可以循环计时，而对于页面刷新，我们可以屏蔽鼠标右键、Ctrl+N、Shift+F10、Alt+F4、F11、F5刷新、退格键来达到效果
<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)||(window.event.keyCode==39))){
//屏蔽Alt+方向键←
//屏蔽Alt+方向键→
event.returnValue=false
}
if((event.keyCode==8)||(event.keyCode==116)||(event.ctrlKey &&event.keyCode==82)){
//屏蔽退格删除键
//屏蔽F5刷新键
//Ctrl+R
event.keyCode=0
event.returnValue=false
}
if(event.keyCode==122){event.keyCode=0event.returnValue=false}//屏蔽F11
if(event.ctrlKey &&event.keyCode==78)event.returnValue=false //屏蔽Ctrl+n
if(event.shiftKey &&event.keyCode==121)event.returnValue=false //屏蔽shift+F10
if(window.event.srcElement.tagName=="A" &&window.event.shiftKey)
window.event.returnValue=false //屏蔽shift加鼠标左键新开一网页
if((window.event.altKey)&&(window.event.keyCode==115)){ //屏蔽Alt+F4
window.showModelessDialog("about:blank","","dialogWidth:1pxdialogheight:1px")
return false
}
}
</script>
