it returns current h2 element, when trying innerhtml or innertext return null. doing wrong?
getelementsbytagname returns nodelist, not element. list doesn't have innerhtml, each of elements does, e.g.:
var list = this.getelementsbytagname('h2'); if (list[0]) { title = list[0].innerhtml; } or if you're sure exist:
title = this.getelementsbytagname('h2')[0].innerhtml; ...but throw exception if there no h2's found.
