解释代码 <div class="loginin" v-if="$store.state.token">

这段代码使用了 Vue.js 的指令 v-if，它的意思是：如果 $store.state.token 存在且为真，则显示一个包含 class 为 "loginin" 的 div 元素。

在 Vue.js 应用程序中，$store 是一个全局状态管理器对象，它可以在任何组件中访问。state 是 $store 对象中的一个属性，它包含了应用程序的状态数据。因此，$store.state.token 可以理解为应用程序中的一个名为 token 的状态数据。

总之，这段代码的作用是：如果用户已经登录，并且应用程序中存在一个名为 token 的状态数据，则显示一个包含 class 为 "loginin" 的 div 元素。

使用ajax请求成功返回的数据替换下面代码中的imge_list <div class="row"> {% for imge in imge_list %} {% if not class_name or imge.class_name == class_name %} <div class="col-md-6" id="imge_id" style="width: 310px"> <div class="thumbnail"> <p></p> <form action="{% url 'delete_image' %}" method="POST"> {% csrf_token %} <input type="hidden" name="image_id" value="{{ imge.id }}"> <button type="submit" class="btn btn-sm pull-right" id="delete-button">删除</button> </form> <span class="label label-primary" style="font-size: 20px;">类别</span> <span style="font-size: 20px;">{{ imge.class_name }}</span> <span class="label label-success pull-right" style="font-size: 5px;">{{ imge.confidence }}</span> <p></p> <img src="{{ imge.result_image }}" class="img-rounded" alt="..." height="300px" width="300px"> <span class="label label-info">坐标(xywh):</span> <br>{{ imge.location }}<br> <span class="label label-danger">消耗时间:</span> {{ imge.comsume_time }}<br> <span class="label label-success">预测日期:</span> {{ imge.create_time|date:"Y-m-d:h:i:s" }} </div> </div> {% endif %} {% endfor %} </div>

Assuming that the returned data is a list of image objects, you can use the following code to replace the existing code:

<div class="row" id="imge_list">
{% for imge in imge_list %}
  {% if not class_name or imge.class_name == class_name %}
    <div class="col-md-6" id="imge_id" style="width: 310px">
      <div class="thumbnail">
        <p></p>
        <form action="{% url 'delete_image' %}" method="POST">
          {% csrf_token %}
          <input type="hidden" name="image_id" value="{{ imge.id }}">
          <button type="submit" class="btn btn-sm pull-right" id="delete-button">删除</button>
        </form>
        <span class="label label-primary" style="font-size: 20px;">类别</span>
        <span style="font-size: 20px;">{{ imge.class_name }}</span>
        <span class="label label-success pull-right" style="font-size: 5px;">{{ imge.confidence }}</span>
        <p></p>
        <img src="{{ imge.result_image }}" class="img-rounded" alt="..." height="300px" width="300px">
        <span class="label label-info">坐标(xywh):</span> <br>{{ imge.location }}<br> 
        <span class="label label-danger">消耗时间:</span> {{ imge.comsume_time }}<br> 
        <span class="label label-success">预测日期:</span> {{ imge.create_time|date:"Y-m-d:h:i:s" }}
      </div>
    </div>
  {% endif %}
{% empty %}
  <p>No images found.</p>
{% endfor %}
</div>

You will need to make sure that the returned data is in the correct format and that the `imge_list` variable is properly updated with the new data. You should also add an `id` attribute to the `div` element that contains the image list (`<div class="row" id="imge_list">`) so that you can reference it in your AJAX call.

使用ajax请求成功返回的数据替换下面代码中的imge_list，并给出ajax的代码 <div class="row"> {% for imge in imge_list %} {% if not class_name or imge.class_name == class_name %} <div class="col-md-6" id="imge_id" style="width: 310px"> <div class="thumbnail"> <p></p> <form action="{% url 'delete_image' %}" method="POST"> {% csrf_token %} <input type="hidden" name="image_id" value="{{ imge.id }}"> <button type="submit" class="btn btn-sm pull-right" id="delete-button">删除</button> </form> <span class="label label-primary" style="font-size: 20px;">类别</span> <span style="font-size: 20px;">{{ imge.class_name }}</span> <span class="label label-success pull-right" style="font-size: 5px;">{{ imge.confidence }}</span> <p></p> <img src="{{ imge.result_image }}" class="img-rounded" alt="..." height="300px" width="300px"> <span class="label label-info">坐标(xywh):</span> <br>{{ imge.location }}<br> <span class="label label-danger">消耗时间:</span> {{ imge.comsume_time }}<br> <span class="label label-success">预测日期:</span> {{ imge.c
