Also, you may try to "map" actions:

var box     = document.getElementById('box'),
    buttons = box.getElementsByTagName('button');

var map = [
    'editcustomerform',
    'deletecustomer',
    'emailcustomer',
    'callcustomer',
    'gpstocustomer',
    'createquote',
    'createsalesorder',
    'createcashsale'
];

for(var i = 0; i < buttons.length; i++){
    buttons[i].id = [ 'my', 'button', 'id', i ].join('-');
    buttons[i].onclick = function(){ location.href = [ '/scape', map[i], 'id' ].join('/'); }
}
