是否可以显示一个div并在切换时隐藏所有其他div?

问题描述：

我有三个标题，所有三个都有一些说明.
当我单击第一个标题时，可以看到其说明.
当我单击第二个标题时，我可以看到其描述.
我的代码在这里:
js:

I have three headings and all three have some description.
when i click on first heading, i can see its description.
when i click on 2nd heading, i can see its description.
my code is here:
js:

<script type="text/javascript">
jQuery(document).ready(function() {
jQuery(".content").hide();
//toggle the componenet with class msg_body
jQuery(".heading").click(function()
{
jQuery(this).next(".content").slideToggle(500);
});
});
</script>

css:

.layer1 {
margin: 0;
padding: 0;
width: 500px;
}

.heading {
margin: 1px;
color: #fff;
padding: 3px 10px;
cursor: pointer;
position: relative;
background-color:#c30;
}
.content {
padding: 5px 10px;
background-color:#fafafa;
}
p { padding: 5px 0; }

html代码:

<div class="layer1">
    <p class="heading">Header-1 </p>
    <div class="content">Lorem ipsum dolor sit amet, consectetuer adipiscing elit orem ipsum dolor sit amet, consectetuer adipiscing elit</div>
    <p class="heading">Header-2</p>
    <div class="content">Lorem ipsum dolor sit amet, consectetuer adipiscing elit orem ipsum dolor sit amet, consectetuer adipiscing elit</div>
    <p class="heading">Header-3</p>
    <div class="content">Lorem ipsum dolor sit amet, consectetuer adipiscing elit orem ipsum dolor sit amet, consectetuer adipiscing elit</div>
</div>

现在，我希望当我单击一个1标题时，其他说明必须隐藏，而第一个标题的说明才可见.
该怎么做..?

Now i want that when i click one 1 heading, other description have to hide and just description of 1st heading is visible.
how to do this..?

答

隐藏所选.content的所有.content兄弟姐妹:

Hide all .content siblings of the chosen .content:

jQuery(".heading").click(function() {
    jQuery(this)
          .next(".content").slideToggle(500)
          .siblings(".content").slideUp(500);
});
