如何使用Javascript打开页面加载上的新选项卡？

Question

我正在使用javascript打开新标签页。我在浏览器中运行时已经完成了一些编码，当我在浏览器窗口中单击它打开一个新选项卡时，它没有打开新选项卡。

附上代码 JS代码

var Light = Light || {};
 Light.Popup = {
    popName:  'Chip-LightPopup',
    alwaysPop: false, // refresh = new pop
    onNewTab: true,
    /**
     * 1: window onclick,
     * 2: window onload -> document onclick
    */

Light.Popup.create('http://google.com', {alwaysPop: true});

你做不到。

如果启动它们的代码不是来自用户触发的事件，则所有现代浏览器中内置的弹出窗口阻止程序将阻止新的窗口/选项卡。

页面加载不是用户触发的事件。
