我试图在页面刷新时从sessionStorage检索我的搜索和过滤数据.
sessionStorage.restorestate返回undefined,有谁知道为什么？
app.run(function($rootScope) {
$rootScope.$on("$routeChangeStart",function(event,next,current) {
if (sessionStorage.restorestate == "true") {
$rootScope.$broadcast('restorestate'); //let everything know we need to restore state
sessionStorage.restorestate = false;
}
});
//let everthing know that we need to save state now.
window.onbeforeunload = function(event) {
$rootScope.$broadcast('savestate');
};
});
在Angular应用程序中刷新页面时,就像完全重新启动应用程序一样.因此,要从会话存储中恢复,只需在服务工厂执行时执行此操作.
原文链接：https://www.f2er.com/angularjs/142321.htmlapp.factory('CustomerSearchService',['$rootScope',function($rootScope) {
...
function restoreState() {
service.state = angular.fromJson(sessionStorage.CustomerSearchService);
}
if (sessionStorage.CustomerSearchService) restoreState();
...
}
]);
保存部分已经正确了.
app.factory('CustomerSearchService',function($rootScope) {
...
function saveState() {
sessionStorage.CustomerSearchService = angular.toJson(service.state);
}
$rootScope.$on("savestate",saveState);
...
}
]);
app.run(function($rootScope) {
window.onbeforeunload = function(event) {
$rootScope.$broadcast('savestate');
};
});
