利用XMLHTTP 從其他頁面獲取數據
編輯:AJAX詳解     

我們在編寫ASP代碼的時候,大家都知道可以通過post或者get獲得form表單的數據,那麼我們如何直接獲得其他頁面上的數據呢?這就要借助xmlhttp協議了。xmlhttp是XMLdom技術的一部分。

下面的代碼就是一個很簡單的例子,我們利用XMLhttp技術,把http://www.codetoad.com/站點首頁的代碼以XML的形式完全獲取,並且在頁面中輸出。

<%
  Dim objXMLHTTP, XML
  Set xml = Server.CreateObject("Microsoft.XMLHTTP")
 
  XML.Open "GET", "http://www.codetoad.com/", False
  ' Pull the data from the web page
  XML.Send

  Response.write "Here's the Html we now have in our XML object"
  Response.write "<BR><BR><BR>"
  Response.Write "<xmp>"
  Response.Write XML.responseText
  Response.Write "</xmp>"
  Response.write "<BR><BR><BR>"
 Response.write " Now here's how the page looks:<BR><BR>"
  Response.Write XML.responseText
 
  Set XML = Nothing
%>

下面是另一個實例

<%
dim objHTTP , objXML , objXSL
set objHTTP = Server.CreateObject("Microsoft.XMLHTTP")
objHTTP.open "GET", "http://p.moreover.com/CGI-local/page?c=Pop%20music%20revIEws&o=XML", false
objHTTP.send
set objXML = objHTTP.responseXML
set objXSL=Server.CreateObject("microsoft.XMLdom")
objXSL.async=false

objXSL.load(Server.MapPath("style.xsl"))

if (objXSL.parseError.errorCode = 0) then
    Response.Write(objXML.transformnode(objXSL))
else
    Response.Write "Error: " & objXSL.parseError.reason & " URL:" & objXSL.url
end if

Set objHTTP = Nothing
Set objXML = Nothing
Set objXSL = Nothing
%>

style.xsl:
<xsl:stylesheet XMLns:xsl="http://www.w3.org/TR/WD-xsl">
    <xsl:template match="/">
