Question

我正在创建一个phoneagap移动应用程序，并希望使用WebSql将数据存储在本地存储中。

所以我跟着这个......

Create Android App with SQLite using Phonegap + Jquery mobile

我已经成功创建了表，但是当我在按钮上单击时调用executeSql（）方法时，它会给出错误（23）未授权。

我正在使用phonegap 3.5.0-0.20.4版本。这是最新的，在Android 4.2.2上运行，我怎样才能解决这个问题，究竟是什么问题是???

这是我的代码： -

首先，我已经注册了一个deviceReady侦听器并使用

创建了一个数据库

document.addEventListener("deviceready", onDeviceReady, false);
var db = window.openDatabase("abc_db", "1.0", "The ABC", 200000);

然后

     function onDeviceReady(){
            db.transaction(populateDB, errorCB, successCB);
     }

        //create table and insert some record
        function populateDB(tx) {
            tx.executeSql('CREATE TABLE IF NOT EXISTS Authentication (company_name TEXT NOT NULL, company_engineer TEXT NOT NULL, company_project TEXT NOT NULL, password TEXT NOT NULL)');
            tx.executeSql('INSERT INTO Authentication(company_name, company_engineer, company_project, password) VALUES ("Company 1", "Engineer 1", "Project 1", "1111")');
            tx.executeSql('INSERT INTO Authentication(company_name, company_engineer, company_project, password) VALUES ("Company 2", "Engineer 2", "Project 2", "2222")');
            tx.executeSql('INSERT INTO Authentication(company_name, company_engineer, company_project, password) VALUES ("Company 3", "Engineer 3", "Project 3", "3333")');
        }

        //function will be called when an error occurred
        function errorCB(err) {
            alert("Error processing SQL: "+err.code);
        }

        //function will be called when process succeed
        function successCB() {
            alert("success!");                
        }

然后点击我正在使用的按钮...

funcion doLogin(){
          password = document.forms["login"]["passowrd"].value;
          company_name = document.forms["login"]["company"].value;
          company_engineer = document.forms["login"]["company_engineer"].value;
          company_project = document.forms["login"]["company_project"].value;

          db = window.openDatabase("abc_db", "1.0", "The ABC", 200000);
          db.transaction(queryDB,errorCB);
      }

function queryDB(tx){
               var qry = "SELECT * FROM Authentication WHERE company_name = '" + company_name + "' AND company_engineer = '" + company_engineer + "' AND company_project = '" + company_project + "' AND `password` = '" + password + "'";

               tx.executeSql(qry ,[],querySuccess, errorGet);
           }

 function querySuccess(tx, result){
                if(result.rows.length !== 0){
                    document.location.href = 'home.html';
                } else {
                    alert('Invalid Username or password');
                }

           }

错误（23）未在websql中授权
