Question

我正在尝试使用本教程https://www.highcharts.com/docs/getting-started/your-first-chart实现Highcharts，但是会收到此错误：

未捕获（承诺）错误：Highcharts错误＃13：www.highcharts.com/errors/13

这意味着div要渲染到不存在，但我很确定我的代码中有一个正确类的div：

<html>
<head>

    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <!--link custom css file-->
    <link rel="stylesheet" type="text/css" href="/css/style.css">
</head>
<body>
    <div class="container">
        <h1 class="text-center">Your Dashboard</h1>
        <div class="row">
            <div class="col-xs-7">
                <h3 class="text-center">Calories Today</h3>
                <div class="top-left" id="cal-line">
                </div>
            </div>
            <div class="col-xs-5">
                <h3 class="text-center">Calories Over Time</h3>
                <div class="top-right" id="cal-today" style="width:100% height:400px;">
                </div>
            </div>
        </div>
    </div>
</body>
</html>

这是我在/js/dashboard.js中的JS：

/*global React*/
/*global ReactBootstrap*/
/*global ReactDOM*/
/*global fetch*/
/*global location*/
/*global Highcharts*/
/*global $*/

//variable to hold user data from API fetch
let user = {};

const fb_id = location.pathname.replace("/users/","");

$(document).ready(function() {

fetch("https://www.url.com/usersdata/" + fb_id)
        .then(rsp => rsp.json())
        .then(json => {
        //we fetched the user data    
            if(json.error && json.error.message){
                throw new Error(json.error.message);
            } 

            user = json;
            console.log(json);

            $(function(){
               const myChart = Highcharts.chart('top-right',{

                 chart:{
                     type: 'bar'
                 },
                 title:{
                     text: 'Calories Over Time'
                 },
                 xAxis:{
                     categories: ['Apples', 'Bananas', 'Oranges']
                 },
                 yAxis:{
                     title:{
                         text: 'Fruit eaten'
                     }
                 },
                 series: [{
                     name: 'Jane',
                     data: [1,0,4]
                 },{
                     name: 'John',
                     data: [5,7,3]
                 }]

               });

            });

        });

});

任何人都可以帮助我，我做错了什么？

在<div>标记内，您应该使用“ id”而不是“ class”来引用图表。

此外，当您引用包含highchart的外部js时，请将其添加到body标签中而不是头部中。

这来自我的工作代码。

<html>

<head>
    <script src="https://code.highcharts.com/highcharts.js"></script>
    <script src="https://code.highcharts.com/modules/exporting.js"></script>
    <script src="https://code.highcharts.com/modules/export-data.js"></script>
    <link rel="stylesheet" type="text/css" href="sytlels.css">
</head>

<body>
    <div id="container"></div>
    <script src="highChart.js"></script>
</body>

</html>
