我在尝试导入PDF中的一些国旗时遇到了相同的问题。在chrome和firefox中一切正常，但在尝试使用IE11在PDF中导入相同的标志时出现问题。我有一个带有国旗图标的类国旗图标，它转换成本地服务器上svg的背景图像url。

检查这一个，可能是浏览器问题……我检查了上面的链接，但我应该怎么解决这个问题？它在其他浏览器中也能很好地工作，ie必须遵循哪种方法？这就是问题所在，伙计，你必须等到有人解决这个问题，Internet Explorer一直是web开发人员头疼的问题，什么都做不了。检查这一个，可能是它的浏览器问题…我检查了上面的链接，但我应该做什么来解决这个问题？它在其他浏览器中也能很好地工作，ie必须遵循哪种方法？这就是问题所在，伙计，你必须等到有人解决这个问题，Internet Explorer一直是web开发人员头疼的问题，什么都做不了。
