  // 绑定点击事件，通过传递参数来触发不同的操作
  $("#username_set, #username_set_a").click(function () {
    showModal("username");
  });

  $("#email_set, #email_set_a").click(function () {
    showModal("email");
  });

  $("#mobile_set, #mobile_set_a").click(function () {
    showModal("mobile");
  });

  $("#set_password, #set_password_a").click(function () {
    showModal("password");
  });

  function showModal(type) {
    // 通过判断type的值来触发不同的方法
    switch (type) {
      case "username":
        setUsernameModel.modal("show");
        break;
      case "email":
        setEmailModel.modal("show");
        break;
      case "mobile":
        setMobileModel.modal("show");
        break;
      case "password":
        setPasswordModel.modal("show");
        break;
      default:
        // 如果有其他类型，可以在这里处理
        break;
    }
  }
});

                }
            })

【四】发送Ajax请求传递数据未优化版本

// 提取公共部分，减少重复代码
function sendAjaxRequest(url, dataKey, successCallback, errorCallback) {
    $.ajax({
        url: url,
        type: "post",
        data: {
            ...dataKey,

                // 刷新页面
                alert(result.message);
                window.location.reload();
            } else {
                errorCallback(result.message[dataKey][0]);
            }

}

$('#id_edit_username').click(function () {
    const url = "/user/{{ request.user.username }}/set_username/";
    const dataKey = {
        "new_username": $("#id_new_username").val(),
    };
    sendAjaxRequest(url, dataKey, function() {}, function (errorMessage) {

    };
    sendAjaxRequest(url, dataKey, function() {}, function (errorMessage) {
        $("#id_pwd_error").text(errorMessage);
    });
});

【五】后端接收需要修改的数据未优化

def set_info(request, **kwargs):
    user_obj = models.User.objects.filter(username=request.user).first()
    if not user_obj:
        return render(request, 'error.html')
    if kwargs:
        condition = kwargs.get('condition')
    else:
        return render(request, 'error.html')
    if request.is_ajax():
        if request.method == 'POST':
            back_dict = {"code": 1000, "message": ""}
            form_obj = None
            params_new = None
            if condition == "set_username":
                params_new = request.POST.get('new_username')
                form_obj = MyUsernameForm()
                form_obj = MyUsernameForm(request.POST)
                user_obj.username = params_new
            elif condition == "set_email":
                params_new = request.POST.get('new_email')
                form_obj = MyEmailForm()
                form_obj = MyEmailForm(request.POST)
                user_obj.email = params_new
            elif condition == "set_mobile":
                params_new = request.POST.get('new_mobile')
                form_obj = MyMobileForm()
                form_obj = MyMobileForm(request.POST)
                user_obj.mobile = params_new
            if form_obj.is_valid():

                user_obj.save()
                back_dict["message"] = "设置成功"

            else:
                back_dict["code"] = 1003
                back_dict["message"] = form_obj.errors
                print(back_dict)
            return JsonResponse(back_dict)

【六】后端接收需要修改的数据优化之根据不同的条件执行相应的操作

def set_info(request, **kwargs):
    # 获取当前用户对象
    user_obj = models.User.objects.filter(username=request.user).first()
    
    # 如果用户对象不存在，则返回错误页面
    if not user_obj:
