Lab: Form and Action, Part II
Hand code a HTML or use Nvu to edit an HTML so that the webpage can send a request to Google like http://maps.google.com/maps?q=24.9586,+121.24114 Use Form CGI that includes action, input, and submit. Try a few different coordinates.
Lab Checking dead links
W3C Link Check 可以檢查 dead links, 而且只要輸入首頁, 就可以依據指定深度自動向下檢查, 而且也可以檢查對外連結(外站). Link Checker 首先要設定檢查深度(Check linked documents recursively, recursion depth=?), 如果沒有設定, 它就只有檢查首頁. 因此如果出現 deadlink, 就是在首頁. 如果你設定檢查深度, 它就會逐一檢查此深度內的每一頁, 在檢查某一頁開始時, 它會先顯示現正在檢查的 URL, 然後 在逐一爬行該頁內每個 link. 報表輸出很漂亮. 請參閱 http://validator.w3.org/checklink 請檢查三個你最常使用的網站, 看看連結的品質如何? 紀錄有錯誤連結 (HTTP Error 404) 的次數.
