I was doing a research on how to make POST requests using the amazingly powerful D3 (which I can fully fully recommend for data visualization) and found the xhr2 branch where the authors of D3 are currently working on xhr POST request (and other request types) support.
Seems like it is a brand new feature as the merge request is from yesterday (18 September 2012) :) And as curious I am I already wanted to try it out, using the following code sequence (which I have from this location)
d3.text("localhost/test",function(d) { console.log(d)})
.method("POST")
.setRequestHeader("Content-type", "application/x-www-form-urlencoded")
.data("a=1&b=2&c=3");
Unfortunately I'm getting the following error message.
TypeError: 'undefined' is not a function (evaluating 'd3.text("localhost/test",function(d) { console.log(d)}) .method("POST")')
I'm using the minified D3 version from the xhr2 branch. Anybody an idea what to change?
