一、常用的滑鼠事件
<body>
<img src=https://www.cnblogs.com/ruigege0000/p/"img/img_05.png" alt="" width="250px">
<script>
window.onload = function (ev) {
var logo = document.getElementsByTagName("img")[0];
//1.新的事件
logo.onmouseover = function (e1) {
console.log("-----");//滑鼠進入圖片就會觸發,也就懸停在圖片上
this.setAttribute("src","img/img_02.png");
}
logo.onmouseleave = function (e2) {
this.setAttribute("src","img/img_05.png");//滑鼠離開圖片就會觸發
}
}
</script>
