Form validating

Adobe provided a lot of infrastructure to do that with just a simple script.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).Here you can see screen captures from Firefox and Chrome: Text alert messages are generated entirely by the browser and will even translate automatically into different languages - something that would be almost impossible using just Java Script.The advantage for the user is that it's obvious whick element is causing the problem and there's no alert window that needs to be clicked away.The CVU will continue to work closely with the various agencies in higher education concerned with quality assurance and will enhance its links with further education colleges and private providers of higher education.As well as running several events every year to disseminate good practice and share information of interest to our members the CVU: An important feature of CVU is networking.If you skip the message for a validation, the default message is displayed.

The term ‘collaborative provision’ is often used to describe this form of partnership.Not the prettiest solution, but functional in all browsers with Java Script enabled.Adding HTML5 validation to the checkbox is actually very simple.After the “Edit” button is clicked, a new window will open that allows us to edit the new script: This script also includes a check for an empty string, so that the user can wipe out a wrong string and start from scratch.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.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.
