Question

我是离子1开发的新手。我试图显示我插入到我的SQLite表中的数据。我希望在Chrome控制台中看到它们。但是，我收到以下错误：

ionic.bundle.js:26799 TypeError: Cannot read property 'transaction' of null
    at Object.execute (ng-cordova.min.js:9)
    at ChildScope.$scope.insert (controllers.js:22)
    at fn (eval at compile (ionic.bundle.js:27643), <anonymous>:4:209)
    at ionic.bundle.js:65429
    at ChildScope.$eval (ionic.bundle.js:30400)
    at ChildScope.$apply (ionic.bundle.js:30500)
    at HTMLButtonElement.<anonymous> (ionic.bundle.js:65428)
    at defaultHandlerWrapper (ionic.bundle.js:16792)
    at HTMLButtonElement.eventHandler (ionic.bundle.js:16780)
    at triggerMouseEvent (ionic.bundle.js:2953)

这是我的控制器代码的片段。我有一个单独的控制器js文件。

.controller('salesCtrl', ['$scope', '$stateParams','$cordovaSQLite', '$ionicPlatform',
    function ($scope, $stateParams,$cordovaSQLite, $ionicPlatform) {

        $ionicPlatform.ready(function () {

            var db = null;

            if (window.cordova) {
                db = $cordovaSQLite.openDB({ name: "pos.db" }); //device
                console.log("not in browser");
            } else{
                db = window.openDatabase("pos.db", '1', 'my', 1024 * 1024 * 100); // browser
                console.log("browser");
            }
            $cordovaSQLite.execute(db,"CREATE TABLE IF NOT EXISTS items(id integer primary key AUTOINCREMENT,firstname text  NOT NULL,lastname text  NOT NULL)");
        });

        $scope.insert = function(){
            var query="INSERT into items(firstname,lastname) VALUES(?,?)";
            $cordovaSQLite.execute(db,query,["name1","name2"]).then(function(result){
                console.log(result.rows);
            },function(error){
                console.log(error);

            }); 

        }


}])

这些是我安装的cordova插件：

cordova-plugin-console 1.0.6 "Console"
cordova-plugin-device 1.1.5 "Device"
cordova-plugin-splashscreen 4.0.2 "Splashscreen"
cordova-plugin-statusbar 2.2.2 "StatusBar"
cordova-plugin-whitelist 1.3.2 "Whitelist"
cordova-sqlite-storage 1.5.3 "Cordova sqlite storage plugin"
ionic-plugin-keyboard 2.2.1 "Keyboard"

无法读取null ionic 1的属性'transaction'
