方法一：有弊端但代碼簡單
當拖動右鍵的時候不能屏蔽
全屏的時候不能屏蔽
<body ondragstart="return false" oncontextmenu="return false" onselectstart="return false">
方法二：完全屏蔽，重新定義右鍵內容
<!DOCTYPE HTML> <html id="myDiv"> <head> <meta charset="UTF-8"/> <title>DOM3 event textInput</title> <style type="text/css"> #myMenu{ position: absolute; background: #eee; list-style: none; visibility: hidden; } </style> </head> <body> <ul id="myMenu"> <!-- <li><a href="http://www.baidu.com">百度</a></li> --> </ul> <script type="text/javascript"> window.onload = function(){ document.getElementById('myDiv').addEventListener('contextmenu',function(e){ e.preventDefault();//取消瀏覽器默認行爲，以保證不顯示瀏覽器默認的上下文菜單 var menu = document.getElementById('myMenu'); menu.style.left = e.clientX+"px"; menu.style.top = e.clientY+"px"; menu.style.visibility = 'visible'; },false); document.addEventListener('click',function(){ var menu = document.getElementById('myMenu'); menu.style.left = "0px"; menu.style.top = "0px"; menu.style.visibility = 'hidden'; },false); } </script> </body> </html>
