js implements hexadecimal encoding of strings without encryption_javascript skills

Today I saw someone in the group asking a question about hexadecimal encoding, so I wrote a small program using JS to convert it. Remember: this is just encoding, not encryption!

Convert string to hexadecimal encoding:

Copy code The code is as follows:

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"));

Hexadecimal encoding to string:

Copy code The code is as follows:

str="x68x74x74x70x3ax2fx2fx77x77x77x2ex71x71x2ex63x6fx6d";
//Paste this string into the Chrome browser or FireBug console and press Enter to see the original string content.
