window.onload should be a function - it will trigger when the document 
has loaded. You, however, assign it the return value of a function.

window.onload=BuildSelect;

will assign the function itself to the onload handler. However, you are 
losing the argument if you do thus. How to fix that?

window.onload=function(){
     BuildSelect(arr);
}
