[Solved]Fix the error!

Question

https://code.sololearn.com/W4P11jq7g128/?ref=app
I have figured out that SL JS gets loaded before the HTML part and added an onload function to overcome that but couldn't resolve the new errors when I put my all js inside the function .

What did I do wrong ? 🤔

Answer 1

I believe the compiler automatically adds it if you don't declare it as a way to be lenient on syntax. If you're developing for all browsers you probably don't want to rely on that

Answer 2

This is the only part you need in the onload funtion window.onload=function(){
ele = document.getElementById("res");
}

Answer 3

You need to declare it globally. Your current error is due to everything inside onload being function scoped to function().

Answer 4

JME I see. That fixs everything .

Answer 5

It all works for me

Answer 6

JME Try now

Answer 7

Try to use addEventListener instead of onclick function, I too faced this problem.
I have corrected one, remaining do yourself
