last line document.getElementById("check").onlick = checkAnimal() Don't call your function. checkAnimal then parenthesis () It mean your code calls that function immediately. So put your function name without parenthesis. Like document.getElementById("check"). onclick = checkAnimal;

Why dont you cache the DOM first and then write the logic cause this has happened with me multiple times where nothing is wrong and it doesn't work.

xavi Nope. Without parenthesis that doesn't means that a function call. Copying the blue print of that particular function definition. into that position. When you click that button the function will be triggered

You can also add a function event via addEventListener method. HTMLElement.addEventListener("event type", functionName, {userCapture,...})
