Ruby ajax实现二级联动菜单
view页面代码：
<label style="font:bold;">Season<span class="required">*</span></label>
<%= select('season', 'id',
Season.all.collect {|t| }, {:include_blank => true},
{"onchange" => remote_function(
:with => "'season_id='+value", //传递的参数
:update => 'series_select', //指定更新的div
:url => {:controller => :projects, :action => :select_series})})%>
<div id="series_select" style="width: 367px;">
</div>
controller代码：
def select_series
@series = Series.find(:all, :conditions => ["season_id = ?", params[:season_id]]).collect { |series| }
render :partial => "projects/select_series" //用projects/select_series更新 div id="series_select"
end
