Vollständiges Beispiel für die Verbindung von Javascript mit Access-Datenbank_Javascript-Kenntnissen

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();
