Try finding the exact line that is breaking. 尝试找到破碎的确切线。 When safari is set Always block cookies and other website data then it breaks local storage, and several of the image manipulation APIs. 当设置safari时，始终阻止cookie和其他网站数据，然后它会破坏本地存储和几个图像处理API。 You might try to determine exactly which line is failing, and wrap that line in a try/catch. 您可能会尝试确定哪条线路出现故障，并将该线路包装在try / catch中。
