Rails3呈现与文本/ html内容类型，而不是文本/ javascript中js.erb模板

问题描述

我在建设有3.0.0.beta3一个新的应用程序。我只是试图呈现一个js.erb模板Ajax请求以下操作（在publications_controller.rb）：

I'm building a new app with 3.0.0.beta3. I simply try to render a js.erb template to an Ajax request for the following action (in publications_controller.rb):

def get_pubmed_data
    entry = Bio::PubMed.query(params[:pmid])# searches PubMed and get entry
    @publication = Bio::MEDLINE.new(entry) # creates Bio::MEDLINE object from entry text
    flash[:warning] = "No publication found."if @publication.title.blank? and @publication.authors.blank? and @publication.journal.blank?
    respond_to do |format|
        format.js
    end
end

目前，我get_pubmed_data.js.erb模板就是

Currently, my get_pubmed_data.js.erb template is simply

alert('<%= @publication.title %>')

服务器响应与以下

The server is responding with the following

alert('Evidence for a herpes simplex virus-specific factor controlling the transcription of deoxypyrimidine kinase.')

这是完全正常的，只是没有发生在浏览器中，可能是因为内容类型的响应是，而不是如图所示的响应头在这里部分转载文/ JavaScript的text / html的：

which is perfectly fine except that nothing happen in the browser, probably because the content-type of the response is 'text/html' instead of 'text/javascript' as shown by the response header partially reproduced here:

Status 200
Keep-Alive timeout=5, max=100
Connection Keep-Alive
Transfer-Encoding chunked
Content-Type text/html; charset=utf-8

这是一个错误还是我失去了一些东西？感谢您的帮助！

Is this a bug or am I missing something? Thanks for your help!

推荐答案

我终于能迫使它得到正确的内​​容类型的响应：

I finally was able to get the right content-type in the response by forcing it with:

respond_to do |format|
    format.js {render :content_type => 'text/javascript'}
end
