JavaScript版本sleep()为“ await”。等待功能会暂停当前的aync功能。
您可以尝试运行以下代码以在JavaScript中实现睡眠
<!DOCTYPE html>
<html>
<body>
<script>
function setSleep(ms) {
return new Promise(resolve => setTimeout(resolve, ms));
}
async function Display() {
document.write('Wait for 5 seconds!');
await setSleep(5000);
document.write('After 5 seconds!');
}
Display();
</script>
</body>
</html>
