Is there a foolproof method for detecting Arabic input in a form before submission? Can Javascript effectively manage this task, or is it better handled by server-side scripts like .NET?
I propose implementing a script to immediately block users from entering Arabic characters into the form and display an alert message.
If you have any suggestions or examples on how to achieve this, please share your insights.
Thank you.
When working with Unicode, Arabic characters can be found within a specific range. To check if a string contains any of these characters in JavaScript, you can utilize a regular expression. (This can also be done in c#.) Check out this handy tool that allows you to choose the ranges you want to search for and generate a JS-compatible regex.
For instance, using [\u0600-\u06FF\u0750-\u077F] will identify characters falling within the Unicode ranges associated with "Arabic" and/or "Arabic Supplement".
One way to detect this is by utilizing the Google Ajax Language API. Check out this example.
