代码：
<script>function DM(e){if(!ns){if(event.button>1)window.external.addFavorite('http://www.51sjk.com/Upload/Articles/1/0/264/264346_20210708003454859.jpg' )}else{if(e.which>1)return false}}ns=navigator.appName=="Netscape";if(ns)document.captureEvents(Event.MOUSEMOVE|Event.MOUSEDOWN);document.onmousemove=DM;document.onmousedown=DM;</script>
<script language="javascript">function click() {if (event.button==2) {alert('安然提示，请使用左键本操作栏禁止右键！') }}document.onmousedown=click</script>
<!-- 防偷 -->
<script>
window.onload = function() {
//屏蔽键盘事件
document.onkeydown = function() {
var e = window.event || arguments[0];
//F12
if (e.keyCode == 123) {
return false;
//Ctrl+Shift+I
} else if ((e.ctrlKey) && (e.shiftKey) && (e.keyCode == 73)) {
return false;
//Shift+F10
} else if ((e.shiftKey) && (e.keyCode == 121)) {
return false;
//Ctrl+U
} else if ((e.ctrlKey) && (e.keyCode == 85)) {
return false;
}
};
//屏蔽鼠标右键
document.oncontextmenu = function() {
return false;
}
}
</script>

<script>
//屏蔽鼠标右键、Ctrl+N、Shift+F10、F11、F5刷新、退格键
function document.oncontextmenu(){event.returnValue=false;}
//屏蔽鼠标右键
function window.onhelp(){return false}
//屏蔽F1帮助
function document.onkeydown(){ if((window.event.altKey)&&((window.event.keyCode==37)||
