問題描述

我正在研究如何使用非常強大的 D3(我可以完全推薦用于數據可視化)并找到了 D3 的作者目前所在的 xhr2 分支致力于 xhr POST 請求(和其他請求類型)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.

似乎這是一個全新的功能，因為合并請求來自昨天(2012 年 9 月 18 日):) 出于好奇，我已經想嘗試一下，使用以下代碼序列(我從這個 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");

很遺憾，我收到以下錯誤消息.

Unfortunately I'm getting the following error message.

TypeError: 'undefined' 不是函數(評估'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 縮小版 D3來自 xhr2 分支.有人知道要改變什么嗎?

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

推薦答案

API仍在開發中.如果你想試試看，目前的 API 是這樣的:

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); });

如果您想要完整的請求對象而不僅僅是 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.
