<!DOCTYPE html><html><head> <title>Ajax</title></head><body> <div id = "new"></div> <script type="text/javascript" src = "scripts/addLoadEvent.js"></script> <script type="text/javascript" src = "scripts/getHTTPObject.js"></script> <script type="text/javascript" src = "scripts/getNewContent.js"></script></body></html>這是書上關(guān)于ajax的一個(gè)例子，用ctrl+o在chrome瀏覽器成功運(yùn)行，關(guān)于最后一個(gè)getNewContent函數(shù)，我想問request.send（null）為什么寫在后面？？？
js DOM編程藝術(shù)關(guān)于ajax不太理解的地方
