@ravi，

嘿，PhoneGap 正在开发 WebView，这是在 HTML5 上创建的。你知道html没有直接支持sqlite。因此，在 phonegap 内置功能中。

在 Phonegap 在应用程序目录上创建第一次数据库并始终由 Syntex 使用此数据库。欲了解更多信息，请阅读此内容。

您可以创建一个新项目并在 index.html 中仅复制此 Syntex。

<!DOCTYPE html>
<html>
  <head>
    <title>Contact Example</title>

    <script type="text/javascript" charset="utf-8" src="phonegap-1.2.0.js"></script>
    <script type="text/javascript" charset="utf-8">

    // Wait for PhoneGap to load
    //
    document.addEventListener("deviceready", onDeviceReady, false);

    // 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")');
    }

    // Query the database
    //
    function queryDB(tx) {
        tx.executeSql('SELECT * FROM DEMO', [], querySuccess, errorCB);
    }

    // Query the success callback
    //
    function querySuccess(tx, results) {
        var len = results.rows.length;
        console.log("DEMO table: " + len + " rows found.");
        for (var i=0; i<len; i++){
            console.log("Row = " + i + " ID = " + results.rows.item(i).id + " Data =  " + results.rows.item(i).data);
        }
    }

    // Transaction error callback
    //
    function errorCB(err) {
        console.log("Error processing SQL: "+err.code);
    }

    // Transaction success callback
    //
    function successCB() {
        var db = window.openDatabase("Database", "1.0", "PhoneGap Demo", 200000);
        db.transaction(queryDB, errorCB);
    }

    // PhoneGap is ready
    //
    function onDeviceReady() {
        var db = window.openDatabase("Database", "1.0", "PhoneGap Demo", 200000);
        db.transaction(populateDB, errorCB, successCB);
    }

    </script>
  </head>
  <body>
    <h1>Example</h1>
    <p>Database</p>
  </body>
</html>
