当标签不可见时，jQuery进度栏会暂停

Question

1＆1实现了每封电子邮件之间10秒钟的垃圾邮件减少时间间隔，因此这次我使用了jquery进度栏进行填充，然后重新加载页面以发送下一封电子邮件。

但是，当选项卡不可见时，进度条将停止并且不会继续。无论选项卡不可见，如何强制它运行？

function move() {
	var elem = document.getElementById("myBar"); 
	var width = 1;
	var id = setInterval(frame, 100);
	function frame() {
		if (width >= 100) {
			clearInterval(id);
			window.location.href = "{$nextpage}"
		} else {
			width++; 
			elem.style.width = width + '%'; 
		}
	}
}
$(document).ready(move());
