javascript - D3日期解析: Uncaught TypeError

Question

我试图理解datetime parsing在 D3.js 中。

为什么以下不起作用？它一直给我Uncaught TypeError: Object 2012-06-01 12:00:00+0000 has no method 'getFullYear。

var parseDate = d3.time.format("%Y-%m-%d %H:%M:%S+%Z");
var datestr = '2012-06-01 12:00:00+0000';

console.log('d.datestr', datestr, typeof datestr);
console.log(parseDate(datestr));

两个问题:

要解析日期，您需要使用 format.parse :

var format = d3.time.format("%Y-%m-%d");
format.parse("2011-01-01"); // returns a Date
format(new Date(2011, 0, 1)); // returns a string

Additionally :

The %Z directive (time zone offset, such as "-0700") is not yet supported for parsing.
