问题
In Rails, both the javascript_tag and javascript_include_tag render the type attribute as
type="text/javascript"
I need to customize this attribute. Our application uses Slim syntax which makes this a little more difficult.
script src="mathjax_config" type="text/x-mathjax-config"
^ doesn't error but doesn't even include the file
javascript_tag[type="text/x-mathjax-config"] javascript code here
^ throws an error
I'm hoping to avoid breaking the file away from slim.
Ruby version 1.9.3 Rails version 3.2.3
回答1:
Since you are modifying the type attribute you would either need to override the javascript_tag helper or write your own for that to work. This syntax isn't as elegant but should work:
script src=asset_path("mathjax_config") type="text/x-mathjax-config"
Note that this is slim/haml syntax - YMMV in erb.
回答2:
The file not being included is not Slims fault. Slim is agnostic to the content of the attributes, so it will happily render
script src="mathjax_config" type="text/x-mathjax-config"
into
<script src="mathjax_config" type="text/x-mathjax-config"></script>
Also, as far as I know, the browsers should happily load scripts with types other than "text/javascript" and you should be able to access them using their id.
Your approach is correct and the script not being included must have a different reason (like the file specified in src cannot be found).
