我有点击事件发射。它运作良好,做我需要它做的事情。这是问题
我正在构建的小部件的性质通过position: absolute
将元素堆叠在彼此之上当我点击这些堆叠元素中的一个时,只有一个事件被触发,但是id就像每个要触发的元素一样在鼠标光标下点击。有没有办法做到这一点?

请检查演示或在整页中运行代码段,然后单击所有div以查看结果消息。

我在这里做的是:
隐藏顶部元素
和
获取下一个绝对元素与document.elementFromPoint
的坐标,然后重复。
Stack Snippet:
jQuery(document).ready(function(){
$common = $("div.common").on('click.passThrough', function (e, ee) {
var $element = $(this).hide();
try {
if (!ee) $("#output").empty();
$("<div/>").append('You have clicked on: '+$element.text()).appendTo($("#output"));
ee = ee || {
pageX: e.pageX,
pageY: e.pageY
};
var next = document.elementFromPoint(ee.pageX, ee.pageY);
next = (next.nodeType == 3) ? next.parentNode : next //Opera
$(next).trigger('click.passThrough', ee);
} catch (err) {
console.log("click.passThrough failed: " + err.message);
} finally {
$element.show();
}
});
$common.css({'backgroundColor':'rgba(0,0,0,0.2)'});
});

#output {
margin-bottom: 30px;
}
.common {
position: absolute;
height: 300px;
width: 300px;
padding: 3px;
border: 1px #000 solid;
}
.elem5 {
top: 150px;
left: 150px;
}
.elem4 {
top: 180px;
left: 180px;
}
.elem3 {
top: 210px;
left: 210px;
}
.elem2 {
top: 240px;
left: 240px;
}
.elem1 {
top: 270px;
left: 270px;
}

您可以使用customEvent属性
段
//This function changes the color of all child divs
function changeColor(e) {
this.style.background = "red";
}
//this function is attached to the parent div which will send that click event to all divs
function trigger(e) {
//create an event
event = new CustomEvent('click');
//if the event originates from a child div
if (e.target.className == 'box')
//loop through all child div
for (var i = 0; i < all_box.length; ++i) {
//dispatch a click event to each child div
all_box[i].dispatchEvent(event);
}
}
document.getElementById('parent').addEventListener('click', trigger)
var all_box = document.getElementsByClassName('box');
for (var i = 0; i < all_box.length; ++i) {
all_box[i].addEventListener('click', changeColor)
}
.box {
padding: 10px;
display: inline-block;
border: solid black;
}
#parent {
border: solid black;
padding: 10px;
}
;
<div id="parent">
<div class="box" id="primary">box1</div>
<div class="box">box2</div>
<div class="box">box3</div>
<div class="box">box3</div>
</div>
