如何在ul中获取lis的元素

Question

Hi guys I'm trying to get the ids of the <li> but im getting undefined, I'm using laravel.

This is in my view

<ul class="nav nav-pills nav-stacked" id="listas">
                        @foreach(Auth::user()->empresas as $empresa)
                            <li>
                                <a href="#" class="seleccion" id="{{$empresa->id}}" data-id="{{$empresa->id}}"
                                   data-nombre="{{$empresa->nombre}}">{{$empresa->nombre}}
                                    <span class="pull-right text-red item{{$empresa->id}}"></span></a>
                            </li>
                        @endforeach

 </ul>

My js

   $(document).on('click', '.seleccion', function () {
    $('#listas').find('li').each(function () {
      console.log($(this).attr('id'))
    })
  })

Answer 1

Since your li s don't actually have an id attribute, you should look for it in the a child of your li s, like this.

$(document).on('click', '.seleccion', function () {
    $('#listas').find('li > a').each(function () {
        console.log($(this).attr('id'));
    });
});

Answer 2

You try to read a not existing attribute from your <li> elements.

@foreach(Auth::user()->empresas as $empresa)
  <li id="myId">  <--- HERE
    <a href="#" class="seleccion" id="{{$empresa->id}}" data-id="{{$empresa->id}}"
     data-nombre="{{$empresa->nombre}}">{{$empresa->nombre}}
       <span class="pull-right text-red item{{$empresa->id}}"></span>
    </a>            
  </li>
@endforeach

Answer 3

Like the li don't has id you must change your markup or change the js

  $(document).on('click', 'a.seleccion', function () {
      console.log($(this).attr('id'));
  });

Answer 4

You can use $(this)

 $( ".seleccion" ).click(function() {
        var id = $(this).attr('data-id'));
        console.log(id);
 });
