I am making an ajax call to an action and then I in the file of action.js.erb I am updating the html of my div by rendering the same partial but with updated values but partial is not rendering updated values. Kindly let me know what I am doing wrong . console is also showing no error at all

Answer 1

Try adding an alert message before and after you call .html(). Do both alerts pop up? If so, that means the issue most likely isn't with your javascript.

Answer 2

Yes this is a problem request must be of type "js", please provide how you are making ajax call? that is the view part of it

Answer 3

Why do you replace the existing values of <div id="performance"> </div> . Try to append the new values by using append method in js.
