在PhoneGap應用程序中，咱們能夠利用一款名叫Cordova-SQLitePlugin的插件來方便的操做基於瀏覽器內置數據庫或獨立的SQLite數據庫文件，此插件的基本信息：javascript

1.項目地址：https://github.com/brodysoft/Cordova-SQLitePlugincss

2.項目討論組：https://groups.google.com/forum/#!forum/Cordova-SQLitePluginhtml

3.有用的參考文章：http://yeti.mtm.net.cn/?p=1437java

如下是我利用Cordova3.5.0建立的Android工程利用此插件的過程：android

1.建立工程testDb：git

cordova create testSQLite com.me.testSQLite testDb

2.添加Android工程：github

cd testSQLite
cordova platform add android

3.編譯此工程：sql

cordova build

4.配置Cordova-SQLitePlugin插件：數據庫

從https://github.com/brodysoft/Cordova-SQLitePlugin下載下來的壓縮包中有如下內容：express

www/SQLitePlugin.js：此文件要在.HTML中用到。

src/android/org/pgsqlite/SQLitePlugin.java：此文件由PhoneGap引用。

在咱們的Android工程中的配置文件「platforms/android/res/xml/config.xml」中加入此插件的配置項：

<feature name="SQLitePlugin">
<param name="android-package" value="org.pgsqlite.SQLitePlugin" />
</feature>

而後把www/SQLitePlugin.js拷貝到Android工程中的www文件夾中，而且把src/android/org/pgsqlite/SQLitePlugin.java拷貝到Android工程中的

"plugins/org/pgsqlite.SQLitePlugin.java"。不出意外的話，插件就配置好了。

5.修改Android工程中www目錄下的index.html文件，用於測試看插件是否正常工做了，個人測試代碼以下：

  db.transaction(function(tx) {

    tx.executeSql('CREATE TABLE IF NOT EXISTS test_table (id integer primary key, data text, data_num integer)');
	console.log( "正在執行數據庫操做!" );
    // demonstrate PRAGMA:

      console.log("PRAGMA res: " + JSON.stringify(res));
    });

    tx.executeSql("INSERT INTO test_table (data, data_num) VALUES (?,?)", ["test", 100], function(tx, res) {
      console.log("insertId: " + res.insertId + " -- probably 1");
      console.log("rowsAffected: " + res.rowsAffected + " -- should be 1");

      db.transaction(function(tx) {
        tx.executeSql("select count(id) as cnt from test_table;", [], function(tx, res) {
          console.log("res.rows.length: " + res.rows.length + " -- should be 1");
          console.log("res.rows.item(0).cnt: " + res.rows.item(0).cnt + " -- should be 1");
        });
      });

    }, function(e) {
      console.log("ERROR: " + e.message);
    });
  });
  
  console.log( "結束操做數據庫!" );
}

6.而後再次編譯一下：
