Answer 1

Declare Nick globally ,for now it's scope is limited to onload function only ,also why are you passing Nick as an argument ,you can simply remove it ,and do alert Nick

Answer 2

but how correctly I do not know then I have a mistake

Answer 3

You don't need to pass Nick as an argument to onload function since it's declared globally it's accessible inside any function
your code should be like this,

var nick;
window.onload=()=>{
nick = document.getElementById("nik").value;

};
function inst(){
alert(nick);
}

you will get an empty value when you will click on button which is right

See in your code when the window gets loaded, inside script is executed and therefore it gets the empty value ,and after clicking on button that empty value is seen in alert box

Answer 9

Well, how to get the value out of there?
