Pros: convenient argument can be cross-domain.
Disadvantages: the value of the length of the limited
two: JavaScript static pages Cookie articles of value transfer
. Cookie is a browser stores a small amount of named data
associated with it together with a particular page or site.
Cookie use to provide memory to the browser,
so that the script and server programs can use the input data to another page in a page.

优点:可以在同源内的任意网页内访问.生命期可以设置.
缺点:值长度有限制.
三：JavaScript静态页面值传递之Window.open篇
这两窗口之间存在着关系.父窗口parent.htm打开子窗口son.htm
子窗口可以通过window.opener指向父窗口.这样可以访问父窗口的对象.
Post.htm
<input type=text name=maintext>
<input type=button value="Open">
Read.htm
<script language="javascript" >
//window.open打开的窗口.
//利用opener指向父窗口.
var parentText = window.opener.document.all.maintext.value;
alert(parentText);
</script
优点:取值方便.只要window.opener指向父窗口,就可以访问所有对象.不仅可以访问值,还可以访问父窗口的方法.值长度无限制.
缺点:两窗口要存在着关系.就是利用window.open打开的窗口.不能跨域.
