问题
I'm using a javascript syntax highlighter (http://alexgorbatchev.com/SyntaxHighlighter/). I think this one is very famous.
in my js, I use ajax to get code samples and then initialize syntax highlighter. When I call the same ajax call with a different parameter, it returns a different code sample. The problem is that I can't replace syntax highlighter's content. I looked up its API list, but I can't find an API to update or replace its content.
Please advise me.

Just empty the wrapper element, put the new content inside, and then run syntax highlighter on that new code.
There shouldn't be any memory issues. Afaik, Syntax Highlighter simply creates a DOM structure (a table with DIV's, etc.) based on your code block. When you remove that table from the DOM (for instance wrapper.innerHTML = '';), all those elements are garbage collected.
