let picture = document.getElementById('image1');
function moveLeftArrow () {
picture.style.left = parseInt(picture.style.left) - 5 + 'px';
}
This code is designed to allow users to move images using the arrow keys. Interestingly, the function works as expected when the variable picture is declared locally, but encounters issues when declared globally. Why might this be the case?
There are no issues related to scope.
Since I am unable to view the entire code, my assumption is that the problem lies in this particular line where it is triggered when the DOM element does not exist.
var element = document.getElementById("image1");
Suggest trying to utilize window.onload.
