Permission to use, copy, modify, and/or distribute this software for any You can access last version before ES6 on githack. protobuf.js is a pure JavaScript implementation with TypeScript support for node.js and the browser. WARNING: starting from this website is using some ES6 features, which can break it for older browsers (though it is still working on IE11). Protocol Buffers are a language-neutral, platform-neutral, extensible way of serializing structured data for use in communications protocols, data storage, and more, originally designed at Google ( see ). Hovering on the tree highlights ancestry (the hovered node and all its ancestors get colored) and the position of the hovered node gets highlighted in the hex dump (with header and content in a different colors).Ĭlicking a node in the tree will hide its sub-nodes (collapsed nodes can be noticed because they will become italic). On the left of the page will be printed a tree representing the hierarchical structure, on the right side an hex dump will be shown. This tool can be used online at the address or offline, unpacking the ZIP file in a directory and opening index.html in a browser ![]() This is really the ideal solution for the future.This page contains a JavaScript generic ASN.1 parser that can decode any valid ASN.1 DER or BER structure whether Base64-encoded (raw base64, PEM armoring and begin-base64 are recognized) or Hex-encoded. If you control what browser is being used or you are not worried people with an older browser, you can always use the JSON.parse method. Here is an example of using the eval function: var strJSON = ')()") This is not recommended if you are getting the JSON object from another source that isn't absolutely trusted because the eval function allows for renegade code if you will. On the other hand, if you don't want to use a library and you can vouch for the validity of the JSON object, I would simply wrap the string in an anonymous function and use the eval function. Unless you need to support IE 7 or Firefox 3.0, the correct way to parse JSON is JSON.parse().įirst of all, you have to make sure that the JSON code is valid.Īfter that, I would recommend using a JavaScript library such as jQuery or Prototype if you can because these things are handled well in those libraries. From a modern perspective, parsing JSON by involving jQuery or calling eval() is nonsense. The advice given here is no longer applicable and probably dangerous. The atob() function decodes a string of data. For this reason, it’s important to set the charset of any JavaScript document. If not specified otherwise, the browser assumes the source code of any program to be written in the local charset, which varies by country and might give unexpected issues. ![]() This answer stems from an ancient era of JavaScript programming during which there was no builtin way to parse JSON. In JavaScript there are two functions respectively for decoding and encoding base64 strings: atob() btoa(). Encoding ASCII chars Unicode encoding of source files. ![]()
