在tiktok ads中，创建了新的pixel（Events API ），但是由于没有数据，后台不会显示（有数据显示active），导致在创建campaigns 的时候，无法选择新创建的pixel和event。解决方法：

<body>
<script>
    !function (w, d, t) {
        w.TiktokAnalyticsObject = t;
        var ttq = w[t] = w[t] || [];
        ttq.methods = ["page", "track", "identify", "instances", "debug", "on", "off", "once", "ready", "alias", "group", "enableCookie", "disableCookie"], ttq.setAndDefer = function (t, e) {
            t[e] = function () {
                t.push([e].concat(Array.prototype.slice.call(arguments, 0)))
            }
        };
        for (var i = 0; i < ttq.methods.length; i++) ttq.setAndDefer(ttq, ttq.methods[i]);
        ttq.instance = function (t) {
            for (var e = ttq._i[t] || [], n = 0; n < ttq.methods.length; n++) ttq.setAndDefer(e, ttq.methods[n]);
            return e
        }, ttq.load = function (e, n) {
            var i = "https://analytics.tiktok.com/i18n/pixel/events.js";
            ttq._i = ttq._i || {}, ttq._i[e] = [], ttq._i[e]._u = i, ttq._t = ttq._t || {}, ttq._t[e] = +new Date, ttq._o = ttq._o || {}, ttq._o[e] = n || {};
            var o = document.createElement("script");
            o.type = "text/javascript", o.async = !0, o.src = i + "?sdkid=" + e + "&lib=" + t;
            var a = document.getElementsByTagName("script")[0];
            a.parentNode.insertBefore(o, a)
        };
        ttq.load('REPLACE_ME');
        ttq.track("CompletePayment");
        ttq.track("ViewContent");
        ttq.track("SubmitForm");
        ttq.track("AddPaymentInfo");
        ttq.track("AddToCart");
        ttq.track("AddToWishlist");
        ttq.track("ClickButton");
        ttq.track("CompleteRegistration");
        ttq.track("Contact");
        ttq.track("Download");
        ttq.track("InitiateCheckout");
        ttq.track("PlaceAnOrder");
        ttq.track("Search");
        ttq.track("Subscribe");
    }(window, document, 'ttq');
</script>
</body>

将以上的代码保存到一个html文件，替换你自己的pixel ID，然后在浏览器打开，刷新几次，等几分钟就可以在后台看到pixel显示为活动了。
