加載一個只包含button控件的SAP UI5腳手架應用：
http://localhost:3000/wt/

18 requests
1.1 MB transferred over network
5.1 MB resources loaded by the page
DOM content loaded 1.19s:當純HTML被完全加載以及解析時，DOMContentLoaded 事件會被觸發，而不必等待樣式表，圖片或者子框架完成加載。
Load: 3.06s

一個易混用但不同的事件是，load,這個事件僅僅應該在探測到整個頁面完全加載完成時被使用。一個常見的錯誤就是在該使用DOMContentLoaded的地方使用了load.
