How to call external javascript on window.load?

Question

I want to post this on my website

<script type="text/javascript"> <!-- window.onload = hello; function
hello() { var name = prompt("What is your name", "") alert ( "Hello "
+ name + "! Welcome to my forum.") } </script>

but I do not want to put it in the index, but in a separate file, say hello.js

How can I call it from an index file, so when I click on index.html it immediately asks for my name. (eg)

I put it <script src="hello.js"></script>does not work.

Answer 1

Your hello.js should look something like this:

window.onload = hello; 

function hello() { 
    var name = prompt("What is your name", "");
    alert("Hello " + name + "! Welcome to my forum."); 
}

and then <script src="hello.js"></script>should work fine.
