JS编码与解码（一）
[html]<html>
<body>
<script type = "text/javascript">
function encodeAll(str) {//转化为十六进制
var HEX = "0123456789ABCDEF",
radix = 16,
len = str.length,
encodeStr = "";
for (var i = 0; i < len; i++) {
var num = parseInt(str.charCodeAt(i), 10);
encodeStr += "%" + Math.floor(num / radix) + HEX.charAt(num % radix);
}
return encodeStr;
}
function decodeAll(encodeStr) {//把十六进制还原为字符串
var arr = encodeStr.split("%"),
str = ""; www.zzzyk.com
for (var i = 1; arr[i]; i++) {
str += String.fromCharCode(parseInt(arr[i], 16));
}
return str;
}
//测试代码
var s = "*!+abcdefgikzf!~@#$%^&*()_+";
s = encodeAll(s);
document.write(s + "<br/> " + decodeAll(s));
</script>
</body>
</html>
//以后会完善其可配置。
