jquery post
<br />$.post(url, data, callback, type) <br /><br />This is an easy way to send a simple POST request to a server without having to use the more complex $.ajax function. It allows a single callback function to be specified that will be executed when the request is complete (and only if the response has a successful response code). The returned data format can be specified by the fourth paramater. If you need to have both error and success callbacks, you may want to use $.ajax. $.post is a (simplified) wrapper function for $.ajax.<br /><br /> $(document).ready(function(){<br /> $("#new_forum_comment form").submit(function(){<br /> $.post($(this).attr("action")+'.js', $(this).serialize(), null, "script");<br /> return false;<br /> })<br /> })
