cordova – Security_ERR：DOM异常18 openDatabase()使用Phonegap

我使用phonegap模板创建了 HTML5 / JQuery项目.我试图在本地数据库上存储信息.目前,我正在使用模拟器ElectricMobileStudio2012进行测试.
我在这行代码中收到错误“Security_ERR：DOM Exception 18”：

var db = window.openDatabase("MobileInspection","1.0","Mobile Inspection Database",200000);

这是我的代码.我已经坚持了几天,我甚至尝试使用这些代码来解决错误：

navigator.openDatabase = window.openDatabase = DroidDB_openDatabase;

window.droiddb = new DroidDB();

这是我的代码：

function SaveUserInfoLocally(data) {
    try {
        var rememberMe = $('#chkRememberMe').is(':checked')
        if (rememberMe) {
            // TODO: Save user details in local db.
            //navigator.openDatabase = window.openDatabase = DroidDB_openDatabase;
            //window.droiddb = new DroidDB();
            var db = window.openDatabase("MobileInspection",200000);
            db.transaction(populateUsersTable,errorCB,successCB);
            db.transaction(queryDB,errorCB);
        }
    }
    catch (error) {
        alert(error);
    }
}

function populateUsersTable(tx) {
    try {
        var userName = window.localStorage.getItem("UserName");
        var firstName = window.localStorage.getItem("FirstName");
        var lastName = window.localStorage.getItem("LastName");
        //alert(userName + " " + firstName + " " + lastName);
        tx.executesql("DROP TABLE IF EXISTS UserDetails");
        tx.executesql("CREATE TABLE IF NOT EXISTS UserDetails (UserName,FirstName,LastName)");
        tx.executesql("INSERT INTO UserDetails (UserName,LastName) VALUES ('" + userName + "','" + firstName + "','" + lastName + "')");
        alert("populate");
    }
    catch (exception) {
        alert(exception);
    }
}

function errorCB(err) {
    alert("Error processing: " + err);
}

function successCB() {
    alert("success!"); 
}

function queryDB(tx) {
    try {
        tx.executesql('SELECT * FROM UserDetails',[],querySuccess,errorCB);
    }
    catch (exception) {
        alert(exception);
    }
}

// Testing
function querySuccess(tx,results) {
    try {
        if (results) {
            alert("records");
        }
        else {
            alert(results);
        }
    }
    catch (exception) {
        alert(exception);
    }
}

解决方法

我有一个类似的问题 – 因此我在这个问题上遇到了麻烦.

确保在deviceready块中执行所有localstorage调用：

document.addEventListener("deviceready",onDeviceReady,false);

function onDeviceReady() {
    //do ALL your localstorage stuff here
}
