It does not get submitted because it is not part of the form.  It is a standalone textarea.  It might work if you rewrite the innder HTML of the form with the textarea included.  

str+=you new element here;

That might work.  or you might have to put the whole form inside a Div and rewrite the innerHTML for that.



thx u ..Cd& .. you have correct my page .. but I want to ask to you  if I have 2 tables ... and I want to insert this textarea on the 1 table ..can possible or not ??

<table1 id="tbl1">
. --- > insert to here ???

I give a top quality answer quickly and you grade it B?  

...and you ask for additional help.  

You'll find that grading like that will make top-experts reluctant to help you, but
to answer the followup:

Just put a div in the cell where you want to put the textarea, and then re-write the
innerHTML of the div.

In the future I would recommend that when you intend to give less than an A grade you
let the expert know what you need for it to be an A and give them a chance to improve
the answer.
