//下面兩個是用於中止廣告的代碼，一個是鼠標的，一個是鍵盤的
function vis_false(){
if(event.button==1){

}
使用的時候<body onLoad="go()" OnMouseDown="vis_false()">
function vis_false(){
if(event.keyCode==65){//字母a
pic1.display="none";
window.clearInterval(action);
}else if(event.keyCode==66){//字母b
pic1.display="inline";
go();
}
OnKeyDown="vis_false()"//當然這裏也要改！
very good,,非常好用！
