try this  and attach the function to the textfield

function restrictChars(e) {
        var intKey;
        var restrictedKeys = new Array();
        
        //Set your restricted keyCodes from the URL I gave you
        restrictedKeys[0] = 8
        restrictedKeys[1] = 20
 
        if(window.Event)
            intKey = e.which;
        else
            intKey = e.KeyCode;
 
        for(var i = 0; i < restrictedKeys.length; i++) {
            if(intKey == restrictedKeys[i])
                e.returnValue = false;
            else {
                // Here is a sample check for numerics
                if(intKey > 47 && intKey < 58) {
                    // They pressed a number;
                    e.returnValue = false;
                }
            }
        }
    }
