Writing a Javascript for a percent entry on a form....

Hopefully, someone can help me.  I created a form in Acrobat.  I set up one of the lines to enter as a percentage.  The issue is when I enter (for example 50 thinking it would be 50% it shows as 5,000%.)  I realize i could enter .50 and have it show up correctly.  I am not familiar with Javascripting, but I believe a script can be written so what ever is entered will show up correctly.  If I enter a 5 then it would show 5% etc.  Does anyone know how to write this?

I would greatly appreciate your help!!

Sincerely,

Steve

Do not use the built in Format, select Custom on the Format tab and enter this script into the custom formatting box.

if(!/^\s*$/.test(event.value) && !isNaN(event.value)) event.value += "%";

This takes care of adding the % symbol, Now enter this code into the Keystroke script to prevent the user from entering non-numbers.

AFNumber_Keystroke(2, 0, 0, 0, "", true);

After this the display will revert to showing you entered a number format, but is will work the way you want

    That's how Percent fields work. Their value ranges from 0 (0%) to 1 (100%). If you want it to work differently you would need to write your own keystroke, validation and format scripts.
