尝试将数据插入 sqlite 数据库,数据是静态的,我正在通过函数传递它,但 ng click 不起作用。因为我是新手,所以请详细回答...提前致谢。

 //this is my module
var db=null;
var myApp=angular.module('starter', ['ionic','ngCordova'])

.run(function($ionicPlatform,$cordovaSQLite) {
$ionicPlatform.ready(function() {
if(window.cordova && window.cordova.plugins.Keyboard) {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);

// Don't remove this line unless you know what you are doing. It stops the viewport
// from snapping when text inputs are focused. Ionic handles this internally for
// a much nicer keyboard experience.
cordova.plugins.Keyboard.disableScroll(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
db = $cordovaSQLite.openDB({name:"my.db",location:'default'});
$cordovaSQLite.execute(db,"CREATE TABLE IF NOT EXISTS user(id integer primary key, username text, password text)")
});
})


//this is my controller

myApp.controller('SignInCtrl',['$cordovaSQLite', function($scope, $cordovaSQLite) {
$scope.insert=function(username,password){
alert("hii");
var query="INSERT INTO user(username,password) VALUES(?,?)";
$cordovaSQLite.execute(db.query,[username,password]).then(function(res){
console.log("Insert ID ->" + res.insertId);
},
function(err){
console.error(err);
});
}
$scope.select = function(username) {
var query = "SELECT username, password FROM user WHERE username = ?";
$cordovaSQLite.execute(db, query, [password]).then(function(res) {
if(res.rows.length > 0) {
console.log("SELECTED -> " + res.rows.item(0).username + " " + res.rows.item(0).password);
} else {
console.log("No results found");
}
}, function (err) {
console.error(err);
});
}
}])

//this is my page

<ion view view-title="Sign-In" name="Login-View">
<ion content class="padding">
<div class="list list-inset">
<label class="item item-input">
<input type="text" placeholder="Username" ng-model="data.username">
</label>
<label class="item item-input">
<input type="password" placeholder="Password" ng-model="data.password"></input>
</label>
</div>
</ion>
<button class="button button-block button-positive" ng-click="login(data)">Login</button>
</ion>
<br>
<a href="#/Signup" class="button button-block button-stable">Sign Up</a>
<a href="#/ForgotPassword" class="button button-block button-stable">Forgot Password</a>
<a href="#/orderpage" class="button button-block button-stable">Order page</a>

<button class="button button-block button-positive" ng-click="insert('ran','badu')">insert</button>
<button class="button button-block button-positive" ng-click="select('ran')">select</button>

//this is my index page

<body ng-app="starter">
<ion-header-bar class="bar-positive">
<h1 class="title">Billing system</h1>
<button class="button icon ion-navicon"></button>
<button class="button icon ion-search"></button>
</ion-header-bar>
<!-- <ion-content > -->
<!-- <P>I am in index</P>
<a href="#/Login">Loginpage</a> -->

<!-- </ion-content> -->

<ion-nav-view class="slide-left-right"></ion-nav-view>
</body>


//this is my route

.config(function($stateProvider,$urlRouterProvider) {
$stateProvider
.state('Login',{
url:'/Login',
templateUrl:'templates/Login.html',
controller:'SignInCtrl'

})
.state('Signup',{
url:'/Signup',
templateUrl:'templates/Signup.html',
controller:'SignInCtrl'
})
.state('ForgotPassword',{
url:'/ForgotPassword',
templateUrl:'templates/ForgotPassword.html',
controller:'SignInCtrl'
})

.state('orderpage',{
url:'/orderpage',
templateUrl:'templates/orderpage.html',
controller:'SignInCtrl'
})
$urlRouterProvider.otherwise('/Login');

})

最佳答案

SignInCtrl 声明有误。更改这行代码

myApp.controller('SignInCtrl',['$cordovaSQLite', function($scope, $cordovaSQLite)

myApp.controller('SignInCtrl',['$scope','$cordovaSQLite', function($scope, $cordovaSQLite)

这里的问题是你使用了内联依赖注入(inject)而且顺序很重要
