ajax 前后端交互

前端

<script>
    $('#id_edit').click(function () {
        $.ajax({
            url:'/set_password/',
            type:'post',
            data:{
                'old_password':$('#id_old_password').val(),
                'new_password':$('#id_new_password').val(),
                'confirm_password':$('#id_confirm_password').val(),
                'csrfmiddlewaretoken':'{{ csrf_token }}',

            },
            success:function(args){
                if (args.code==1000){
                   // window.location.href='/login/'
                    window.location.reload()
                }else{
                    $('#id_password_error').text(args.msg)
                }

            }
        })


    })

　　后端

                    request.user.set_password(new_password)  # 如果密码相同则设置密码并保存
                    request.user.save()
                    back_dic['msg'] = '修改成功'

                    back_dic['msg'] = '两次密码不一致'
            else:

                back_dic['msg'] = '原密码错误'

    return JsonResponse(back_dic)
