flask多选框怎么实现

一、 文本域和单选按钮

前端 文本域和单选按钮表单获取方法一样

 <form class="form-horizontal" method="post">
    <div class="form-group">
      <label for="username" class="col-sm-2 control-label">Username</label>
      <div class="col-sm-10">
        <input type="text" class="form-control" id="username" name="username" placeholder="Username" autofocus="" >
      </div>
    </div>
....
...
  <div class="row">
        <div class="col-sm-2 col-sm-offset-2">
            <input name="sex" value="M" type="radio"  checked="checked"> 男
        </div>
 <div class="col-sm-2 ">
            <input name="sex" value="F" type="radio"> 女
        </div>
                    
    </div>
</form>

文本

pyhon 后端用request.values.get("name") 去获取

if request.method == "POST":   
    username = request.values.get("username")
    sex = request.values.get("sex")

二、多选按钮checkbox

<div class="row">
    <div class="col-sm-2 ">
        <label>
            <input name="s_option" value="basketball" type="checkbox"> 篮球
        </label>
    </div>
    <div class="col-sm-2 ">
        <label>
        <input name="s_option" value="football" type="checkbox"> 足球
        </label>
    </div>
    <div class="col-sm-2 ">
        <label>
            <input name="s_option" value="badminton"  type="checkbox"> 羽毛球
        </label>
    </div>
</div>
