Answer 1

here is my html

 
    

        Welcome To My Home
    
    

        I am a student at Columbia College of Missouri.
    

And so this is how I did something similar in javaScript

var myGlobalNameHolder ="";

function myFunction(){
var myString = prompt("Enter a name", "Name Goes Here");
    myGlobalNameHolder = myString;
    if (myString != null) {
        document.getElementById("replaceME").innerHTML =
        "Hello " + myString + ". Welcome to my site";

        document.getElementById("belong").innerHTML =
        "A place you belong";
    }   
}

// create a function to pass our event too
function myFunction2(event) {   
// variable to make our event short and sweet
var x=window.onbeforeunload;
// logic to make the confirm and alert boxes
if (confirm("Are you sure you want to leave my page?") == true) {
    x = alert("Thank you " + myGlobalNameHolder + " for visiting!");
}
}
