此javascript的“ rel”应该是什么?

标签: javascript html css hyperlink rel

在预览中一切正常,但是当我在任何其他软件上运行它时,javascript都无法链接-我知道这是由于两件事:

  1. 无论是否链接了javascript,它都是完全一样的
  2. 它只是不执行其应做的工作-javascript的目的是使您单击菜单按钮时所有项目都掉下来,但在此未发生任何事情。

我尝试制作rel =“ script”,但这无济于事。

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';
		}
	}
}
* {box-sizing: border-box;max-width: 100%;font-family: 'Gruppo', cursive;}

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

<!-- 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:

<script src="main.js"></script>
  

HTML脚本元素用于嵌入或引用可执行代码;通常用于嵌入或引用JavaScript代码。
