[Javascript] getElementsByTagName not working ???

[Kim Hoogenberg]

Further more,

Also <script src="file.js"></script> tags cause the browser to fire a 
get request to the server for that file. Then the browser retrieves its 
content if the file exists and then parses all javascript inside before 
moving on to the next html tag on the page.
