对于这个 JavaScript,"rel" 应该是什么?

What should the "rel" be for this JavaScript?

在这里的预览中一切正常,但是当我在任何其他软件中使用 运行 时,JavaScript 却没有 link - 我知道这是因为两个事情:

  1. 不管有没有 JavaScript 被 linked
  2. 完全一样
  3. 它只是没有按预期执行 - JavaScript 旨在使当您单击菜单按钮时所有项目都出现,但是 none这正在这里发生。

我试过制作rel="script",但没有任何效果。

var open = false;

function Drop(n) {
 var i;
 if (open == false) {
  for (i = n; i < 5; i++) {
   Drp(i)
  }
  open = true
 } else if (open == true) {
  for (i = n; i < 5; i++) {
   Cls(i)
  }
  open = false
 }
}

function Drp(n) {
 var elem = document.getElementsByClassName("menu-con")[n];
 var pos = -1 * window.innerHeight - n * 100;
 var id = setInterval(frame, 5);

 function frame() {
  if (pos >= -10) {
   clearInterval(id);
   elem.style.top = 0 + 'px';
  } else {
   pos += 10;
   elem.style.top = pos + 'px';
  }
 }
}

function Cls(n) {
 var elems = document.getElementsByClassName("menu-con")[n];
 var poss = 0;
 var ids = setInterval(frames, 5);

 function frames() {
  if (poss <= -1 * window.innerHeight) {
   clearInterval(ids);
   elems.style.top = -1 * window.innerHeight + 'px';
  } else {
   poss += -7 - n * 2;
   elems.style.top = poss + 'px';
  }
 }
}

您可以通过以下方式包含 JavaScript 文件 - 这些示例展示了如何在 HTML4 和 HTML5 中使用 <script> 元素导入脚本(Script element - Basic usage):

<!-- HTML4 -->
<script type="text/javascript" src="javascript.js"></script>

<!-- HTML5 -->
<script src="main.js"></script>

我的建议是使用以下 HTML5 一个:

<script src="main.js"></script>

The HTML script element is used to embed or reference executable code; this is typically used to embed or refer to JavaScript code.

要包含 js,您必须使用

<script type="text/javascript" src="main.js"></script>
