hello friends have a look on my attechments..

the rows are dynamically genrated from database..!! In column Amount user fills values....!!!

when user click on add ledger.. a new popup window will open with a form... after adding ledger and closing the popup window...!! the parent page will refresh.. so that new ledger can be seen in the list...!!

but now problem comes that when page refresh.. the values which user filled got vanished...!! :(

so i wondering is there any way to hold the values..!!

what if i take particular column in div... and after close the popup..i made refresh that div only....!!!

is it possible..!!

waiting for positive reply :)

Sorry i am unable to open your attached file. Can you post the actual code, or would you prefer a different sample?

<?while($row=mysql_fetch_array($result))
{?>
<td><?echo $row['ledgerName']; ?></td>// column name Ledgers
<td><input type="textbox"></td>// column name Amount
<?}?>
<input type='button' value='add New ledger' onclick='myPopWindow();'>

<input type='submit'>

Now Suppose there are 5 records in database.. means five rows will appear on the page.. user start filling the values in textbox... after filling the value... user want to add a new Ledger..!! then he will click on Add new ledger button.. and a pop-up window will appear..and after adding the ledger... the parent page(in which i m showing the listing..) will refresh.. so that new ledger can seen in the list..... but the values which user fill disappears on page refresh....!!!

so i thought instead of full page refresh... LedgerName column in div and refresh that part only..!!

Since you've provided me with insufficient code, then i will just have to mimic everything on this demo.

To be able for this to work, you must provide all valid variables and including querystring on each document, especially inside the ledger.php where it needs valid information, so it can provide valid results sent back to the AJAX request.

This program offers easy update's w/o reloading the actual page ( parent page ).

Here's the code for the mainpage:

Nice worK....!!
but i still want to know is there any to way refresh a particular div through ajax...!!!

With or w/o AJAX, you can update any portion of your page w/o reloading.

But since you're requesting it with AJAX, so here's a simple workaround to get you started.

I've used some text file, in which i put all the ids of the div i need ( each id must be separated by a space or any delimeter that you prefer to use ).

Here's the content of of the ids.txt : div1 div2 div3 the testpage:
