In the Rails environment, it is important to verify that the data sent through $.post method in jQuery is correctly

I’m facing an issue with my jQuery script when trying to post data as shown below:

$.post({
    $('div#location_select').data('cities-path'),
    { location_string: $('input#city_name').val() },
});

Although this code works, the server inexplicably recognizes it as an HTML request instead of a JS request. What could be causing this? Here's the block in my controller that handles the response:

if @city.save
    respond_to do |format|
        format.html { redirect_to @city }
        format.json { render :json => @city, :status => :ok }
    end
else
    respond_to do |format|
        format.html { render :new }
        format.json { render :json => { :error => "Incorrect location format, please input a city and state or country, separated by a comma." }, :status => :unprocessable_entity }
    end
end

What steps can I take to ensure that an Ajax request is correctly reaching the Controller and being processed by the format.js responder?


Update: Making a simple modification from $.post to $.ajax along with specifying the data type appears to resolve the issue:

$.ajax({
  type: 'POST',
  url: $('div#location_select').data('cities-path'),
  data: { location_string: $('input#city_name').val() },
  dataType: 'json'
});

Answer №1

Is the format being passed from the route in routes.rb?

"controller/action/(.:format)"
