Non-Sequential Dynamic Picklist

I know I haven't posted to my blog in a long time because I have been busy with work.

Here is something that I finished up today.

I needed to create a set of dynamic picklists that could be non-sequential. The SDK gives a solution for a sequential based picklist, but that doesn't take in account for additional values in the future. I found this post by Greg Owens' post here and have edited and rearchitected parts of it. Since he helped me out, I have decided to post it to help you out!

Feel free to post comments. Thank you again Greg!

//**Non-Sequential Dynamic Picklist
//**------------------------
//**Developers: Greg Owens (Initial structure)
//** Mark Nagao (Rearchitecture)
//**Date: December 17, 2007
//**Purpose: Dynamic SubPicklist of non-sequential values
//**MSCRM 3.0: OnChange Event Code
//****************************************************************
//****************************************************************
//**Assign your main and sub picklist
var oPicklist= crmForm.all.new_mainpicklist;
var oSubPicklist = crmForm.all.new_subpicklist;

//**End of Assignment editing
//****************************************************************

//Saving and Resetting Original Picklist Values
if(!oSubPicklist.originalPicklistValues)
{
oSubPicklist.originalPicklistValues = oSubPicklist.Options;
}
else
{
oSubPicklist.Options = oSubPicklist.originalPicklistValues;
}

//****************************************************************
//**Add Arrays and specify values to display in SubPicklist

var oArray1 = new Array(0,1,3,4);
var oArray2 = new Array(0,2,5,6);


//**End of ARRAY Editing
//****************************************************************

//Check that Main Picklist value is not Null
if(oPicklist.DataValue != null)
{
switch(oPicklist.SelectedText)
{

//****************************************************************
//**Edit Case: Add a case for each Array

case "Array1":
filterPicklist(oArray1);
break;

case "Array2":
filterPicklist(oArray2);
break;


//**End of CASE editing
//****************************************************************

}
}

//Function to Filter SubPicklist
function filterPicklist(oDesiredOptions)
{

//Create temporary array to hold selected Values
var oTempArray = new Array();
//FOR loop to cycle through all SubPicklist Values
for (var i=oSubPicklist.length;i >= 0;i--)
{
//FOR loop to cycle through desired SubPicklist Values
for (var j=oDesiredOptions.length;j >= 0;j--)
{
//Compare i(SubPicklist Value) and j(Desired Value)
if (i == oDesiredOptions[j])
{
oTempArray[i] = true;
oDesiredOptions.splice(j,1);
}
}
}
//FOR loop to cycle through all SubPicklist Values
for (var i=oSubPicklist.length;i >= 0;i--)
{
//Compare with Temporay Array
if(oTempArray[i] != true)
{
//Remove Value from list if not TRUE in Temporary Array
oSubPicklist.remove(i)
}
}
}

//****************************************************************
//**Notes:
// - Place code in the OnChange of the Main Picklist
// - In the array, you must have two values, so if there is
// only one value, then include the 0 (null) value
