代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style>
html, body {
margin: 0;
padding: 0;
}
ul {
40px;
list-style: none;
display: inline-block;
margin: 0;
padding: 0;
position: fixed;
}
ul li {
padding-left: 10px;
line-height: 20px;
background: greenyellow;
}
</style>
</head>
<body>
<ul id="customList">
<li>11</li>
<li>22</li>
<li>33</li>
</ul>
</body>
<script>
document.oncontextmenu= function(event){
var e= event || window.event;
e.preventDefault? e.preventDefault():e.returnValue= false;
var customList= document.getElementById("customList");
customList.style.left= e.clientX+ "px";
customList.style.top= e.clientY+ "px";
}
</script>
</html>
解析:
document.oncontextmenu: oncontextmenu方法在目标元素上右键时触发，兼容性良好
var e= event || window.event;
e.preventDefault? e.preventDefault():e.returnValue= false;
兼容IE并阻止默认行为
customList.style.left= e.clientX+ "px";
customList.style.top= e.clientY+ "px";
