<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>HTML事件</title>
</head>
<body>
<!-- 此处写代码 -->
<input type="button" value="开始" onmousemove="startFn(this,'purple')" onmouseout="startFn(this,'gray')"/>
<input type="button" value="结束" onmousemove="endFn(this,'yellow')" onmouseout="startFn(this,'gray')"/>
<!-- onmousemove和 onmouseover的区别-->
<script>
function startFn(btn,color){
//console.log(btn)
btn.style.color=color
};
function endFn(btn,color){
btn.style.color=color
}
</script>
</body>
</html>

好像它们的效果一样
