ionic background layer
We often need to show or hide the background layer on the UI, such as in pop-up boxes, loading boxes, and other pop-up layers.
In the component, you can use $ionicBackdrop.retain() to display the background layer, and use $ionicBackdrop.release() to hide the background layer.
Every time retain is called, the background will remain displayed until release is called to eliminate the background layer.
Example
HTML code
<body ng-app="starter" ng-controller="actionsheetCtl" > <ion-pane> <ion-content > <h2 ng-click="action()">$ionicBackdrop</h2> </ion-content> </ion-pane> </body>
JavaScript code
angular.module('starter', ['ionic'])
.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if(window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});
})
.controller( 'actionsheetCtl',['$scope','$timeout' ,'$ionicBackdrop',function($scope,$timeout,$ionicBackdrop){
$scope.action = function() {
$ionicBackdrop.retain();
$timeout(function() { //默认让它1秒后消失
$ionicBackdrop.release();
}, 1000);
};
}])
