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 ...
    }
})

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 >

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'
});

//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)
});

这将停止点击事件在.foobar元素的任何子元素上的传播(冒泡)，因此事件不会到达.foobar元素以触发它们的事件处理程序。

这里是一个演示:http://jsfiddle.net/bQQJP/

$(".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
})
