WorldWind学习笔记[一]
//编码escape 解码unescape
document.write(escape("複雜的中文中國龍")+"<br/>");
//%u8907%u96DC%u7684%u4E2D%u6587%u4E2D%u570B%u9F8D
document.write(escape((escape("複雜的中文中國龍")))+"<br/>");
//%25u8907%25u96DC%25u7684%25u4E2D%25u6587%25u4E2D%25u570B%25u9F8D
//一次escape编码后%u8907如果改成\u8907就是Unicode码表示方式，如果传到Java里用
//request.getParameter("name");获取，% 还要再编码，用两次escape就可以把%变成%25
//这样request.getParameter("name")就能拿到%u8907这样的字符串，用Escape.java转成汉字就可以
//如果用encodeURI同样由于%问题在js也要用两次再传给Java，那么Java里就可以用自带的java.net.URLDecoder。
