在JavaScript中,要在迭代之间应用延迟(例如,延迟一段时间后再执行下一个迭代),可以使用async/await和Promise结合setTimeout函数来实现。以下是一个示例: 代码语言:javascript 复制 asyncfunctiondelayForLoop(array,delay){for(constitemofarray){console.log(item);awaitnewPromise(resolve=>setTimeout(resolve,delay))...
著名的 setTimeout 无需进一步解释。setTimeout 的第一印象是异步执行可以延迟,我们经常这样实现:setTimeout(() => { console.log(‘Delay 3 seconds’);},3000)当 setTimeout 用得越来越多时,问题也出现了。有时函数会在 3 秒的书面延迟后 5 或 6 秒内执行。怎么了?让我们从一个例子开始:setTime...
In the for-loop, we will use getNumFruit to get the number of each fruit. We’ll also log the number into the console.Since getNumFruit returns a promise, we can await the resolved value before logging it.const forLoop = async _ => { console.log('Start') for (let index = 0; ...

Delay JavaScript Loading Putting your scripts at the bottom of the page body lets the browser load the page first. While a script is downloading, the browser will not start any other downloads. In addition all parsing and rendering activity might be blocked. ...
Take a second to consider what might happen in the above code snippet. Itwon’tprint the numbers 0 to 4 with a delay of one second between each. ather, the numbers 0 to 4 will be logged to the console simultaneously after a delay of one second. Why? Because the loop doesn’t pause...
在上面的示例中,我们定义了一个名为delayedWhileLoop的函数,它接受三个参数:condition(条件函数)、action(执行函数)和delay(延迟时间)。函数首先检查条件函数的返回值,如果为真,则执行执行函数,并在延迟时间后再次调用delayedWhileLoop函数。这样就实现了延迟执行While循环的效果。 需要注意的是,使用延迟执行While循环时...
setTimeout()delay之后还可以带参数param1,param2,……,所以理论上(为什么是“理论上”?因为老版IE又不支持,艹)我们还可以这样: 1functionshowEvent(event){2setTimeout(3function(event){//把event作为参数传入4alert('in setTimeout:'+event);5}, 100, event//event作为匿名回调函数的参数6);7} ...
clearTimeout和clearInterval这两种方法采取从上面函数返回一个整数标识符setTimeout和setInterval例:setTimeoutalert("before setTimeout");setTimeout(function(){ alert("I am setTimeout"); },1000); //delay is in milliseconds alert("after ...
