Replicants and dynamic contents?

Piers

Hope someone can advise.

I'm looking for away of either pasing a parameter to my .js function (which I think is impossible), or being able to access which element was clicked from within the function.

I have a group of three fields which can be replicated, field 2 changes on field 1, and field 3 on field 2.

I do not want to have to replicate my function 6 or 10 times, just because a single pararameter is changing - EXTREMELY inefficient. Maybe I am missing something.



My code for reference for a single instance looks like this:

function update_data()
  {

    var optionsArray =IWDatacapture.getItem("/CST[1]/Category").getOptions();

    var dest="";

    var recID =optionsArray[IWDatacapture.getItem("/CST[1]/Category").getValue()].value;

    var objXML = new ActiveXObject("Microsoft.XMLDOM");
    objXML.async = false;

    var ok = objXML.load("/iw-mount/default/main/ba_uk/WORKAREA/test/test/XMLResults.asp?ID=" + recID);

     if (ok == false)
    {
      alert("XML Error: " + objXML.parseError.reason)
    }
 else

 {
      //Grab resulting elements
      var xmlNodes = objXML.selectNodes("//elem");

      //populate drop-down

       populate_dropdown_values(xmlNodes, "/CST[1]/Subject")
 }
  }
  //************************************************************
  function populate_dropdown_values(objNodes, sel)
  {
    newOptions = new Array();  
    //loop thru nodes, adding to drop-down
    for (var z=0; z<objNodes.length; ++z)
    {
   newOptions = new Option (objNodes.getAttribute("text"),objNodes.getAttribute("id"),false,false); 
    }
 //set first item in list to be default
  newOptions[0] = new Option (objNodes[0].getAttribute("text"),objNodes[0].getAttribute("id"),true,true); 
    IWDatacapture.getItem(sel).setOptions(newOptions);
    IWDatacapture.redraw() 
   }
IWEventRegistry.addItemHandler("/CST[1]/Category", "onItemChange", update_data);
