javascript - 如何显示在 Highcharts 中找不到数据

Question

在highcharts中，如果json值中没有找到数据，我想显示一条错误消息。

我使用了这段代码:

if(options.series[0].data.length == 0) {
    alert('nodatafound');
} else {
    var chart = new Highcharts.Chart(options);
}

出现此错误:

TypeError: options.series[0].data is undefined

来自 JSON 的数据:

{
    "chart": {
        "renderTo": "container2",
        "type": "column",
        "marginRight": 10,
        "marginBottom‌": 125
    },
    "title": {
        "text": "",
        "x": -20
    },
    "exporting": {
        "enabled": false
    },
    "credits": {
        "enab‌led": false

    "xAxis": {

            }
        }
    },
    "yAxis": {
        "title": {
            "text": ""
        },
        "plotLines": [{

                "color": "white"
            }
        }
    },
    "series": [{
        "name": "2015-16-Q1"
    }, {
        "name": "2015-16-Q2"
    }, {
        "name": "2015-16-Q3"
    }, {
        "na‌me": "2015-16-Q4"
    }]
}

您可以使用no-data module这允许这样做。
