parser only and support for IE browsers(before IE10) about protobuf.js HOT 5 CLOSED

Imho it's not worth the trouble to extract only the parser from the library as all of its output is made for ProtoBuf.js only and there usually is no other library that understands it. However, it should be possible to use the general build without modifications and to just call the parser only, which is located at ProtoBuf.DotProto.Parser. As far as I am concerned, this should not break in IE as long as none of the unsupported features are actually used. Or am I wrong?

As far as i know, IE(before IE10) doesn't support ArrayBuffer. So I remove encode and decode function.And also, IE8 doesn't support Object.keys and eval not works great as well.When using ProtoBuf.js with IE8, it will report some error. So i add some code to fix that.

how can i use to support ie8, can you give me a example? thx

Thanks marchtea, I appreciate your efforts!

Regarding IE8 support in general: ProtoBuf.js respectively ByteBuffer.js relies on the typed array specification for efficient encoding and decoding, which unfortunately isn't supported in older browsers. There are, however, polyfills available to support typed arrays in one or another way and, if you load these before ProtoBuf.js, it should theoretically work within IE<9: For me, the most promising one is: https://github.com/inexorabletash/polyfill/blob/master/typedarray.js

ByteBuffer.js itself has been patched a few months ago to explicitly support polyfills like that: protobufjs/bytebuffer.js#5

Hope this helps!
