How to Prevent input text from accepting any characters other than Arabic and Numeric using regular expressions ?

To Prevent input text from accepting any characters other than Arabic and Numeric using regular expressions in MVC, you should follow the below steps:

  1. Navigate to the _Layout.cshtml file .
  2. Add the <script></script> tags below.

MVC Text Box allow only Arabic characters using FrontEnd

  1. Open _Layout.cshtml file
  2. Add the <script></script> tags below

      $(".arabic-numeric").on("input", function () {
         var inputValue = $(this).val();
         var validChars = /^[0-9\u0600-\u06FF\s]+$/;
    
         if (!validChars.test(inputValue)) {
             // Remove invalid characters
             $(this).val(inputValue.replace(/[^0-9\u0600-\u06FF\s]+/g, ''));
         }
     });
    
  3. Add arabic-numeric class to any input type to allow only Arabic character and Numeric

          <div class="mb-3 col-xs-12 col-sm-6 col-md-6 col-lg-6">
           @Html.Label("Resource.Label.JobTitle", new { @class = " form-label", @for = "Position" })
           <span style="color: red;">*</span>
           @Html.TextBoxFor(m => m.Position, new { @class = "form-control arabic-numeric", @maxlength = "250" })
           @Html.ValidationMessageFor(Model => Model.Position, null, new { @class = "text-danger" })
          </div>
    

MVC Text Box allow only Arabic characters and Numeric using BackEnd

  1. Open your ViewModel class file
  2. Add the public string Position { get; set; } into ViewModel Class
  3. Add RegularExpression above property allow only Arabic character and Numeric

           [RegularExpression(@"^[0-9\u0600-\u06FF\s]+$", ErrorMessage ="Arabic and Numeric")]
           public string Position { get; set; }
    

Result :

If you don’t ask, the answer is always NO!
