我正在使用PhoneGap,n在xCode中使用此代码然后正常运行并在iphone模拟器中显示数据库--> 5.0-->应用程序-->(应用程序名称)-> Webkit->数据库
但是当我在 Eclipse 中时,它不会在 ddms->data->data->database 中创建任何数据库。它如何正常工作。建议我
<!DOCTYPE html>

<script type="text/javascript" charset="utf-8" src="phonegap.js"></script>
<script type="text/javascript" charset="utf-8">
// Wait for PhoneGap to load
//
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap is ready
//
function onDeviceReady() {
var db = window.openDatabase("Database", "1.0", "PhoneGap Demo", 200000);
db.transaction(populateDB, errorCB, successCB);
}
// Populate the database
//
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")');
tx.executeSql('INSERT INTO DEMO (id, data) VALUES (2, "Second row")');
}
// Transaction error callback
//
function errorCB(tx, err) {
alert("Error processing SQL: "+err);
}
// Transaction success callback
//
function successCB() {
alert("success!");
}
