由 ≡放荡痞女 提交于 2019-12-11 07:53:31

问题 This question is specific to pdf.js, a javascript based pdf renderer. I'm building a custom version where I need to extract the text that I select inside the pdf.

This method returns a specific Selection

How can I use a vendor libary (specifically I want to use PDF.js) in a Vue component?
