract portion of URL and place in form field

[Muchacho, Laurent (TWIi London)]

Hi Colin 

I found that function a while ago that might help you 
you just need to call the function like that or by any other way you know

>This is the string...
>http://www.mysite.com/thanks.html?cbreceipt=Z54HKPT7
>
>I'm after the Z54HKPT7.

<a href="javascript:QueryString('cbreceipt')"></a>

and you will get the Z54HKPT7

there is the function 

function QueryString(param){

  var begin,end;
  if(self.location.search.length>1)
  {
    begin=self.location.search.indexOf(param) +param.length+1;
    end=self.location.search.indexOf("&",begin);
    if(end==(-1)) end=self.location.search.length;
    return(self.location.search.substring(begin,end));
  }
  else if(self.location.hash.length>1)
  {
    begin=self.location.hash.indexOf(param) +param.length+1;
    end=self.location.hash.indexOf("&",begin);
    if(end==(-1)) end=self.location.hash.length;
    return(self.location.hash.substring(begin,end));
  }
  else return("");

}

// Use split.
var string="http://www.mysite.com/thanks.html?cbreceipt=Z54HKPT7";
var getit= new Array();
 getit=string.split("=");
alert(getit[1]);
var result=getit[1];
window.document.yerform.fieldname.value=result;

// sorry about that.

Of course, you'd need to send the result to your form, not just alert it.
