How to copy PCFU field value into a text field

[Arunajyothi Samala]

Hi,

we have a PCFU field which has a hyperlink of issue key, looking for a solution to extract value from the hyperlink as a text and copy into a text field within the same project.

eg. PCFU field named "parent capaility" has a drop down value of issue keys with hyperlink, the other field named "parent capability link" should have the above selected issue key with normal text .
