有的時(shí)候別人可能會(huì)故意刷我們的網(wǎng)站鏈接，在后面加上參數(shù)來訪問網(wǎng)站，例如‘http://www.tjdsmy.cn/?_t=1539913651’我們想實(shí)現(xiàn)的效果是自動(dòng)去掉后綴包含？部分，實(shí)現(xiàn)代碼如下

if(top != self){

top.location=self.location;

}else{

var url = location.search;

if(url){

var old_url = window.location.href;

var new_url = old_url.substring(0, old_url.indexOf('?'));

self.location = new_url;

}

}
