Javascript 幻影移除类

我使用Pagers cli（phantomjs）从网站上截图

拍摄屏幕截图时，动画内容不起作用。在呈现页面之前，我尝试从HTML中删除类。（“.wow、.fadeIn、.animated…”

我可以删除元素等，因此我在代码的正确位置，但下面的特定代码不起作用

page.evaluate(function (css) {      
    [...]
    Array.prototype.slice.call(document.getElementsByClassName("wow")).forEach(function(script) {
        script.classList.remove("wow");
    });
}, opts.css);

HTML:

劳作
Hol-und Bringservice
移动服务
代萨茨瓦根
松嫩舒茨福林酒店
克里曼拉根服务
Autoglasversiegelung
迪奇基茨普吕冯
功能测试

您如何确认它不起作用？您是否尝试过对检查代码是否“工作”的代码进行“异步化”？如何验证它是否工作？您是否尝试过对检查代码是否“工作”的代码进行“异步化”？
