Solve this. Options

[Maccabee]

My teacher showed me, but I forgot and cant find what it is called or how to solve it.

CODE

function get_name(name)
{
    // test to make sure it is a string that isn't empty
    // test to make sure that it is at least 3 characters long
    // test to make sure that it is either Paul, John or Bob and no one else
    alert("Hi " + name);
}

How can I tell it what name is? and it would be mice if someone could tell me how to tell it the name too. Something like:

CODE

var name = prompt("What is your name?","");

This is javascript btw. Not php. I keep getting confused too...

I have watched all the lynda.com javascript tutorials and all the w3schools.com javascript tutorials and for some reason I cant solve this. Thanks.

I know. But I have no options left. and he is being very kind. I have watched two whole series of javascript tutorials and none of them tell me how to do this. Im just now trying to figure out how to tell it, what the name is.
