This delay was initially introduced so the browser can know whether the user wants to + * double-tap to zoom in on the webpage. Basically, the browser waits roughly 300ms to see if + * the user is double-tapping, or just tapping on the display once. + * + * Out of the box, Ionic automatically removes the 300ms delay in order to make Ionic apps + * feel more "native" like. Resultingly, other solutions such as + * [fastclick](https://github.com/ftlabs/fastclick) and Angular's + * [ngTouch](https://docs.angularjs.org/api/ngTouch) should not be included, to avoid conflicts. + * + * Some browsers already remove the delay with certain settings, such as the CSS property + * `touch-events: none` or with specific meta tag viewport values. However, each of these + * browsers still handle clicks differently, such as when to fire off or cancel the event + * (like scrolling when the target is a button, or holding a button down). + * For browsers that already remove the 300ms delay, consider Ionic's tap system as a way to + * normalize how clicks are handled across the various devices so there's an expected response + * no matter what the device, platform or version. Additionally, Ionic will prevent + * ghostclicks which even browsers that remove the delay still experience. + * + * In some cases, third-party libraries may also be working with touch events which can interfere + * with the tap system. For example, mapping libraries like Google or Leaflet Maps often implement + * a touch detection system which conflicts with Ionic's tap system. + * + * ### Disabling the tap system + * + * To disable the tap for an element and all of its children elements, + * add the attribute `data-tap-disabled="true"`. + * + * ```html + * <div data-tap-disabled="true"> + * <div id="google-map"></div> + * </div> + * ``` + * + * ### Additional Notes: + * + * - Ionic tap works with Ionic's JavaScript scrolling + * - Elements can come and go from the DOM and Ionic tap doesn't keep adding and removing + * listeners + * - No "tap delay" after the first "tap" (you can tap as fast as you want, they all click) + * - Minimal events listeners, only being added to document + * - Correct focus in/out on each input type (select, textearea, range) on each platform/device + * - Shows and hides virtual keyboard correctly for each platform/device + * - Works with labels surrounding inputs + * - Does not fire off a click if the user moves the pointer too far + * - Adds and removes an 'activated' css class + * - Multiple [unit tests](https://github.com/driftyco/ionic/blob/master/test/unit/utils/tap.unit.js) for each scenario + * + */ +/* + + IONIC TAP + --------------- + - Both touch and mouse events are added to the document.body on DOM ready + - If a touch event happens, it does not use mouse event listeners + - On touchend, if the distance between start and end was small, trigger a click + - In the triggered click event, add a 'isIonicTap' property + - The triggered click receives the same x,y coordinates as as the end event + - On document.body click listener (with useCapture=true), only allow clicks with 'isIonicTap' + - Triggering clicks with mouse events work the same as touch, except with mousedown/mouseup + - Tapping inputs is disabled during scrolling +*/ + +var tapDoc; // the element which the listeners are on (document.body) +var tapActiveEle; // the element which is active (probably has focus) +var tapEnabledTouchEvents; +var tapMouseResetTimer; +var tapPointerMoved; +var tapPointerStart; +var tapTouchFocusedInput; +var tapLastTouchTarget; +var tapTouchMoveListener = 'touchmove'; + +// how much the coordinates can be off between start/end, but still a click +var TAP_RELEASE_TOLERANCE = 12; // default tolerance +var TAP_RELEASE_BUTTON_TOLERANCE = 50; // button elements should have a larger tolerance + +var tapEventListeners = { + 'click': tapClickGateKeeper, + + 'mousedown': tapMouseDown, + 'mouseup': tapMouseUp, + 'mousemove': tapMouseMove, + + 'touchstart': tapTouchStart, + 'touchend': tapTouchEnd, + 'touchcancel': tapTouchCancel, + 'touchmove': tapTouchMove, + + 'pointerdown': tapTouchStart, + 'pointerup': tapTouchEnd, + 'pointercancel': tapTouchCancel, + 'pointermove': tapTouchMove, + + 'MSPointerDown': tapTouchStart, + 'MSPointerUp': tapTouchEnd, + 'MSPointerCancel': tapTouchCancel, + 'MSPointerMove': tapTouchMove, + + 'focusin': tapFocusIn, + 'focusout': tapFocusOut +}; + +ionic.tap = { + + register: function(ele) { + tapDoc = ele; + + tapEventListener('click', true, true); + tapEventListener('mouseup'); + tapEventListener('mousedown'); + + if (window.navigator.pointerEnabled) { + tapEventListener('pointerdown'); + tapEventListener('pointerup'); + tapEventListener('pointcancel'); + tapTouchMoveListener = 'pointermove'; + + } else if (window.navigator.msPointerEnabled) { + tapEventListener('MSPointerDown'); + tapEventListener('MSPointerUp'); + tapEventListener('MSPointerCancel'); + tapTouchMoveListener = 'MSPointerMove'; + + } else { + tapEventListener('touchstart'); + tapEventListener('touchend'); + tapEventListener('touchcancel'); + } + + tapEventListener('focusin'); + tapEventListener('focusout'); + + return function() { + for (var type in tapEventListeners) { + tapEventListener(type, false); + } + tapDoc = null; + tapActiveEle = null; + tapEnabledTouchEvents = false; + tapPointerMoved = false; + tapPointerStart = null; + }; + }, + + ignoreScrollStart: function(e) { + return (e.defaultPrevented) || // defaultPrevented has been assigned by another component handling the event + (/^(file|range)$/i).test(e.target.type) || + (e.target.dataset ?

In order for this to work, any focusable elements must be within + * a [Scroll View](http://ionicframework.com/docs/api/directive/ionScroll/) + * or a directive such as [Content](http://ionicframework.com/docs/api/directive/ionContent/) + * that has a Scroll View. + * + * It will also attempt to prevent the native overflow scrolling on focus, + * which can cause layout issues such as pushing headers up and out of view. + * + * The keyboard fixes work best in conjunction with the + * [Ionic Keyboard Plugin](https://github.com/driftyco/ionic-plugins-keyboard), + * although it will perform reasonably well without. However, if you are using + * Cordova there is no reason not to use the plugin. + * + * ### Hide when keyboard shows + * + * To hide an element when the keyboard is open, add the class `hide-on-keyboard-open`. + * + * ```html + * <div class="hide-on-keyboard-open"> + * <div id="google-map"></div> + * </div> + * ``` + * ---------- + * + * ### Plugin Usage + * Information on using the plugin can be found at + * [https://github.com/driftyco/ionic-plugins-keyboard](https://github.com/driftyco/ionic-plugins-keyboard). + * + * ---------- + * + * ### Android Notes + * - If your app is running in fullscreen, i.e. you have + * `<preference name="Fullscreen" value="true" />` in your `config.xml` file + * you will need to set `ionic.Platform.isFullScreen = true` manually. + * + * - You can configure the behavior of the web view when the keyboard shows by setting + * [android:windowSoftInputMode](http://developer.android.com/reference/android/R.attr.html#windowSoftInputMode) + * to either `adjustPan`, `adjustResize` or `adjustNothing` in your app's + * activity in `AndroidManifest.xml`. `adjustResize` is the recommended setting + * for Ionic, but if for some reason you do use `adjustPan` you will need to + * set `ionic.Platform.isFullScreen = true`. + * + * ```xml + * <activity android:windowSoftInputMode="adjustResize"> + * + * ``` + * + * ### iOS Notes + * - If the content of your app (including the header) is being pushed up and + * out of view on input focus, try setting `cordova.plugins.Keyboard.disableScroll(true)`. + * This does **not** disable scrolling in the Ionic scroll view, rather it + * disables the native overflow scrolling that happens automatically as a + * result of focusing on inputs below the keyboard. + * + */ + +/** + * The current viewport height. + */ +var keyboardCurrentViewportHeight = 0; + +/** + * The viewport height when in portrait orientation. + */ +var keyboardPortraitViewportHeight = 0; + +/** + * The viewport height when in landscape orientation. + */ +var keyboardLandscapeViewportHeight = 0; + +/** + * The currently focused input. + */ +var keyboardActiveElement; + +/** + * The scroll view containing the currently focused input. + */ +var scrollView; + +/** + * Timer for the setInterval that polls window.innerHeight to determine whether + * the layout has updated for the keyboard showing/hiding. + */ +var waitForResizeTimer; + +/** + * Sometimes when switching inputs or orientations, focusout will fire before + * focusin, so this timer is for the small setTimeout to determine if we should + * really focusout/hide the keyboard. + */ +var keyboardFocusOutTimer; + +/** + * on Android, orientationchange will fire before the keyboard plugin notifies + * the browser that the keyboard will show/is showing, so this flag indicates + * to nativeShow that there was an orientationChange and we should update + * the viewport height with an accurate keyboard height value + */ +var wasOrientationChange = false; + +/** + * CSS class added to the body indicating the keyboard is open. + */ +var KEYBOARD_OPEN_CSS = 'keyboard-open'; + +/** + * CSS class that indicates a scroll container. + */ +var SCROLL_CONTAINER_CSS = 'scroll-content'; + +/** + * Ionic keyboard namespace. + * @namespace keyboard + */ +ionic.keyboard = { + + /** + * Whether the keyboard is open or not. + */ + isOpen: false, + + /** + * Whether the keyboard is closing or not. + */ + isClosing: false, + + /** + * Whether the keyboard is opening or not. + */ + isOpening: false, + + /** + * The height of the keyboard in pixels, as reported by the keyboard plugin. + * If the plugin is not available, calculated as the difference in + * window.innerHeight after the keyboard has shown. + */ + height: 0, + + /** + * Whether the device is in landscape orientation or not. + */ + isLandscape: false, + + /** + * Hide the keyboard, if it is open. + */ + hide: function() { + if (keyboardHasPlugin()) { + cordova.plugins.Keyboard.close(); + } + keyboardActiveElement && keyboardActiveElement.blur(); + }, + + /** + * An alias for cordova.plugins.Keyboard.show().
