PDF Form spawned page reset fields only on spawned page

In order to reset only the fields on a spawned page you need to use a script that dynamically works out the name of the fields to reset. 

For example. If the button is named "Reset". Then on the spawned page it will be named "P#.TemplateName.Reset".

If you were to hard code the reset field names, then you would need to run this script.

this.resetForm( "P#.TemplateName");

To generalize the code so that it works on any template page, the script needs to extract the template prefix from the name of the reset button. Like this:

var strPrefix = event.targetName.split(".").splice(0,2).join(".");

this.resetForm(strPrefix);
