flask模板循环输出及间隔出现广告

小土

在html模板中的代码，直接输出内容时的简写

{% for result in result %} 
		<div class="row message_details">
                    <div class="col-md-3 sender">
                        <label>Sender</label><br>
                        {{ result['fromnum'] }}
                    </div>
                    <div class="col-md-6 msg">
                        <label>Message</label><br>
                       {{ result['content'] }}
                    </div>
                    <div class="col-md-3 time">
                        <label>Time</label><br>
                        {{ result['gettime'] }}
                    </div>
                </div>            
  
{% endfor %}

需要间隔出现广告时

{% for i in range(result|length) %} 
		<div class="row message_details">
                    <div class="col-md-3 sender">
                        <label>Sender</label><br>
                        {{ result[i]['fromnum'] }}
                    </div>
                    <div class="col-md-6 msg">
                        <label>Message</label><br>
                       {{ result[i]['content'] }}
                    </div>
                    <div class="col-md-3 time">
                        <label>Time</label><br>
                        {{ result[i]['gettime'] }}
                    </div>
                </div>            
            {% if i  == 3 %}  
                <div>123</div>
            {% endif %}
 {% endfor %}
