AJAX 熱火的不得了,主要由於Mozilla、Opera 等主流瀏覽器都支援了 XMLHttpRequest 物件,這個微軟在 IE 5.0 推出 ActiveX 時就存在的物件,名為 XMLHTTP,只不過只有 IE 瀏覽器支援 new ActiveXObject("Microsoft.XMLHTTP") 語法,因此流通不廣。

事實上 XMLHTTP 在 ASP 中的使用,和 AJAX 所差無幾,這裡簡單使用 XMLHTTP 檢查是否某一個連結存在。

在 AJAX 中,跨網域連線是不允許的,但在 ASP 中的 XMLHTTP 物件,這方面就沒那麼嚴謹,本例取檔名 linkCheck.asp,使用語法如:





  • '宣告變數
  • Dim URLs, xml
  • '建立物件
  • Set xml = Server.CreateObject ("Microsoft.XMLHTTP")
  • '要檢查的網址
  • URLs = Request("url")
  • On Error Resume Next
  • xml.Open "GET", URLs, false
  • xml.Send
  • IF xml.status=404 Then
    • Response.Write "找不到頁面"
  • ELSEIF xml.status=200 Then
    • Response.Write "頁面連線正常"
  • ELSE
    • Response.Write "連線發生錯誤,代碼 "&xml.status
  • END IF
  • '關閉物件
  • Set xml = Nothing

Hi just wanted to give you a brief heads up and let you know a few of the pictures aren't loading properly.
I'm not sure why but I think its a linking issue. I've tried it in two different browsers and both show the same results.

I do not know if it's just me or if everyone else encountering problems with your site.
It looks like some of the written text in your
content are running off the screen. Can somebody else please
provide feedback and let me know if this is happening to them too?
This might be a issue with my internet browser because
I've had this happen before. Thank you

Hey I know this is off topic but I was wondering
if you knew of any widgets I could add to my blog that automatically tweet my newest twitter updates.
I've been looking for a plug-in like this for quite
some time and was hoping maybe you would have some experience with
something like this. Please let me know if you run into anything.
I truly enjoy reading your blog and I look forward to your new updates.

I have been browsing on-line more than three hours today, but I never found any fascinating article like yours.
It's pretty price enough for me. In my view, if all webmasters and bloggers made excellent content as you probably did, the internet will be
much more helpful than ever before.
