js byte数据转16进制

console.info(Bytes2Str([16,66,108,-27,2,-108]))

	function Bytes2Str(arrBytes){
		var str = "";
		for (var i = 0; i < arrBytes.length; i++) {
			var tmp;
			var num = arrBytes[i];
			if (num < 0) {
				//此处填坑，当byte因为符合位导致数值为负时候，需要对数据进行处理
				tmp = (255 + num + 1).toString(16);
			} else {
				tmp = num.toString(16);
			}
			if (tmp.length == 1) {
				tmp = "0" + tmp;
			}
			if(i>0){
				str += ":"+tmp;
			}else{
				str += tmp;
			}
		}
		return str;
