Question

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"> ?

Answer 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.
