Typing and displaying percentages in a form

Question

Using Acrobat 9, I have some form fields that are set up to display percentages. The percentages are typed in by the user, not calculated. For example, if the user wants 20%, they have to type .20 in the field.
My question -- is there a way to set up the form field so that the user can type in 20, for example when they want 20%, instead of .20 (point two zero)?

Answer 1

Add the following two functions to a document-level JavaScript:
// Document-level JavaScript code
function percent_Format() {
    // Format for numeric, 2 decimal points
    AFNumber_Format(2, 0, 0, 0, "", false);
    // Add a percent character on the end if the field is not blank
    if (event.value) event.value += "%";
function percent_Keystroke() {
    // Format for numeric, 2 decimal points
    AFNumber_Keystroke(2, 0, 0, 0, "", false);
Then call the first in the field's Format event like this:
// Custom Format script
percent_Format();
And the second in the field's Keystroke event like this:
// Custom Keystroke script
percent_Keystroke();
