7.1文档对象模型

7.1.1文档对象模型（DOM）：各种浏览器对象形成一个层次模型

7.1.2 如何引用对象浏览器

引用Document对象，使用Window.document;

引用screen对象时，使用window.screen;

引用forms对象时，使用window.document.forms;

引用text对象时，则应该使用window.document.forms.text;

可以在使用对象在数组中的位置（下标）来引用，如：window.docuemnt.form\[0\]或使用name属性来访问，如对name为form1的对象：window.document.form1来引用

7.2 使用window对象

7.2.1 window对象包含的属性、方法

7.2.2使用window对象

window对象的属性和方法的引用：window.属性和window.方法

window对象还可以使用标识符self代替：self.属性和 self.方法

还可以省略window，直接写出

7.2.3打开或关闭一个窗口

1、打开窗口：当window.open方法执行时，它不但按照指定的参数打开了新建的窗口，而且还创建了这个新窗口的引用

open(URL,window name\[,window features\])

Window features是新创建窗口的实际特性，可能的参数包括：height、width、left、top、toolbar、location、directories、status、menubar、scrollbars、resizable、outerHeight、outerWidth

2、关闭窗口

window.close()

7.2.4 进行定时设置

定时方法包括：setTimeout（）和clearTimeout（）以及setInterval（）和clearInterval（）

1、setTimeout（）和clearTimeout（）

variable=setTimeout(expression,time)

setTimeout()方法的作用是在time所规定的时间之后，执行expression一次。

例如：timer=setTimeout（showMessage（）,1000)

clearTimeout(timer):clearTimeout()括号内的timer就是setTimeout()方法返回的值。这个方法的作用是中断setTimeout（）设定的定时操作。

2、setInterval（）和clearInterval（）

variable=setInterval(expression,time,\[args\])

7.25.5 window对象的其他重要操作

7.3使用frame对象

7.3.1在窗口中生成帧

ROWS、COLS

NAME、SRC、SCROLLING、MARGINWIDTH、MARGINHEIGHT、NORESIZE

7.3.2访问窗口中的帧

window.framename

window.frames\[index\]

window.frames\['framename'\]
