具有动态 ajax 内容的 Bootstrap Accordion [英] Bootstrap Accordion with dynamic ajax content

问题描述

我想用来自 ajax 的内容创建一个手风琴.

所以，我的 HTML 是:

//动态内容在这里

我的成功 ajax 是:

成功:函数(数据){data.items.forEach(function(e) {$('.latestinfo').append('<div class="panel panel-default"><div class="panel-heading" role="tab" id="headingOne"><h4 class="panel-title"><a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">' + e.title + '</a></h4></div><div id="collapseOne" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingOne"><div class="panel-body">' + e.content + '</div></div></div>');});}

目前，

• 显示内容
• 当我点击第一个时它会打开
• 当我点击其他时，第一个切换(打开/关闭)

问题是手风琴没有像我上面描述的那样正常工作.

解决方案

An id MUST BE UNIQUE(大声说出来并想象回声)...

您可以使用 .forEach() 提供的 index 来创建唯一的 id.
;)

并且您可以使用 + 将字符串连接到多行...
提高可读性.

//假设这个 JSON.var data = {items:[{title:"ONE",content:"Something-1"},{title:"TWO",content:"Something-2"},{title:"THREE",content:"Something-3"}]};var 成功 = 函数(数据){data.items.forEach(function(item,index){$('.latestinfo').append('<div class="panel panel-default">'+'<div class="panel-heading" role="tab" id="heading_'+index+'">'+'<h4 class="panel-title">'+'<a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapse_'+index+'" aria-expanded="true" aria-controls="collapse_'+index+'">'+item.title+'</a>'+'</h4>'+'</div>'+'<div id="collapse_'+index+'" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="heading_'+index+'">'+'<div class="panel-body">'+item.content+'</div>'+'</div>'+'</div>');});}//伪装一个 ajax 响应...成功(数据);

I want to create an accordion with a content from ajax.

So, my HTML is :

<div class="latestinfo panel-group" id="accordion" role="tablist" aria-multiselectable="true">
// DYNAMIC CONTENT HERE
</div>

and my success ajax is :

success: function(data) {
            data.items.forEach(function(e) {
                $('.latestinfo').append('<div class="panel panel-default"><div class="panel-heading" role="tab" id="headingOne"><h4 class="panel-title"><a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">' + e.title + '</a></h4></div><div id="collapseOne" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingOne"><div class="panel-body">' + e.content + '</div></div></div>');
            });
       }

Currently ,

• The content is displayed
• When i click the first one it open
• When i click other, the first toggle ( open / close )

The problem is that the accordion is not working correctly as I described above.

解决方案

An id MUST BE UNIQUE (say it loud and imagine echo)...

You can use the index provided by .forEach() to create unique id.
;)

And you can use + to concatenate a string on multiple lines...
Improves readability.

// Assuming this JSON.
var data = {items:[{title:"ONE",content:"Something-1"},
                   {title:"TWO",content:"Something-2"},
                   {title:"THREE",content:"Something-3"}
                  ]
           };


var success = function(data) {
  data.items.forEach(function(item,index) {
    $('.latestinfo').append(
        '<div class="panel panel-default">'+
          '<div class="panel-heading" role="tab" id="heading_'+index+'">'+
            '<h4 class="panel-title">'+
              '<a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapse_'+index+'" aria-expanded="true" aria-controls="collapse_'+index+'">'+
                  item.title+
              '</a>'+
            '</h4>'+
          '</div>'+
          '<div id="collapse_'+index+'" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="heading_'+index+'">'+
            '<div class="panel-body">'+
              item.content+
            '</div>'+
          '</div>'+
        '</div>'
      );
  });
}

// Feaking an ajax response...
success(data);
