Client side data compress/decompress?
提问by simo
I'm looking for a JavaScript implementation of a string compress/decompress algorithm where data is created at the client side and stored in hidden fields within HTML forms.
我正在寻找字符串压缩/解压缩算法的 JavaScript 实现，其中数据在客户端创建并存储在 HTML 表单中的隐藏字段中。
I read about gzip, but it compresses the data server side whereas in my case I want to compress it client side, send it to the server, or receive it from server to decompress it again at client side.
我阅读了gzip，但它压缩了数据服务器端，而在我的情况下，我想将其压缩到客户端，将其发送到服务器，或从服务器接收它以在客户端再次解压缩。
I found this LZF Compressionexample based on LZFjsbut it will generate binary data which needs to be processed and stored in a hidden form field, and it works on files rather than pure data.
我发现了这个基于LZFjs 的LZF 压缩示例，但它会生成需要处理和存储在隐藏表单字段中的二进制数据，并且它适用于文件而不是纯数据。
Suggestions on a pure data client-side data compression/decompression that is also efficient?
关于纯数据客户端数据压缩/解压缩也很有效的建议？

Googling around, I also found this zlib implementation (not tested by me) : http://nodejs.org/api/zlib.html
谷歌搜索，我还发现了这个 zlib 实现（未经我测试）：http: //nodejs.org/api/zlib.html

You may also try JSZip. To run it in browser you just have to downloadand include dist/jszip.js or dist/jszip.min.js.
你也可以试试JSZip。要在浏览器中运行它，您只需下载并包含 dist/jszip.js 或 dist/jszip.min.js。
This is actively supported and supports a wide variety of browsers including everyone's favorite IE6/7/8!
这是积极支持的，支持各种浏览器，包括大家最喜欢的IE6/7/8！
Usage (from their docs):
用法（来自他们的文档）：
var zip = new JSZip(); zip.file("Hello.txt", "Hello World\n"); var img = zip.folder("images"); img.file("smile.gif", imgData, {base64: true}); var content = zip.generate({type:"blob"});
var zip = new JSZip(); zip.file("Hello.txt", "Hello World\n"); var img = zip.folder("images"); img.file("smile.gif", imgData, {base64: true}); var content = zip.generate({type:"blob"});
