我在 Rails 4.0 上。
我正在发送这样的事件(注意:remote=>true):
<%= button_to 'yes', {controller:'videos', action:'rate', id: video.hashed_id, yesno:'yes'}, {:remote=>true, :class=>"rate-btn yes-btn btn btn-default btn-sm"} %>
我的控制器如下所示:
def rate
video = Video.find_by( hashed_id: params[:id])
action = params[:yesno]
puts video.hashed_id
puts action
respond_to do |format|
if (action=='yes')
new_rating = video.rating==1 ? 0 : 1
video.update( is_new:0, rating: new_rating )
format.html { redirect_to controller:'projects', action: show, id: video.project.hashed_id }
format.json { head :no_content }
format.js { render :nothing=>true }
end
if (action=='no')
new_rating = video.rating==-1 ? 0 : -1
video.update( is_new:0, rating: new_rating )
format.html { redirect_to controller:'projects', action: show, id: video.project.hashed_id }
format.json { head :no_content }
format.js { render :nothing=>true }
end
end
end
我有点喜欢使用 format.json/format.html,因为我不完全理解应该从 AJAX 请求中应用哪一个。
在视图(按钮所在的位置)上,我有这个:
$(document).ready( function($) {
console.log('ready');
$(document).ajaxSuccess( function(data) {alert(data);} )
$(document).ajaxError( function(data) {alert(data);} )
$('.rate-btn').closest('form').on('ajax:success', function() {
console.log('ajax:success!');
});
$('.button_to').bind("ajax:success", function() {
console.log( 'test' );
});
});
单击按钮后,我进入ready
控制台,但无论我做什么,我都无法test
在控制台中显示。我错过了什么?
更新:
我在观看 /log/development.log 时尝试单击按钮,这就是我所看到的:

我是 Rails n00b,但对我来说看起来不错。
