Validating your website
As I mentioned before, information is passed to the validation function in the event object, and in the code we see that the member ‘value’ is used to communicate the current value of the field.
The member ‘rc’ (or return code) is used to communicate back if the validation was successful or not.
The best is to choose a niche you are passionate about. You know, there’s fulfillment in connecting with others and providing helpful information.
To learn more about the event object, take a look at JS.88.560– make sure to click on the button in the upper left corner to display the navigation pane if it’s not shown automatically.
Let’s take a look at how to do that with a text field that is only supposed to have a value of either ‘AAAA’ or ‘BBBB’ (yes, I know that this does not make much sense in a real PDF form).
So, if the user enters ‘01234’ we should see an error message that would instruct the user about what type of data is valid for this field.
The Tools page has information on specific test tools known to be available.
If you run your own DNS server, you can use the exists: mechanism to capture information on where mail from your domain is being sent from.
