Ionic Cordova Sqlite 实现保存用户名登陆

1.添加sqlite 组件

cordova plugin add https://github.com/litehelpers/Cordova-sqlite-storage.git --save

2.编写代码 app.js  =>run=> $ionicPlatform.ready 添加

if(window.cordova ) {
      ltdb = $cordovaSQLite.openDB({name: "ltapp.db", location: 1});
      //创建用户表
      $cordovaSQLite.execute(ltdb, "CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT, email TEXT, phonenumber INTEGER, password TEXT)");

      $cordovaSQLite.execute(ltdb, 'SELECT COUNT(*) FROM users ').then(function (res) {
          if (res.rows.length < 0) {
            var query = "INSERT INTO users (name,email,phonenumber,password) VALUES ( ?, ?, ?, ?)";
            $cordovaSQLite.execute(ltdb, query, ['admin', 'sulin11026@163.com', '13683365354', '123']).then(function (result) {
              console.log("success");
            }, function (error) {
            })
          }
        },
        function (error) {
          console.log(error);
        }
      );
    }

controllers .js

controller('LoginCtrl',['$scope', '$state', '$ionicPopup', 'AuthService', function($scope, $state, $ionicPopup, AuthService) {
 $scope.login = function() {
    var user= $scope.user;
    AuthService.login(user.uname, user.pwd).then(function(authenticated) {

     $state.go('tabs.home', {}, {reload: true});
     $scope.setCurrentUsername(user.username);
   }, function(err) {
     var alertPopup = $ionicPopup.alert({
       title: '登录失败',
       template: '请输入正确的账号密码!'
     });
   });
  };
}])

servcies.js

.factory('AuthService',['$q', '$http','$cordovaSQLite', function($q, $http,$cordovaSQLite) {var username = '';var login = function(name, pw) {
    return $q(function(resolve, reject) {
      try {
        $cordovaSQLite.execute(ltdb, "SELECT * FROM users WHERE name = ? ",[name]).then(
          function(res) {
            if (res.rows.length > 0) {
              if(pw.toLocaleUpperCase()==res.rows.item(0).password.toLocaleUpperCase()){
                resolve('Login success.');
              }
            }else{
              reject('Login Failed.');
            }
          },
          function(error) {
            reject('Login Failed.');
          }
        );
      }
      catch(ex){
      }
    });
  };return {
    login: login
  };
}])

index.html

<ion-view class="login" hide-nav-bar="true" style="z-index: 1" cache-view="false">
  <form ng-submit="login()"   name="theform">
    <div id="login">
      <div class="logo"><img src="img/fixed/logo.png"></div>
      <div class="fill">
        <label class="item item-input ion-ios-person-outline">
        <input type="text" placeholder="账号" ng-model="user.uname"
               ng-focus="hide='1'" ng-blur="hide='1'" ng-required="true" >
      </label>
        <label class="item item-input ion-ios-locked-outline">
          <input type="password" placeholder="密码" ng-model="user.pwd" ng-required="true"
                 ng-focus="hide='1'" ng-blur="hide='1'" >
         </label>
        <label class="btn">
          <button class="button button-block button-light" type="submit">登录</button>
        </label>
    </div>
