如何将参数传递给模式弹出窗口? [英] how to pass parameters to modal popup?

问题描述

我正在使用Nativescript应用程序，需要在单击列表项时打开视图.因此，我将必须将该项目的id传递给将在单击列表项目时打开的模式.

I am working on Nativescript application where i need to open view on click of list item. So i will have to pass id of that item to the modal that is about to open on click of list item.

这是我尝试打开模式弹出窗口时的代码:

Here is my code as i tried and for opening modal popup :

var modalPageModule = views.appointmentDetails;
var context = {
  id: args.view.bookingId // i tried this way for passing parameter
};
var fullscreen = true;
page.showModal(modalPageModule, context, function closeCallback(parameters) {
 // Log the user in...

}, fullscreen);

以及用于在模式弹出窗口的控制器上获取参数的代码

And code for getting passed parameter on controller of modal popup

page = args.object;
var gotData = page.navigationContext;
var id = gotData.id;

但返回NaN.

请提出一些将变量传递给模式弹出窗口的方法.

Please suggest some way to pass variable to modal popup.

推荐答案

在XML文件中进行更改后问题已解决

Problem solved after making change in XML file

<Page xmlns="http://schemas.nativescript.org/tns.xsd"
      xmlns:widgets="utils/widgets"
      showingModally="onLoaded">

并在模式控制器中

exports.onLoaded = function(args) {
    var id = args.context.id
