我这么写可以弹出click
<html>
<head>
</head>
<body>
<div id="myHeader">
This is a header
</div>
<script>
var click = function(){
alert("click")
}
var doc = document.getElementById("myHeader");
doc.addEventListener("click", click, false);
</script>
</body>
</html>
但是吧JS代码放到单独的test.JS文件里
<script type="text/javascript" src="test.js">
</script>
这样外联引用就不好使，请问为什么
应该没有问题的，下面代码在多个浏览器测试了
HTML code:
<input type="checkbox" />
<input type=button onclick="updatex()" value="字体"/>
<div id="myHeader">
This is a header
</div>
<script src="LinkHover.js" type="text/javascript">
</script>
