[英]How to clear the sessionstorage on browser refresh , but this should not clear on click of browser back button
我只想在頁面刷新時清除 session 存儲,而不是在瀏覽器后退按鈕單擊或向前單擊時想使用 angularjs/javascript 來實現
我在單擊后退按鈕時將數據保存在會話存儲中,所以我只想在單擊瀏覽器刷新按鈕時清除相同的數據,但它不應該清除后退
我努力了
if (performance.navigation.type == 1) {
$window.sessionStorage.clear();
// clearing the sessionstorage data
}
// but this one is clearing after clicking 2 times on refresh button
if (performance.navigation.type == 0) {
$window.sessionStorage.clear();
// clearing the sessionstorage data
}
// this one is clearing for back button as well ,
// tried onbeforeunload, onpopstate as well its not working its clearing for back button too
// please let me know how to implement this one, thanks in advance
// no jquery please
是的,您可以在Windows加載上實現此功能,然后清除會話存儲或刪除密鑰
$window.location.reload();
sessionStorage.clear();
要么
// Remove saved data from sessionStorage
$window.location.reload();
sessionStorage.removeItem('key');
保留設置sessionStorage的頁面地址,然后在onload事件上檢查它。 如果它們相同,則刪除sessionStorage內容。
window.onbeforeunload = function(){
sessionStorage.setItem("origin", window.location.href);
}
然后在onload事件中:
window.onload = function(){
if(window.location.href == sessionStorage.getItem("origin")){
sessionStorage.clear();
}
}
嘗試使用$stateChangeStart
事件
$rootScope.$on('$stateChangeStart', function(event, toState, fromState){
if(toState.name === fromState.name){
$window.sessionStorage.clear();
}
})
希望這會有所幫助!!
你可以使用 beforeunload
window.addEventListener("beforeunload", function(e) {
sessionStorage.removeItem("{session}");
});
或者設置為 null
window.addEventListener("beforeunload", function(e) {
sessionStorage.setItem("{session}",null);
});
