ionic js 模型 $ionicModal 可以遮住用户主界面的内容框

 ionic 模型

$ionicModal

$ionicModal 可以遮住用户主界面的内容框。

你可以在你的 index 文件或者是其他文件内嵌入以下代码(里面的代码可以根据你自己的业务场景相应的改变)。

<script id="my-modal.html" type="text/ng-template">
<ion-modal-view>
<ion-header-bar>
<h1 class="title">My Modal title</h1>
</ion-header-bar>
<ion-content>
Hello!
</ion-content>
</ion-modal-view>
</script>

然后你就可以在你的 Controller 里面的注入 $ionicModal 。然后调用你刚刚写入的模板，进行初始化操作。就像下面的代码：

angular.module('testApp', ['ionic'])
.controller('MyController', function($scope, $ionicModal) {
$ionicModal.fromTemplateUrl('my-modal.html', {
scope: $scope,
animation: 'slide-in-up'
}).then(function(modal) {
$scope.modal = modal;
});
$scope.openModal = function() {
$scope.modal.show();
};
$scope.closeModal = function() {
$scope.modal.hide();
};
//Cleanup the modal when we're done with it!
$scope.$on('$destroy', function() {
$scope.modal.remove();
});
// Execute action on hide modal
$scope.$on('modal.hidden', function() {
// Execute action
});
// Execute action on remove modal
$scope.$on('modal.removed', function() {
// Execute action
});
});

方法

fromTemplate(templateString, options)

返回: 对象, 一个ionicModal控制器的实例。

fromTemplateUrl(templateUrl, options)

返回： promise对象。Promises对象是CommonJS工作组提出的一种规范，目的是为异步编程提供统一接口。

ionicModal

由$ionicModal服务实例化。

提示：当你完成每个模块清除时，确保调用remove()方法，以避免内存泄漏。

注意：一个模块从它的初始范围广播出 'modal.shown' 和 'modal.hidden' ，把自身作为一个参数来传递。

方法

initialize(可选)

创建一个新的模型控制器示例。

show()

显示模型实例

返回值: promise promise对象,在模型完成动画后得到解析

hide()

隐藏模型。

返回值: promise promise对象,在模型完成动画后得到解析

remove()

从 DOM 中移除模型实例并清理。

返回值: promise promise对象,在模型完成动画后得到解析

isShown()

返回：布尔值，用于判断模型是否显示。
