实例如下：
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Database Example</title> <script type="text/javascript" charset="UTF-8" src="cordova.js"></script> <script type="text/javascript" charset="UTF-8"> document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() { var db=window.openDatabase("Test","1.0","Test",200000); db.transaction(populateDB,errorDB,successDB); } //初始化数据库数据 function populateDB(tx){ tx.executeSql(DROP TABLE IF EXISTS test1); tx.executeSql(CREATE TABLE IF NOT EXISTS test1 (id unique,name)); tx.executeSql(INSERT INTO test1(id,name) VALUES(1,"Tony")); tx.executeSql(INSERT INTO test1(id,name) VALUES(2,"Bill")); tx.executeSql(INSERT INTO test1(id,name) VALUES(3,"Tony")); } //查询方法 function queryDB(tx){ tx.executeSql(SELECT * FROM test1,[],querySuccess,errorDB); } //查询成功回调 function querySuccess(tx,results){ var len=results.rows.length; var status=document.getElementById("status"); var string ="Rows:"+len+"<br />"; for(var i=0;i<len;i++){ string+=results.rows.item(i).name+"<br />"; } status.innerHTML=string; } //执行初始化数据成功后的回调 function successDB(){ var db=window.openDatabase("Test","1.0","Test",200000); db.transaction(queryDB,errorDB); } //失败回调 function errorDB(err){ alert(Error processing SQL:+err.code); } </script> </head> <body> <h1>Names</h1> <div id=status></div> </body> </html>以上这篇使用phonegap操作数据库的实现方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。
