我有一个带有分类的
foobarfoobar$('.foobar').on('click', function() { /*...do stuff...*/ });
我希望仅在单击 DIV 中的某处而不是其子 DIV 时触发。
如果
e.targetthis$('.foobar').on('click', function(e) {
if (e.target !== this)
return;
alert( 'clicked the foobar' );
});.foobar {
padding: 20px; background: yellow;
}
span {
background: blue; color: white; padding: 8px;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class='foobar'> .foobar (alert)
<span>child (no alert)</span>
</div>我没有得到公认的工作答案，但这似乎可以解决问题，至少在普通 JS 中是这样。
if(e.target !== e.currentTarget) return;
如果您不介意只针对较新的浏览器，还有另一种可行的方法。只需添加CSS
pointer-events: none;
您想要捕获点击的 div 的任何子级。这是支持表
您可以使用对您有利的冒泡：
$('.foobar').on('click', function(e) {
// do your thing.
}).on('click', 'div', function(e) {
// clicked on descendant div
e.stopPropagation();
});
//bind `click` event handler to the `.foobar` element(s) to do work,
//then find the children of all the `.foobar` element(s)
//and bind a `click` event handler to them that stops the propagation of the event
$('.foobar').on('click', function () { ... }).children().on('click', function (event) {
event.stopPropagation();
//you can also use `return false;` which is the same as `event.preventDefault()` and `event.stopPropagation()` all in one (in a jQuery event handler)
});
这将停止
click.foobar.foobar这是一个演示：http://jsfiddle.net/bQQJP/
我遇到了同样的问题并提出了这个解决方案（基于其他答案）
$( ".newsletter_background" ).click(function(e) {
if (e.target == this) {
$(".newsletter_background").hide();
}
});
基本上它表示如果目标是 div，则运行代码，否则不执行任何操作（不要隐藏它）
$(".advanced ul li").live('click',function(e){
if(e.target != this) return;
//code
// this code will execute only when you click to li and not to a child
})
您可以使用event.currentTarget。它只会执行点击事件，只有获得事件的元素。
target = e => {
console.log(e.currentTarget);
};<ul onClick={target} className="folder">
<li>
<p>
<i className="fas fa-folder" />
</p>
</li>
</ul>如果您无法使用
pointer-events: none;composedPathelement.addEventListener("click", function (ev) {
if (ev.composedPath()[0] === this) {
// your code here ...
}
})
您可以在此处阅读有关composedPath的更多信息： https://developer.mozilla.org/en-US/docs/Web/API/Event/composedPath
定义事件时，该事件具有属性
thise.target由于事件是在元素的子元素中继承的，因此检查目标是否
function doSomething(event) {
if (this == event.target){
// do something
}
}
我的情况类似，但这是当您有几个
foobar$(".foobar-close-button-class").on("click", function () {
$(this).parents('.foobar').fadeOut( 100 );
// 'this' - means that you finding some parent class from '.foobar-close-button-class'
// '.parents' -means that you finding parent class with name '.foobar'
});
$(".foobar-close-button-class").on("click", function () {
$(this).child('.foobar-close-button-child-class').fadeOut( 100 );
// 'this' - means that you finding some child class from '.foobar-close-button-class'
// '.child' -means that you finding child class with name '.foobar-close-button-child-class'
});
// if its li get value
document.getElementById('li').addEventListener("click", function(e) {
if (e.target == this) {
UodateNote(e.target.id);
}
})
function UodateNote(e) {
let nt_id = document.createElement("div");
// append container to duc.
document.body.appendChild(nt_id);
nt_id.id = "hi";
// get conatiner value .
nt_id.innerHTML = e;
// body...
console.log(e);
