getting a url address of (a href javascript:; onclick= )

on automatic crawling using selenium the original url i started with is http://law.go.kr/precSc.do?tabMenuId=tab67 and @Sers got http://law.go.kr/precScListR.do?q=*&section=evtNm&outmax=50&pg=1&fsort=21,10,30&precSeq=0&dtlYn=N

i want to know how Sers got this url out of this website. since im trying to crawl for 2 more website. 1.https://casenote.kr/search/?q=%EA%B5%90%ED%86%B5%EC%82%AC%EA%B3%A0 2.https://glaw.scourt.go.kr/wsjo/panre/sjo050.do#1550754154586
