问题描述

我有这个下拉菜单,只要用户点击一个链接就会滑下来。但是,我不知道如何使它滑动,每当用户点击页面上的某个地方(当然不在菜单上)。



我的CSS看起来像这样:

 < li class =da-header-button message> 
< span class =da-button-count> 32< / span>
< a href =#>通知< / a>
< ul class =subnav>
< li class =head>< span class =bold> Notificatons< / span>< / li>
< li class =item>< a href =#>在菜单< / a>< / li>
< li class =item>< a href =#>在菜单< / a>< / li>
< / ul>
< / li>

我目前的jQuery代码如下所示:

  jQuery(ul.topnav li)。click(function(){//当触发器被点击... 
//以下事件应用于子进程本身(move subnav up and down)
jQuery(this).find(ul.subnav)。slideDown('fast')。show(); //下拉subnav点击
jQuery(这个).hover(function(){
},function(){
jQuery(this).find(ul.subnav)。slideUp('slow'); //当鼠标悬停退出subnav,将其移回
});
});

如果我从这里编辑最后一个jQuery函数: jQuery(this)。 hover(function() to this: jQuery(this).click(function()它不工作,因为它只会slideDown然后



感谢您的帮助。



编辑:



谢谢你们,但是如果我同时打开这两个子菜单怎么办?我如何防止这个?



我只想允许1打开。

解决方案

当点击传播到文档时,向上滑动所有可见的菜单:

  $(document).on(click,function(){
$(。subnav:visible)。slideUp() ;
});

然后通过停止在菜单中防止这种情况发生事件传播。

  $(ul.topnav)。on(click,li,function ){
e.stopPropagation();
$(。subnav:visible,$(this).siblings ())效果基本show( 快)。
$(。subnav,this).slideDown();
});

小提琴:


I have this dropdown menu, that will slideDown whenever my users click on a link. However, I don't know how to make it slideUp, whenever the user click somewhere on the page (Not on the menu of course).

My CSS looks like this:

<li class="da-header-button message">
    <span class="da-button-count">32</span>
    <a href="#">Notifications</a>
    <ul class="subnav">
        <li class="head"><span class="bold">Notificatons</span></li>
        <li class="item"><a href="#">Under menu</a></li>
        <li class="item"><a href="#">Under menu</a></li>
    </ul>
</li>

My current jQuery code looks like this:

jQuery("ul.topnav li").click(function() { //When trigger is clicked...
    //Following events are applied to the subnav itself (moving subnav up and down)
    jQuery(this).find("ul.subnav").slideDown('fast').show(); //Drop down the subnav on click
    jQuery(this).hover(function() {
    }, function(){
        jQuery(this).find("ul.subnav").slideUp('slow'); //When the mouse hovers out of the subnav, move it back up
    });
});

If I edit the last jQuery function from this: jQuery(this).hover(function() to this: jQuery(this).click(function() it does not work, since it will just slideDown and then up right after.

Thank you for your help.

EDIT:

Thanks guys! But what if I have two of these submenus open at the same time? How can I prevent this?

I only want to allow to have 1 open.

解决方案

Slide up all visible menus when a click propagates to the document:

$(document).on("click", function(){
    $(".subnav:visible").slideUp();
});

Then prevent this from happening when you're within menus by stopping the event propagation.

$("ul.topnav").on("click", "li", function(e){
    e.stopPropagation();
    $(".subnav:visible", $(this).siblings()).slideUp("fast");
    $(".subnav", this).slideDown();
});
