[SOLVED]"document.body.getElementById()" does not work in SoloLearn?(Mobile)

I have been trying to use the function mentioned in the title but it does not work even though I was able to use that function before. https://code.sololearn.com/WQo9nDOBa2b4/?ref=app This code has same function that I am too lazy to write it here again and it does not work. removing ".body" makes it go totally crazy too.

Yoi have to know that content of js tab on SL is injected like an inline script inside <head> tag of final html (that your browser render) than any call that get a dom element reference (like getElementById) return null because not dom is loaded yet... You have to call they AFTER dom is loaded then on window.onload callback or inside a DOMContentLoaded listener or put they in a function then call it from an inline script placed at bottom of <body> tag

this.onload = function() { var test = document.getElementById("pootis"); if(test === null) { console.log("Does not exist"); }else{ console.log("Does exist") } test.innerHTML = "its here"; };
