问题
I am using a Rails 4 application. I installed some JavaScript plugin files in "vendor/assets/javascripts", and some in "app/assets/javascripts" where I have some files that are invoking methods from the vendor files.
No methods from these are recognized and it seems that "app/assets/javascripts" files are loaded before "vendor/assets/javascripts" files. How can I deal with that?
For information my "application.js" calls:
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require rails.validations
//= require_tree .
and I am using gem 'jquery-rails'.
回答1:
Any files in your vendor tree that you need must be required explicitly in your "application.js". It will pull in all the JavaScript in your "app/assets/" tree using the "require_tree".
You probably need to update your file to look something more like this:
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require rails.validations
//= require that_file_from_vendor_assets
//= require that_other_file_from_vendor_assets
//= require_tree .
where that_file_from_vendor_assets is the vendor JavaScript that you need to be loaded up before it gets to your "app/assets/javascript" files.
回答2:
Just change
//=require_tree .
like this:
//= require_self
Then files will be imported in the order of you put them to your application.js file.
And don't forget <%= javascript_include_tag "application"%> in your layout file.
