i am writing an offline web application.
i have a manifest files for my applicationCache. and i have handlers for appCache events. i want to detect if the files being downloaded are being downloaded for the first time or being updated. because in case they are being updated, i would like prevent my application code from running, since i will refresh the browser after updating my app.
my specific problem here is that when the "checking" events gets fired, the applicationCache status is already "DOWNLOADING",
does anybody know how to get the applicationCache.status before any manifest or files gets downloaded?
thanks in advance for any answer
window.applicationCache.addEventListener('checking', function (event) {
console.log("Checking for updates.");
console.log("inside checking event, appcache status : %s", applicationCache.status);
}, false);
window.applicationCache.addEventListener('updateready', function (e) {
if (window.applicationCache.status == window.applicationCache.UPDATEREADY) {
// Browser downloaded a new version of manifest files
window.location.reload();
}
}, false);
window.applicationCache.addEventListener('downloading', function (event) {
appCommon.information("New version available", "Updating application files...", null, null);
}, false);
window.applicationCache.addEventListener('progress', function (event) {
$("#informationModal").find(".modal-body").html("Updating application files... " + event.loaded.toString() + " of " + event.total.toString());
}, false);
window.applicationCache.addEventListener('cached', function (event) {
$("#informationModal").find(".modal-body").html("Application up to date.");
setTimeout(function () { $("#informationModal").find(".close").click(); }, 1000);
}, false);
