今天看到群里有人提问关于十六进制编码的问题，所以使用JS写了个小程序转换一下，记住：这只是编码，不是加密！

字符串转十六进制编码：

复制代码 代码如下:

str="http://www.qq.com";
len=str.length;
arr=[];
for(var i=0;iarr.push(str.charCodeAt(i).toString(16));
}
console.log("\\x"+arr.join("\\x"));

十六进制编码转字符串：
复制代码 代码如下:

str="\x68\x74\x74\x70\x3a\x2f\x2f\x77\x77\x77\x2e\x71\x71\x2e\x63\x6f\x6d";
//将此字符串粘贴到Chrome浏览器或者FireBug的控制台回车即可看到原本的字符串内容。
