  8. * @name NavController
  9. * @description
  10. *
  11. * NavController is the base class for navigation controller components like
  12. * [`Nav`](../../components/nav/Nav/) and [`Tab`](../../components/tabs/Tab/). You use navigation controllers
  13. * to navigate to [pages](#view-creation) in your app. At a basic level, a
  14. * navigation controller is an array of pages representing a particular history
  15. * (of a Tab for example). This array can be manipulated to navigate throughout
  16. * an app by pushing and popping pages or inserting and removing them at
  17. * arbitrary locations in history.
  18. *
  19. * The current page is the last one in the array, or the top of the stack if we
  20. * think of it that way. [Pushing](#push) a new page onto the top of the
  21. * navigation stack causes the new page to be animated in, while [popping](#pop)
  22. * the current page will navigate to the previous page in the stack.
  23. *
  24. * Unless you are using a directive like [NavPush](../../components/nav/NavPush/), or need a
  25. * specific NavController, most times you will inject and use a reference to the
  26. * nearest NavController to manipulate the navigation stack.
  27. *
  28. * ## Basic usage
  29. * The simplest way to navigate through an app is to create and initialize a new
  30. * nav controller using the `<ion-nav>` component. `ion-nav` extends the `NavController`
  31. * class.
  32. *
  33. * ```typescript
  34. * import { Component } from `@angular/core`;
  35. * import { StartPage } from './start-page';
  36. *
  37. * @Component(
  38. * template: `<ion-nav [root]="rootPage"></ion-nav>`
  39. * })
  40. * class MyApp {
  41. * // set the rootPage to the first page we want displayed
  42. * public rootPage: any = StartPage;
  43. *
  44. * constructor(){
  45. * }
  46. * }
  47. *
  48. * ```
  49. *
  50. * ### Injecting NavController
  51. * Injecting NavController will always get you an instance of the nearest
  52. * NavController, regardless of whether it is a Tab or a Nav.
  53. *
  54. * Behind the scenes, when Ionic instantiates a new NavController, it creates an
  55. * injector with NavController bound to that instance (usually either a Nav or
  56. * Tab) and adds the injector to its own providers. For more information on
  57. * providers and dependency injection, see [Dependency Injection](https://angular.io/docs/ts/latest/guide/dependency-injection.html).
  58. *
  59. * Instead, you can inject NavController and know that it is the correct
  60. * navigation controller for most situations (for more advanced situations, see
  61. * [Menu](../../menu/Menu/) and [Tab](../../tab/Tab/)).
  62. *
  63. * ```ts
  64. * import { NavController } from 'ionic-angular';
  65. *
  66. * class MyComponent {
  67. * constructor(public navCtrl: NavController) {
  68. *
  69. * }
  70. * }
  71. * ```
  72. *
  73. * ### Navigating from the Root component
  74. * What if you want to control navigation from your root app component?
  75. * You can't inject `NavController` because any components that are navigation
  76. * controllers are _children_ of the root component so they aren't available
  77. * to be injected.
  78. *
  79. * By adding a reference variable to the `ion-nav`, you can use `@ViewChild` to
  80. * get an instance of the `Nav` component, which is a navigation controller
  81. * (it extends `NavController`):
  82. *
  83. * ```typescript
  84. *
  85. * import { Component, ViewChild } from '@angular/core';
  86. * import { NavController } from 'ionic-angular';
  87. *
  88. * @Component({
  89. * template: '<ion-nav #myNav [root]="rootPage"></ion-nav>'
  90. * })
  91. * export class MyApp {
  92. * @ViewChild('myNav') nav: NavController
  93. * public rootPage: any = TabsPage;
  94. *
  95. * // Wait for the components in MyApp's template to be initialized
  96. * // In this case, we are waiting for the Nav with reference variable of "#myNav"
  97. * ngOnInit() {
  98. * // Let's navigate from TabsPage to Page1
  99. * this.nav.push(Page1);
  100. * }
  101. * }
  102. * ```
  103. *
  104. * ### Navigating from an Overlay Component
  105. * What if you wanted to navigate from an overlay component (popover, modal, alert, etc)?
  106. * In this example, we've displayed a popover in our app. From the popover, we'll get a
  107. * reference of the root `NavController` in our app, using the `getRootNav()` method.
  108. *
  109. *
  110. * ```typescript
  111. * import { Component } from '@angular/core';
  112. * import { App, ViewController } from 'ionic-angular';
  113. *
  114. * @Component({
  115. * template: `
  116. * <ion-content>
  117. * <h1>My PopoverPage</h1>
  118. * <button ion-button (click)="pushPage()">Call pushPage</button>
  119. * </ion-content>
  120. * `
  121. * })
  122. * class PopoverPage {
  123. * constructor(
  124. * public viewCtrl: ViewController
  125. * public appCtrl: App
  126. * ) {}
  127. *
  128. * pushPage() {
  129. * this.viewCtrl.dismiss();
  130. * this.appCtrl.getRootNav().push(SecondPage);
  131. * }
  132. * }
  133. *```
  134. *
  135. *
  136. * ## View creation
  137. * Views are created when they are added to the navigation stack. For methods
  138. * like [push()](#push), the NavController takes any component class that is
  139. * decorated with `@Component` as its first argument. The NavController then
  140. * compiles that component, adds it to the app and animates it into view.
  141. *
  142. * By default, pages are cached and left in the DOM if they are navigated away
  143. * from but still in the navigation stack (the exiting page on a `push()` for
  144. * example). They are destroyed when removed from the navigation stack (on
  145. * [pop()](#pop) or [setRoot()](#setRoot)).
  146. *
  147. * ## Pushing a View
  148. * To push a new view onto the navigation stack, use the `push` method.
  149. * If the page has an [`<ion-navbar>`](../../navbar/Navbar/),
  150. * a back button will automatically be added to the pushed view.
  151. *
  152. * Data can also be passed to a view by passing an object to the `push` method.
  153. * The pushed view can then receive the data by accessing it via the `NavParams`
  154. * class.
  155. *
  156. * ```typescript
  157. * import { Component } from '@angular/core';
  158. * import { NavController } from 'ionic-angular';
  159. * import { OtherPage } from './other-page';
  160. * @Component({
  161. * template: `
  162. * <ion-header>
  163. * <ion-navbar>
  164. * <ion-title>Login</ion-title>
  165. * </ion-navbar>
  166. * </ion-header>
  167. *
  168. * <ion-content>
  169. * <button ion-button (click)="pushPage()">
  170. * Go to OtherPage
  171. * </button>
  172. * </ion-content>
  173. * `
  174. * })
  175. * export class StartPage {
  176. * constructor(public navCtrl: NavController) {
  177. * }
  178. *
  179. * pushPage(){
  180. * // push another page onto the navigation stack
  181. * // causing the nav controller to transition to the new page
  182. * // optional data can also be passed to the pushed page.
  183. * this.navCtrl.push(OtherPage, {
  184. * id: "123",
  185. * name: "Carl"
  186. * });
  187. * }
  188. * }
  189. *
  190. * import { NavParams } from 'ionic-angular';
  191. *
  192. * @Component({
  193. * template: `
  194. * <ion-header>
  195. * <ion-navbar>
  196. * <ion-title>Other Page</ion-title>
  197. * </ion-navbar>
  198. * </ion-header>
  199. * <ion-content>I'm the other page!</ion-content>`
  200. * })
  201. * class OtherPage {
  202. * constructor(private navParams: NavParams) {
  203. * let id = navParams.get('id');
  204. * let name = navParams.get('name');
  205. * }
  206. * }
  207. * ```
  208. *
  209. * ## Removing a view
  210. * To remove a view from the stack, use the `pop` method.
  211. * Popping a view will transition to the previous view.
  212. *
  213. * ```ts
  214. * import { Component } from '@angular/core';
  215. * import { NavController } from 'ionic-angular';
  216. *
  217. * @Component({
  218. * template: `
  219. * <ion-header>
  220. * <ion-navbar>
  221. * <ion-title>Other Page</ion-title>
  222. * </ion-navbar>
  223. * </ion-header>
  224. * <ion-content>I'm the other page!</ion-content>`
  225. * })
  226. * class OtherPage {
  227. * constructor(public navCtrl: NavController ){
  228. * }
  229. *
  230. * popView(){
  231. * this.navCtrl.pop();
  232. * }
  233. * }
  234. * ```
  235. *
  236. * ## Lifecycle events
  237. * Lifecycle events are fired during various stages of navigation. They can be
  238. * defined in any component type which is pushed/popped from a `NavController`.
  239. *
  240. * ```ts
  241. * import { Component } from '@angular/core';
  242. *
  243. * @Component({
  244. * template: 'Hello World'
  245. * })
  246. * class HelloWorld {
  247. * ionViewDidLoad() {
  248. * console.log("I'm alive!");
  249. * }
  250. * ionViewWillLeave() {
  251. * console.log("Looks like I'm about to leave :(");
  252. * }
  253. * }
  254. * ```
  255. *
  256. * | Page Event | Returns | Description |
  257. * |---------------------|-----------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
  258. * | `ionViewDidLoad` | void | Runs when the page has loaded. This event only happens once per page being created. If a page leaves but is cached, then this event will not fire again on a subsequent viewing. The `ionViewDidLoad` event is good place to put your setup code for the page. |
  259. * | `ionViewWillEnter` | void | Runs when the page is about to enter and become the active page. |
  260. * | `ionViewDidEnter` | void | Runs when the page has fully entered and is now the active page. This event will fire, whether it was the first load or a cached page. |
  261. * | `ionViewWillLeave` | void | Runs when the page is about to leave and no longer be the active page. |
  262. * | `ionViewDidLeave` | void | Runs when the page has finished leaving and is no longer the active page. |
  263. * | `ionViewWillUnload` | void | Runs when the page is about to be destroyed and have its elements removed. |
  264. * | `ionViewCanEnter` | boolean/Promise&lt;void&gt; | Runs before the view can enter. This can be used as a sort of "guard" in authenticated views where you need to check permissions before the view can enter |
  265. * | `ionViewCanLeave` | boolean/Promise&lt;void&gt; | Runs before the view can leave. This can be used as a sort of "guard" in authenticated views where you need to check permissions before the view can leave |
  266. *
  267. *
  268. * ## Nav Guards
  269. *
  270. * In some cases, a developer should be able to control views leaving and entering. To allow for this, NavController has the `ionViewCanEnter` and `ionViewCanLeave` methods.
  271. * Similar to Angular route guards, but are more integrated with NavController. For example, if you wanted to prevent a user from leaving a view:
  272. *
  273. * ```ts
  274. * export class MyClass{
  275. * constructor(
  276. * public navCtrl: NavController
  277. * ){}
  278. *
  279. * pushPage(){
  280. * this.navCtrl.push(DetailPage);
  281. * }
  282. *
  283. * ionViewCanLeave(): boolean{
  284. * // here we can either return true or false
  285. * // depending on if we want to leave this view
  286. * if(isValid(randomValue)){
  287. * return true;
  288. * } else {
  289. * return false;
  290. * }
  291. * }
  292. * }
  293. * ```
  294. *
  295. * We need to make sure that our `navCtrl.push` has a catch in order to catch the and handle the error.
  296. * If you need to prevent a view from entering, you can do the same thing
  297. *
  298. * ```ts
  299. * export class MyClass{
  300. * constructor(
  301. * public navCtrl: NavController
  302. * ){}
  303. *
  304. * pushPage(){
  305. * this.navCtrl.push(DetailPage);
  306. * }
  307. *
  308. * }
  309. *
  310. * export class DetailPage(){
  311. * constructor(
  312. * public navCtrl: NavController
  313. * ){}
  314. * ionViewCanEnter(): boolean{
  315. * // here we can either return true or false
  316. * // depending on if we want to enter this view
  317. * if(isValid(randomValue)){
  318. * return true;
  319. * } else {
  320. * return false;
  321. * }
  322. * }
  323. * }
  324. * ```
  325. *
  326. * Similar to `ionViewCanLeave` we still need a catch on the original `navCtrl.push` in order to handle it properly.
  327. * When handling the back button in the `ion-navbar`, the catch is already taken care of for you by the framework.
  328. *
  329. * ## NavOptions
  330. *
  331. * Some methods on `NavController` allow for customizing the current transition.
  332. * To do this, we can pass an object with the modified properites.
  333. *
  334. *
  335. * | Property | Value | Description |
  336. * |-----------|-----------|------------------------------------------------------------------------------------------------------------|
  337. * | animate | `boolean` | Whether or not the transition should animate. |
  338. * | animation | `string` | What kind of animation should be used. |
  339. * | direction | `string` | The conceptual direction the user is navigating. For example, is the user navigating `forward`, or `back`? |
  340. * | duration | `number` | The length in milliseconds the animation should take. |
  341. * | easing | `string` | The easing for the animation. |
  342. *
  343. * The property 'animation' understands the following values: `md-transition`, `ios-transition` and `wp-transition`.
