但我需要每个选择都有一类CSS.
我没有在文档中找到如何将参数传递给帮助器,我尝试了几种方法,没有.
Rails查看：
@H_403_7@<%= f.date_select :birthday,:order => [:day,:month,:year],:start_year => 1910,:end_year => 2012,:html => {:class => ['day','month','year']} %>HTML输出：
@H_403_7@<select id="poll_user_birthday_3i" name="poll_user[birthday(3i)]"> <select id="poll_user_birthday_2i" name="poll_user[birthday(2i)]"> <select id="poll_user_birthday_1i" name="poll_user[birthday(1i)]">像我这样的HTML输出：
@H_403_7@<select id="poll_user_birthday_3i" name="poll_user[birthday(3i)]" class="day"> <select id="poll_user_birthday_2i" name="poll_user[birthday(2i)]" class="month"> <select id="poll_user_birthday_1i" name="poll_user[birthday(1i)]" class="year">谢谢！
解决方法

视图
@H_403_7@<span class="datetime"> <%= f.date_select :birthdate,:end_year => 2012 %></span>CSS
@H_403_7@.datetime select:nth-child(1){ width: 130px; text-indent: 15px; } .datetime select:nth-child(2) { width: 200px; text-indent: 5px; } .datetime select:nth-child(3) { width: 110px; text-indent: 15px; }
