Event handler

Question

I am having problems using events in javasript.....Can sololearn support events in javascript???

Answer 1

Yes sololearn supports event

Sololearn compiles web code by putting scripts in JS tab in the head of html. Therefore all getElementById or similar attempt will return null because the element doesn't exist yet.
