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。

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

                <label for=" Oraganization" class="active"> Oraganization</label>

Answer 1

Fiddle Here

这是因为你在装载它时会打开第一个手风琴。要解决此问题，请在加载$($('#accordion .expand-icon')[0]).click();时对其执行单击操作。请查看此处的工作示例http://www.bootply.com/vGoKbvfKtl

Answer 2

您只是在页面加载时显示所有手风琴，因为没有隐藏任何位置。

根据您的代码由于只有第一个Accordion包含数据，否则会显示，否则每个可展开的div都会显示。

对此的解决方案是向类手风琴添加一个隐藏类，以便它不会在开始时显示，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()
    }) 
});
