html复选框怎么向后端传值,前端获取checkbox复选框的值 通过数组形式传递

html代码：

应用一组

{% for peopel_1 in peopels_1 %}

{{ peopel_1.name }}

{% endfor %}

应用二组

{% for peopel_2 in peopels_2 %}

{{ peopel_2.name }}

{% endfor %}

提交

js代码：

1 获取已选中的名字并放到数组中

var name_list = [];

$("input[name='people_name']:checked").each(function(){

name_list.push($(this).val)

});

2 利用ajax向后台传递form表单数据

$(".select_people").submit(function(event){

event.preventDefault();  // 阻止默认表单的action功能

var name_list = [];

$("input[name='people_name']:checked").each(function(){

name_list.push($(this).val)

});

data = {'id': 1, 'names': name_list};

$.ajax({

url: "task_mgm/********",

type: "POST",

data: JSON.stringify(data),

contentType: "application/json",  //发送到后台的数据格式

data_type: "json",  // 接收后端返回的数据格式

success: function(resp){

if (resp.error == "OK"){ console.log('分享成功') }

else { console.log('分享失败') }

}

});

})

python后台代码：

1 @task_mgm.route('/taskinfo_share_people', methods=['POST', 'GET'])2 @login_required3 deftaskinfo_share_people_fun():4 datas =request.get_json()5 task_id = datas.get('id')6 sharePeopleList = datas.get('names')7 print(sharePeopleList)8 task =ShareTask()9 if len(sharePeopleList) >0:10 task.taskId =task_id11

12 sharePeopleList = list(set(sharePeopleList)) #去重

13 sharePs = ','.join(sharePeopleList)14 task.sharePeopleTo =sharePs15 task.sharePeopleFrom =current_user.name16 db.session.add(task)17 db.session.commit()18 return jsonify(error='OK', emsg="True")19 else:20 return jsonify(error='NO', emsg="False")
