我是android PhoneGap的新手。
<script type="text/javascript" charset="utf-8" src="js/cordova.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
var db = window.openDatabase("raddyx", "1.0", "Cordova Demo", 200000);
db.transaction(populateDB, errorCB, successCB);
}
function populateDB(tx) {
tx.executeSql('DROP TABLE IF EXISTS DEMO');
tx.executeSql('CREATE TABLE IF NOT EXISTS DEMO (id unique, data)');
tx.executeSql('INSERT INTO DEMO (id, data) VALUES (1, "First row")');
}
function errorCB(tx, err) {
alert("Error processing SQL: "+err);
}
function successCB() {
alert("success!");
}
</script>
我正在使用上面的示例代码。我的数据库名称raddyx
。我无法创建数据库。你能告诉我如何在PhoneGap中创建raddyx
数据库吗?
编辑 - 当我在我的手机中运行时,它显示Unfortunately, APP_NAME_HERE has stopped.
如果我删除了我的连接代码,它可以正常工作。

您可以使用以下函数创建数据库:
function queryDB() {
var db = window.openDatabase("Database", "1.0", "Cordova login", 300000);
db.transaction(inputDb, errorCB);
}
之后,调用函数inputDb,如下所示:
function inputeDb(db2) {
db2.executeSql('DROP TABLE IF EXISTS login');
db2.executeSql('CREATE TABLE IF NOT EXISTS login (id_Login INTEGER PRIMARY KEY AUTOINCREMENT, UserName VARCHAR(150) NULL, UserPassword VARCHAR(100) NULL, UserHash VARCHAR(50) NULL)');
db2.executeSql('INSERT INTO login (UserName, UserPassword) VALUES ("'+uname1+'", "'+upass1+'")');
db2.executeSql('DROP TABLE IF EXISTS MDataT');
db2.executeSql('CREATE TABLE IF NOT EXISTS MDataT (id_MData INTEGER PRIMARY KEY, MData INTEGER)');
db2.executeSql('INSERT INTO MDataT (id_MData, MData) VALUES ("1", "'+MData+'")');
//alert("Username and Password - Set in DB");
location.href="serverLogin.html";
}
