can not get link

[Xuetubuxue]

In the PDF, there is a link attribute that runs a JavaScript script when released. However, I cannot obtain the links in the page using get_links. Why is this?

These boxes appear after I click the links, but they are not visible initially. Clicking will bring up the component properties.
javascript：var cmd = app.popUpMenu( "INS62402782 : XU1" , "-" , "Name=INS62402782" , "ID=1385489" , "Reference=XU1"）

Without the file that question cannot be answered.
