373 PointsI need help understanding use querySelectorAll to obtain a reference to all elements in a document with the class --?
I'm stumped and have watched the video over several times and reviewed my notes. What is this asking? I've tried the same methods they used in the video and none of them have worked.
How would you use querySelectorAll to obtain a reference to all elements in a document with the class student-info and assign it to the constant studentInfo?
const studentInfo = ___________

const studentInfo = document.querySelectorAll(".student-info");

12,350 Pointsit doesn't seem to like single quotes like this: document.querySelectorAll('.student-info'); it will only accept document.querySelectorAll(".student-info");

14,705 PointsI had the same issue. I followed exactly what Guil did in the video:
const studentInfo = document.querySelectorAll('student-info');
and it didn't pass, but the answer from @stevenparker worked just fine. Anyone know why this is the case?
Brooke Smart

17,417 PointsIt’s because you used single quotes instead of double quotes also .
Mike Hatch

6,905 PointsI've tried both const studentInfo = document. querySelectorAll(".student-info"); const studentInfo = document. querySelectorAll('.student-info');
neither are passing today.
