问题描述

我想访问XMLHTT prequest.open方法我甚至包括netscape.security.PrivilegeManager.enablePrivilege(​​UniversalBrowserRead);

I am trying to access XMLHTTPRequest.open Method I have even included netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");

但仍是其无法正常工作。

but still its not working.

我使用JavaScript和HTML访问的WebService。

I am using javascript and HTML to access the WebService.

任何帮助将是真正伟大

code



<html>
  <Head> 
    <Title>Calling A WebService from HTML </Title>
  </Head>

<Body onload='GetDataFrmWS()'>
  <form name="Form1" id="Form1" runat="server" method="post">
    <div id="DisplayData" > </div>
    <div id="Menu2"></div>

  </form>

<script language='javascript'>

var objHttp;
var objXmlDoc;

function GetDataFrmWS()
{
  alert('I M Here');
  var func = getDataFromWS();

}


function getDataFromWS()
{

  if(window.ActiveXObject)
  {
     try 
        {
        objHttp = new ActiveXObject('Msxml2.XMLHTTP');

    }
 catch (ex)
 {
  objHttp = new ActiveXObject('Microsoft.XMLHTTP');
 }

} 否则,如果(window.XMLHtt prequest) {   objHttp =新window.XMLHtt prequest();   netscape.security.PrivilegeManager.enablePrivilege(​​UniversalBrowserRead); }

} else if (window.XMLHttpRequest) { objHttp = new window.XMLHttpRequest(); netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead"); }

strEnvelope ='&LT;肥皂:信封的xmlns:XSI =htt​​p://www.w3.org/2001/XMLSchema-instance的xmlns:XSD =htt​​p://www.w3.org/2001/XMLSchema XMLNS:肥皂=http://schemas.xmlsoap.org/soap/envelope/&GT; +'&LT;肥皂:身体与GT; +'&LT;的HelloWorld的xmlns =htt​​p://tempuri.org/&GT; +'&LT;虚拟的xsi:type =XSD:字符串&GT;你好&LT; /假&GT;+'&LT; / HelloWorld的&GT;+'&LT; / SOAP:身体与GT; +'&LT; /肥皂:信封&GT; ;

变种szUrl;szUrl =' HTTP://kamadhenu/Quoteme/GetCategories.asmx OP =的HelloWorld ' ;objHttp.onreadystatechange =用handleResponse;

var szUrl;szUrl = 'http://kamadhenu/Quoteme/GetCategories.asmx?op=HelloWorld';objHttp.onreadystatechange = HandleResponse;

objHttp.open(POST,szUrl,真正的);objHttp.setRequestHeader(内容类型,为text / xml');objHttp.setRequestHeader(SOAPAction报',' http://tempuri.org/HelloWorld ');objHttp.send(strEnvelope);

objHttp.open('POST', szUrl, true);objHttp.setRequestHeader('Content-Type', 'text/xml');objHttp.setRequestHeader('SOAPAction','http://tempuri.org/HelloWorld');objHttp.send(strEnvelope);

}

功能用handleResponse(){
如果(objHttp.readyState == 4) {

function HandleResponse(){
if (objHttp.readyState == 4) {

如果(window.ActiveXObject)   {     objXmlDoc =新的ActiveXObject(Microsoft.XMLDOM);     objXmlDoc.async =假;     objXmlDoc.loadXML(objHttp.responseText);     VAR nodeSelect = objXmlDoc.getElementsByTagName(菜单1)项目(0)。     。VAR菜单2 = objXmlDoc.getElementsByTagName(菜单2)项目(0);     的document.getElementById('DisplayData)的innerHTML = nodeSelect.text;
     的document.getElementById('菜单2)的innerHTML = Menu2.text。    }  其他   {    VAR文本= objHttp.responseText;    VAR分析器=新的DOMParser();    objXmlDoc = parser.parseFromString(文字,为text / xml');    变种Value=objXmlDoc.documentElement.childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].nodeValue;    变种Menu2=objXmlDoc.documentElement.childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[1].childNodes[0].nodeValue;    变种Menu3=objXmlDoc.documentElement.childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[1].childNodes[1].nodeValue;    的document.getElementById('DisplayData)的innerHTML =价值;
    的document.getElementById('菜单2)的innerHTML =菜单2。    的document.getElementById('菜单2)的innerHTML + =菜单3。   } }

if (window.ActiveXObject) { objXmlDoc = new ActiveXObject("Microsoft.XMLDOM"); objXmlDoc.async="false"; objXmlDoc.loadXML(objHttp.responseText); var nodeSelect = objXmlDoc.getElementsByTagName("Menu1").item(0); var Menu2=objXmlDoc.getElementsByTagName("Menu2").item(0); document.getElementById('DisplayData').innerHTML=nodeSelect.text;
document.getElementById('Menu2').innerHTML=Menu2.text; } else { var Text=objHttp.responseText; var parser=new DOMParser(); objXmlDoc = parser.parseFromString(Text,'text/xml'); var Value=objXmlDoc.documentElement.childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].nodeValue; var Menu2=objXmlDoc.documentElement.childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[1].childNodes[0].nodeValue; var Menu3=objXmlDoc.documentElement.childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[1].childNodes[1].nodeValue; document.getElementById('DisplayData').innerHTML=Value;

推荐答案

我用下面的code创建一个XML对象。它已被设计来处理所有的浏览器(特别是IE和非IE)的

Browser Independent code for XML HTTPRequest

I use the following code to create an XML object. It has been designed to handle all browsers (esp. IE and non IE)

/* Function to create an XMLHTTP object for all browsers */
function getXMLHTTPObject(){
    var xmlHttp;
    try{
        // Firefox, Opera 8.0+, Safari
        xmlHttp=new XMLHttpRequest();
    } catch (e){
        // Internet Explorer
        try{
            xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
        }catch (e){
            try{
                xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
            }catch (e){
                alert("Your browser does not support AJAX!");
                return false;
            }
        }
    }
    return xmlHttp;
}       
/* End Function */

P.S。您code的问题是无法读取。请格式化

P.S. You code in the question is not readable. Pls format it
