refresh div to retrieve information from database without refreshing wholepage

Question

I would like to refreash the div auto every 2 seconds without reloading the page how can i do this with jquery i did try some solutions but they did not work if

Answer 1

Change this line

$("#auto").load('conversation.php'+$hash)}, 2000);

to this

$("#auto").load('conversation.php'+'')}, 2000);

Because your $hash is PHP variable, but you are not inside a PHP block, you are unable to access it.
