一直習慣使用FireFox Firebug來除錯Javascript的我,

到了今天才發現原來IE也有自己的Javascript debugger,

以下是針對IE8 JS debugger的介紹. 雖然感覺上沒有Firebug來得好用,

但還是可以參考看看:

很多時候我們在下SQL語言時出錯卻一直找不出原因, 很多時候是因為在MYSQL內的COLUMN使用了reserved word 而造成的. 以下為MYSQL 的reserved word, 如果你在命名table.column時就要儘可能避開使用這些保留變數了.

環境: PHP4 + Apache4 + Windows
函數: iconv (http://tw.php.net/iconv)

最近有幫舊電腦寫程式,
發現PHP4預設不支援iconv, 先別擔心升級PHP5所帶來的其他風險,
其實是有辦法可以在PHP4下解決的:

1. 在C:\php\dll 底下有個 php_iconv.dll
2. 將此DLL放到 c:\Windows\system32\ 底下
3. 在C:\php\php.ini 將 extension 下的 php_iconv.dll Uncomment掉(把分號拿掉)
4. 重新啟動Apache.
5. It works!

在網路上找到的blink不是只能用於IE就是只相容於FF, 於是自己嘗試寫了一個JavaScript Blink的功能.
在IE8 及FF測試都沒問題. 閃爍的頻率在SetTimeout裡面可以設定, 1000表示1秒, 2000為2秒, 以此類推.



征才

剛在JavaScript寫程式時,
發現我的Ajax功能在FireFox可以跑成功, Firebug也偵測不出問題,
但用IE時卻出現錯誤, 顯示說某某行找不到物件.
後來去找了很久才知道原來問題出在一個平時很少注意的地方:

乍看之下可能會覺得以上兩行沒有甚麼差別, 但其實問題就在type的部分,
在FF是可以辨識成功的, 但在IE(測試環境IE8)的情況下就讀取不到Javascript.
所以以後要多注意囉.

PHP的File Upload功能固然強大, 但要滿足大量檔案上傳的需求仍需要搭配AJAX或是Flash object, 這篇文章就是要介紹一個好用的Flash Uploader, 讓你可以直接從Windows, 在同一個目錄下選取要上傳的檔案, 達成輕鬆上傳的目的.

SwfUpload

官方網站: http://swfupload.org/

範例: http://demo.swfupload.org/v220/index.htm
