window.alert("before sleep ..."); sleep(2000); window.alert("after sleep ..."); 1. 2. 3. 4. 5. 6. 7. 缺点不用多说,只有IE支持(IE7因为安全限制也而不能达到目的)。 除上之外,还有利用Applet或者调用Windows Script Host的WScript.Sleep()等等鬼点子,这些都是万不得已的权宜之计。 终于有...
getTime(); for (var i = 0; i < 1e7; i++) { if ((new Date().getTime() - start) > milliseconds){ break; } } } Usage Sleep for 1 second (1000 milliseconds): console.log(new Date()); console.log('Dude!'); sleep(1000); console.log(new Date()); Result in Firebug's ...

2. 方法二:同步函数,使用whlie(){}或者for实现死循环;缺点是cpu占用率很高; 原理: 执行死循环,阻塞后续程序的执行,进而实现休眠的假象。 2.1.while代码实现: // 函数实现,参数 delay 单位 毫秒 ;functionsleep(delay){varstart=(newDate()).getTime();while((newDate()).getTime()-start<delay){// 使用...
sleep(); //sleep some time to release the CPU do other stuff } } 通过事件驱动机制,我们可以想象Javascript的编程模型就是响应一系列的事件,执行对应的回调函数。很多UI框架都采用这样的模型(例如Java Swing)。 那为什要异步呢,同步不是很好么? 异步的主要目的是处理非阻塞,在和HTML交互的过程中,会需要一些...
cd /d C:\Users\%username%\Desktop\server\node && npm install sleep --save 使用方法: var sleep = require( 'sleep' ); sleep.sleep(n): sleep for n seconds sleep.msleep(n): sleep for n miliseconds sleep.usleep(n): sleep for n microseconds (1 second is 1000000 microseconds) ...
function mySleepFunction(delayTime) { return new Promise(resolve => setTimeout(resolve, delayTime)); } async function myDelayedFunction() { document.write('Javascript Sleep Functionality Execution'); for (let counter = 1; counter <11 ; counter++) { ...
使用时只需要“await sleep(毫秒)”即可，它可以阻塞当前函数的后续执行，也可以用到for循环中，并且不...
What is sleep() in JavaScript? A sleep() function is used to pause the execution of a program for a certain amount of time. JavaScript does not have a built-in sleep() function, but using the setTimeout() method in JavaScript can achieve the same goal to delay code execution. ...
