Try this $(document).ready( function () { //called when key is pressed in textbox $( "#quantity" ).keypress( function (e) { //if the letter is not digit then display error and don't type anything if (e.which != 8 && e.which != 0 && (e.which 57)) { //display error message $( "#errmsg" ).html( "Digits Only" ).show().fadeOut( "slow" ); return false ; } }); });
