Jquery 创建手风琴类型的内容

我试图创建一些接近jquery手风琴的东西。我不确定我错在哪里

在第一个框打开的位置，单击第二个框时，第一个框关闭，第二个框打开

到目前为止，我只做到了这一点

我的html

<div class="description">

唉。我不知道你为什么要重新发明轮子或尝试重新使用“点击”切换方法，但你想得太多了。这很简单：

你为什么要重新发明轮子？你知道如果你不想要整个库，你可以下载jQueryUI的特定“部分”，对吧？比如：？

$.fn.toggleClick=function(){
    var functions=arguments;
    return this.click(function(){
        var iteration=$(this).data('iteration')||0;
        functions[iteration].apply(this,arguments);
        iteration= (iteration+1) %functions.length;
        $(this).data('iteration',iteration);
    });
};


var $dscr = $('.description'),
    $switch = $('.toggle-link'),
    initHeight = 40; // Initial height

$dscr.each(function () {
    $(this).data("realHeight", $(this).height()); // Create new property realHeight
}).css({
    overflow: "hidden",
    height: initHeight  
});

$switch.toggleClick(function () {
    $(this).prevAll('.description:first').animate({
        height: $dscr.data("realHeight")
    }, 600);
    $(this).html("-");

}, function () {
    $dscr.animate({
        height: initHeight
    }, 600);
    $switch.html("+");
});

var initHeight = 40; // Initial height

$('.description')
.each(function(e) { $(this).data("realHeight", $(this).height()); })
.css({ height: initHeight, overflow: 'hidden' });

$('.toggle-link').on('click', function(e) {
    var $desc = $(this).prev();
    if ($desc.hasClass('open')) {
        $(this).text('+');
        $desc.removeClass('open').animate({ height: initHeight }, 600)
    }
    else {
        $(this).text('-');
        $desc.addClass('open').animate({ height: $desc.data('realHeight') }, 600)
        .siblings('.open').removeClass('open')
        .animate({ height: initHeight }, 600, function(e) { $(this).next().text('+'); });
    }
});
