Flask 如何在WTForms中将值设置为隐藏整数字段

我有一个表单，需要取1

integer

value。此整数值将是与

html

表中的行关联的id

template.html

{% block content %}
<div id="formContainer" class="center top">
  <p class="lead">Select simulation session </p>
  {% if simulationSessions %}
    <table class="table table-striped">
    <thead>
      <tr>
        <th></th>
        <th>#</th>
        <th>Label</th>
        <th>Date</th>
      </tr>
    </thead>
    <tbody>
    {% for simulationSession in simulationSessions %}
      <tr>
        <td><input id="id-{{ simulationSession.id }}" name="idRadio" type="radio" value="{{ simulationSession.id }}"> </td>
        <td>{{ simulationSession.id }}</td>
        <td>{{ simulationSession.label }}</td>
        <td>{{ simulationSession.date.strftime('%d-%m-%y %H:%M') }}</td>
      </tr>
    {% endfor %}
    </tbody>
  </table>
  <button type="button" class="btn btn-sm btn-success">Analyse</button>
  {% else %}
    <div class="alert alert-danger" role="alert">
      <strong>Oopsadazy!</strong> No simulations are registered in the database for this user. You need to run a simulation session before analyzing it!
    </div>
  {% endif %} 
</div>
{% endblock %} 

我的问题是，提交表单后，如何从所选单选按钮获取值并将其用作隐藏整数字段的数据

这可以在html中的脚本中使用类似的东西来完成吗？（本文件未编译）

视图的外观如下所示：

view.py

class SimulationSessionSelectionForm(Form):
  simulationSessoinId = IntegerField('simulationSessoinId', validators=[DataRequired()], widget=HiddenInput())

@app.route('/dashboard', methods=['GET', 'POST']) 
@login_required
def dashboard():
  form = SimulationSessionSelectionForm()
  if form.validate_on_submit():
    redirect('/somewhere')
  userkey = models.User.query.filter_by(id = current_user.get_id()).first().userKey
  userSimulationSessions = models.SimulationSession.query.filter_by(userKey = userkey).all()
  simulationSessions = []
  simulationSessionIds = []
  for simulation in userSimulationSessions:
    simulationSessions.append({'id' : simulation.sessionID, 'label' : simulation.label, 'date' : simulation.date})
    simulationSessionIds.append(simulation.sessionID)
  return render_template("dashboard.html", simulationSessions = simulationSessions, form = form)

模板中的此行将隐藏字段（和csfr令牌）添加到

我想只要触发单选按钮更改事件，我就可以通过一些
jquery
脚本设置隐藏的
IntegerField
的值。为此，我使用了以下代码：

<script>
    $( document ).ready(function() {
      $('input[type=radio][name=idRadio]').change(function() {
        $('#simulationSessoinId').val(this.value)       
      });
    });

</script> 


$（文档）.ready（函数（）{
$（'input[type=radio][name=idRadio]'）。更改（函数（）{
$（'#SimulationSessOID'）.val（this.value）
});
});

{{ form.hidden_tag() }}

<script>
    $( document ).ready(function() {
      $('input[type=radio][name=idRadio]').change(function() {
        $('#simulationSessoinId').val(this.value)       
      });
    });

</script>
