Implementing Digits restriction Using JQuery

Hi Sir

I have following field in my html form :

<div>Age<input type="text" name="quantity" id="quantity" /></div>

I want to implement two things :

1 if the letter is not digit then display error and don't type anything

2 Age must be between 18 & 35 and it will show error when it is not in between age range.

Please provide code.

You can implement these two things using ASCII code & parseint method. Code is provided below :

//called when key is pressed in textbox
    $("#quantity").keypress(function (e)  
    { 
    $("#errmsg").hide();
      //if the letter is not digit then display error and don't type anything
      if( e.which!=8 && e.which!=0 && (e.which<48 || e.which>57))
      {
        //display error message
        $("#errmsg").html("&nbsp;&nbsp;Digits Only").show(); 
       return false;
      } 
      });
      $('#quantity').blur(function(a) {
      if((parseInt($("#quantity").val(), 10)<18)) 
      {
      $("#errmsg").html("&nbsp;&nbsp;Age must be greater than 18").show(); 

      }
      if((parseInt($("#quantity").val(), 10)>35)) 
      {
      $("#errmsg").html("&nbsp;&nbsp;Age must be less than 35").show(); 
      }
     });
