utf16EncodeDecode.js
// js 里 \x 开头的通常是16进制编码的数据，下面代码实现编解码：
// 解码
//eg.
//decode('\x5f\x63\x68\x61\x6e\x67\x65\x49\x74\x65\x6d\x43\x72\x6f\x73\x73\x4c\x61\x79\x65\x72')
//"_changeItemCrossLayer"
function decode(str){
return str.replace(/\\x(\w{2})/g,function(_,$1){ return String.fromCharCode(parseInt($1,16)) });
}
//编码
//eg.
//encode("_changeItemCrossLayer")
//"\x5f\x63\x68\x61\x6e\x67\x65\x49\x74\x65\x6d\x43\x72\x6f\x73\x73\x4c\x61\x79\x65\x72"
function encode(str){
return str.replace(/(\w)/g,function(_,$1){ return "\\x"+ $1.charCodeAt(0).toString(16) });
