.replace doesn't work

Question

I wrote this code to replace some chars in a string:

$(".rtl:not(.num)").keypress(function(e)
 { var key = (e.keyCode || e.which);
   var vlu = $(this).val();
   var charTyped = String.fromCharCode(key);

   if (charTyped=='ك') 
    { vlu.replace(/ك/g,'ک'); 
      alert("keh"); }

   if (charTyped=='ي') 
    { vlu.replace(/ي/g,'ی'); 
      alert("yeh"); }

   alert(vlu); 
 });

After the code executes, vlu has not changed. What is wrong?

Do you mean `alert(vlu);` doesn't display replaced string value or that the original `$(this).val()` isn't updated? — A. Wolff, May 16 '15 at 13:29

Replace does not change the original string, it returns a new string.

MDN String replace()

var str = "abc123";
var updated = str.replace("123","");
console.log("str: ", str);
console.log("updated: ", updated);
