無法使用javascript方法中的submit（）提交表單

無法使用javascript方法中的提交方法提交表單& onclick事件
對按鈕元素甚至嘗試使用表單標記中的onsubmit事件。需要不提交細節的原因。您可以複製代碼&運行它更多清晰度。無法使用javascript方法中的submit（）提交表單

'的onclick = 「validatForm」'注意從函數名失蹤'e'。 – marekful 2013-02-11 12:58:56

表單中的跨度不是表單對象。 – mplungjan 2013-02-11 13:05:33

更正了功能名稱，但沒有起作用@MarcellFülöp – user2042156 2013-02-11 13:08:26

請檢查您的調用的onclick功能，它的拼寫錯誤爲 'validatForm' 而不是 'validateForm'

這裏函數（）是一個關鍵字？ – user2042156 2013-02-11 13:14:27

@mplungjian檢查...沒有工作... – user2042156 2013-02-11 13:17:13

更新 - 請參閱演示 - 我使用匿名函數來驗證窗體 - 分配頁面的onload – mplungjan 2013-02-11 13:22:34

除了拼寫在你的代碼中已經發現的問題還有一個。您的按鈕提交輸入的標籤是： <input type="button" value="SUBMIT" onclick="validatForm(this.form)"></input>

而且必須是： <input type="submit" value="SUBMIT" onclick="validateForm(this.form)"/>
