The Name of User Interface Components
Access the various parts of the application object by using the name of a form object, form, item, and so on. A name in the application object has the same function as the tag in the model object omitting the model.app part.
For example, in the line of code
app.form("form1").formObject("button1").set("enabled", false);
the string form1 is the name of a form and button1 is the name of a button.
