Question

这是......顺便说一下，它在jsFiddle中是不对齐的。在我的实际网页中，它是一致的，所以不用担心。

我尝试使用受http://jsbin.com/umubad/2/启发的代码，但我无法弄清楚如何成功实现它。

HTML

  <ul class="navbar cf">
                    <li>
                        <a href="#" class="ActiveListItem">Category</a>
                        <ul>
                            <li><a href="#">1</a></li>
                            <li><a href="#">2</a></li>
                            <li><a href="#">3</a></li>
                            <li><a href="#">4</a></li>
                            <li><a href="#">5</a></li>
                            <li><a href="#">6</a></li>
                            <li><a href="#">7</a></li>
                        </ul>
                    </li>
                </ul>
            </div>

CSS

ul.navbar {

  border-style:solid;
  border-width:1px; 
  border-color:#739FE0;
  width: 100px;                /*Widthchanger1*/

    width:100px;   /*kinda messes with width of text*/
     margin-bottom:1px;

}

ul.navbar li {

    text-decoration:none;
    transition: all .1s ease-in;

}

    ul.navbar li ul {
        margin-top: 0px;               /*Controls space from listdropdown to listchooser*/
        position: absolute;
        background: #222;
        font-size: 14px;

        0 5px 10px rgba(0,0,0,.6);
    }

ol, ul { list-style: outside none none; }

.hidden { display: none; }

JS

$(function() {




  $('.navbar ul li a').click(function(){  
    $('.navbar > li:first-child > a').text($(this).text());
    $('.navbar > li > ul').addClass('hidden');
    $('.navbar li ul').slideToggle(100);
  });
  $('.navbar > li').mouseenter(function(){
    $(this).find('ul').removeClass('hidden');
  });
  $('.ActiveListItem').click(function(){        
    $('.navbar li ul').slideToggle(300);
  });    
});

Answer 1

DEMO：https://jsfiddle.net/j8oawqL4/3/

 $(document).click(function (event) {//if clicked on anywhere

    if (event.target.id != 'category') {//it was not the 'category' dropdown list
        $('.navbar li ul').hide(300);//then hide it
    }
})

Answer 2

$(document).click(function (event) {
alert(event.target.id);
if (event.target.id != 'category') {
    $('.navbar li ul').slideToggle(300);
}

}）

Answer 3

这是我的jsFiddle

修改你的jQuery：

$(function() {

    var container = $('.navbar');


  $('.navbar ul li a').click(function(){  
    $('.navbar > li:first-child > a').text($(this).text());
    $('.navbar > li > ul').addClass('hidden');
    $('.navbar li ul').slideToggle(100);
  });
  $('.navbar > li').mouseenter(function(){
    $(this).find('ul').removeClass('hidden');
  });
  $('.ActiveListItem').click(function(){        
    $('.navbar li ul').slideToggle(300);
  });


 $(document).mouseup(function (e)
    {
    if (!container.is(e.target) 
        && container.has(e.target).length === 0) 
    {
        $('.navbar li ul').slideToggle(300);
    }
     });
});

Answer 4

怎么样？

$("body").on("click", function(e){
    if(!$(e.target).is(".navbar *")){
        $('.navbar li ul').slideUp(100);
    }
});
