.js.erb文件中的转义html问题 [英] Issues with escaped html in .js.erb file

问题描述

我有一个包含以下行的.js.erb文件

$（＃<％=
（<％=
escape_javascript（link_to（pluralize（@ count，'tag'），
user_tags_path（它显示

> < a href = / users / 1 / tags> 1 taga>


而不是

1标签

当我运行rails 3.0.4时，这用于工作，但现在它不会现在，米跑轨3.0.8。我发现我需要在其他地方使用 auto_link 添加 .html_safe ，否则我会得到相同的结果问题。

我如何得到它，以便它不会转义这个html？

我从来不喜欢用这样的红宝石插入你的JS。它总是会导致难以理解的毛茸茸。

相反，将数据转储为JS，然后将其作为原生JavaScript使用。

  var user =<％= {
：id => current_user.id，
：path => user_tags_path（current_user），
：link_text => pluralize（@ count，'tag'），
} .to_json％>; 
 
 var link = $（'< a>'）。attr（'href'，user.path）.text（user.link_text）; 
 $（'＃user'+ user.id +'_following'）。html（link）; 
  

在我看来，它更容易理解并完全避免HTML问题，因为HTML不是在你的ruby表达式中。

I have a .js.erb file that has the following line

$("#<%= "user#{current_user.id}_following" %>").html("<%= escape_javascript(link_to(pluralize(@count,'tag'), user_tags_path(current_user))) %>")

It displays

<a href=/users/1/tags>1 taga>

Instead of

1 tag

This used to work when I was running rails 3.0.4 but now it doesn't now that I'm running rails 3.0.8. I found that I needed to add .html_safe in other places that I had been using auto_link or I would get the same problem.

How do I get it so that it won't escape this html?

解决方案

I never liked interpolating your JS with ruby like this. It always leads to hard to understand hairyness.

Instead, dump your data into JS on it's own as JSON, then simply use the data as native javascript.

var user = <%= {
  :id => current_user.id,
  :path => user_tags_path(current_user),
  :link_text => pluralize(@count,'tag'),
}.to_json %>;

var link = $('<a>').attr('href', user.path).text(user.link_text);
$('#user' + user.id + '_following').html(link);

Which, in my opinion, is far more understandable and completely dodges any HTML issues since the HTML is not in your ruby expression at all.
