Setting a field as required at run time

This example demonstrates how to make a field required at run time.

In this example, when the Set as Required button is clicked, if the form filler attempts to submit a form without typing some text in TextField1, an error message appears.

Scripting for the Set as Required button

The following script is for the Set as Required button:

TextField1.validate.nullTest = "error";

You can also use one of these two scripts:

    TextField1.mandatory = "error"  
    TextField1.mandatoryMessage = "this field is mandatory!"
