You can use pageshow
event to handle situation when browser navigates to your page through history traversal:
window.addEventListener( "pageshow", function ( event ) {
var historyTraversal = event.persisted ||
( typeof window.performance != "undefined" &&
window.performance.navigation.type === 2 );
if ( historyTraversal ) {
// Handle page restore.
window.location.reload();
}
});
Note that HTTP cache may be involved too. You need to set proper cache related HTTP headers on server to cache only those resources that need to be cached. You can also do forced reload to instuct browser to ignore HTTP cache: window.location.reload( true )
. But I don’t think that it is best solution.
