I encountered some weird behaviour when using an ajax request to get a response from a rails controller action.
$.ajax({
type: 'GET',
url: '/notifications',
success: function(result) {
eval(result);
}
});
def index
respond_to do |format|
format.html { redirect_to root_url, alert: 'Page not accessible' }
format.js
end
end
So this respond_to block works fine when using requests with rails' remote: true
option, but with the ajax call it just redirects the request to root_url
.
When specifying json
as dataType
of the Ajax request. The so returns the JavaScript just fine, but because it is not valid json
, eval()
does not run it.
Is there a way too either start a rails remote request from within JavaScript or specify a data type with which the returned JavaScript is executable?
Even specifying dataType: 'text/javascript',
in the ajax call does not do the trick.

So the request format that is coming to the controller is HTML
not JS
. Using dataType: 'script'
generates the request as JS
and should fix your problem.
$.ajax({
type: 'GET',
dataType: 'script',
url: '/notifications'
});
