Jquery 手风琴在页面加载时折叠

Question

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

            <li class="expandable root">

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

Answer 1

在这里小提琴

这是因为您在加载时打开了第一个手风琴。 要修复它，请在加载时使用$($('#accordion .expand-icon')[0]).click(); . 检查这里的工作示例http://www.bootply.com/vGoKbvfKtl

Answer 2

您只是在页面加载时显示所有手风琴，因为没有隐藏任何地方。

根据您的代码，由于只有第一个 Accordion 包含数据，所以它会被显示，否则每个可扩展的 div 都会被显示。

对此的解决方案是在类手风琴中添加一个隐藏类，使其在开始时不显示，在单击功能时，您可以删除该类并显示它。

 $(document).ready(function(){ $('.expand-icon').click(function(){ $('ul').removeClass('hide') var elem = $(this); if(elem.hasClass('active')) { elem.removeClass('active'); var subElem = elem.siblings('ul'); var nestedElem =elem.siblings('ul').find('ul'); if(nestedElem.length == 0) { subElem.slideUp('fast'); } else { nestedElem.slideUp('fast',function(){ 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); }); $('.organization').click(function(){ $('.accordion')[0].click() }) });

 <ul> <li class="expandable "> <label for=" Oraganization" class="active"> Oraganization</label> <span class=" organization active expand-icon glyphicon glyphicon-minus"></span> <ul id=""> <li class="expandable"> <span class="expand-icon glyphicon glyphicon-plus"></span> <input type="checkbox" id="Manager-1"> <label for="Manager-1"> Manager-1</label> <ul class="accordion hide"> <li> <input type="checkbox" id="Sub-Manager-1"> <label for="Sub-Manager-1"> Sub-Manager-1</label> </li> <li class="expandable"> <span class="expand-icon active glyphicon glyphicon-minus"></span> <input type="checkbox" id="Sub-Manager-2"> <label for="Sub-Manager-2"> Sub-Manager-2</label> <ul class="accordion"> <li> <input type="checkbox" id="Associate-1"> <label for="Associate-1"> Associate-1</label> </li> <li> <input type="checkbox" id="Associate-2"> <label for="Associate-2"> Associate-2</label> </li> <li class="expandable"> <span class="expand-icon active glyphicon glyphicon-minus"></span> <input type="checkbox" id="Associate-5"> <label for="Associate-5"> Associate-5</label> <ul class="accordion"> <li> <input type="checkbox" id="Sub-associate-1"> <label for="Sub-associate-1"> Sub-associate-1</label> </li> <li> <input type="checkbox" id="Sub-associate-2"> <label for="Sub-associate-2"> Sub-associate-2</label> </li> <li> <input type="checkbox" id="Sub-associate-3"> <label for="Sub-associate-3"> Sub-associate-3</label> </li> <li> <input type="checkbox" id="Sub-associate-4"> <label for="Sub-associate-4"> Sub-associate-4</label> </li> </ul> </li> </ul> </li> </ul> </li> <li class="expandable"> <span class="expand-icon active glyphicon glyphicon-plus"></span> <input type="checkbox" id="Manager-2"> <label for="Manager-2"> Manager-2</label> </li> <li class="expandable"> <span class="expand-icon active glyphicon glyphicon-plus"></span> <input type="checkbox" id="Manager-3"> <label for="Manager-3"> Manager-3</label> </li> </ul> </li> </ul>
