How to limit the character entry into a text box in jQuery?

Hi All,
        I had come across a situation where i need to limit the character count into a text box. Suppose, your there is a requirement where the text box should take only 20 characters.


In this situation preferably use the keypress method for even to happen as follows

$('#IdOfTheTextBox’).keypress(function (e) {
              if (e.which < 0x20) {
//This snippet you have to use , otherwise it will not allow you perform action using  backspace or delete button on FireFox
                     return;
              }
              if (this.value.length == "20") {
                     e.preventDefault();
              }
              });

By doing above, it will not allow you to enter characters after 20the character.

Hope this will help .
cheers
