Because you element doesn't exist const rButton; window.onload = function() { rButton = document.getElementById("removeBtn"); rButton.disabled = true; }

You must make sure that DOM is avaible at getElementById time else any call for get elements references return null.... Try to wrap your js code in a function that set like window onload listener: window.onload= function(){ // your js code here }
