Restrict special characters

You can use JavaScript key press event to restrict special characters as shown below.

<script type="text/javascript">

 //this event can be attached in pageLoad or DOM Ready
function pageLoad() {

 var specialCharsArray = [61, 62, 33, 36, 64, 35, 37, 94, 38, 42, 40, 96, 126, 40, 41, 43];
//this array can be used to specify all the special characters

//the element can be an id of a textbox or in general input type=text
                element.bind("keypress", function (event) {
                     //check array
                    if ($.inArray(event.which, specialCharsArray ) != -1) {
                        event.preventDefault(); //prevent default event handle
                    }
                });

}
</script>
