Basic Ajax Cache Issue
- by michaelespinosa
I have a single page that I need to on occasion asynchronously check the server to see if the status of the page is current (basically, Live or Offline). You will see I have a function with a var live that is set when the page initially loads. I then do an ajax request to the server to retrieve whether the status of live is true or false. I compare the initial live variable with the newly returned data json object. If they're the same I do nothing, but if there different I apply some css classes. I recursively run it with setTimeout (Is there a better way to recursively do this?).
My Problem:
data.live doesn't change from it's initial time it runs even when it has changed in the db. I know my mysql is working because it returs the right value on the initial load. It seems like a caching issue.
Any help is greatly appreciated.
function checkLive() {
var live = <?=$result["live"]?>;
$.ajax({
type: 'get',
url: '/live/live.php',
dataType: 'json',
success: function(data) {
console.log('checking for updates... current:' + data.live);
if (data.live == live) {
return;
} else {
var elems = $('div.player_meta, object, h3.offline_message');
if (data.live == '1') {
elems.removeClass('offline').addClass('live');
} else {
elems.addClass('live').addClass('offline');
}
}
}
});
setTimeout(function() { checkLive() } ,15000);
}
checkLive();
