Answer 1

use addEventListener (in this way listeners added will stack automatically) rather than assigning to window.onload ( it will contain whatever was previously assigned to it ):

or you can putt all your code into the same onload method:

Answer 2

put all the function outside the window.onload function then just call all of them in the window.onload function
