一、弹出框

<script type="text/javascript">
window.onload=function(){
window.alert("msg alert");
var msg =window.prompt("prompt", "hello"); //msg hello 或者null

alert(msg);
var msg1=window.confirm("hahah"); //msg1 true false;
alert(msg1);

//alert prompt confirm

};
</script>

二、open

<script type="text/javascript">

function openW(){
//定义自己的外观
window.open("window2.html","mypage","width=500,height=500,titlebar=yes,resizable=yes",true);
}
</script>
</head>
<body>
<input type="button" onclick="openW()" value="打开新窗体"/>
</body>

三、window.setInterval

<script type="text/javascript">
//window.self属性 代表当前的窗体
//window.setInterval("函数名()",时间戳); 每隔时间戳 执行一次函数
var id=window.self.setInterval("clock()",1);
function clock(){
var t=new Date();
document.getElementById("clock").value=t;
}

function cls(){
window.self.clearInterval(id);
}
</script>
</head>

<body>
<!-- 输入框 -->
<input type="text" id="clock" size="35" />
<input type="button" value="清空操作" onclick="cls()"/>
</body>

四、window.setTimeout

<script type="text/javascript">
//window.self属性 代表当前的窗体
//window.setTimeout("函数名()",时间戳); 隔时间戳后 执行一次函数
var id=window.self.setTimeout("clock()",3000);
function clock(){
var t=new Date();
document.getElementById("clock").value=t;
//id=window.self.setTimeout("clock()",3000);
}

function cls(){
window.clearTimeout(id);
}

//面试题
</script>
</head>

<body>

<!-- 输入框 -->
<input type="text" id="clock" size="35" />

<input type="button" value="清空操作" onclick="cls()"/>

</body>

五、Location

<script type="text/javascript">
function goUrl()
{

alert(window.location.host);
alert(window.location.hostname);
alert(window.location.port);
alert(window.location.protocol);
alert(window.location.search);
window.location.href="http://www.baidu.com";

}
</script>
</head>

<body>
<input type="button" value="发送新的请求" onclick="goUrl()"/>
</body>

六、History

1.html

<body>
<a href="2.html">进入2.html</a>

<a href="./l.html?name=chj">进入l.html</a>
</body>

2.html

<body>
<!-- <a href="javascript:history.back()">返回1.html</a> -->
<a href="javascript:history.go(-1)">返回1.html</a>
<a href="3.html">进入3.html</a>
<!-- <a href="javascript:history.forward()">前进</a> -->
<a href="javascript:history.go(1)">前进</a>
</body>

3.html
