javascript - Jquery Accordion 在页面加载时崩溃

Question

我正在尝试使用 jquery 创建一个可扩展的 Accordion 。我无法弄清楚我应该如何防止它在页面加载时扩展。我对jquery一无所知，任何帮助将不胜感激。

            <ul>
            <li class="expandable root">

                <label for=" Oraganization" class="active"> Oraganization</label> 
                <span class="pull-right oraganization active expand-icon glyphicon glyphicon-minus"></span> 

                <ul id="accordion">
                    <li class="expandable">
                        <span class="expand-icon active glyphicon glyphicon-minus"></span> 
                        <input type="checkbox" id="Manager-1"> 
                        <label for="Manager-1"> Manager-1</label> 

                        <ul id="accordion">

JS 文件:

$(document).ready(function(){

        var subElem = elem.siblings('ul');
        var nestedElem =elem.siblings('ul').find('ul');

        if(nestedElem.length == 0) {
            subElem.slideUp('fast');
        }
        else {

                subElem.slideUp('fast');
            });
        }
        $.when(elem.removeClass('glyphicon-minus')).then(function(){
            elem.addClass('glyphicon-plus');
        });
    }
    else {
        elem.addClass('active');
        elem.siblings('ul').slideDown('fast',function(){
            elem.siblings('ul').find('ul').slideDown('fast');   
        });
        $.when(elem.removeClass('glyphicon-plus')).then(function(){
            elem.addClass('glyphicon-minus');
        });
    }

});


$('.expandable :checkbox').on('change', function() {

    $(this).parent().find('li input[type=checkbox]').prop('checked', $(this).is(':checked'));
    var sibs = false;
    $(this).closest('ul').children('li').each(function () {
        if($('input[type=checkbox]', this).is(':checked')) sibs=true;
    });
    $(this).parents('ul').siblings(':checkbox').prop('checked', sibs);

});

});

这是因为您在加载时打开了第一个 Accordion 。要修复此问题，请在加载时使用 $($('#accordion .expand-icon')[0]).click(); 对其执行单击操作。在此处查看工作示例 http://www.bootply.com/vGoKbvfKtl
