Javascript连接Access数据库完整实例

本文实例讲述了Javascript连接Access数据库的方法。分享给大家供大家参考。具体实现方法如下：

var roc = roc || {};
roc.db = roc.db ||{};
//创建一个连接
roc.db.createDb = function(){
 var conn = new ActiveXObject("ADODB.Connection"),
   fso = new ActiveXObject("Scripting.FileSystemObject"),
   connstr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fso.GetFile("./db/Sigma.mdb");
 conn.Open(connstr);//打开数据库
 roc.db.conn = conn;
 return roc.db.conn;
};
//获取连接
roc.db.getDb = function(){
 if( roc.db.conn ){
   return roc.db.conn;
 }else{
   return roc.db.createDb();
 }
};
//关闭连接
roc.db.closeConn = function(){
 if( roc.db.conn ){
   roc.db.conn.close();
   roc.db.conn = null;
 }
};
//获取结果集
roc.db.getRs = function( sqlStr ){
 var mysql = roc.dom.trim( sqlStr );
 if(mysql == ''){return;}
 var rs = new ActiveXObject("ADODB.Recordset"),
   myConn = roc.db.getDb();
 rs.open( sqlStr , myConn );
 return rs;
};
//关闭结果集
roc.db.closeRs = function( rs ){
 rs.close();
 rs =null;
};
//更新、插入
roc.db.execute = function( sqlStr ){
 var myConn = roc.db.getDb();
 myConn.execute( sqlStr );
 roc.db.closeConn();
};
