javascript - 等待新打开的窗口关闭后再继续

Question

我正在使用一个包含 window.open 的循环，我正在寻找一种方法来等待上一个窗口关闭后再启动下一个窗口。

for(...){
          window.open('index.html', '_blank', 'nodeIntegration=yes');

Answer 1

Simple for loop will not work. This can be achieved by setInterval. Please refer the code below.

var MyWin = null;//window obejct will assign in future
var i = 0;//Strating index of loop
var len = 5;//length of loop
var myInterval = setInterval(function () {
    if ((!MyWin || MyWin.closed) && i < len) {
        MyWin = window.open("http://www.google.com/");
        i++;
    }
    else if (i >= len) {
        clearInterval(myInterval);//dont forget to clear interval
    }
}, 100);
