It also provides +conveniences for long-polling applications such as retries, exponential +backoff between requests, and randomized request delaying. + +Dependencies: + + json2.js + +Available Transports: + + XmlHttpRequest - for all modern CORS browsers + JSON-P - for IE7, IE8, IE9, and older versions of other browsers + +Limitations: + + - Responses from the server must be in JSON format. This library will parse + the data and return an object to the application. + - If the JSON-P transport is used, the request headers and body are subject + to URI length limitations of the browser and server. + - It is not possible to inspect the headers of a response. + +Usage: + + var req = new PollDance.Request(); + req.on('finished', function(code, result) { ... }); + req.on('error', function(reason) { ... }); + var headers = { ... }; + var body = 'some data'; + req.start('POST', 'http://example.com/path', headers, body); + +JSON-P Protocol: + + This library supports JSON-P by supplying the following query string + parameters in the request: + + callback: the JavaScript function to call in the response + method: the method name (default GET) + headers: additional headers encoded as JSON (default none) + body: request body (default empty) + + This protocol dictates that the presence of the "callback" parameter + signifies the request as a JSON-P request. The remaining parameters are + optional. + + The server is expected to reply with a JSON object of the form: + + { + "status": code, + "value": object + } diff --git a/README.md b/README.md deleted file mode 100644 index d1b44e6..0000000 --- a/README.md +++ /dev/null @@ -1,4 +0,0 @@ -polldance -========= - -JavaScript AJAX/long-polling library \ No newline at end of file -- cgit v1.2.3
