js monitors mouse click (onmousedown) and keyboard click (onkeydown) events and automatically jumps to the page. Friends who are learning can refer to it

$(function(){
var i = 0;
document.onmousedown=function(event){ 
 if(i==1){
window.open('http://www.njxblog.com');
}
//setTimeout(function (){window.open('http://www.jb51.net')},2000); //定时不太好使，会被浏览器当成广告的
i++;
 };
var j = 0;
document.onkeydown=function(event){ 
 if(j==1){
window.open('http://www.njxblog.com');
}
//setTimeout(function (){window.open('http://www.jb51.net')},2000);  //定时不太好使，会被浏览器当成广告的
j++;
 };
});
