因此,這裏是我的.haml代碼:Ruby on Rails的 - JQuery的空字段
%h1= t('.title')
%p= t('.contact_us')
= form_tag request_contact_path, method: 'post' do
= label_tag :name, t('.name')
= text_field_tag :name, '', title: t('.enter_name'), size: 30
= label_tag :email, t('.email')
= email_field_tag :email, '', title: t('.enter_email')
= label_tag :song, t('.song')
= text_field_tag :song, '', title: t('.enter_song')
= label_tag :artist, t('.artist')
= text_field_tag :artist, '', title: t('.enter_artist')
= label_tag :album, t('.album')
= text_field_tag :album, '', title: t('.enter_album')
= label_tag :reason, t('.reason')
= text_area_tag :reason, '', title: t('.enter_reason')
= label_tag :message, t('.message')
= text_area_tag :message, '', title: t('.enter_message')
= submit_tag t('.submit')
=link_to t('Cancel'), root_path
我試圖使用jQuery(而且必須是JQuery的!),使按鈕不能選擇提交(或一些錯誤拋出)如果至少電子郵件字段是空的,有沒有一種可能的方法來實現這一目標?我會非常精明的幫助或提示
