This functions is for jQuery. It permits only numbers to textboxes The Code:

jQuery.fn.filter = function() {
    $(this).keydown(function (e) {
        if (e.shiftKey || e.ctrlKey || e.altKey) { // if shift, ctrl or alt keys held down
            e.preventDefault();         // Prevent character input
        } else {
            var n = e.keyCode;
            if (!((n == 8)              // backspace
            || (n == 46)                // delete
            || (n >= 35 && n <= 40)     // arrow keys/home/end
            || (n >= 48 && n <= 57)     // numbers on keyboard
            || (n >= 96 && n <= 105))   // number on keypad
            ) {
                e.preventDefault();     // Prevent character input
            }
        }
  $(document).mousedown(function(e){ 
    if( e.button == 2 ) { 
      e.preventDefault();         // Prevent character input
        } else {
            var n = e.keyCode;
            if (!((n == 8)              // backspace
            || (n == 46)                // delete
            || (n >= 35 && n <= 40)     // arrow keys/home/end
            || (n >= 48 && n <= 57)     // numbers on keyboard
            || (n >= 96 && n <= 105))   // number on keypad
            ) {
                e.preventDefault();
