browers and html dom 官方解读

Window Object

The window object represents an open window in a browser.

If a document contain frames (<frame> or <iframe> tags), the browser creates one window object for the HTML document, and one additional window object for each frame.

Note: There is no public standard that applies to the Window object, but all major browsers support it.
注解：窗口对象指的是一个在浏览器中打开的窗口。

TIPs : 如果一个html文档包含frames或iframe标签，则浏览器创建一个代表html文档的窗口对象，为每个frame创建一个额外的窗口对象

Window Object Methods

常用方法
alert()，confirm()，从close()什么的就不说了
重点说一下：
open() :
window.open(URL,name,specs,replace)

打开一个空白窗口
var
myWindow = window.open("","","width=200,height=100");

Open
a new window called "MsgWindow", and write some text into it:

var
myWindow = window.open("","MsgWindow","width=200,height=100");
myWindow.document.write("<p>T
c4a9
his is 'MsgWindow'. I am 200px wide and 100px tall!</p>");

再打开的窗口写入内容
