我使用date_select方法生成3个html选择,日,月和年.
但我需要每个选择都有一类CSS.
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：
- <%= f.date_select :birthday,:order => [:day,:month,:year],:start_year => 1910,:end_year => 2012,:html => {:class => ['day','month','year']} %>
HTML输出：
- <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：
- <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
他们解决这个问题的方式是用css
视图
- <span class="datetime"> <%= f.date_select :birthdate,:end_year => 2012 %></span>
CSS
- .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;
- }
