How to show/hide input value on focus?

forms, hide, input, javascript, show

Solution

This always worked for me:

<input 
    type="text" 
    value="Name:"
    name="visitors_name" 
    onblur="if(value=='') value = 'Name:'" 
    onfocus="if(value=='Name:') value = ''"
 />

Problem

I see this all over the web, but was wondering if anyone has the JavaScript code for the EASIEST way to show input value on blur, but hide in on focus.
