javascript - 使用 JavaScript 将二进制文件转换为文本

Question

如何使用 JavaScript 将二进制代码转换为文本？我已经将文本转换为二进制，但有没有办法反过来做？

这是我的代码:

function convertBinary() {
  var output = document.getElementById("outputBinary");
  var input = document.getElementById("inputBinary").value;
  output.value = "";
  for (i = 0; i < input.length; i++) {
    var e = input[i].charCodeAt(0);
    var s = "";
    do {
      var a = e % 2;
      e = (e - a) / 2;
      s = a + s;
    } while (e != 0);
    while (s.length < 8) {
      s = "0" + s;
    }
    output.value += s;
  }
}

<div class="container">
  <span class="main">Binary Converter</span><br>
  <textarea autofocus class="inputBinary" id="inputBinary" onKeyUp="convertBinary()"></textarea>
  <textarea class="outputBinary" id="outputBinary" readonly></textarea>
  <div class="about">Made by <strong>Omar</strong></div>
</div>

我最近使用 for 循环完成了这方面的练习。希望有用:

function binaryAgent(str) {

var newBin = str.split(" ");
var binCode = [];

for (i = 0; i < newBin.length; i++) {
    binCode.push(String.fromCharCode(parseInt(newBin[i], 2)));
  }
return binCode.join("");
}
binaryAgent('01000001 01110010 01100101 01101110 00100111 01110100');
//translates to "Aren't"

编辑:在学习了更多 JavaScript 之后，我能够缩短解决方案:

function binaryAgent(str) {

var binString = '';

str.split(' ').map(function(bin) {
    binString += String.fromCharCode(parseInt(bin, 2));
  });
return binString;
}
binaryAgent('01000001 01110010 01100101 01101110 00100111 01110100');
//translates to "Aren't"
