            <!-- AddThis Button END -->

我希望当我点击Refer your friends 时它会触发addthis_button_email addthis_button_preferred_3 at300b 并且它会显示一个弹出窗口。

我试过下面的代码

jQuery("div#starpline_timestamp_refer").click(function(){
       // trigger second button 
       jQuery(".addthis_button_email addthis_button_preferred_3 at300b").click()
       return false;
    });

好吧，现在看看它是如何触发的。

实际上它是一个元素列表。我只展示了一件商品。所以每次我点击它都会获取最后一项属性。我们可以从列表中正确选择一项吗？我们怎样才能做到这一点？

您缺少类选择器 [dot] 并删除选择器之间的空格:

jQuery(".addthis_button_email.addthis_button_preferred_3.at300b").click()
//                 here       ^^            and here      ^^
