我正在上传多个图像，并将它们放置在ondiv必须切换某些类的某些div中。我是否必须将添加onclick事件的部分放在ajax成功函数中？非常感谢！

我正在使用“ on”上的jquery，但似乎不起作用。可能我缺少了一些东西

这是我的代码：

Javascript：

$(".box-picture-selected > div > div").on( 'click' , function () {
    $(this).toggleClass('image-selected');
});

$('#uploadForm').submit(function (e) {
    e.preventDefault();

    var form = new FormData($('form')[0]);
    var files = document.getElementsByClassName('pics');
    for (var i=0; i<files.length; i++) {
        form.append("files[" + i + "]", files[i][0]); // add receipt to form
    }
    form.append('action', 'upload-photos'); // specify action
    form.append('csrfmiddlewaretoken', '{{ csrf_token() }}');
    $.ajax({
        url: '{{url("/photos/device")}}',
        type: 'POST',
        data: form,
        cache: false,
        processData: false,
        contentType: false,
        success:function(data) {
            $.each($(data), function(key, value) {
                var displayDiv = document.getElementById("displayPics");
                var grid = document.createElement("div");
                grid.setAttribute("class", 'col-md-3 col-sm-4 col-xs-6 grid-changes image-selected');
                var picDiv = document.createElement("div");
                picDiv.setAttribute("class" , 'col-xs-12 images-box');
                picDiv.setAttribute("style", 'background-image: url({{ url('fit/?image='.urlencode(asset('filestorage/temp'))) }}' + '%2F' + value + ');'  );
                displayDiv.appendChild(grid);
                grid.appendChild(picDiv);
            });
        },
        error: function(xhr, desc, err) {
            // I have some error handling logic here
        }
    });
});

HTML：

<div id="displayPics" class="col-xs-12 grid-4-picture">
      @if (isset($files) && !empty($files))
          @foreach ($files as $photo)
              <div class="col-md-3 col-sm-4 col-xs-6 grid-changes">
                  <div class="col-xs-12 images-box" style="background-image: url({{ url('fit/?image='.urlencode(asset('filestorage/temp/'.$photo))) }});"></div>
                  <input type="hidden" value="{{ url('fit/?image='.urlencode(asset('filestorage/temp/'.$photo))) }}">
             </div>
          @endforeach
       @endif
    </div>
