jquery实现图片跟随鼠标的实例
开发后台写页面困难的一比啊，想写个鼠标移动某连接右侧显示二维码，并跟随鼠标移动的功能，各种查资料，花了一小天终于搞出来了，代码的记下来，浪费了我这么多时间，记你一辈子，这个可以直接在W3School直接运行，可以根据某行显示某个特定的图片，自己定义就行
实现代码：
<html>
<head>
<script src="https://cdn.zhanzhang360.cn/imgupload/007102/jquery.js"></script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>jquery图片跟随鼠标</title>
<script type="text/javascript">
function hideImg(num){
if(num.className == "1_name"){
$('#1_erweima').hide();
}else if(num.className == "2_name"){
$('#2_erweima').hide();
}
}
function showImg(num) {
var intX = window.event.clientX;
var intY = window.event.clientY;
if (num.className == "1_name") {
$('#1_erweima').css("left", intX + 20 + "px");
$('#1_erweima').css("top", intY + 10 + "px");
$('#1_erweima').show();
} else if (num.className == "2_name") {
$('#2_erweima').css("left", intX + 20 + "px");
$('#2_erweima').css("top", intY + 10 + "px");
$('#2_erweima').show();
}
}
</script>
</head>
