title : “警告!”,
template : “为何要敲 “+ item + “?”
});
};
});code
在屏幕上快速敲击两次,将触发on-double-tap事件:orm
能够在任何元素上使用这个指令挂接事件监听函数:
示例代码:
<body ng-controller=”ezCtrl”>
<ion-header-bar class=”bar-positive” on-double-tap=”title=’I am double tapped!'”>
<h1 class=”title”>{{title}}</h1>
</ion-header-bar>
<ion-content>
<p ng-include=”‘txt/xiyouji.txt'”></p>
</ion-content>
</body>
js:
angular.module(“ezApp”,[“ionic”])
.controller(“ezCtrl”,function($scope) {
$scope.title = “on-double-tap”;
});
在屏幕上按下手指或鼠标键时,会当即触发on-touch事件;当手指抬起或鼠标键松开时, 会当即触发on-release事件。
能够在任何元素上挂接响应的事件监听函数:
示例代码:
<body ng-controller=”ezCtrl”>
<ion-header-bar class=”bar-positive” ng-class=”[style]”
on-touch=”style=’bar-assertive'” on-release=”style=’bar-positive'”>
<h1 class=”title”>on-touche/on-release</h1>
</ion-header-bar>
<ion-content>
<img src=”img/0021.png”>
</ion-content>
</body>
js:
angular.module(“ezApp”,[“ionic”])
.controller(“ezCtrl”,function($scope) {
});
在屏幕上按住并移动时,触发on-drag拖拽事件:
根据运动方向的不一样,能够细分为如下几种事件:
能够在任意元素上使用这些指令挂接对应的事件监听函数:
示例代码:
<body ng-controller=”ezCtrl”>
<ion-header-bar class=”bar-positive”>
<h1 class=”title”>on-drag</h1>
</ion-header-bar>
<div class=”scroll-content has-header padding”>
<img src=”img/baymax.png” on-touch=”onTouch($event)” on-drag=”onDrag($event);”>
</div>
</body>
js:
angular.module(“ezApp”,[“ionic”])
.controller(“ezCtrl”,function($scope) {
var ox,oy;
$scope.onTouch = function($event){
ox = $event.target.offsetLeft;
oy = $event.target.offsetTop;
};
$scope.onDrag = function($event){
var el = $event.target,
dx = $event.gesture.deltaX,
dy = $event.gesture.deltaY;
el.style.left = ox + dx + “px”;
el.style.top = oy + dy + “px”;
};
});
在屏幕上按住并快速拖动时,将触发on-swipe划动事件:
根据划动方向的不一样,可细分为如下指令:
能够在任何元素上使用这些指令挂接事件监听函数:
示例代码:
<body ng-controller=”ezCtrl”>
<div class=”scroll-content padding”
on-swipe-up=”onSwipeUp()”
on-swipe-down=”onSwipeDown()”
on-swipe-left=”onSwipeLeft()”
on-swipe-right=”onSwipeRight()”>
<p class=”padding”>按住鼠标快速划!</p>
<i class=”icon {{icon}}”></i>
</div>
</body>
js:
angular.module(“ezApp”,[“ionic”])
.controller(“ezCtrl”,function($scope){
$scope.icon=”ion-arrow-expand”;
$scope.onSwipeUp = function(){
$scope.icon=”ion-arrow-up-a”;
};
$scope.onSwipeDown = function(){
$scope.icon=”ion-arrow-down-a”;
};
$scope.onSwipeLeft = function(){
$scope.icon=”ion-arrow-left-a”;
};
$scope.onSwipeRight = function(){
$scope.icon=”ion-arrow-right-a”;
};
});
除了使用以前介绍的特定指令实现手势事件的监听,也可使用$ionicGesture服务 注册/解除手势事件监听:
参数eventType是支持的事件类型,参看下面介绍;参数callback指定监听函数; 参数$element是要绑定事件的jqLite元素。
on()方法返回的是一个ionic.gesture对象,可供解除监听用。
参数gesture是on()方法返回的结果对象,参数callback是要移除的监听函数。
$ionicGesture服务支持的事件类型有:
hold, tap, doubletap, drag, dragstart, dragend, dragup, dragdown, dragleft, dragright, swipe, swipeup, swipedown, swipeleft, swiperight, transform, transformstart, transformend, rotate, pinch, pinchin, pinchout, touch, release
示例代码:
<body ng-controller=”ezCtrl”>
<ion-header-bar class=”bar-positive”>
<h1 class=”title”>$ionicGesture</h1>
</ion-header-bar>
<ion-content class=”padding”>
<button class=”button” id=”test”>test</button>
</ion-content>
</body>
js:
angular.module(“ezApp”,[“ionic”])
.controller(“ezCtrl”,function($scope,$ionicGesture,$ionicPopup) {
var el = document.querySelector(“#test”);
$ionicGesture.on(“tap”,function(){
$ionicPopup.alert({
title : “提醒”,
template : “这个监听是用$ionicGesture服务注册的!”
})
},angular.element(el));
});
