无法使用jquery触发mousedown事件

I'm trying to simulate a click event in http://translate.google.com with jquery. For that purpose, I loaded jquery file with this code:

我正在尝试使用jquery在http://translate.google.com中模拟点击事件。为此,我用这段代码加载了jquery文件:

var script = document.createElement("script");
script.src = "http://code.jquery.com/jquery-1.10.1.min.js";
document.body.appendChild(script);

Then I'm trying to simulate a click on an element with a selector, like this:

然后我试图用选择器模拟对元素的点击,如下所示:

jQuery(".goog-inline-block.goog-flat-menu-button-caption").trigger("mousedown")

I also tried this click event instead of mousedown:

我也试过这个点击事件而不是mousedown:

jQuery(".goog-inline-block.goog-flat-menu-button-caption").trigger("click")

None of them gives the effect of manually clicking to the div, namely opening a new div. I attached the ss of desired behaviour.

它们都没有给出手动点击div的效果,即打开一个新的div。我附上了所需行为的ss。

What can be the cause for jquery not working? Or how can I simulate the effect in any other ways?

jquery无法工作的原因是什么?或者我如何以其他方式模拟效果?

Edit: Adding jQuery seems to be successful in the sense that I can use jQuery method to select elements and change contents of them etc.

编辑:添加jQuery似乎是成功的,因为我可以使用jQuery方法来选择元素并更改它们的内容等。

The solution was creating a MouseEvent and dispatching it to the element, like this:

解决方案是创建一个MouseEvent并将其分派给元素,如下所示:

var e1 = document.createEvent("MouseEvents");
e1.initMouseEvent("mousedown", true, true, window, 1, 0, 0, 0, 0, false, false, false, false, 0, null);
jQuery('#gt-sl-gms')[0].dispatchEvent(e1)

It seems jQuery's event mechanism uses a different dispatching system, since it can not trigger the listener function, though I didn't confirm this info.

似乎jQuery的事件机制使用不同的调度系统,因为它不能触发监听器功能,尽管我没有确认这个信息。
