Auto-splitting text between two text fields
The scenario
You have a compliant form that has sections for users to fill-in information. Because the form is compliant (i.e. its layout has received the “stamp of approval” and cannot change without another lengthy approval process), the sections cannot grow (they cannot expand-to-fit all of the text users may fill-in). To provide more space for users to add more text, you’ve provided an expandable “overflow” section at the end of form since expanding that section will not affect the portion of the form which has been approved.
The problem
You need to capture the text entered into the form using an interactive Form Guide which is not limited to the restrictions of the form’s approved layout. As such, the Form Guide will capture the text in a single field and you need that text to be entered into the PDF version of the form. If you put all the text into the appropriate section on the form, it won’t fit and the text will be cut-off (e.g. it will not print entirely and you will miss some of the important information).
You need some way to automatically split that text between the small section in the form and the overflow section at the end of the form. In other words, you need to ensure that only the text that can fit within the small form section is placed there and the rest is placed in the overflow section at the end.
In Designer 8.2, the content of fields can now be split between pages however in this case, you can’t use this feature because the small form section can’t be expanded (it’s fixed in size).
The solution
This is the problem Stephanie, Glenn and I were faced with on a recent customer visit. Stephanie took the time to put this into a sample form which provides the script we wrote to handle this task. It’s basically a mini text parser written in JavaScript that splits text between two fields with a fixed-width font (e.g. Courier New, Lucida Console, etc.).

Is there some algorithm for variable font width to do the same split?
