JS字符串二进制相互转换：
function strToBinary(str){
var result = [];
var list = str.split("");
for(var i=0;i<list.length;i++){
if(i != 0){
result.push(" ");
}
var item = list[i];
var binaryStr = item.charCodeAt().toString(2);
result.push(binaryStr);
}
return result.join("");
}
function binaryToStr(str){
var result = [];
var list = str.split(" ");
for(var i=0;i<list.length;i++){
var item = list[i];
var asciiCode = parseInt(item,2);
var charValue = String.fromCharCode(asciiCode);
result.push(charValue);
}
return result.join("");
}
console.log(strToBinary("测试")) // 110110101001011 1000101111010101
console.log(binaryToStr("110110101001011 1000101111010101")) // 测试
