示例代码：
var $input = $('#input'), $results = $('#results'); /* Only get the value from each key up */ var keyups = Rx.Observable.fromEvent(input, 'keyup') .map(function (e) { return e.target.value; }) .filter(function (text) { return text.length > 2; }); /* Now throttle/debounce the input for 500ms */ var throttled = keyups .throttle(500 /* ms */); /* Now get only distinct values, so we eliminate the arrows and other control characters */ var distinct = keyups .distinctUntilChanged();
