Bootstrap Accordion with dynamic ajax content

问题

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.

回答1:

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);
