jQuery滑动面板-打开另一个面板时关闭一个面板/如何仅打开一个面板？

Question

I have three sliding panels in my html. The thing is that panels overlay each other when open. I would like to get a function that create an event when one panel (eg. #panel1) is open already and the user will click on the other one (#panel2) then the first one (#panel1) will slide out so there can be only one panel open at a time.

Anyone can help me with that??

Thanks in advance.

HTML:

    <ul id="menu">
        <li><img id="icon_1" src="images/image1.png"></li>
        <li><img id="icon_2" src="images/image2.png"></li>
        <li><img id="icon_3" src="images/image3.png" ></li>
    </ul>

    <div id="panel1"></div>
    <div id="panel2"></div>
    <div id="top_panel"></div>

jQuery (#panel1 and #panel2 function taken from http://web.archive.org/web/20150227082803/http://www.jqeasy.com/jquery-slide-panel-plugin ):

    $(document).ready(function(){
        $('#panel1').slidePanel({
            triggerName: '#icon_1',
            speed: 'slow'
    });
        $('#panel2').slidePanel({
            triggerName: '#icon_2',
            speed: 'slow'
        });   
    });

    $(document).ready(function(){
        $("#icon_3").click(function(){
            $("#top_panel").slideToggle("slow");
        });
    });

Something in these lines. I would you data-* attributes to provide a relation between the panels and the images. The follow up the logic based on the conditions.

Javascript

$('#panel1').slidePanel({
    speed: 'slow',
    position: 'static'
});
$('#panel2').slidePanel({
    speed: 'slow',
    position: 'static'
});

$("[id^=icon]").click(function () {
    // Current active panel
    var $currPanel = $('#' + $(this).data('panel'));

    // Slideup all the other panels other than $currPanel
    $('.panel').not($currPanel).slideUp();
    // If $currPanel has no active class only then slide down
    if (!$currPanel.hasClass('current')) {
        $currPanel.slideDown("slow");
    }
    // Add class active to current panel
    $currPanel.addClass('current');
    // Remove class for other panels
    $('.panel').not($currPanel).removeClass('current');
});

HTML

<ul id="menu">
    <li>
        <img id="icon_1" src="images/image1.png" data-panel="panel1">
    </li>
    <li>
        <img id="icon_2" src="images/image2.png" data-panel="panel2">
    </li>
    <li>
        <img id="icon_3" src="images/image3.png" data-panel="top_panel">
    </li>
</ul>
<div id="panel1" class="panel"></div>
<div id="panel2" class="panel"></div>
<div id="top_panel" class="panel"></div>
