谷歌浏览器加载XML文件的问题

W3CSchool的教程中提供过一个loadXMLDoc函数:

 

  
   

    function
     loadXMLDoc(url) {
 
    var
     xmlDoc;
 
    try
    {
 xmlDoc
    =
    new
     ActiveXObject(
    "
    Microsoft.XMLDOM
    "
    );
 }
 
    catch
    (e){
 
    try
    {
 xmlDoc
    =
    document.implementation.createDocument(
    ""
    ,
    ""
    ,
    null
    );
 }
    catch
    (e){
 alert(e.message);
 
    return
    ;
 }
 }
 xmlDoc.async
    =
    false
    ;
 xmlDoc.load(url);
 
    return
     xmlDoc;
}
   

 

不过在谷歌浏览器中会出现如下错误:

Object #<a Document> has no method 'load'

所以为了适应谷歌浏览器只能用XMLHttpRequest对像再responseXML得到XML

修改后的loadXMLDoc函数如下:

 

  
   

    function
     loadXMLDoc(url) {
 
    var
     xmlDoc;
 
    try
    {
 xmlDoc
    =
    new
     ActiveXObject(
    "
    Microsoft.XMLDOM
    "
    );
 }
 
    catch
    (e){
 
    try
    {
 
    var
     oXmlHttp 
    =
     
    new
     XMLHttpRequest() ;
 oXmlHttp.open( 
    "
    GET
    "
    , url, 
    false
     ) ;
 oXmlHttp.send(
    null
    ) ; 
 
    return
     oXmlHttp.responseXML;
 }
    catch
    (e){
 
    return
    ;
 }
 }
 xmlDoc.async
    =
    false
    ;
 xmlDoc.load(url);
 
    return
     xmlDoc;
}
