I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...
Try setting the session timeout to 10 minutes.
ReplyDeleteini_set('session.gc_maxlifetime',10);
session_start();
ReplyDelete// 10 mins in seconds
$inactive = 600;
$session_life = time() - $_session['timeout'];
if($session_life > $inactive)
{ session_destroy(); header("Location: logoutpage.php"); }
S_session['timeout']=time();
The code above was taken from this particular page.
compare timestamps between two requests, one from the current request, one stored in the session.
