我正在尝试在工具提示中显示的表格上添加页脚。在这一行中，我想显示从 json 文件加载的特定数据。

图表：

<script>
    var scene;
    $.getJSON('assets/json/chartc3.json', function (data) {
        scene = data;
        var chart = c3.generate({
            bindto: '#chartc3',
            data:
                {
                    json: scene,
                    keys:
                    {
                        x: 'round',
                        value: ['Marketable', 'Total Requested Capacity', 'Your Bid'],
                    },
                    types: {
                        Marketable: 'area'
                    },
                    colors: {
                        Marketable: '#A09FA2',
                        'Total Requested Capacity': '#272E80',
                        'Your Bid': '#8EBF60'
                    }
                },
            axis:
            {
                x: {
                    tick:
                    {
                        culling:
                        {
                            max: 10
                        }
                    },
                    type: 'category'
                },
                y:

                    min: 0,
                    padding: {
                        bottom: 0

                        format: function (d) { return d3.format(',f')(d) + ' kWh/h' }
                        //or format: function (d) { return '$' + d; }
                    }
                }
            },
            tooltip: {

        valueFormat = config.tooltip_format_value || defaultValueFormat,
        text, i, title, value, name, bgcolor;

                    // You can access all of data like this:
                    for (i = 0; i < d.length; i++) {

                        // ADD
                        if (d[i].name === 'data2') { continue; }


                        if (!text) {
                            title = 'MY TOOLTIP'
                            text = "<table class='" + CLASS.tooltip + "'>" + (title || title === 0 ? "<tr><th colspan='2'>" + title + "</th></tr>" : "");
                        }

                        name = nameFormat(d[i].name);
                        value = valueFormat(d[i].value, d[i].ratio, d[i].id, d[i].index);
                        bgcolor = $$.levelColor ? $$.levelColor(d[i].value) : color(d[i].id);

                        text += "<tr class='" + CLASS.tooltipName + "-" + d[i].id + "'>";
                        text += "<td class='name'><span style='background-color:" + bgcolor + "; border-radius: 5px;'></span>" + name + "</td>";
                        text += "<td class='value'>" + value + "</td>";
                        text += "</tr>";
                    }

                    **var surchargedata;
                    $.getJSON('assets/json/surcharge.json', function(data)

                        console.log(text);
                    })**

                    return text;
                }
            }
        });
    });
</script>

我打印了日志，表格似乎生成得很好，但是如果您查看工具提示：

在此处输入图像描述

我看不到最后一行。

这里生成的表的日志：

    <table class='c3-tooltip'>
    <tr>
        <th colspan='2'>MY TOOLTIP</th>
    </tr>
    <tr class='c3-tooltip-name-Marketable'>
        <td class='name'><span style='background-color:#A09FA2; border-radius: 5px;'>
            </span>Marketable
        </td>
        <td class='value'>5,220,593 kWh/h</td>
    </tr>
    <tr class='c3-tooltip-name-Total Requested Capacity'>
        <td class='name'><span style='background-color:#272E80; border-radius: 5px;'>
            </span>Total Requested Capacity
        </td>
        <td class='value'>16,449,051 kWh/h</td>
    </tr>
    <tr class='c3-tooltip-name-Your Bid'>
        <td class='name'>
            <span style='background-color:#8EBF60; border-radius: 5px;'>
            </span>Your Bid
        </td>
        <td class='value'>100,000 kWh/h
        </td>
    </tr>
    <tr class='c3-tooltip-name-Surcharge'>
        <td class='name'>50.38</td>
        <td class='value'>50.38</td>
    </tr>

生成工具提示时，您正在使用 $.getJSON 加载附加费数据。并且您的附加费行将添加到您为回调中的工具提示生成的文本中。到这个时候，实际的工具提示函数已经返回了在 $.getJSON 调用之前生成的任何文本。

解决此问题的最简单方法是首先通过将附加费 $.getJSON 移动到原始脚本周围来加载附加费数据。

这是更新的脚本。

<script>
    var surchargedata;
    $.getJSON('assets/json/surcharge.json', function (data) {
        surchargedata = data;

        var scene;
        $.getJSON('assets/json/chartc3.json', function (data) {
            scene = data;
            var chart = c3.generate({
                bindto: '#chartc3',
                data:
                    {
                        json: scene,
                        keys:
                        {
                            x: 'round',
                            value: ['Marketable', 'Total Requested Capacity', 'Your Bid'],
                        },
                        types: {
                            Marketable: 'area'
                        },
                        colors: {
                            Marketable: '#A09FA2',
                            'Total Requested Capacity': '#272E80',
                            'Your Bid': '#8EBF60'
                        }
