app.alert("Invalid value for field " + event.target.name);
event.rc = false;
}
For a
calculate
event, JavaScript should set this property. This is the value that the field should
take upon completion of the event. For example, the following JavaScript sets the calculated
value of the field to the value of the SubTotal field plus tax.
var f = this.getField("SubTotal");
event.value = f.value * 1.0725;
For a
format
event, JavaScript should set this property. This is the value used when generating
the appearance for the field. By default, it contains the value that the user has committed. For
example, the following JavaScript formats the field as a currency type of field.
event.value = util.printf("$%.2f", event.value);
willCommit
Type: Boolean
Event: Keystroke
Access: R
Use this property to verify the current keystroke event before the data is committed. This is
useful to check the target form field values and for example verify if character data instead of
numeric data was entered. JavaScript sets this property to
true
after the last
keystroke
event
and before the field is validated.
Example:
var value = event.value
if (event.willCommit)
// Final value checking.
else
// Keystroke level checking.

willCommit,

(Aform.js) in your Acrobat plug-ins directory.
