我首次看到 debounce 的 JavaScript 实现是在 2009 年的 John Hann 的博文。不久后,Ben Alman 做了个 jQuery 插件(不再维护),一年后 Jeremy Ashkenas 把它加入了 underscore.js。而后加入了 Lodash 。 一、throttle和debounce区别: throttle和debounce的作用就...
JS-Debouncing-Throttling 防抖动(Debouncing)和节流阀(Throttling) 防抖(Debounce)和节流(throttle)都是用来控制某个函数在一定时间内执行多少次的技巧,两者相似而又不同。 当我们给 DOM 绑定事件的时候,加了防抖和节流的函数变得特别有用。为什么呢?因为我们在事件和函数执行之间加了一个控制层。记住,我们是无法控制...
The first time I saw debounce implemented in JavaScript was in 2009 inthis John Hann post(who also coined the term). Soon after that, Ben Alman createda jQuery plugin(no longer maintained), and a year after, Jeremy Ashkenasadded it to underscore.js. It was later added to Lodash, a drop...
