loadxmldoc.js

介绍了javascript的常用的函数

function loadXMLDoc(dname)
{
  var xmldoc;
  //IE浏览器
  if (window.ActiveXObject)
  {
    //通过createmxxmldoc函数返回一个xmldoc对象
     xmldoc = createmxxmldoc();
	 //xmldoc = new ActiveXObject("Microsoft.XMLDOM");
  }
  //Mozilla Firefox浏览器
  else if (document.implementation 
&& document.implementation.createDocument)
  {
    //创建一个xmldom对象
    xmlDoc=document.implementation.createDocument("","",null); 
  }
  else
  {
    alert("浏览器不支持创建DOM对象");
  }
  xmldoc.async=false;
  xmldoc.load(dname);
//如果打开文件出错
  if (xmldoc.parseError.errorCode != 0) { 
    var myErr = xmldoc.parseError;
    document.write("加载文件出现错误： " + myErr.reason);
  }
  return xmldoc;
}
function createmxxmldoc(){
   var allxmlvers 
= ["MSXML2.DOMDocument5.0","MSXML2.DOMDocument4.0",
"MSXML2.DOMDocument3.0","MSXML2.DOMDocument", 
"Microsoft.XMLDOM"];
   for(var i=0;i<allxmlvers.length;i++){
try{
   //创建xml dom对象
        var xmldoc = new ActiveXObject(allxmlvers[i]); 
        return (xmldoc);
     }
      catch(exp){
		  //错误
      }
   }
   throw new Error("您需要安装ActiveX的MSXML库");
}
