我已要求下面的腳本form.php的:http://pastebin.com/kHiZ3gLY(我已經粘貼了以下完整的腳本)PHP腳本忽略輸入佔位符的文本字段
當我完成了第一套4場(保留另一2套他們的佔位符文本),並提交,我的var_dump輸出爲:
string '1|1|1|1
Height (cm)|Width (cm)|Length (cm)|Weight (kg)
Height (cm)|Width (cm)|Length (cm)|
' (length=133)
是否有可能,我可以用PHP/jQuery來「忽略」,已到位的佔位符的文本字段?所以我的輸出只是:
string '1|1|1|1' (length=7)
非常感謝任何幫手在這裏。

非常感謝您的回覆。你能確切地確認我應該把這個放在我的javascript代碼中嗎? – michaelmcgurk 2012-03-14 08:56:50
在你的問題的代碼中,你可以把它放在'jQuery'(函數($){'。 – drzax 2012-03-14 09:27:12
)非常感謝,drzax。剛剛嘗試... – michaelmcgurk 2012-03-14 09:58:01
