js.erb不执行javascript，但已处理过的rails [英] js.erb not executing javascript but is processed rails

问题描述

我正在尝试使用will_paginate或kaminari与Ajax进行分页.

I'm trying to get my pagination working with Ajax, using either will_paginate or kaminari.

当我点击分页链接时，我的日志显示

When I hit pagination link my log says

Processing by Instructor::FullDashboardController#pupil_leads as JS

和

Rendered instructor/full_dashboard/pupil_leads.js.erb within layouts/main (0.1ms)

但是js无效.因此，为了测试它，我写了

But the js has no effect. So to test it I wrote

console.log("Hello");
<%logger.debug "This is the js file"%>
alert('Hello Rails');

在js.erb文件中，在日志中按预期方式看到了This is the js file，但是浏览器中的js控制台中没有任何内容，并且警报未显示.所以我知道文件正在处理中，因为我的logger.debug有效，但是没有js.

In the js.erb file, in my log I see This is the js file as expected, but there is nothing in js console in my browser and the alert doesn't show. So I know the file is being processed, as my logger.debug works but there is no js.

如何进一步解决此问题?

How can I further troubleshoot this?

Rails 4.1

Rails 4.1

Ruby 2.1

完全破折号控制器

class Instructor::FullDashboardController < ApplicationController
   layout 'main'
...
   def pupil_leads
     @ivar = Model.where("something = ?", some_object.id).order("created_at desc").page(params[:page]).per(10)
     respond_to do |f|
       f.js { render :content_type => 'text/javascript' }
       f.html
     end
  end

推荐答案

在渲染块中添加layout: false选项:

def pupil_leads
   # some code here
  respond_to do |f|
    f.js { render layout: false, content_type: 'text/javascript' }
    f.html
  end
end

_{出于某种原因，Rails无法将请求识别为xhr，我还注意到必须完全指定视图扩展名(.erb.html或.slim).}

_{For some reason Rails don't recognize request as xhr, I also watched that the views extension (.erb.html or .slim) must be specified in full.}
