我正在尝试创建一个可以使用 JavaScript 将文本转换为二进制的基本网站，但我真的不知道如何使按钮Convert!工作。有人有我可以使用的简单修复方法吗？（别介意 CSS 缺少一些代码，我还没说完。）function convert() { const input_el = document.querySelector(".input-text"); const output_el = document.querySelector(".output-binary"); input_el.addEventListener("input", (event) => { let input_text = event.target.value; let output_arr = []; for (var i = 0; i < input_text.length; i++) { output_arr.push(input_text.charCodeAt(i).toString(2)); } output_el.innerHTML = output_arr.join(" "); });}body { margin: 0; padding: 0;}header { padding: 30px; background: #09A954; color: white; text-align: center; font-family: arial; font-size: 30px;}.navbar { padding: 12px; background: #363636; color: white; font-size: 15px;}.container { display: flex; flex-direction: column; padding: 80px; background: #B3B3B3;}.input_box { display: flex; flex-direction: column; justify-content: center; align-items: center; padding: 40px; background: #D35400; border-radius: 10px; text-align: center; box-shadow: 0px 3px 5px #000000; height: 100px; width: ;}input { background: #D35400; border: none; border-bottom: 2px solid #000000; font-size: 15px;}button { width: 100px;}.output_box { display: flex; flex-direction: column; justify-content: center; align-items: center; padding: 40px; background: #2980B9; border-radius: 10px; text-align: center; box-shadow: 0px 3px 5px #000000; height: 100px; width: ;}p2 { font-size: 30px; font-family: calibri;}p4 { font-size: 15px; font-family: arial;}链接到 JSFiddle：https://jsfiddle.net/SaltySandwich/65te8omy/

我修复了您现有的项目。
我对 JavaScript 采取了一种更简单的方法。您可以在 JavaScript 代码上用 6 行编写您需要的所有内容:)
对于您的输出，您应该使用<output>代替<input>.
看看这个：
function convert() {
var output = document.getElementById("output_text");
var input = document.getElementById("input_text").value;
output.value = "";
for (i = 0; i < input.length; i++) {
output.value += input[i].charCodeAt(0).toString(2) + " ";
}
}
body {
margin: 0;
padding: 0;
}
header {
padding: 30px;
background: #09A954;
color: white;
text-align: center;
font-family: arial;
font-size: 30px;
}
.navbar {
padding: 12px;
background: #363636;
color: white;
font-size: 15px;
}
.container {
display: flex;
flex-direction: column;
padding: 80px;
background: #B3B3B3;
}
.input_box {
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
padding: 40px;
background: #D35400;
border-radius: 10px;
text-align: center;
box-shadow: 0px 3px 5px #000000;
height: 100px;
width: ;
}
input {
background: #D35400;
border: none;
border-bottom: 2px solid #000000;
font-size: 15px;
}
input:focus {
border: none;
border-bottom: 2px solid #000000;
font-size: 15px;
outline: none;
}
button {
width: 100px;
}
.output_box {
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
padding: 40px;
background: #2980B9;
border-radius: 10px;
text-align: center;
box-shadow: 0px 3px 5px #000000;
height: 100px;
width: ;
}
p2 {
font-size: 30px;
font-family: calibri;
}
p4 {
font-size: 15px;
font-family: arial;
}

<p2>This is what a human sees:</p2><br>
<p3>Please enter text below</p3><br>
<!--INPUT FIELD-->
<input id="input_text" value="Human sees this" />
</div><br><br>
<button onclick="convert()">Convert!</button><br><br>
<div class="output_box">
<p2>This is what a machine sees:</p2><br>
<!--INPUT FIELD-->
<output id="output_text">

哦..我还稍微编辑了你的CSS，这样输入周围就没有烦人的边框了...你可以通过删除以下内容来删除我的更改：
input:focus {
border: none;
border-bottom: 2px solid #000000;
font-size: 15px;
outline: none;
}
如果您需要清除任何内容，请务必在这篇文章下发表评论:)

看看这个：
function convert() {
var output=document.getElementById("ti2");
var input=document.getElementById("ti1").value;
output.value = "";
for (i=0; i < input.length; i++) {
output.value +=input[i].charCodeAt(0).toString(2) + " ";
}
}
input {font-size:12px; width:200px;}
<!DOCTYPE html>

<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

<meta name="description" content="">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="">

<body>
<input id="ti1" value ="Human sees this"/>
<input id="ti2" value ="Machine sees this"/>
<button onclick="convert();">Convert!</button>
<script src="main.js"></script>
</body>
</html>
它应该给你基本的想法......
