XForms/Dynamically Load JavaScript

Motivation
Sometime XForms data elements don't do everything you need. This is especially true for exception handling. When this happens you can dynamically load a JavaScript program to handle the required functionality.

This example will use the XForms load element. But unlike most JavaScript functions, it will not be loaded into the browser until it is needed.

Sample Program
Here is an example of using the load element within an XForms trigger:

First you will need a small JavaScript funtion to test like the following:

Then you can call this JavaScript function using the Load function within a trigger:

Load XForms Application

You can also pass data from an XForms instance by using the following example:

When the user selects this trigger the JavaScript function my-javascript-function will be dynamically loaded into the XForm application and executed.
