js中禁用右键菜单

JQUERY实现：

<script type="text/javascript" src="./js/jquery-1.7.1.js"></script>
<script type="text/javascript">
	$(document).ready(function(){
	    $(document).bind("contextmenu",function(e){
	        return false;
	    });
	});
</script>

 

js判断：

<script type="text/javascript">
	document.onkeydown = function() {
		if (event.keyCode == 116) {
			event.keyCode = 0;
			event.returnValue = false;
		}
	}
	document.oncontextmenu = function() {
		alert("禁止右键！");
		event.returnValue = false;
	}
</script>
