js 连接数据库

1，首先创建ODBC数据源。

2，确保IE的的安全设置“通过域访问数据源”启用。

<script language="javascript">
    //用 javascript 写服务器端连接数据库的代码示例
    var conn = new ActiveXObject("ADODB.Connection");
    conn.Open("Provider=SQLOLEDB.1; Data Source=.; User ID=sa; " + "Password=qaz123$%^; Initial Catalog=Vancl_Union"); 
    var rs = new ActiveXObject("ADODB.Recordset");
    var sql = "select  * from dbo.Channel";
    rs.open(sql, conn);
    alert(rs(0)); //取出第一个来
    var id = "";
    var name="";
    while (!rs.EOF) {
        // id+= rs.Fields("id");
        name += rs.Fields("name");
        rs.MoveNext;
    } 
   // document.writeln(id);
    document.writeln(name);
    rs.close();
    rs = null;
    conn.close();
    conn = null;
   
     </script>

function Insert()

{

  var con = new ActiveXObject("ADODB.Connection");
        //连接字符串
        //var str = "DRIVER={SQL SERVER};SERVER=.;uid=sa;pwd=qaz123$%^;database=Test";
        var str = "Provider=SQLOLEDB.1; Data Source=.; User ID=sa; " + "Password=qaz123$%^; Initial Catalog=Test";
        //打开数据源
        con.Open(str);
        var sql = "insert into Test(Name,Email) values('11','11')";
 
        //        //执行sql语句
        con.Execute(sql);

}
