You can also go this route, if you want a separate function.

Answer 2

Simply use
window.onload = function str(text){
document.getElementById("demo").innerHTML = "hello" ;
}
to apply the text after page load.
What you are doing is calling this function
function str(text){
document.getElementById("demo").innerHTML = "hello" ;
str("hello"); // This line causes unlimited calls
}
forever.
