Try this code:

$("#txtn").on('change keyup paste keydown', function(e) {        
    if(just_persian(e.key) === false)
        e.preventDefault();
});


function just_persian(str) {
   var p = /^[\u0600-\u06FF\s]+$/;
   if (!p.test(str)) {
       return false
   }
   return true;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="txtn">

I hope this work :)

Thanks for the helping but now i want to also add Passport number validation and National Id validation for iran so any idea about it this?? – coderwill May 01 '17 at 06:02
Additional to checking Persian characters? – Yashar Aliabbasi May 01 '17 at 06:06
that mean i can't understand can you please let me know how can do that??Passport number is for indian and iranian for nationalid – coderwill May 01 '17 at 06:08
You can achieve to that goal with masked input – Yashar Aliabbasi May 01 '17 at 06:15
For passport i am used this regx string "[A-Z]{2}[0-9]{7}". – coderwill May 01 '17 at 06:16
@coderwill This two regex is opposite to each other. WIth first regex you wanna enter Persian characters only and with second one you wanna have English characters allowed in your input! – Yashar Aliabbasi May 01 '17 at 06:22
can you please suggest the "012-345678-9" this number who string regex is used?? and how can validate this number using java script – coderwill May 01 '17 at 06:28

If you would like to keep most of the code as it is, I would suggest checking that the name is not empty before validating and checking on the keyup event, after the character is available. Otherwise, the validation fails because the regex requires at least one character. Please note @yashar-aliabasi has a good answer because the validation will also run on pasting and the textbox triggering a change event as well as preventing invalid characters from entering the textbox.

function text(name)
{
    var name = $(name).val();
    if (name.length > 0) {
     just_persian(name);
    }
}

 function just_persian(str) {
    var p = /^[\u0600-\u06FF\s]+$/;
    if (!p.test(str)) {
        alert("not format");
    }
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="txtn" onkeyup="text(this)" value="">

Hello can you help me for that national id validation for iran? — coderwill, May 01 '17 at 07:24
I can try! Is the current regex `[A-Z]{2}[0-9]{7}` causing problems? What requirements is it not meeting? Do you have another question open for the id validation at the moment? — bnp887, May 01 '17 at 10:49

Try this code:

    document.getElementById('nameFa').addEventListener('keypress',function(e){

         if ((e.charCode >= 97 && e.charCode <= 122) || (e.charCode>=65 && e.charCode<=90)){
            alert("Language is english");
            e.preventDefault();
        }

        else if(isPersian(e.key))
             alert("Language is Persian");
        else
             alert("Others");
    });

    function isPersian(str){
        var p = /^[\u0600-\u06FF\s]+$/;
        return p.test(str);
    }

And

    <input type="text" id="nameFa">
