<form action="" method="POST">
<input type="submit" onclick="hide_group_posts();">
</form>

<div id='div_i_want_to_hide'>
<?php include $_SERVER['DOCUMENT_ROOT']."page.php";?>

}
</script>

Answer 1

$('form').submit(function(){
    $('#div_i_want_to_hide').hide();  
});

If it didn't help you, one of the following must be true:

• You didn't reference the jQuery library.
• You didn't wrap the code with the DOM ready event.
• You got typos.
• The submit function worked, and you got new page, because you didn't prevent the default.

Prevent it like this:

$('form').submit(function(e){
    $('#div_i_want_to_hide').hide();  
    e.preventDefault();
    // Or with: return false;        
});
