从点击的元素 Django 获取数据

[英]Get data from clicked elements Django

我有一个页面,用户可以在其中将 select 人添加到他的团队中。 页面的一侧是 select 的人员列表。 当用户单击添加到团队时,它会转到我们拥有所选人员列表的右侧。

我不明白如何从 django 的视图中获取所选一侧的数据。

例如左边:

<div class="card-body" id="team-list">                   
   <p class="card-text">Select today's teammates:</p>
   <ul class="list-group list-group-flush">
      {% for tech in techs %}
         <li class="list-group-item">
            <span class="name" name="{{tech.id}}">{{tech.name}}</span>
            <span class="move" style="float: right;">Add to the team</span>
         </li>
      {% endfor %}

在右边:

<div class="card-body" id="selected-list">
  <h3 class="title">You have selected the following teammates for today: </h3>
  <ul class="list-group list-group-flush" style="list-style-type: none;">

  </ul>
</div>

点击由一个小的 js 点击事件处理,如下所示:

    var selected = document.querySelector('#selected-list ul');
    var team = document.querySelector('#team-list ul');
function clickHandlerTeam(e){


        if(e.target.classList.contains('move')){
            if (e.target.textContent == 'Add to the team'){
                console.log('changing add');
                e.target.textContent ='Remove from the team';
                selected.appendChild(e.target.parentNode);
            } else {
                console.log('changing remove');
                e.target.textContent = 'Add to the team';
                team.appendChild(e.target.parentNode);
            }    

        console.log('****************');

        }
        return;
}

谢谢你的帮助

{{ selected_techs=[] }}
<div class="card-body" id="team-list">                   
   <p class="card-text">Select today's teammates:</p>
   <ul class="list-group list-group-flush">
      {% for tech in techs %}
         <li class="list-group-item">
            <span class="name" name="{{tech.id}}">{{tech.name}}</span>
            <span class="move" onclick="{{ selected_techs.append(tech) }}" style="float: right;">Add to the team</span>
         </li>
      {% endfor %}
</ul>
</p>
</div>

<div class="card-body" id="selected-list">
  <h3 class="title">You have selected the following teammates for today: </h3>
  <ul class="list-group list-group-flush" style="list-style-type: none;">
      {% for tech in selected_techs %}
         <li class="list-group-item">
            <span class="name" name="{{tech.id}}">{{tech.name}}</span>
         </li>
      {% endfor %}
  </ul>
</div>

我认为这应该可以解决您的问题。 只记得添加

尝试这个

{% with selected_techs=[] %}
<div class="card-body" id="team-list">                   
   <p class="card-text">Select today's teammates:</p>
   <ul class="list-group list-group-flush">
      {% for tech in techs %}
         <li class="list-group-item">
            <span class="name" name="{{tech.id}}">{{tech.name}}</span>
            <span class="move" onclick="{% selected_techs.append(tech) %}" style="float: right;">Add to the team</span>
         </li>
      {% endfor %}
</ul>
</p>
</div>

<div class="card-body" id="selected-list">
  <h3 class="title">You have selected the following teammates for today: </h3>
  <ul class="list-group list-group-flush" style="list-style-type: none;">
      {% for tech in selected_techs %}
         <li class="list-group-item">
            <span class="name" name="{{tech.id}}">{{tech.name}}</span>
         </li>
      {% endfor %}
  </ul>
</div>
{% endwith %}

我找到了我的解决方案。 我为模板中的每个元素添加了一个表单标签,并删除了 ul,将其替换为值为 tech.id 的隐藏输入,并替换了用户过去通过按钮单击的 spans 标签。 然后通过获取 id 使用 views.py 处理它。
