Thank you Mark! This is exactly what I wanted.
/* $:/core/modules/widgets/fieldmangler.js */
/....../
{type: "tm-alert", handler: "handleAlertEvent"}
/....../
FieldManglerWidget.prototype.handleAlertEvent = function(event) {
var tiddler = this.wiki.getTiddler(this.mangleTitle),
addition = this.wiki.getModificationFields(),
hadInvalidFieldName = false ;
addition.title = this.mangleTitle;
if(typeof event.paramObject === "object") {
var myalerts = "" ;
for(var name in event.paramObject) {
myalerts += "" + name + ": " + event.paramObject[
name] + ", " ;
}
alert(myalerts) ;
}
return true;
};
