Not sure how to fox this issue in iFrames

Var parser = new DOMParser;

推荐答案
您需要记住，当您打开< iframe>时在您的页面上，对于大多数用途，它与常规页面位于不同的位置。因此，根据您调用DOM访问功能的位置，您需要记住它只会查看它自己的页面 - 也就是说，它是自己的范围。
例如，您可以在其内部打开页面的副本。然后它将在父页面和子页面中具有相同的id =''值。 DOM可以区分它们，因为它们处于不同的范围。
注意在'parent'和'child'的前一段中的使用。有能力在一个范围内，并使用对父母或孩子的引用访问另一个范围。
所以 - 取决于您请求数据的位置相对于它的位置是的，你会看到不同的结果（如失败）。考虑一下 - 你可以解决你的问题。
You need to keep in mind that when you open an <iframe> on your page it is, for most purposes, a separate location from your regular page. Thus, depending upon where you call your DOM accessing functionality, you need to keep in mind that it will only look at it's own page - that is, it's own scope.
As an example, you may open a copy of a page inside of itself. It would then have the same id='' values in both the parent and child pages. The DOM can tell them apart because they are in "different scopes".
Note the use in the previous paragraph of 'parent' and 'child'. There is the ability to be in one scope and access the other using references to the parent or child.
So - depending upon where you request the data relative to where it is, you will see different results (like failure). Consider this - you may solve your problem.
