问题描述

我正在研究如何使用非常强大的 D3(我可以完全推荐用于数据可视化)并找到了 D3 的作者目前所在的 xhr2 分支致力于 xhr POST 请求(和其他请求类型)支持.

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.

似乎这是一个全新的功能，因为合并请求来自昨天(2012 年 9 月 18 日):) 出于好奇，我已经想尝试一下，使用以下代码序列(我从这个 位置)

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");

很遗憾，我收到以下错误消息.

Unfortunately I'm getting the following error message.

TypeError: 'undefined' 不是函数(评估'd3.text("localhost/test",function(d) { console.log(d)}).method("POST")')

TypeError: 'undefined' is not a function (evaluating 'd3.text("localhost/test",function(d) { console.log(d)}) .method("POST")')

我正在使用 缩小版 D3来自 xhr2 分支.有人知道要改变什么吗?

I'm using the minified D3 version from the xhr2 branch. Anybody an idea what to change?

推荐答案

API仍在开发中.如果你想试试看，目前的 API 是这样的:

The API is still under development. If you want to try it out, the current API is like so:

d3.text("/test")
    .header("Content-type", "application/x-www-form-urlencoded")
    .post("a=1&b=2&c=3", function(error, text) { console.log(text); });

如果您想要完整的请求对象而不仅仅是 responseText，您也可以直接使用 d3.xhr 而不是 d3.text.

You can also use d3.xhr rather than d3.text directly if you want the full request object rather than just the responseText.

更新到最新的 API.

Updated to latest API.
