返回上一个页面操作：history.back()

<a href="#" onclick="history.back()">返回</a>

直接跳转到某个页面：window.location.href

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
   "http://www.w3.org/TR/html4/strict.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>js01_hello</title>
    <meta name="author" content="Administrator" />
    <script type="text/javascript">
    function loc() {
        //获取文本框中的值
        var href = document.getElementById("address").value;
        //直接跳转到某个页面
        window.location.href = href;
    }
    </script>
</head>
<body>
    <a href="#" onclick="loc()">test01</a>
    <input type="text" id="address"/>
</body>
</html>

Window对象

当浏览器已加载，就会产生如下代码

<script type="text/javascript">
        with(window){

        }
    </script>
<body>
    <div id="welcome">欢迎进行我们的网站</div>
    <!-- 第二个属性为aaa的，都在同一个窗口显示，名字不同就会重新开一个窗口 -->
    <a href="#" onclick="window.open('test02.html','aaa','width=300,height=300,resizable=0')">test02</a>
    <a href="#" onclick="window.open('test03.html','bbb','width=400,height=400,resizable=0')">test03</a>
    <br/>
    <a href="#" onclick="window.open('bless.html','aaa','width=600,height=300')">输入你祝福语</a>
    <a href="#" onclick="window.open('bless.html','aaa','width=600,height=300')">选择性别</a>
    <div id="bless"></div>
</body>

获取父窗口的方法在Chrome里面无效，在firefox里面可以。

<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>js01_hello</title>
    <meta name="author" content="Administrator" />
    <script type="text/javascript">
    function bless() {
        //获取输入的祝福语
        var mb = document.getElementById("mb").value;
        //获取父类窗口
        var p = window.opener;
        //获取父类窗口中的id为bless的div
        var pd = p.document.getElementById("bless");
        //设置pd的值
        pd.innerHTML = mb;
        //关闭当前窗口
        window.close();
    }
    </script>
</head>
<body>
    输入祝福语:<input type="text" size="40" id="mb"/><input type="button" onclick="bless()" value="输入" />
</body>
</html>
