Throttle guarantees a constant flow of events at a given time interval, whereas debounce groups a flurry of events into one single event.
Some of goals of this project worth noting include: Be lightweight, flexible and easy to use; Only bind scroll event handler one time; Throttle scroll events; #Usage ngScroll is composed of one factory and one directive.
CommonSenseCode. If nothing happens, download the GitHub extension for Visual Studio and try again.
A better option would be to provide plugins for the renderer that deal with // Add the grid to the event arguments if it's not there. This issue has been automatically locked due to inactivity. 'queues a final event if trailing param is truthy'. //... Imo it should be done on a lower-level. Memoize & Cache expensive functions
For example, if you were using underscore: However, in ES6 / TypeScript, the class syntax does not have a way to define a method based on the output of some function like this.
UI Grid: an Angular Data Grid. The directive approach is similar to default angular directives. You signed in with another tab or window. // Default time to throttle scroll events to. // Add the grid to the event arguments if it's not there. This action has been performed automatically by a bot. 'queues a final event if trailing param is truthy'. Some of goals of this project worth noting include: #Usage
http://reactivex.io/documentation/operators/debounce.html, http://blog.thoughtram.io/angular/2016/01/06/taking-advantage-of-observables-in-angular2.html, [feature] Enable/disable event listening on @HostListeners, https://manuel-rauber.com/2015/12/31/debouncing-angular-2-input-component/, https://github.com/baio/link-shortener/blob/master/src/app/utils/debounce-decorator.ts, Avoid triggering change detection unless necessary, Text entry into md-input (for auto-resizing a, Window resize events for several components (such as drawing ticks for a slider), Scrolling events for things (headers, etc) that are "stickied", For parent components doing something based on the addition or removal of a child (such as a re-layout). If you have an event that gets fired frequently like an input change event or a scroll event, its better to debounce or throttle the event listener depending on the use-case to avoid running logic many times per frame affecting the FPS and performance of your app.
If nothing happens, download GitHub Desktop and try again. Angular module for handling scroll events in your angular js applications. Utility library underscopre (lodash) function throttle can be used for this purpose. this (based on the event name, independent of the current component). Not to mention that this doesn't work for Dart at all. Also | is already used for pipe syntax so it can't be reused here. You can still use the ES5 syntax, but that totally kills the hip vibe. By reversing the order, I think it's now aligns better with @mhevery's concern (and that I also share).

My 2cents on this subject. UI Grid: an Angular Data Grid. }, @debounce(300) That already has a debounce operator http://reactivex.io/documentation/operators/debounce.html. Something worth noting is that when the scroll event is triggered, the expression is not wrapped in $apply(). download the GitHub extension for Visual Studio, Amount of time that has passed since the last scroll event, How far we have traveled along the X axis since the last scroll, How far we have traveled along the Y axis since the last scroll, Velocity of the scroll along X axis (distance / time), Velocity of the scroll along Y axis (distance / time), Direction we are travelling along the X axis (left or right), Direction we are travelling along the Y axis (up or down).

I am still in the phase of throwing ideas out, and getting feedback. Infinite Scrolling the Angular 6 and RxJS Way! * var throttledFunc = gridUtil.throttle(function(){console.log('throttled');}, 500, {trailing: true}); * throttledFunc(); //=> queues attempt to log throttled for ~500ms (since trailing param is truthy). onMouseMove: Function, constructor() {
* throttledFunc(); //=> updates arguments to keep most-recent request, but does not do anything else. That way we could short circuit the marshaling between the App and UI side. this.onMouseMove = this.checkHoverPosition; One way to think about it is throttle is time-based and debounce is event driven. Also, it's not clear how it relates to zones. This is a feature that is needed quite often. Because if it is, it will be all the more difficult for the browser to keep up.
