Does anyone have an example where javascript is used to insert an action with creation of a button?

[Julie218445359s08]

Working on a command that started from an example in Developing Acrobat Applications Using JavaScript and I modified it to look through fields of a form and if any page has a signature field and the field name is like “Performed” then place a button on that page. Got this working now and for the next iteration I would like to insert a lenghty java script or maybe make a custom function and would really appreciate any pointer or examples to modify last line of the example code given.

Thanks in advance for any help offered!

for (var i=0; i<this.numFields; i++) {
var fname = this.getNthFieldName(i)
var f = this.getField(fname);    
    if (f.name==null || f.type=='button'||f.type=='radiobutton'||f.type=='text') continue;
    if (f.type=='signature' && /Performed/.test(f.name))
     
// Make the buttons
var pp = addField("Button_", "button", f.page,[ 12, 100, 170, 68 ] );
    pp.buttonSetCaption("Check & Sign Test Case");
    pp.strokeColor = color.gray;
    pp.borderStyle = border.b;
    pp.linewidth = 11;
    pp.fillColor=color.blue;
    pp.textSize = 12;
    pp.textColor = color.white;
    pp.setAction("MouseUp", "Insert script here . . ;");
  }
