字符串转16进制

function strToHexCharCode(str) {

if(str === "")

return "";

var hexCharCode = [];

hexCharCode.push("0x");

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

hexCharCode.push((str.charCodeAt(i)).toString(16));

}

return hexCharCode.join("");

}

16进制转字符串

function hexCharCodeToStr(hexCharCodeStr) {

var trimedStr = hexCharCodeStr.trim();

var rawStr =

trimedStr.substr(0,2).toLowerCase() === "0x"

?

trimedStr.substr(2)

:

trimedStr;

var len = rawStr.length;

if(len % 2 !== 0) {

alert("Illegal Format ASCII Code!");

return "";

}

var curCharCode;

var resultStr = [];

for(var i = 0; i < len;i = i + 2) {

curCharCode = parseInt(rawStr.substr(i, 2), 16); // ASCII Code Value

resultStr.push(String.fromCharCode(curCharCode));

}

return resultStr.join("");

}
