Question

我正在尝试找到一种解析数据格式的方法，以便HighStocks能够识别它。从服务器获取的数据格式为：

var data = [
    {
        "dt":"2010-06-10 14:33:39",
        "val":98
    },
    {
        "dt":"2010-06-10 14:34:18",
        "val":99
    },
    {
        "dt":"2010-06-10 14:34:28",
        "val":93
    },
    {
        "dt":"2010-06-10 14:34:38",
        "val":79
    },
    {
        "dt":"2010-06-10 14:34:48",
        "val":87
    },
    {
        "dt":"2010-06-10 14:34:58",
        "val":86
    },
    {
        "dt":"2010-06-10 14:35:08",
        "val":79
    },
    {
        "dt":"2010-06-10 14:35:17",
        "val":90
    }]

从Highcharts网站上的演示中，它接受如下格式：

var usdeur = [
[Date.UTC(2003,8,24),0.8709],
[Date.UTC(2003,8,25),0.872],
[Date.UTC(2003,8,26),0.8714],
[Date.UTC(2003,8,29),0.8638],
[Date.UTC(2003,8,30),0.8567],
[Date.UTC(2003,9,1),0.8536],
[Date.UTC(2003,9,2),0.8564],
[Date.UTC(2003,9,3),0.8639],
[Date.UTC(2003,9,6),0.8538],
[Date.UTC(2003,9,7),0.8489]]

简单地说，我如何将数据2010-06-10 14:33:39格式化为Date.UTC(2010,06,10,14,33,39)？任何JavaScript / jQuery方法或者像date.js / moment.js这样的现有库都允许我轻松地这样做（比如说我不想使用getUTC*()来获取日期时间信息然后放入{{1} }）

提前致谢。

为什么不在sql上格式化它？它比格式化图表的每个点要好得多 UNIX_TIMESTAMP应该对你有所帮助示例：
SELECT UNIX_TIMESTAMP(concat(dateColumn, timeColumn)) * 1000 AS 'dateUTC';
