客户端存储数据工具库-PersistJS -优快云博客

本文探讨了使用PersistJS作为替代方案来解决Cookie存储数据的局限性，如大小限制、带宽消耗及复杂性等问题，并对比了Dojo Storage等相似项目。

替代Cookie在客户端存储数据。

Cookie存储数据缺点：

Size: Cookies are limited to about 4 kilobytes in size. Bandwidth: Cookies are sent along with every HTTP transaction. Complexity: Cookies are difficult to manipulate correctly.

PersistJS优点：

Small (9.3k minified, 3k gzipped) Standalone: Does not need any additional browser plugins or JavaScript libraries to work on the vast majority of current browsers. Consistent: Provides a consistent, opaque API, regardless of the browser. Extensible: Custom backends can be added easily. Backwards Compatible: Can fall back to flash or cookies if no client-side storage solution for the given browser is available. Forwards Compatible: Supports the upcoming versions of Internet Explorer, Firefox, and Safari (Opera too, if you have Flash). Unobtrusive: Capability testing rather than browser detection, so newer standards-compliant browsers will automatically be supported

与PersistJS类似功能项目包括：Dojo Storage。遗憾的是DojoStorage依赖Flash，没有安装Flash的浏览器ＤＯＪＯ　ｓｔｏｒａｇｅ不起作用。
