After
you create your calculations or scripts and tested your form design,
you may discover scripting errors or unexpected field values as
a result of scripting syntax errors.
Designer includes three primary methods for testing and debugging
your calculations and scripts:
-
Using the Designer workspace palettes. For more information,
see
Using the workspace to debug calculations and scripts
.
-
For JavaScript only, using the JavaScript Debugger to assist
you in testing your scripts. For more information about using the
debugger, see
JavaScript Debugging
.
-
Using the host model and event model properties and methods
to troubleshoot your form.
The host model and event model provide functionality that lets
you interact with either the host application or the various form
events. These models are useful for returning information that can
assist you in debugging calculation and scripts.
For example, the following script returns a message at run time
indicating the name of the event on which the script is placed.
This indicates that a particular event has fired:
xfa.host.messageBox(xfa.event.name) // FormCalc
xfa.host.messageBox(xfa.event.name); // JavaScript
Another example of using the host model and event model methods
is to obtain the value of a field on an interactive form before
a user manually changed it. This is useful for observing how the
objects on your form design respond to user-entered data:
xfa.host.messageBox(xfa.event.prevText) // FormCalc
xfa.host.messageBox(xfa.event.prevText); // JavaScript
