<ul> <li><a href="#">主菜单1</a></li> <li><a href="#">主菜单2</a></li> <li class="li-other"> <a href="javascript:;">其他<i class="arrow-down"></i></a> <div class="otherbox"> <ul> <li><a href="#">子菜单1</a></li> <li><a href="#">子菜单2</a></li> </ul> </div> </li> </ul>
HTML如上:
JQuery如下:
$('.li-other').on('mousedown',function(event){ event.stopPropagation();//阻止mousedown 事件冒泡(注意只阻止了mousedown事件) event.preventDefault();//阻止当前元素默认事件 $('.li-other').toggleClass("active"); }); $(document).on('mousedown',function(){ $('.li-other').removeClass("active"); });
