Allow only Persian (Arabic) characters in TextBox using JavaScript

This is JavaScript and not database saving code, explain in detail exactly what is getting saved in database with a screenshot

hi

I want in database save english alphabet and persian alphabet and I want it doesn't save any other character like  ()!@##$^&*

(so that javascript code doesn't allow users enter other character into TEXTBOX)

now in javascript code that you gave me in other threads it allow users enter  English Alphabet and does't allow users that enter persian alphabet 

in this script code is  English Alphabet ascii code that allow users enter english alphabet 

 ret = ((keyCode >= 48 && keyCode <= 57) || (keyCode >= 65 && keyCode <= 90)

now I want change code that allow users that can enter persian alphabet like english alphabet

so I put persian alphabet ascii code in my threads and and hope you can help me 

I think I should define that persian ascii code into javascrtipt code untill allow users to enter persian alphabet...

but I don't know how I can do it...

For that you need to first find the ASCII code for Persian characters without that it is not possible.

And since keyboard can either be Persian or English you need, the code can work only for one language and not both
