我想根据onclick表值预先选择下拉选项，同时导航到下拉选项的另一页。
下面是代码
app.py

@app.route('/userinfo',methods=["POST","GET"])
def userinfo():
    result = cursor.execute("SELECT * FROM user ORDER BY id")
    user= cursor.fetchall()
    result1 = cursor.execute("SELECT * FROM header ORDER BY id ")
    header = cursor.fetchall()
    return render_template('userinfo.html', user= user, result1=result1)

userinfo.html

<div class="form-group">
      <div class="cols-sm-10">
        <h5>user onfo </h5>
          <select name="name1" class="teamForm" id="teamDropdown" type="text" placeholder="Select projects">
            {% for i in user %}
                <option id="{{ i.id }}" value= "{{ i.id }}">{{ i.name }}</option>
            {% endfor %}
          </select>
          <select name="tasks" class="teamForm2" id="teamDropdown1" type="text" method="POST">
            {% for j in header %}
            <option id="{{ j.id }}" value= "{{ j.header1 }}" selected>{{j.header1 }}</option>
            <option id="{{ j.id }}" value= "{{ j.header2 }}">{{j.header2 }}</option>
            <option id="{{ j.id }}" value= "{{ j.header3 }}" selected>{{j.header3 }}</option>
            <option id="{{ j.id }}" value= "{{ j.header4 }}" selected>{{j.header4 }}</option>                
            {% endfor %}                  
          </select>
    </div>
</div>

index.html

<thead>
  {% for row in header %}
   <tr>
      <th data-pk="{{row.id}}">{{row.id}}</th>
      <th data-pk={{row.id}}">{{row.name}}</th>
      <th data-pk="{{row.id}}">{{row.date}}</th>
      <th data-pk="{{row.id}}">{{row.header1}}</th>
      <th data-pk="{{row.id}}">{{row.header2}}</th>
      <th data-pk="{{row.id}}">{{row.header3}}</th>
    </tr>
  {% endfor %}
 </thead>
<tbody>
{% for row in emp %}
<tr>
  <td data-pk="{{row.id}}">{{row.id}}</td>
  <td data-name="name" class="name" data-type="text" data-pk="{{row.id}}">{{row.name}}</td>
  <td class="under-limit" onclick="location.href='/userinfo'">{{row.task1}}<i id='{{row.id}}' class="fainfo fa fa-info-circle" title=" " aria-hidden="true"></i></td>
  <td class="under-limit" onclick="location.href='/userinfo'">{{row.task2}}<i class="fatask2 fa fa-info-circle" id='{{row.id}}' title=" " aria-hidden="true"></i></td>
  <td class="under-limit" onclick="location.href='/userinfo'">{{row.task3}}<i class="fatask3 fa fa-info-circle" id='{{row.id}}' title=" " aria-hidden="true"></i></td>
</tr>
 {% endfor %}
{/tbody>

单击表格单元格时，根据选定的行和列，必须选择下拉选项，同时导航到另一个页面。我试着用jquery，但做不到。谁能帮我一下吗。
