Filtering input text with jQuery
I want to filter and block text input. For example, in some cases, the user can only enter Persian / Farsi characters but not English, or when the user can enter English but not Persian. So some input only accepts Persian / Farsi characters, while others only accept English.
Also I found this http://www.thimbleopensource.com/tutorials-snippets/jquery-plugin-filter-text-input . If you know any regular checkout for Persian characters can help me or how to change keyboard mode.
thank.

According to the Unicode character list , you need to check for characters in the Unicode range U+0600-U+06FF
.
So, if you want to prevent any other unicode character from being inserted, you can simply check your input value against a /^[\u0600-\u06FF]+$/g
regex. Also note that there are many Unicode ranges you can allow. On the Arabic Unicode Encoding page , next to Arabic (0600-06FF, 225 characters) you have
- Arabic application (0750-077F, 48 characters)
- Arabic Extended-A (08A0-08FF, 39 characters)
- Arabic Presentation Form-A (FB50-FDFF, 608 characters)
- Arabic Presentation Form-B (FE70-FEFF, 140 characters)
- Rumi Numeral Symbols (10E60-10E7F, 31 characters)
- Arabic mathematical alphabetic characters (1EE00-1EEFF, 143 characters)
in this case add as many times as you need in the expression:
for example/^[\u0600-\u06FF\u0750-\077F\u0...]+$/g
So, using the mentioned snippet you should write
$('#text_input').filter_input({regex:'[\u0600-\u06FF\u0750-\077F\u0...]'});
Hope this helps. السلام عليكم
