本文实例讲述了JavaScript自定义等待wait函数用法。分享给大家供大家参考。具体分析如下: 下面是一个js自定义的wait函数,可以暂停程序的执行 function sleep(delay) { var start = new Date().getTime(); while (new Date().getTime() < start + delay); } //usage //wait for 3 seconds sleep(3000); ...
具体分析如下：下⾯是⼀个js⾃定义的wait函数，可以暂停程序的执⾏ function sleep(delay){ var start = new Date().getTime();while (new Date().getTime() < start + delay);} //usage //wait for 3 seconds sleep(3000);希望本⽂所述对⼤家的javascript程序设计有所帮助。
awaitdelay(3000);console.log('Thisisprintedafter3seconds');console.log('End');} example();在上述示例中，`delay`函数返回一个在指定时间后resolved的Promise，然后 在`example`函数中使用`await`来等待这个Promise的状态变更。这些都是JavaScript中常见的等待操作的用法。根据具体的需求和场景选择适合的方法来...

The below javascript example will add a hard wait of 3 sec. await page.waitForTimeout(3000); // Waits for 3 seconds 2. page.waitForSelector() It enables scripts to wait for an element with a matching selector to be visible. This is a preferred method for waiting, as it ensures that...
consts=newDate().getSeconds();setTimeout(function(){// 输出 "2",表示回调函数并没有在 500 毫秒之后立即执行console.log("Ran after "+(newDate().getSeconds()-s)+" seconds");},500);while(true){if(newDate().getSeconds()-s>=2){console.log("Good, looped for 2 seconds");break;}}...
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) 代码实现: 使用方法: // 参数单位为: 秒数 ; function wait(haomiao) { // 将毫秒参数,转换为 秒...

Now, let’s wait 5 seconds in JavaScript. To illustrate the wait effect, we will run other functions after the setTimeout code. jsx function multiply(arg1, arg2) { return arg1 * arg2; } function greetUser(user) { return `Welcome back, ${user}. Hope that coffee break was great?`;...
