Moving Objects Around a Form
- Niall O'Donovan

- Not yet rated.
Problem

Allowing a user to move objects (in this case buttons) around the form. We wanted the user to be able position markers within a grid. The number (caption) of the button related to a particular solution in a table.

Solution

This solution is based on the "fly swatter" example by Thom Parker (http://www.pdfscripting.com) and samples by John Brinkman (http://blogs.adobe.com/formfeed/) looking at x, y, w and h properties.

Problem

I have created a form that has two comboboxes with the simple selections of YES or NO in them. If the user goes and selects YES in ComboBox A then i want ComboBox B to appear in the form and become required. Else I basically want the from to stay the same. I started by writing an if statement that would run on exit of the combobox A and i dont know if that is the correct place to run it or not. Can someone please help me on writing this script? Thanks!!

Solution

This problem involves 2 concepts. The first concept involves the understanding between static and dynamic forms and the second is how to apply JavaScript to objects on the form. We will address how to use both to make components appear and disappear based on logic in your form.

Problem

Typically, you'd need to open up each redaction annotation's properties dialog to change or set the redaction code one at a time. This can be tedious and time consuming.

Solution

With just a few lines of JavaScript, you can dramatically reduce the number of steps.
Enforcing Required Fields

Problem

Setting a form field to “Required” in the “General Properties” tab forces the user to fill in the selected form field. But there are cases when you need the user to fill out a particular field before moving on to the rest of the form. You could use JavaScript to dynamically enable or disable parts of the form but that can be cumbersome to keep track of. The ideal situation would be to, where appropriate, force the user to enter data into a required field before moving to another field.

Solution

Add the following code to the “On Blur” action of the field you want to be required.
