jquery禁用右键单击、F5刷新

1、禁用右键单击功能

$(document).ready(function() {
       $(document).bind("contextmenu",function(e) {				 
	    alert("sorry! No right-clicking!");
	    return false;
       });
});

2、屏蔽F5刷新

$(document).ready(function() {
	$(document).bind("keydown",function(e){   
	        e=window.event||e;
	        if(e.keyCode==116){
		        e.keyCode = 0;
		        return false; 
	        }
        });	
});
