Since Alex released his js quick tags – it seemed like the perfect thing to add to the comments form so that people could put in the html tags more easily. However, while his script is really powerful – just for the comments form, it's more than what's needed. So I stripped it down to the most basic version – using only the most common HTML tags used in comments – italic, bold, and links.
Here are the instructions on how to integrate it into your (wordpress) comments:
First and foremost – if you want to add code, or use the full version – you can download that from Alex's site.
To use the "mini" version I made:
1) Download the js file and upload it to the root of your domain.
2) Open up your wp-comments.php page… Look for the beginning of the comments form – (search for <form in the file) and put this just above it:
<script src="/js_quicktags-mini.js" type="text/javascript"></script>
Look for the text area field for comments which looks like this <textarea name="comment" id="comment" cols="40" rows="6" tabindex="4"></textarea> and add this directly above it:
<script type="text/javascript">edToolbar();</script>
And add this BELOW the textarea field:
<script type="text/javascript">var edCanvas = document.getElementById('comment');</script>
This is the method I'm using on this site – although I added the "h3" tag just for the one I use, since that's what I use to stylize code on this site. You can easily add more… or start from scratch using Alex's.
