How to pass an Incident ID to a Survey

Summary

Need to pass an Incident ID to a hidden field (question)

Content

Hi everyone,

I need to pass an incident ID to a survey page and retrieve it as one of the question's responses.

I've found out that I can use Javascript to capture the query string params and store it as a hidden question.

So, I can write the Javascript code to parse the paramenter, no problem, but my question is:  

How can I edit the question in HTML format, so that I can place the question inside a DIV (this way I can ID the HTML element in JS and also make it invisible)?
