JavaScript使用ActiveXObject访问Access和SQL Server数据库

JS操作 Access 数据库

<SCRIPT LANGUAGE="JavaScript"> 

<!-- 

var filePath = location.href.substring(0, location.href.indexOf("实例197.连接Access数据库.html"));    //以当前页面文件为基础,找到文件所在的绝对路径 

var path = filePath + "197.mdb"; 

path = path.substring(8);           

var objdbConn = new ActiveXObject("ADODB.Connection");        

var strdsn = "driver={Microsoft Access Driver (*.mdb)};dbq=" + path;    

objdbConn.Open(strdsn);                      

document.write("连接ACCESS数据库成功!<br>"); 

objdbConn.Close();                         

//--> 

</SCRIPT> 

连接SQL Server数据库

<SCRIPT LANGUAGE="JavaScript"> 

<!-- 

var objdbConn = new ActiveXObject("ADODB.Connection");   

var strdsn = "Driver={SQL Server};SERVER=(local);UID=sa;PWD=111111;DATABASE=hljdatabase";   

objdbConn.Open(strdsn);      

document.write("数据库连接成功<br>");     

objdbConn.Close();                    

//--> 

</SCRIPT> 

查询数据库实例

<SCRIPT LANGUAGE="JavaScript"> 

<!-- 

var objdbConn = new ActiveXObject("ADODB.Connection");   

var strdsn = "Driver={SQL Server};SERVER=(local);UID=sa;PWD=111111;DATABASE=hljdatabase";      // 需要修改自己的服务器地址,用户名,密码 

objdbConn.Open(strdsn);      

var objrs = objdbConn.Execute("SELECT * FROM 表 where 关联=0");                  // 输入本地的表 

var fdCount = objrs.Fields.Count - 1;          

if (!objrs.EOF){                                

  document.write("<table border=1><tr>");    

  for (var i=0; i <= fdCount; i++)                 

      document.write("<td><b>" + objrs.Fields(i).Name + "</b></td>"); 

  document.write("</tr>"); 

 

  while (!objrs.EOF){                    

    document.write("<tr>");              

    for (i=0; i <= fdCount; i++) 

       document.write("<td valign='top'>" + objrs.Fields(i).Value + "</td>"); 

    document.write("</tr>"); 

    objrs.moveNext();                  

  } 

  document.write("</table>");  

else  

  document.write("数据库内没有记录!<br>"); 

objrs.Close();                          

objdbConn.Close();                    

//--> 

</SCRIPT> 

操作数据库实例

<SCRIPT LANGUAGE="JavaScript"> 

<!-- 

var objdbConn = new ActiveXObject("ADODB.Connection");   

var strdsn = "Driver={SQL Server};SERVER=(local);UID=sa;PWD=111111;DATABASE=hljdatabase";   // 需要修改自己的服务器地址,用户名,密码 

objdbConn.Open(strdsn);      

objdbConn.Execute("update 表 set 关联=0");                    // 请写入自己的执行语句 

document.write("更新数据成功!<br>"); 

objdbConn.Close();                    

//--> 

</SCRIPT>
