展开和折叠div

Question

The expand and collapse functionality is currently working fine but I'd like to modify the functionality so when I click on Expand 1 , and then click on Expand 2 , that Expand 1 should collapse automatically. This means that only one div is allowed to be expanded at once while all the others should remain collapsed.

HTML:

<div class="container">
<div class="header"><span>Expand 1</span>

</div>
<div class="content">
    <ul>
        <li>This is just some random content.</li>
        <li>This is just some random content.</li>
        <li>This is just some random content.</li>
        <li>This is just some random content.</li>
    </ul>
</div>

 <div class="header"><span>Expand 2</span>

</div>
<div class="content">
    <ul>
        <li>This is just some random content.</li>
        <li>This is just some random content.</li>
        <li>This is just some random content.</li>
        <li>This is just some random content.</li>
    </ul>
</div>

CSS

.container {
width:100%;
border:1px solid #d3d3d3;
 }
.container div {
 width:100%;
 }
.container .header {
 background-color:#d3d3d3;
 padding: 2px;
 cursor: pointer;
 font-weight: bold;
 }
 .container .content {
 display: none;
 padding : 5px;
  }

Jquery

$(".header").click(function () {

$header = $(this);
//getting the next element
$content = $header.next();
//open up the content needed - toggle the slide- if visible, slide up, if not slidedown.
$content.slideToggle(500, function () {
    //execute this after slideToggle is done
    //change text of header based on visibility of content div
    $header.text(function () {
        //change text based on condition
        return $content.is(":visible") ? "Collapse" : "Expand";
    });
});

});

Answer 1

You can do,

$(".header").click(function () {
    $header = $(this);
    $content = $header.next();
    $(".content").not($content).slideUp().prev().text("Expand");
    $content.slideToggle(500, function () {
        $header.text(function () {
            return $content.is(":visible") ? "Collapse" : "Expand";
        });
    });

});

Fiddle

• Collapse all, except the current one using the code $(".content").not($content).slideUp().prev().text("Expand");

Answer 2

First you need to collapse other if any already expanded. I updated jsfiddle and it is working now. jsfiddle Try this:

$(".header").click(function () {

CollapseAll(this);    

$header = $(this);
//getting the next element
$content = $header.next();
//open up the content needed - toggle the slide- if visible, slide up, if not slidedown.
$content.slideToggle(500, function () {
    //execute this after slideToggle is done
    //change text of header based on visibility of content div
    $header.text(function () {
        //change text based on condition
        return $content.is(":visible") ? "Collapse" : "Expand";
    });
});

});

function CollapseAll(obj){
$(".header").each(function(i, item){
    var that = $(this);
    if($(this).next().is(":visible") && this != obj){
        $(this).next().slideToggle(500, function () {
            //execute this after slideToggle is done
            //change text of header based on visibility of content div
            that.text(function () {
            //change text based on condition
            return that.next().is(":visible") ? "Collapse" : "Expand";
            });
        });
    }
});
}

You can add these two lines in your JS code to achieve desired result.

$contents = $(".header").not(this).next();
$contents.filter(":visible").slideUp(500).prev().text("Expand");

So complete JS code

$(".header").click(function () {

    $header = $(this);
    //getting the next element
    $content = $header.next();
    //open up the content needed - toggle the slide- if visible, slide up, if not slidedown.
    $content.slideToggle(500, function () {
        //execute this after slideToggle is done
        //change text of header based on visibility of content div
        $header.text(function () {
            //change text based on condition
            return $content.is(":visible") ? "Collapse" : "Expand";
        });
    });

    // Get all content panels and Hide them
    $contents = $(".header").not(this).next();
    $contents.filter(":visible").slideUp(500).prev().text("Expand");

});

The idea is to select all header elements excluding this clicked header and if they are visible hide them.

Hope this helps.

You have to select the content sections of headers that were not clicked and slide them up. Something like:

$(".header").click(function () {
    $header = $(this);
     //getting the next element
     $content = $header.next();
     //toggle other content area slides
    var notClicked =  $('.header').not(this).next().slideUp(500);
    $content.slideToggle(500, function () {
        //execute this after slideToggle is done
         //change text of header based on visibility of content div
        $header.text(function () {
            //change text based on condition
             return $content.is(":visible") ? "Collapse" : "Expand";
        });
    });
});

You can add this to the end of your click code. It collapses all of the siblings then performs your text check after the collapse.

Fiddle

$header.siblings(".header").each(function(index,obj){
    header = $(obj);
    content = header.next();
    content.slideUp(500, function(){
        header.text(function () {
            return content.is(":visible") ? "Collapse" : "Expand";
        });             
    });

});
