runAnimation: function(){
var iframe = document.querySelector('.active iframe');
window.frames[iframe.id].contentWindow.runAnimation();
},
以上代码在Safari中打印以下错误：
TypeError: undefined is not an object (evaluating 'window.frames[iframe.id].contentWindow.runAnimation')
我已经尝试了答案here，here和here，基本上是每个可能的解决方案。
另一个有趣的事情是窗口仅在Safari上返回未定义！

答案 0 :(得分：0)
我尝试过这样似乎有效
var iframe = document.querySelector('.container iframe');
window.frames[iframe.id].contentWindow.runAnimation();
