JS倒计时结束关闭页面:Scripts may close only the windows that were opened by it.

在应用中,经常看见支付成功之后,会有倒计时关闭网页。去年我写过一个关闭网页的小demo

HTML
JS
function task(){
    var n=$('.autoClose').html()[];
    if(n>){//如果n>1
        n--;//n-1
        $('.autoClose').html($('.autoClose').html().replace(/^\d/,n));
    }else{//否则
             window.close();
        }
    }
}
 //将task放入周期性定时器,时间间隔为1000
 var timer=setInterval(task,);
           

当时写的时候是好使的,现在在本地也是好使的。。。可是一到服务器就不行了,出现下图的问题

查了下资料,说是在新版的浏览器中不支持此方法了。详细解释看本篇文章,我写下我的解决办法,在不支持

window.close()

的页面,将他变为空白页。改过之后是这样的:

function task(){
    var n=$('.autoClose').html()[];
    if(n>){//如果n>1
        n--;//n-1
        $('.autoClose').html($('.autoClose').html().replace(/^\d/,n));
    }else{//否则
        var userAgent = navigator.userAgent;
        if (userAgent.indexOf("Firefox") != - || userAgent.indexOf("Chrome") !=-) {
            window.location.href="about:blank";
        } else {
            window.opener = null;
            window.open("", "_self");
             window.close();
        }
    }
}
 //将task放入周期性定时器,时间间隔为1000
 var timer=setInterval(task,);
