Javascript的局部（Ruby on Rails的） [英] Javascript in partial (Ruby on Rails)

问题描述

例如我有很多意见呈现担任这个职务。

For example i have many comments rendered for the post.

<%= render post.comments %>

和在评论部分我了JavaScript至极会重复很多次，我有多少意见有

And in comments partial i have javascript wich will repeated so many times how many comments i have

_comment.html.erb

<div id="content_<%= comment.id %>"><%= comment.content %></div>
<scr​ipt>$("content_<%= comment.id %>").click(function() { a​lert(​'content of comment <%= comment.id %>'​) });</sc​ript>

什么是避免源$ C ​​$ C重复的JavaScript的最好方法是什么？ 我试图创建* _comment.js.erb *文件，并把JavaScript的存在，但我不知道如何使它发挥作用。

What is the best way to avoid repeating javascript in source code? I tried to create *_comment.js.erb* file and put javascript there, but i don't understand how to make it work.

任何人都可以请解释我如何解决这个问题？

Can anyone please explain me how to solve this problem?

推荐答案

您可以更改实施有下的应用程序/资产/ JavaScript的一个js文件里面你的脚本。改变脚本的选择器类的意见，而不是唯一的ID相匹配。如果需要的话，可以使用，而不是因为你现在做的服务器上做这个JavaScript来读取元素的内容。

You can change the implementation to have a single js file under app/assets/javascripts with your script inside. change the selector of the script to match the class of the comments instead of a unique ID. If required, use javascript to read the content of elements, instead of doing this on the server as you do now.
