利用地址栏URL传值
A页面传值
<input type="text" id="txt">
</br>
<input type="button" value="TEST" onclick="test()"/>
<SCRIPT LANGUAGE="JavaScript">
function
test(){
var s =document.getElementById("txt");
location.href="2.html?"+"txt="+encodeURI(s.value);
}
</SCRIPT>
B页面接受并打印
<script language="javascript" type="text/javascript">
var loc=location.href;
var n1=loc.length;//地址的总长度
var n2=loc.indexOf("=");//取得=号的位置
var id=decodeURI(loc.substr(n2+1, n1-n2));//从=号后面的内容
alert(id);//
document.write(id)
</script>
利用H5 Web 存储 传值
A页面传值
<h1>利用HTML5 Web 存储 localStorage</h1>
<div onclick="save(1)">添加1</div>
<div onclick="save(2)">添加2</div>
<div onclick="save(3)">添加3</div>
<div onclick="save(4)">添加4</div>

利用JavaScript Cookie存储 传值
(
cookie储存是需要服务器支持的，
本地直接运行静态文件是实现不了的，
需要给静态文件搭建服务器支持；
例如：打开后的地址栏为
http://192.168.1.5:809/2.html
)
