屬性：method - 要求方法，字串，POST或者GET，預設為POST
　　　url - 請求URL，字串，預設為空白
　　　async - 是否非同步，true為非同步，false為同步，預設為true
　　　content - 請求的內容，如果要求方法為POST需要設定此屬性，預設為空白
backtext -　預設true當backtext=true時返回XMLHttp.responseText為false時返回XMLHttp.responseXML　
gettext 　-　傳回值
　　　callback - 回呼函數，即返迴響應內容時調用的函數，預設為直接返回，回呼函數有一個參數為XMLHttpRequest對象，即定義回呼函數時要這樣：function mycallback(xmlobj)
