Step 0. Customize settings
Set ShowChangeLangButton, KeyBoardError, ChangeDir variables values with your own opinon!
ShowChangeLangButton // Show Change Language Button --> 0: Show / 1: Visible
KeyBoardError // the action when useres keyboard is farsi --> 0: Disable FarsiType / 1: Show Error
ChangeDir // change the input or textarea direction when language is change --> 0: No Action / 1: Change direction / 2: set Rtl/Ltr button
Step 1.
Include the "farsitype.js" file to your HTML part (before ):
Step 2.
Add "lang" attribute with value "fa" to any or
[Magic : only the lang="fa" is important for FarsiType!]
[As ver 1.2.1 , you can also use lang="fa-IR"]
Step 3. (OPTIONAL)
You can also add an enable/disable checkbox beside your form.
Note : You can use F8 keybord button to switch languages instead of using the change language button.
