I'm trying to send a JavaScript variable to my Rails controller through an AJAX request in order to use the variable to find the right instance of my model.
I can get my controller to print this variable, but I have not been able to save it anywhere such as a partial.
Here is my js.erb file:
$(".single-item").on('afterChange', function(event, slick, currentSlide, nextSlide){
$.ajax({
url: 'update_description',
type: 'post',
data: {slideNumber: $(".single-item").slick('slickCurrentSlide')},
dataType: 'json',
success: function(data) {
}
});
And my controller file:
def index
@posts = Post.all
if params[:slideNumber] == nil
@slideNumber ||= 0
else
@slideNumber = params[:slideNumber]
end
puts @slideNumber
respond_to do |format|
format.html {}
format.js {}
end
end
This puts @slideNumber
in the controller correctly and prints the variable coming from JavaScript to console, however I am not able to pass it to a partial or to reuse it as a response from the JavaScript file. Am I missing something?
