I want to take variables passed in URL string and write them to the body of the html page.

See code below.

What am I missing?
<html><head><script type="text/javascript" language="javascript">
 
function parseQString() {
  var qs = new Array();
  var loc = location.search;
  if (loc) {
    loc = loc.substring(1); 
    var parms = loc.split('&');
    for (var i = 0; i < parms.length; i++) {
      nameValue = parms[i].split('=');
      qs[nameValue[0]] = (nameValue.length == 2) ? unescape(nameValue[1]).replace(/\+/g,' '): null;
    }
  }
  return qs;
}
function getQSParm(parm) {
  return (qs[parm]) ? qs[parm] : null
}
var qs = parseQString(); 
 
var Contact0FirtName = "Contact0FirstName"
 
function writetext() {
   document.Contact0FirstName.value=getQSParm("Contact0FirstName");
  }
window.onload=function() {writetext();}
 
</script><body><SCRIPT LANGUAGE=JavaScript>
document.write("Contact0FirstName!");
</SCRIPT>

Here is a better one

<html><head>
<script type="text/javascript" language="javascript">
 
function parseQString() {
  var qs = new Array();
  var loc = location.search;
  if (loc) {
    loc = loc.substring(1); 
    var parms = loc.split('&');
    for (var i = 0; i < parms.length; i++) {
      nameValue = parms[i].split('=');
      qs[nameValue[0]] = (nameValue.length == 2) ? unescape(nameValue[1]).replace(/\+/g,' '): null;
    }
  }
  return qs;
}
function getQSParm(parm) {
  return (qs[parm]) ? qs[parm] : "Not Passed"
}
var qs = parseQString(); 
 
function writetext() {
   document.forms[0].Contact0FirstName.value=getQSParm("Contact0FirstName");
  }
window.onload=function() {writetext();}
 
</script><body><SCRIPT LANGUAGE=JavaScript>
document.write("Contact0FirstName:"+getQSParm("Contact0FirstName"));
</SCRIPT>
<form>

That was not his problem
The problem was syntax AFTER getting the parameters:

1.  document.Contact0FirstName.value is not valid syntax

2. document.write("Contact0FirstName!"); only writes the string Contact0FirstName!

MPlungjan,

<SCRIPT LANGUAGE=JavaScript>
document.write(getQSParm("Contact0FirstName") + '' + getQSParm("Contact0LastName"));
</SCRIPT>

I need a space between the first and last name.

Ok - so why not put one?


document.write(getQSParm("Contact0FirstName") + ' ' + getQSParm("Contact0LastName"));

or

document.write(getQSParm("Contact0FirstName") + '&nbsp;' + getQSParm("Contact0LastName"));
