I started working on a solution via [JSFiddle here](https://jsfiddle.net/5L3jbv41/3/), I hope this helps! — Nick, Oct 08 '17 at 14:47
@snapjs hyphens are behind the 09 when typing and also i want 09 is unchangeable.please help tnx — sepehr, Oct 08 '17 at 17:13
@sepehr I think I'm just misunderstanding what you're looking for. What would an example of a final number look like? — Nick, Oct 08 '17 at 17:39
@snapjs i want to first of all . that textbox look like 09--------- . 09 is constant and unchangebale.and when i start typing numbers in textbox numbers replaces with hyphens one by one in front of 09 — sepehr, Oct 08 '17 at 17:47
OK, so it first appears as 09--------. Then, when someone starts typing, let's say they type 1, would it look like 091--------? Also, would a final number look like 09123456789? — Nick, Oct 08 '17 at 18:11
@snapjs exactly . would you tell me what is the code for that? — sepehr, Oct 08 '17 at 18:18

I believe the following code takes into account all of the requirements. Additionally, this can be viewed in action in JSFiddle here.

$("#PhoneField").val("09---------");

$("#PhoneField").keyup(function () {
  $("#PhoneField").val(function() {
      var phoneNumber = $(this).val().replace(/-/g, "");
      var curLength = phoneNumber.length;
      // Add correct number of hyphens to front of phone number
      var hyphens = Math.max(12 - phoneNumber.length, 0);
      phoneNumber = phoneNumber + Array(hyphens).join("-");
      // If the first characters are not 09, add them
      if(phoneNumber.substring(0, 2) !== "09") {
        phoneNumber = "09" + phoneNumber;
      }
      // Impose length limit
      phoneNumber = phoneNumber.substring(0,11);
      return phoneNumber;
  });
});
