Modal is a temporary UI that is displayed on top of your current page. This is often used for login, signup, editing existing options and selecting options. Let us look in to a simple example with modals used. To begin with we are creating an ionic blank project. Let us create a simple modal displa...

We now know how to create a modal. But what if we want to pass some data from modal to our home page. To do so, let us look into an example with modal as Register page passing parameters to parent page. Register.html <ion-header> <ion-toolbar> <ion-title> Login ...

Passing parameters to a modal is similar to how we pass values to a NavController. To do so, we are altering our list in home.html to open a modal when clicking a list item and passing the required parameters as a second argument to the create method. Home.html <ion-list> <ion-item ...

class my_model(models.Model): _name = "my.model" name = fields.Char('Name') @api.multi def foo_manipulate_records_1(self): """ function returns list of tuples (id,name) """ return [(i.id,i.name) for i in self] @...

Examples below demonstrate how to call Python function from JavaScript in Odoo 8. In the examples we call methods of my_model described early on this page. We assume that in the following examples "list_of_ids" variable contains list(array) of ids of existing records of "my.model&quo...

defmodule MyModule do @my_favorite_number 13 @use_snake_case "This is a string (use double-quotes)" end These are only accessible from within this module.

First step is create navigation interface which we will use on view model: public interface IViewNavigationService { void Initialize(INavigation navigation, SuperMapper navigationMapper); Task NavigateToAsync(object navigationSource, object parameter = null); Task GoBackAsync(); } ...

You'll first send the user to the Twitch authorization endpoint. This URL is made up of a the base authorization URL (https://api.twitch.tv/kraken/oauth2/authorize) and query string parameters that define what you're requesting. The required parameters are response_type, client_id, redirect_uri, and...

When the user goes to the authorization endpoint, they will be asked to give your application permission to the scopes that you've requested. They can decline this, so you must make sure to take that into consideration in your code. After they've allowed your application access, the user will be red...

Now that you have an authorization code, you can make a POST to the token endpoint (https://api.twitch.tv/kraken/oauth2/token) to get an OAuth token. You will receive a JSON-encoded access token, refresh token, and a list of the scopes approved by the user. You can now use that token to make authent...

// this is the static platform browser, the usual counterpart is @angular/platform-browser-dynamic. import { platformBrowser } from '@angular/platform-browser'; // this is generated by the angular compiler import { AppModuleNgFactory } from './ngfactory/app/app.module.ngfactory'; // note the...

When user enters an URL, for example: http://example-website.com/Example/HelloWorld, MVC application will use the routing rules to parse this url and extract the subpath, that will determine the controller, action and possible parameters. For the above url, the result will be /Example/HelloWorld, wh...

If there would be another value in the URL like: /Example/ProcessInput/2, the routing rules will threat the last number as a parameter passed into the action ProcessInput of controller Example. public ActionResult ProcessInput(int number) { ViewData["OutputMessage"] = string.format(...

using System; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { var foo = new Dependency(); var bar = new ClassWithDependency(); bar.DoSomething(foo); //Inject dependency as method parameter ...

In this example I will go through the implementation of the perceptron model in C++ so that you can get a better idea of how it works. First things first it is a good practice to write down a simple algorithm of what we want to do. Algorithm: Make a the vector for the weights and initialize it ...

This example shows how to find number of days between two dates. A date is specified by year/month/day of month, and additionally hour/minute/second. Program calculates number of days in years since 2000. #include <iostream> #include <string> #include <chrono> #include <cti...
