ActiveXObject未定义

Question

我的程序是使用javascript在网页中获取员工详细信息。这在IE5,6,8中成功运行。但没有工作Mozilla Firefox。请帮帮我......

提前致谢

我的源代码是：

---

<script type="text/javascript">
<!--
var adOpenDynamic = 2;
var adLockOptimistic = 3;

/* Path of database.
*/
var strDbPath = "..\\SRVGdb.mdb";

/*
Here is the ConnectionString for Microsoft Access.
If you want to use SQL or other databases, you hav to change the connection string..
eg: SQL => var conn_str = "Provider=sqloledb; Data Source=itdev; Initial Catalog=pubs; User ID=sa;Password=yourpassword";
*/
var conn_str = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + strDbPath;

function getAdoDb(strAdoType){
if (window.ActiveXObject){
return new ActiveXObject(strAdoType);
}
else{
return ActiveXObject(strAdoType);
}
}

function showReports(){
try{
var tablevar="<table width=\"100%\" border=\"1\">"
                    +"  <tr><td></td>"
                    +"  </tr>";

rs.MoveFirst();

while(!rs.eof) {

    if(document.layers){
        document.getElementById("one").open();

        document.getElementById("one").close();

Answer 1

ActiveX对象是Internet Explorer专有的。您必须找到等效对象才能在其他浏览器中执行相同的功能（如果有的话）。你必须展示你正在做的事情，以便更具体地了解如何让它发挥作用。

假设您指的是Ajax，请使用支持XMLHttpRequest的抽象XHR函数和IE特定的ActiveX对象。

/** XHConn - Simple XMLHTTP Interface - bfults@gmail.com - 2005-04-08        **
 ** Code licensed under Creative Commons Attribution-ShareAlike License      **
 ** http://creativecommons.org/licenses/by-sa/2.0/                           **/
function XHConn()
{
  var xmlhttp, bComplete = false;
  try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); }
  catch (e) { try { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); }
  catch (e) { try { xmlhttp = new XMLHttpRequest(); }
  catch (e) { xmlhttp = false; }}}
  if (!xmlhttp) return null;
  this.connect = function(sURL, sMethod, sVars, fnDone)
  {
    if (!xmlhttp) return false;
    bComplete = false;
    sMethod = sMethod.toUpperCase();

    try {
      if (sMethod == "GET")
      {
        xmlhttp.open(sMethod, sURL+"?"+sVars, true);
        sVars = "";
      }
      else
      {
        xmlhttp.open(sMethod, sURL, true);
        xmlhttp.setRequestHeader("Method", "POST "+sURL+" HTTP/1.1");
        xmlhttp.setRequestHeader("Content-Type",
          "application/x-www-form-urlencoded");
      }
      xmlhttp.onreadystatechange = function(){
        if (xmlhttp.readyState == 4 && !bComplete)
        {
          bComplete = true;
          fnDone(xmlhttp);
        }};
      xmlhttp.send(sVars);
    }
    catch(z) { return false; }
    return true;
  };
  return this;
}


/* assuming you already have XHConn.js included in your HTML file */

var myConn = new XHConn();

if (!myConn) alert("XMLHTTP not available. Try a newer/better browser.");

var fnWhenDone = function (oXML) { alert(oXML.responseText); };

myConn.connect("mypage.php", "POST", "foo=bar&baz=qux", fnWhenDone);

Firefox中没有ActiveX支持，无法连接到Access数据库。这些是Microsoft专有技术。

我不相信还有浏览器端的ODBC支持;关于这一点我可能是错的。
