javascript - 从 Highstock/Highcharts 获取奇怪的错误信息

Question

我目前正在使用 Highstock/Highcharts，我不想通过我拥有的 json 文件加载数据。当我尝试获取数据时，它在控制台中显示了一条我以前从未见过的错误消息:

highstock.js:456 Uncaught TypeError: f.data.slice is not a function

我正试图通过这个函数获取 json 数据。我只在输入 data.json 的 url 时收到此错误消息:

$.each(names, function (i, name) {

        var dataUrl = 'http://local.priceservice.dev/js/data.json';

        $.getJSON(dataUrl,    function (data) {

            seriesOptions[i] = {
                name: name,
                data: data
            };

            // As we're loading the data asynchronously, we don't know what order it will arrive. So
            // we keep a counter and create the chart when all the data is loaded.
            seriesCounter += 1;

            if (seriesCounter === names.length) {
                createChart();
            }
            console.log(data)
        });
    });

我以前从未见过该消息，我尝试四处搜索，但找不到与我有相同问题的人。

JSON:

系列中的数据必须是数组。该系列至少需要一个对象，其数据格式如下:

series: [{
   data: [...] // <- has to be an array
}]

你的系列看起来像这样:

series: [{
   name: ...,
   data: { // <- you put an object instead of an array with points
      "priceSeries": ...
   }
}]

上面的代码导致 slice 被对象调用，就像这样

var someObj = {};
someObj.slice(); // Uncaught TypeError: someObj.slice is not a function(…)

你应该这样走:http://jsfiddle.net/r3xfxymm/1/
