当div已经打开时如何隐藏div？

Question

I couldn't think of any better title, so I will try to explain my question here as clear as possible. I'm quite a newbie in JQuery so this is probably a very easy question.

I have some divs with a button on it. When you click the button, another div should pop-up. My question is: How can I make the div, which is already open, close when clicking on another button?

I made a fiddle with some example code: http://jsfiddle.net/zuvjx775/1/

And the example code here:

HTML:

<div class="wrapper">
    <div class="test">
        <input type='button' class='showDiv' id="1" value='click!' />    
    </div>
    <div class="show_1">

    </div>
</div>
<br>
<div class="wrapper">
    <div class="test">
        <input type='button' class='showDiv' id="2"value='click!' /> 
    </div>
    <div class="show_2">

    </div>
</div>

JQuery:

$('.showDiv').on('click', function(){
    var id = $(this).attr('id');
    $('.show_'+id).show();
});

When show_1 for example is visible, and I click on the button in div2, I want show_2 to come up, which it does, but show_1 to dissapear.

Can someone point me in the right direction?

You can hide all divs that their class starts with 'show' before show the one you want. For example:

 $('.showDiv').on('click', function() { var id = $(this).attr('id'); $("div[class^='show']").hide();//find div class starts with 'show' and hide them $('.show_' + id).show(); }); 

 .test { border: 1px solid black; height: 100px; width: 450px; float: left; } .show_1 { width: 50px; height: 50px; background-color: yellow; float: left; display: none; } .show_2 { width: 50px; height: 50px; background-color: green; float: left; display: none; } .wrapper { clear: both; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="wrapper"> <div class="test"> <input type='button' class='showDiv' id="1" value='click!' /> </div> <div class="show_1"> </div> </div> <br> <div class="wrapper"> <div class="test"> <input type='button' class='showDiv' id="2" value='click!' /> </div> <div class="show_2"> </div> </div>

Is the structure of the document fixed? is so... I guess the easiest way of doing this is to just do the following:

 $('.showDiv').on('click', function(){ var id = $(this).attr('id'); if(id == 1){ $('.show_1').show(); $('.show_2').hide(); }else{ $('.show_2').show(); $('.show_1').hide(); } })
