    function CheckEnglishOnly(field)
    {
        var sNewVal = "";
        var sFieldVal = field.value;

        for(var i = 0; i < sFieldVal.length; i++) {

            var ch = sFieldVal.charAt(i);

            var c = ch.charCodeAt(0);

            if(c < 0 || c > 255) {
                // Discard
            }
            else {
                sNewVal += ch;
            }
        }

        field.value = sNewVal;
    }

    function CheckArabicOnly(field)
    {     
        var sNewVal = "";
        var sFieldVal = field.value;

        for(var i = 0; i < sFieldVal.length; i++) {

            var ch = sFieldVal.charAt(i);
            var c = ch.charCodeAt(0);

            if(c < 1536 || c > 1791) {
                // Discard

            }
            else {
                sNewVal += ch;
               $( "#txtArabic" ).focus(); 
            }
        }

        field.value = sNewVal;
    }

    </script>
</head>
<body>

Arabic Only (onchange): <input type="text" id="txtArabic" if(onkeyup) { onkeyup="CheckArabicOnly(this);" }  elseif(onpaste) { onkeyup="CheckArabicOnly(this);" }/><br />
</body>
</html>
