JavaScript对象(窗口对象 定时器对象 )
1：窗口时间
confirm(str)：确认对话框，确认返回trun，取消返回false，但是必须要有两个return；不然就算按下取消也会提交
第一个return：用于保证确认按钮运行
<script>
function update(){
var r = confirm("go on updating?");
return r;
}
</script>
第二个return：用于保证取消按钮也能运行
<form>
<input type="text" name="user"/>
<input type="submit" value="提交" onclick="return update()">

2:页面控制：window.open()控制打开页面
1：按钮控制打开多个
2：按钮控制打开一个，后面加上该网页的内容
<body>
<input type="button" value="可重复打开新的窗口" onclick="window.open('window对象.html')"/>
<input type="button" value="只能打开一个新的窗口" onclick="window.open('window对象.html','window对象')"/>
</body>
变成超链接的方式：
<a href="javascript:window.open('window对象.html','window对象')">windows对象</a>
打开网页的三种方式：
1：替换当前页面：
2：重复打开同一个连接：
3：同一个链接只能打开一次：
<p><a href="window对象.html">替换当前页面</a></p>
<p><a href="window对象.html" target="_blank">打开另一个选项卡</a></p>
<p><a href="#"onclick="javascript:window.open('window对象.html','window对象')">只能打开一次</a></p>
定时器对象：
多用于网页动态时钟，制作倒计时，跑马灯效果
周期性时钟：页面的倒计时
一次性时钟：等5s后关闭页面
往网页里面写回东西：
var s = hour+'小时'+minute+'分钟'+second+'秒';
h1.innerHTML = s;//任意元素中间的
页面一打开就执行函数：
window.addEventListener('load',miaosha,false)
秒杀：
var timer;
var miaosha = function(){
var h1 = document.getElementById("time");
var now= new Date();
//距离6点开始抢购
var hour = 19-now.getHours()-1;
var minute=59- now.getMinutes();
var second = 59- now.getSeconds();
var s = hour+'小时'+minute+'分钟'+second+'秒';
h1.innerHTML = s;//任意元素中间的正文 }
window.addEventListener('load',timerStart,false) function timerStart(){
timer = window.setInterval(miaosha,1000);
}
在JavaScript中，===表示完全相等，需要判断一个变量未定义，必须给他加上===等号
function stopTimer(){
if(timer===undefined)
timer = window.setInterval(miaosha,1000);
else
timer=clearInterval(timer);
}
页面5s后关闭：
var timere;
function timeFunc(){
var h1= document.getElementById("h1");
var n =parseInt(h1.innerHTML);
h1.innerHTML = (n-1)+"s后自动关闭"
}
function startTimer(){
timere = setInterval(timeFunc,1000);
}
window.addEventListener('load',startTimer,false);
