Problems solved in this article: 1. Implement right-click menu function code; 2. Prevent the actual application of default events.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>右键菜单</title>
<style type="text/css">
#menu {
position: fixed;
left:0;
top:0;
width:200px;
height: 400px;
background-color: blue;
display: none;
}
</style>
</head>
<body>
<div id="menu">
</div>
<script type="text/javascript">
var menu = document.getElementById("menu");
document.oncontextmenu = function(e) {
var e = e || window.event;
//鼠标点的坐标
var oX = e.clientX;
var oY = e.clientY;
//菜单出现后的位置
menu.style.display = "block";
menu.style.left = oX + "px";
menu.style.top = oY + "px";
//阻止浏览器默认事件
return false;//一般点击右键会出现浏览器默认的右键菜单，写了这句代码就可以阻止该默认事件。
}
document.onclick = function(e) {
var e = e || window.event;
menu.style.display = "none"
}
menu.onclick = function(e) {
var e = e || window.event;
e.cancelBubble = true;
}
// document.addEventListener("contextmenu",function(e){
// var e = e || window.event;
// e.preventDefault();
// alert("menu");
// },false)
</script>
</body>
