Assuming we have a comment textarea where the user can enter this code:
[quote="comment-1"]
How can I replace that code before the form submits with the actual html content from <div id="comment-1"> ?

You could try something like this:
var text = $('textarea').val();
text = text.replace(/\[quote="comment-(\d+)"\]/g, function(str,p1) { return $('#comment-' + p1).text(); });
$('textarea').val(text);
It should match agains any numbered quote in the format you gave.

You can use regular expressions:
text = text.replace(/\[quote="([a-z0-9-]+)"]/gi,
function(s, id) { return $('#' + id).text(); }
);

If I understand you correctly, you wish to replace something like '[quote="comment-1"]' with ''.
In JavaScript:
// Where textarea is the reference to the textarea, as returned by document.getElementById
var text = textarea.value;
text = text.replace(/\[quote\="(comment\-1)"\]/g, '<div id="$1">');
In jQuery:
// Where textarea is the reference to the textarea, as returned by $()
var text = textarea.val();
text = text.replace(/\[quote\="(comment\-1)"\]/, '<div id="$1">');
Hope this helps!
