如何选择定义值。如果我的产品的价值是1我想在1

Answer 1

一个活性按钮可以使用checked属性，从数据库/控制器枢转关值的，如下所示：

<input <%= "checked" if product == 1 %> id="bien_nb_piece_true" name="bien[nb_piece]" type="radio" autocomplete="off" value="1"/> 
<input <%= "checked" if product == 2 %> id="bien_nb_piece_true" name="bien[nb_piece]" type="radio" autocomplete="off" value="2"/> 
<input <%= "checked" if product == 3 %> id="bien_nb_piece_true" name="bien[nb_piece]" type="radio" autocomplete="off" value="3"/> 

等。
