保存到localstorage切換和刪除localstorage如果它的假

我正在使用離子和angularjs的應用程序，這是我想實現的，當切換開關是它應該設置localstorage爲true，當它已關閉，應刪除本地存儲。保存到localstorage切換和刪除localstorage如果它的假

.controller('shops',['$scope','$http','$timeout',function($scope,$http,$timeout) { 
    $http.get('http://localhost/work/templates/source.php').success(function(data){ 
     $scope.shops=data; 
    }); 

    $scope.pushNotificationChange = function(item) { 
     $timeout(function() { 
      if ($scope.pushNotification = { checked: true }) { 
       alert("false"); 
      } 
      //alert('Push Notification Change: '+ $scope.pushNotification.checked); 

      localStorage.setItem("shop_id",($scope.item.shop_id)); 
     }, 0); 
    }; 
}]);

HTML

<div align="right"> 
    <label class="toggle toggle-balanced"> 
     <input type="checkbox" 
       ng-model="pushNotification.checked" 
       ng-change="pushNotificationChange()"> 
     <div class="track"> 
      <div class="handle"></div> 
     </div> 
    </label> 
</div>

，什麼是錯誤？你期望的行爲是什麼？ – CozyAzure

爲什麼使用'if（$ scope.pushNotification = {checked：true}）'而不是'if（$ scope.pushNotification.checked）'？ – Lex

<html ng-app="ionicApp"> 
    <head> 
    <meta charset="utf-8"> 
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width"> 

    <title>Toggles</title> 

    <link href="//code.ionicframework.com/nightly/css/ionic.css" rel="stylesheet"> 
    <script src="//code.ionicframework.com/nightly/js/ionic.bundle.js"></script> 
    </head> 

    <body ng-controller="MainCtrl"> 

    <ion-header-bar class="bar-positive"> 
     <h1 class="title">Toggles</h1> 
    </ion-header-bar> 
    <ion-content> 
     <ion-toggle ng-model="pushNotification.checked" 
        ng-checked="pushNotification.checked"> 
      {{ pushNotification.text }} 
     </ion-toggle> 
     <div class=""> 
      {{pushNotification.checked}} 
     </div> 
    </ion-content> 
    </body> 
</html>

你的js代碼將

angular.module('ionicApp', ['ionic']) 

.controller('MainCtrl', function($scope) { 

    $scope.pushNotification = {}; 
    $scope.pushNotification.text = "Sample" 
    $scope.pushNotification.checked = false; 

    $scope.pushNotificationChange = function() { 
    console.log('Push Notification Change', $scope.pushNotification.checked); 
     if($scope.pushNotification.checked){ 
      //set your local storage 
     }else{ 
      //remove from local storage. 
     } 
    }; 

});

爲什麼使用'if（$ scope.pushNotification.checked =='true'）'？爲什麼不'if（$ scope.pushNotification.checked）'？ – Lex

是的，那可以。 – Naveen

我得到這個錯誤：TypeError：無法讀取屬性'檢查'未定義 – user6579134

一個好主意，可以創建自己的指令...
