Change:
e.target.classList.contains('key_1')
by:
e.target.className.includes('key_1')
If loginDisplay is an input label, change:
if (e.target.classList.contains('key_1')) {
let valu = loginDisplay.innerHTML;
loginDisplay.innerHTML=valu+'1';
}
by:
if (e.target.className.includes('key_1')) {
loginDisplay.value += '1';
}
