Question

我想制作各种文本解析器，我已经做了很多研究。

我想知道我是否正确使用了javascript。我知道你不应该在js中创建文本解析器，但它是我所知道的唯一脚本语言。

到目前为止，这是我的代码：

<script>
  function makeCode() {
    for (i = 0; i < userCode.length; i++) {
    if (userCode.substring("print:"(0, 6)) {
      document.write(usercode.substring("print:"(6,0));
  }
</script>

<style>
  p {
    text-align: center;
    color: #cc0000;
  }
  h1 {
    text-align: center;
    font-family: Impact;
    color: #cc0000;
  }
  body { 
    text-align: center;
  }
  form {
    text-align: center;
  }
</style>
<h1>NCPL</h1>
<p style="font-size: 10px">In Browser NinjaCorp Programming Language Editor</p>
</head>
<body>
<form name="userCode">
    <textarea id="userCode" name="userCode" cols="80" rows="20" placeholder="Type your code     here"></textarea></br>
    <a href="javascript:makeCode()"><button type="button">Run Code!</button></a>
</form>

这是您要找的吗？

function makeBode() {
    var userCode = document.getElementById('userCode').value;
    var myDiv = document.getElementById('myDiv');
  
     // alert(userCode)
    for (i = 0; i < userCode.length; i++) {
       myDiv.innerHTML =  myDiv.innerHTML  + userCode.substring((i,i+6)) +'<br>'; 
    }

}

p {
    text-align: center;
    color: #cc0000;
  }
  h1 {
    text-align: center;
    font-family: Impact;
    color: #cc0000;
  }
  body { 
    text-align: center;
  }
  form {
    text-align: center;
  }

<div id="myDiv"></div>

<h1>NCPL</h1>
<p style="font-size: 10px">In Browser NinjaCorp Programming Language Editor</p>
</head>
<body>
  
<form name="userCode">
    <textarea id="userCode" name="userCode" cols="80" rows="20" placeholder="Type your code     here">Typing here so there is some text to work with </textarea></br>
    <a href="javascript:makeBode();"><button type="button">Run Code!</button></a>
  
</form>
