發(fā)現(xiàn)一個(gè)奇怪的事
在export to global object那里，在執(zhí)行過(guò)一次代碼后，再次重復(fù)執(zhí)行一遍代碼
chrome會(huì)在DetectorBase那行提示
Uncaught TypeError: Cannot redefine property: DetectorBase(…)
firefox則會(huì)在LinkDetector那里提示
TypeError: can't redefine non-configurable property "LinkDetector"
代碼是一樣的，三個(gè)property的順序是LinkDetector,ContainerDetector,DetectorBase
