jQuery点击<a> not work in safari

Question

Here is my question.
First , I create an anchor tag.
For example , <a id="download_link" href="www.google.com">

Then I use jQuery to trigger "click" event.

$("#download_link").click()

It works well in Chrome but Safari I searched a lot solution like this

但他们也无法解决我的问题。 我该如何解决这个问题？

[更新] 我使用该链接下载内容。完整的代码是：

$('body').append('<a id="download_link" download style="display:none;"></a>')

$("#download_link").attr({
  'href': /* my download url */,
}).get(0).click();
