Prefilling in a Multiple line text field with Values using Javascript on a NewForm.aspx

Recently I had to take 3 single column fields and condense them into 1 multiple text field.  Those 3 columns are Name, Location and Code.  However, to make it easy for people to fill out I want these names to be pre filled in on a new display form that looks like this

Name:

Location:

Code:

This is to have some sort of organization in the column when they need to fill in the data.  I found a blog post but this was for 2007 titled "Using Javascript to Manipulate a List Form Field".

. 

I did try to use this javascript code on 2010 and so far Sharepoint is taking kindly to it, it seems.  My issue is that I am unsure as to where to put my values. 

My thoughts are that I have to replace nameVal with my values because I am inputting them into the text field. 

Any help would be great as I am still learning Javascript and am no expert with it. 

    _spBodyOnLoadFunctionNames.push(“fillDefaultValues”);



    function getTagFromIdentifierAndTitle(input, TextField,  Name, Location, Code ) {

      var len = identifier.length;

      var tags = document.getElementsByTagName(input);

      for (var i=0; i < tags.length; i++) {

        var tempString = tags[i].id;

        if (tags[i].title == title && (identifier == “” || tempString.indexOf(identifier) == tempString.length – len)) {

          return tags[i];

        }

      }

      return null;

    }



    function fillDefaultValues() {

      var qs = location.search.substring(1, location.search.length);

      var args = qs.split(“&”);

      var vals = new Object();

      for (var i=0; i < args.length; i++) {

        var nameVal = args[i].split(“=”);

        var temp = unescape(nameVal[1]).split(‘+’);

        nameVal[1] = temp.join(‘ ‘);

        vals[nameVal[0]] = nameVal[1];

      }

      // Set HTML element default values here

    }
