在 Rxjs5 中找不到 Rx.Observable.pairs,我只需将对象转换为 Observable 并检查每个属性的更改。有任何想法吗?
var a = { aa: "aa", bb: "bb" };
function pairs(obj) {
// List of object's key-value pairs
var keyValuePairs = Object.keys(obj).map(key => ({ key, value: obj[key] }));
// Convert to an Observable and return
return Rx.Observable.from(keyValuePairs);
}
var xxx = pairs(a);
xxx.subscribe(x => {
console.log(x);
})
a.aa = "mm";
