Question

我有一个简单的问题。我正在尝试在用户点击div时显示视频。然后，当用户点击页面上不在视频上的任何位置时，隐藏该视频。完成了数百万次，但我无法找到如何做到这一点，Stackoverflow上的其他部分解决方案失败了。这是完整的代码：

当我点击“.clickForVideo”div时，不会显示任何视频。如果我注释掉标记为“参考1”的行，然后单击“.clickForVideo”，则会出现视频/ div，但是，如果按预期单击文档，则不会消失。如何更改我的代码或为此问题提供不同的解决方案。非常感谢。安德鲁

这种情况正在发生，因为 clickForVideo 也是文档的一部分。当您单击它时，文档（父级）的单击事件也会被调用，并再次隐藏它。

试试这个：

$(function(){
    $(".clickForVideo").click(function(event) {
        event.stopPropagation(); //<-----
        $("#videoDiv").show();
    });
    $(document).click(function(event){
        if ($('#videoDiv').is(':visible')) {
          if(!$(event.target).closest('#videodiv').length) {
            $('#videoDiv').hide();
          }
        }
    });
});

event.stopPropagation()（DOC）应该阻止事件冒泡到父级，即document

jQuery - 在Div2上显示Div1单击，然后在文档单击上隐藏Div1
