问题
I have a PDF in an iframe, for example:
<iframe src="https://www.irs.gov/pub/irs-pdf/f1040.pdf"></iframe>
In Chrome (at least), clicking the link in the bottom left corner of the PDF causes the parent (containing) frame to navigate to http://www.irs.gov/form1040.
Is there way to make this link to open in a new tab instead?
