我的情况类似，但这是当你有几个foobar-s，你想关闭只有一个-每次点击:

查找父case

$(".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'
});

查找子案例

$(".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'
});

你可以使用event. currentarget。它只会点击得到事件的元素。

目标= e => 控制台日志(e . currentTarget); 的; <ul onClick={target}类 < li > < p > <i类 < / p > < / li > < /德>

如果e.target与这个元素相同，则没有单击后代。

$ (' .foobar ')。On ('click'，函数(e) { If (e.target !== this) 返回; Alert('点击foobar'); })； .foobar { 填充:20 px;背景:黄色; ｝ 跨度{ 背景:蓝色;颜色:白色;填充:8 px; ｝ < script src = " https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js " > < /脚本> <div class='foobar'> .foobar (alert) <span>child (no alert)</span> < / div >

如果你不能使用指针事件:none;并且针对现代浏览器，你可以使用composedPath来检测对对象的直接点击，如下所示:

element.addEventListener("click", function (ev) {
    if (ev.composedPath()[0] === this) {
        // your code here ...
    }
})

你可以在这里阅读关于composedPath的更多信息: https://developer.mozilla.org/en-US/docs/Web/API/Event/composedPath

你可以用冒泡来帮助自己:

$('.foobar').on('click', function(e) {
    // do your thing.
}).on('click', 'div', function(e) {
    // clicked on descendant div
    e.stopPropagation();
});
