我有一个使用Ionic Framework的AngularJS应用程序,它有一个带有“设置”选项卡的选项卡视图,该选项卡将存储用户选项。我想在应用程序最初启动时使用这些设置,而我可以在localStorage中使用存储的值,我希望能够检查设置选项卡上设置的选项。
现在,如果你加载设置选项卡,你会看到其中一个单选按钮在你加载时从关闭到开启,这就是每当我设置一个默认值时会发生什么。如何在应用程序启动时设置此设置,而不是在打开选项卡本身时设置?
这就是我的controllers.js的样子:
angular.module('starter.controllers', [])
.controller('DashCtrl', function($scope, $window, $ionicPlatform) {
$ionicPlatform.ready(function() {
if ( ! $window.localStorage.getItem( 'grossoption' ) ) {
$window.localStorage.setItem( 'grossoption', 'year' );
}
if ( ! $window.localStorage.getItem( 'resultoption' ) ) {
$window.localStorage.setItem( 'resultoption', 'month' );
}
});
$scope.grossOptionsList = [
{ text: "Year", value: "year" },
{ text: "Month", value: "month" },
{ text: "Week", value: "week" },
{ text: "Day", value: "day" }
];
$scope.resultsOptionsList = [
{ text: "Year", value: "year" },
{ text: "Month", value: "month" },
{ text: "Week", value: "week" },
{ text: "Day", value: "day" }
];
// Default values
$scope.data = {};
$scope.data.grossOptions = 'year';
$scope.data.resultOptions = 'month';
$scope.updateGrossOptions = function(item) {
$window.localStorage.setItem( 'grossoption', item.value );
console.log( 'Gross option: ' + item.value );
}
$scope.updateResultOptions = function(item) {
$window.localStorage.setItem( 'resultoption', item.value );
console.log( 'Results option: ' + item.value );
}
})
.controller('SettingsCtrl', function($scope, $window, $ionicPlatform) {
$ionicPlatform.ready(function() {
if ( ! $window.localStorage.getItem( 'toggle1' ) ) {
$window.localStorage.setItem( 'toggle1', 'true' );
}
if ( ! $window.localStorage.getItem( 'toggle2' ) ) {
$window.localStorage.setItem( 'toggle2', 'false' );
}
});
$scope.data = {};
$scope.data.toggle1 = $window.localStorage.getItem( 'toggle1' ) === "true";
$scope.data.toggle2 = $window.localStorage.getItem( 'toggle2' ) === "true";
$scope.update_toggle1 = function() {
$window.localStorage.setItem( 'toggle1', $scope.data.toggle1 );
console.log( 'Toggle 1: ' + $scope.data.toggle1 );
}
$scope.update_toggle2 = function() {
$window.localStorage.setItem( 'toggle2', $scope.data.toggle2 );
console.log( 'Toggle 2: ' + $scope.data.toggle2 );
}
}) 我已设置an example plnkr here,其中显示了我的应用在加载“设置”标签时当前所具有的行为。
感谢有关如何以最佳方式处理Angular的任何反馈。

您可以在“ng-checked”中使用“if”条件,如下所示:
<ion-toggle ng-checked="(myVar== 1)?true:false;" ng-change="myFunc(myVar)" ng-model="myVar" toggle-class="toggle-calm">{{myVar}}</ion-toggle>
