正如你所知道做跨域XMLHTTP请求不允许在Internet Explorer的安全考虑。

As you know doing Cross Domain XMLHTTP requests is not allowed for security reasons under Internet Explorer.

我有一个WebBrowser控件，我用 DocumentText 而不是导航来一个网址。由于当前访问有关：空白时，页面会尝试做一个请求本身或其他域我收到访问被拒绝 JavaScript错误。

I have a WebBrowser Control and I'm using DocumentText instead of Navigate to a URL. Since the current domain is about:blank when the page tries to do a request to itself or other domain I'm getting Access is denied Javascript error.

即使当我使用导航如果Javascript的一个请求到另一个域这是行不通的。

Even when I use Navigate if the Javascript do a request to another domain it doesn't work.

我怎样才能解决这个？

这个HTML code应与WebBrowser控件：

This HTML code should work with WebBrowser Control:

<body>

<a href="javascript:getit('http://www.google.com')">this should work</a>
<div id="x"></div>

</body>

<script>
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;
}

function getit(url){
    var xmlhttp = new XHConn();
    var fnWhenDone = function (oXML) { document.getElementById('x').innerHTML = oXML.responseText; alert(oXML.responseText); };
    xmlhttp.connect(url, "GET", "", fnWhenDone);
}

</script>

我没有过的JavaScript / HTML code控制，我的应用程序只承载WebBrowser控件 *我发现了一些所谓的 CROSS_DOMAIN_DATA URL操作标志< /一>，不知道这是否是正确的方向。即使这是我不知道如何实现它。* 此外，如果你能回答这个问题：How设置当前document.domain的WebBrowser控件中，以避免出现访问被拒绝？这足以让我也。

I don't have control over Javascript / HTML code, my application only hosts a Webbrowser Control *I found something called CROSS_DOMAIN_DATA URL Action Flags, not sure if it's right direction. Even it's I'm not sure how to implement it.* Also if you can answer to this question : How to set current document.domain in WebBrowser Control to avoid "Access is denied"? that's enough for me as well.
