I have written this html:
<a href="#" class="addcomment">Add Comment</a>
<div id="addcomment">
<form name="comment" action="" method="post">
<input type="text" name="addcomment" size="80" />
<input type="submit" value="Comment">
</form>
What I want is when I click the "Add comment" then form should be displayed in place of "Add comment" just like on "stackoverflow". How can I make this happen??
