js实现页面title闪烁

在页面收到消息之后需要通过titile闪烁的方式来提示用户，可以通过js来实现

class MessageNotice {
    timer = undefined;
    title = document.title;
    count = 0;

    show() {
        this.timer = setInterval(() => {
            // 偶数显示提示
            if (this.count % 2 === 0) {
                document.title = "【新消息】" + this.title;
            } else {
                document.title = "【  】" + this.title;
            }
            this.count++;
        }, 500)
    }

    stop() {
        if (this.timer) {
            clearInterval(this.timer );
            this.timer = null;
            this.count = 0;
            document.title = this.title;
        }
    }
}

const messageNotice = new MessageNotice();
// 开始执行
messageNotice.show();

// 停止
//messageNotice.stop();
