jQuery link 上的点击事件不会被 vanilla JS 捕获

Question

我正在使用以下 Vanilla 绑定来模拟 jQuery 委托事件：

document.addEventListener('click', function(e) {
    console.log("some element was clicked");
    console.log(e.target);

    //here's where I would filter by target
});

一切正常，除非我尝试用 jQuery 在 link 元素 <a href="#"> 上触发点击事件。那就根本不行了。香草点击事件处理程序不会被触发。

Reproduction working on <b> element

$('button').click(function() {
    $('ul').append('<li><b>New</b></li>');
});

document.addEventListener('click', function(e) {
    console.log("some element was clicked");
    console.log(e.target);
});

$(document).on('keydown', function(){
    console.warn("-------Trigger--------")
 $('li').find('b').trigger('click');
});

div{
    background: yellow;
    padding:10px 20px;
    border: 1px solid #ccc;
    margin: 10px 0;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button>Add element</button>
<span id="trigger">Trigger</span>
<div>
 Just focus the white panel and press any key. That will trigger the jQuery.click() event as you can see in the code.
</div>
<ul>
    <li>Old element</li>
    <li>Old element</li>
    <li><b>Old element</b></li>
</ul>

相反，如果我将 link 元素替换为粗体元素 <b>，它会按预期工作。这是怎么回事？ Reproduction not working on <a> element

$('button').click(function() {
    $('ul').append('<li><a href="#">New</a></li>');
});

document.addEventListener('click', function(e) {
    console.log("some element was clicked");
    console.log(e.target);
});

$(document).on('keydown', function(){
    console.warn("-------Trigger--------")
 $('li').find('a').trigger('click');
});

div{
    background: yellow;
    padding:10px 20px;
    border: 1px solid #ccc;
    margin: 10px 0;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button>Add element</button>
<span id="trigger">Trigger</span>
<div>
 Just focus the white panel and press any key. That will trigger the jQuery.click() event as you can see in the code.
</div>
<ul>
    <li>Old element</li>
    <li>Old element</li>
    <li><a href="#">Old element</a></li>
</ul>

不，我不想这样使用 [0]：

$('li').find('a')[0].click();

我希望它正常启动：

$('li').find('a').click();

不幸的是，您无法在链接上的 jQuery 中触发本机点击处理程序，它在源代码中被禁用并且评论说 "For cross-browser consistency, don't fire native .click() on links"。

因此，您要么必须使用 jQuery $(document).on("click") 绑定文档点击处理程序，要么直接调用节点 clickHandler $('li').find('a')[0].click();
