window对象是JavaScript浏览器对象模型中的顶层对象,包含多个常用方法和属性: 
1 打开新窗口 
 
window.open(pageURL,name,parameters) 
 
其中: 
pageURL为子窗口路径 
name为子窗口句柄 
parameters为窗口参数(各参数用逗号分隔) 
如: 
 
window.open("http://www.cnblogs.com/zhouhb/","open",'height=100,width=400,top=0,left=0,toolbar=no,menubar=no,scrollbars=no,resizable=no,location=no,status=no'); 
 
2 打开模式窗口 
 
window.showModalDialog("http://www.cnblogs.com/zhouhb/","open","toolbars=0;width=200;height=200"); 
 
3 关闭窗口,不弹出提示框 
如果网页不是通过脚本程序打开的(window.open()),调用window.close()脚本关闭窗口前,必须先将window.opener对象置为null,否则浏览器(IE7、IE8)会弹出一个确定关闭的对话框。 
 
<script language="javaScript"> 
function closeWindow() 
{ 
 window.opener = null; 
 window.open('', '_self', ''); 
 window.close(); 
} 
</script> 
<input type='button' value='关闭窗口' onClick="closeWindow()"> 
或 
<input type="button" value="关闭窗口" onClick="window.opener = null; 
window.open('', '_self', '');window.close()"> 
 
对于关闭框架窗口 
 
<script language="javaScript"> 
function closeWindow() 
{ 
window.opener = null; 
window.open('', '_top', ''); 
window.parent.close(); 
} 
</script> 
 
4 location对象使用 
 
window.location.reload();//刷新当前页 
window.location.href="http://www.cnblogs.com/zhouhb/"; //载入其他页面 
 
5 history对象使用 
 
window.history.go(1); //前进 
window.history.go(-1); //后退 
 
6 子窗体向父窗体传值 
6.1 简单方法 
(1)在父窗体中打开子窗体 
 
var str=window.showModalDialog("s.html"); 
if(str!=null) 
{ 
var v=document.getElementById("v"); 
v.value+=str; 
} 
 
(2)子窗体代码 
 
var v=document.getElementById("v"); 
window.parent.returnValue=v.value; 
window.close(); 
 
另外,对于showModalDialog打开的窗口,也可以通过dialogArguments传值: 
父窗口代码: 
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>无标题文档</title> 
<script type="text/javascript"> 
function opendialog() 
{ 
window.showModalDialog("child.html",window,"win","resable=false");//这里用window对象作为参数传递 
} 
</script> 
</head> 
<body> 
<form> 
<input type="text" id="name" /> 
<input type="button" id="open" value="open" onclick="opendialog()"/> 
</form> 
</body> 
</html> 
 
子窗口代码: 
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>无标题文档</title> 
<script type="text/javascript"> 
function updateParent() 
{ 
var pwin=window.dialogArguments;//子窗口获取传递的参数 
if(pwin!=undefined) 
{ 
pwin.document.getElementById("name").value=document.getElementById("name").value; 
} 
} 
</script> 
</head> 
<body> 
<form> 
<input type="text" id="name" /> 
<input type="button" id="update" value="更新父窗口" onclick="updateParent()"/> 
</form> 
</body> 
</html> 
 
对于showModalDialog打开的窗口,也可以通过window.returnValue传值: 
主窗口: 
 
<SCRIPT type="text/javascript"> 
function openWindow(){ 
var bankCard=window.showModalDialog("counter.html","","dialogWidth=400px;dialogHeight=200px"); 
alert("您的银行卡密码是"+bankCard+"/n"); 
} 
</SCRIPT> 
 
(2)打开的窗口 
 
<HEAD> 
<META http-equiv="Content-Type" content="text/html; charset=gb2312"> 
<TITLE>窗口练习</TITLE> 
<SCRIPT type="text/javascript" language="javascript"> 
function closeWindow(){ 
window.returnValue=document.myform.cardPass.value; 
window.close(); 
} 
</SCRIPT> 
</HEAD> 
<BODY> 
<FORM name="myform" action="" method="post"> 
账户信息:<BR> 
请妥善保存你的账户信息,以免发生损失<BR> 
帐号:<INPUT name="cardNum" type="text" size="40"><BR> 
密码:<INPUT name="cardPass" type="password" size="45"><BR> 
<INPUT type="button" name="btn" value="确认" onClick="closeWindow()"> 
</FORM> 
</BODY> 
 
6.2 更加详细的介绍 
众所周知window.open() 函数可以用来打开一个新窗口,那么如何在子窗体中向父窗体传值呢,其实通过window.opener即可获取父窗体的引用。 
如我们新建窗体FatherPage.htm: 
 
<script type="text/javascript"> 
function OpenChildWindow() 
{ 
window.open('ChildPage.htm'); 
} 
</script> 
<input type="text" id="txtInput" /> 
<input type="button" value="OpenChild" onclick="OpenChildWindow()" /> 
 
然后在ChildPage.htm中即可通过window.opener来访问父窗体中的元素: 
 
<script type="text/javascript"> 
function SetValue() 
{ 
window.opener.document.getElementById('txtInput').value 
=document.getElementById('txtInput').value; 
window.close(); 
} 
</script> 
<input type="text" id="txtInput" /> 
<input type="button" value="SetFather" onclick="SetValue()" /> 
 
其实在打开子窗体的同时,我们也可以对子窗体的元素进行赋值,因为window.open函数同样会返回一个子窗体的引用,因此FatherPage.htm可以修改为: 
 
<script type="text/javascript"> 
function OpenChildWindow() 
{ 
var child = window.open('ChildPage.htm'); 
child.document.getElementById('txtInput').value 
=document.getElementById('txtInput').value; 
} 
</script> 
<input type="text" id="txtInput" /> 
<input type="button" value="OpenChild" onclick="OpenChildWindow()" /> 
 
通过判断子窗体的引用是否为空,我们还可以控制使其只能打开一个子窗体: 
 
<script type="text/javascript"> 
var child 
function OpenChildWindow() 
{ 
if(!child) 
child = window.open('ChildPage.htm'); 
child.document.getElementById('txtInput').value 
=document.getElementById('txtInput').value; 
} 
</script> 
<input type="text" id="txtInput" /> 
<input type="button" value="OpenChild" onclick="OpenChildWindow()" /> 
 
光这样还不够,当关闭子窗体时还必须对父窗体的child变量进行清空,否则打开子窗体后再关闭就无法再重新打开了: 
 
<body onunload="Unload()"> 
<script type="text/javascript"> 
function SetValue() 
{ 
window.opener.document.getElementById('txtInput').value 
=document.getElementById('txtInput').value; 
window.close(); 
} 
function Unload() 
{ 
window.opener.child=null; 
} 
</script> 
<input type="text" id="txtInput" /> 
<input type="button" value="SetFather" onclick="SetValue()" /> 
</body>
