Interactive rating component

Felt like there were two approaches to making this single-site app: overwriting the contents of a container with new html or using the submit button to make the first container hidden and reveal the second container. Interested to know what everyone else would have chosen (I went for the latter, I'm not super confident with writing javascript that is impervious to malicious injection yet) also interested to know if there is a more universally accepted approach to this that I overlooked. Thanks.
