jquery - 如果其他 Accordion 在 jQuery 中打开，则关闭 Accordion

Question

我在一个页面上有多个 jQuery Accordion ，它们都具有不同的 id 等。我试图一次只允许打开一个 Accordion 。例如，用户打开一个 Accordion ，然后转到另一个 Accordion ，新的 Accordion 打开，而用户刚刚使用的 Accordion 关闭。

有办法这样做吗？

下面是一个 Accordion 的示例......它们目前看起来都一样。

<div id="accordion">


<h3 class="one" href="#section1">Location</a></h3>
<div class="tab1">
 
    <form class="myform">
    <label><b>Weeks</b></label><br>
        <input type = "checkbox" id = "allweeks" /> <label for = "allweeks">All Weeks</label><br>
        <input type = "checkbox" id = "w1" /> <label for = "w1">Week 1</label><br>
        <input type = "checkbox" id = "w2" /> <label for = "w2">Week 2</label><br>
        <input type = "checkbox" id = "w3"  /> <label for = "w3">Week 3</label><br>
        <input type = "checkbox" id = "w4" /> <label for = "w4">Week 4</label><br>
        <input type = "checkbox" id = "w5" /> <label for = "w5">Week 5</label></br>
        <input type = "checkbox" id = "w6"  /> <label for = "w6">Week 6</label><br>
        <input type = "checkbox" id = "w7" /> <label for = "w7">Week 7</label><br>
        <input type = "checkbox" id = "w8" /> <label for = "w8">Week 8</label><br>
        <input type = "checkbox" id = "w9" /> <label for = "w9">Week 9</label><br>
        <input type = "checkbox" id = "w10"  /> <label for = "w10">Week 10</label><br>
        <input type = "checkbox" id = "w11"  /> <label for = "w11">Week 11</label><br>
        <input type = "checkbox" id = "w12"  /> <label for = "w12">Week 12</label><br>
    
            
     </form>

</div>

这些是我目前正在使用的脚本

    <script>


$(function() {
    $( "#accordion,#accordion1,#accordion2,#accordion3,#accordion4,#accordion5" ).accordion();
    

});


$(function() {
    var icons = {
        header: "ui-icon-circle-arrow-e",
        headerSelected: "ui-icon-circle-arrow-s"
    };
    $( "#accordion,#accordion1,#accordion2,#accordion3,#accordion4,#accordion5" ).accordion({
        icons: icons,
        collapsible: true
    });
    $( "#toggle" ).button().toggle(function () {
        $( "#accordion,#accordion1,#accordion2,#accordion3,#accordion4,#accordion5" ).accordion( "option", "icons", false );
    }, function () {
        $( "#accordion,#accordion1,#accordion2,#accordion3,#accordion4,#accordion5" ).accordion( "option", "icons", icons );
    });
});


$(function() {
$("#accordion,#accordion1,#accordion2,#accordion3,#accordion4,#accordion5").accordion({ header: "h3", collapsible: true, active: false }); });

</script>

假设您使用的是 jQuery UI Accordion ，您可以使用 .accordion('activate', false) 折叠所有部分。

首先，在 HTML 中，为所有折叠容器指定 class="accordion" ，使它们作为一个组更容易寻址。如果您需要单独处理 Accordion ，您可以保留 id="accordion1" 等属性。

然后，在单个 $(function(){...}) 结构中初始化 Accordion (仅一次，而不是 3 次)，如下所示:

$(function() {
    var activeAccordian = null;
    var $accordions = $(".accordion").on('click', function() {
        activeAccordian = this;
    }).accordion({
        collapsible: true,
        active: false,
        icons: false
    }).on('accordionchange', function(event, ui) {
        $accordions.not(activeAccordian).accordion('activate', false);
    });
});

使用 activeAccordian 跟踪事件的折叠面板非常重要，因为它可以抑制新打开的折叠面板的相互重新关闭。

编辑:

下面的“aussi la 解决方案”，其中 .on('accordionchange' ...) 替换为 .on('click' ...)让我意识到整个事情将简化为:

$(function() {
    var $accordions = $(".accordion").accordion({
        collapsible: true,
        active: false,
        icons: false
    }).on('click', function() {
        $accordions.not(this).accordion('activate', false);
    });
});

跟踪事件 Accordion 的需要消失了，因为点击处理程序中的 .not(this) 就足够了。
