function debounce(func, delay = 1000) { let timeoutId return function(...arguments) { console.log("function called") clearTimeout(timeoutId) timeoutId = setTimeout(() => { func(...arguments) }, delay) } } function doSomething() { console.log("I am doing something") } const deb...
Here's an illustration to explain the approach to debouncing a function: This approach reduces how many times the function is called within intervals of typing in an input. Now, let's see this in code. functiondebounce(func,delay=1000){lettimeoutIdreturnfunction(...arguments){console.log("...
log("This function is being executed after a delay"); } // 延迟执行函数,延迟时间为2000毫秒(即2秒) setTimeout(delayedFunction, 2000); 复制代码 在上面的例子中,我们定义了一个名为delayedFunction的函数,然后使用setTimeout函数来延迟执行这个函数,延迟时间为2000毫秒(即2秒)。当延迟时间到达后,delayedF...
Bingo,一点没错!如果你在一个应用里面常常要“延时执行某某函数”,那末基于DRY的原则,可以针对Function全局对象进行扩展,为函数增加一个延时方法如delay,这样会让你的代码更简洁有效。 扩站Function对象增加delay方法如下: 代码 Function.prototype.delay=function(this1,timeout){ this1=this1||null; timeout=timeo...
将DOM元素按一定频率移动即可获得动画,在视频领域,这个频率被称为帧速率,单位为帧每秒fps(frame per second) 单次执行为:.setTimeout(action, delay);多次执行:setInterval(action,delay) function hide(elementId) { document.getElementById(elementId).style.display = 'none'; } window.onload = function()...

function sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } console.log('Hello'); sleep(2000).then(() => { console.log('World!'); }); 运行这段代码,你会在控制台看到 “Hello”。然后,在短暂的两秒钟后,“World!”v会接着出现。这是一种既简洁又有效的引入延迟的方...

//使用方法setTimeout(callback,delay);setInterval(callback,delay);functioncallback(){console.log('rainbow'); }vardelay =1*1000;//解释一下callback:定时器要执行的方法 delay:定时器执行方法的间隔。单位ms毫秒 setTimeout、setInterval区别 setTimeout 只能执行一次,而setInterval一直执行。
// 防抖 function debounce(func, delay) { let timer; return function() { clearTimeout(timer); timer = setTimeout(func, delay); } } // 节流 function throttle(func, delay) { let timer = null; return function() { if (!timer) { timer = setTimeout(function() { func(); timer = ...
