Retrieve value of dynamic generated textarea in jQuery?

Question

<div id="post">
  <form name="postComment" id="commentPost6" action="javascript:void(0);" method="post"
    target="_top" onsubmit="return commentPost(6)">
     <textarea name="comment" id="comment6" class="commentText" 
        cols="10" rows="3" accesskey="1">
     </textarea><br>
     <input type="submit" name="submit" id="commentpost" value="Submit" accesskey="2">
  </form>
</div>

this is my post div tag, i have multiple div tag with same id="post", the form and fields are dynamically generated and id of both form and textarea are unique, so that there is no problem in retriving those values, on click of submit, i call commentPost method.

function commentPost(postId)
{
    alert("Inside commentpost");
    //how to retrive/access value of textarea here

}

how to get value of textarea ?? and just in case

Yes, i know it's not valid HTML to have multiple elements with the same ID.

Answer 1

$('#comment'+postId).val();

Why aren't you simply using classes instead of ids? (post)
