指令通知应在5秒后删除“本身”。但是有些元素会被遗漏,有些元素会被删除多次。标识符属性对于每个通知都是唯一的。谢谢你的帮助。
厂
angular.module('AdS').factory('notificationFactory', function () {
var notificationFactory = {};
notificationFactory.notifications = [];
notificationFactory.identifier =0;
notificationFactory.add = function(note){
if(typeof note!=='undefined'){
notificationFactory.identifier++;
note.identifier = notificationFactory.identifier;
notificationFactory.notifications.push(note);
}
}
notificationFactory.delete = function (note) {
if(typeof note!=='undefined'){
for(var i =0;i<notificationFactory.notifications.length;i++){
if(notificationFactory.notifications[i].identifier==note.identifier){
notificationFactory.notifications.splice(i,1);
}
}
}
return "";
}
notificationFactory.getNotifications = function () {
return notificationFactory.notifications;
}
return notificationFactory;
});
指令
angular.module('AdS').directive('siteNotification', [
'$timeout',
function ($timeout) {
return {
restric: "E",
templateUrl: "/Templates/htmlBits/notification.html",
scope: {
note:"=",
center:"="
},
link: function (scope, element, attrs) {
$timeout(function () {
scope.center.delete(scope.note);
}, 5000);
scope.delete=function(note){
scope.center.delete(note);
}
}
};
}
]);
HTML
<site-notification ng-repeat="not in notificationCenter.notifications track by $index" center=notificationCenter note=not ></site-notification>

不是使用notificationFactory.notifications
数组,而是使用一个对象,唯一标识符指向您的注释,如下所示:
notificationFactory.notifications = {};
notificationFactory.add = function(note) {
if (typeof note!=='undefined') {
notificationFactory.identifier++;
notificationFactory.notifications[notificationFactory.identifier] = note;
}
}
notificationFactory.delete = function (note) {
if(typeof note!=='undefined'){
notificationFactory.notifications[notificationFactory.identifier] = null;
}
return "";
}
另外,在你的指令中,你似乎是通过html注入notificationFactory。这是非常不寻常的,注入工厂的典型方法如下:
angular.module('AdS').directive('siteNotification', [
'$timeout',
'notificationFactory',
function ($timeout, notificationFactory) {
...
}
我能看到以不同方式做到这一点的唯一原因是,如果您希望能够在指令中注入不同类型的工厂。
