示例1: it
it('delays change notifications until disabled', (done) => {
const prop = new ReactiveValueProperty(testOwner, 0);
const subject = new BehaviorSubject<number>(0);
prop.changed
.map(x => x.value)
.subscribe(subject);
subject.value.should.eql(0);
prop.value = 1;
subject.value.should.eql(1);
subject
.subscribe(x => {
if (x === 3) {
done();
}
});
Observable.using(
() => prop.delayChangeNotifications(),
x => {
prop.value = 2;
subject.value.should.eql(1);
prop.value = 3;
subject.value.should.eql(1);
x.unsubscribe();
}
).subscribe();
});示例2:
sub1 => {
prop.value = 2;
