跟随深色模式切换

[eallion]

当 DisqusJS 加载完以后，切换网站的深色（或浅色）样式，评论样式不能跟随适配。我发现我也提过这样的 Issue，现在解决了，分享一下。每个网站切换深色模式的方法不一样，所以感觉不太适合提 PR。

1. 监听样式切换事件

let event = new Event('themeChanged');
document.dispatchEvent(event);

2. 重载 DisqusJS

<script>
    var disqus_config = function () {
        this.page.url = ' '; // Replace PAGE_URL with your page's canonical URL variable
        this.page.identifier = ' '; // Replace PAGE_IDENTIFIER with your page's unique identifier variable
    };

    (function () {
        var d = document,
            s = d.createElement('script');
        s.src = 'https://eallion.disqus.com/embed.js'; // Replace SITE_URL with your site's URL
        s.setAttribute('data-timestamp', +new Date());
        (d.head || d.body).appendChild(s);
    })();

    // Disqus theme switching
    document.addEventListener('themeChanged', function (e) {
        if (document.readyState == 'complete') {
            DISQUS.reset({
                reload: true,
                config: disqus_config
            });
        }
    });
</script>
