done: false,
onload: [],
loaded: function() {
if (DomLoaded.done) return;
DomLoaded.done = true;
if (document.removeEventListener) {
document.removeEventListener('DOMContentLoaded', DomLoaded.loaded, false);
}
for (i = 0; i < DomLoaded.onload.length; i++) DomLoaded.onload[i]();
},
load: function(fireThis) {
this.onload.push(fireThis);
if (document.addEventListener) {

return DomLoaded.loaded();
} catch (e) {}
