JS倒計時結束關閉頁面:Scripts may close only the windows that were opened by it.

在應用中,經常看見支付成功之後,會有倒計時關閉網頁。去年我寫過一個關閉網頁的小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{//否則
             window.close();
        }
    }
}
 //将task放入周期性定時器,時間間隔為1000
 var timer=setInterval(task,);
           

當時寫的時候是好使的,現在在本地也是好使的。。。可是一到伺服器就不行了,出現下圖的問題

查了下資料,說是在新版的浏覽器中不支援此方法了。詳細解釋看本篇文章,我寫下我的解決辦法,在不支援

window.close()

的頁面,将他變為空白頁。改過之後是這樣的:

function task(){
    var n=$('.autoClose').html()[];
    if(n>){//如果n>1
        n--;//n-1
        $('.autoClose').html($('.autoClose').html().replace(/^\d/,n));
    }else{//否則
        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放入周期性定時器,時間間隔為1000
 var timer=setInterval(task,);
