Question

我正在尝试使用 Highcharts 图表 API 在网格中创建折线图、柱形图和饼图。但是我收到错误“未捕获的语法错误:意外的 token 非法”。从几个小时开始挠我的头。引用链接:http://www.highcharts.com/demo/com

    Really appreciate the help.

您的 JavaScript 代码中有一个 HTML 特殊实体字符(& 代表 &)。试试这个方法:

 <apex:page>
     <script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
     <script src="https://code.highcharts.com/highcharts.js"></script>
     <script src="https://code.highcharts.com/modules/exporting.js"></script>
     <div id="container" style="min-width: 310px; height: 400px; margin:0 auto"></div>

        <script>
            $(function () {
            $('#container').highcharts({
            title: {
            text: 'Combination chart'
            },
            xAxis: {
                categories: ['Apples', 'Oranges', 'Pears', 'Bananas', 'Plums']
            },
                    labels: {
                    items: [{
                    html: 'Total fruit consumption',
                    style: {
                    left: '50px',
                    top: '18px',
                   color: (Highcharts.theme && Highcharts.theme.textColor)||'black' // remove the HTML-like "&" encoding...
                    }
                }]
            },
              series: [{
                    type: 'column',
                    name: 'Jane',
                    data: [3, 2, 1, 3, 4]
                    }, {
                     type: 'column',
                    name: 'John',
                   data: [2, 3, 5, 7, 6]
                    }, {
                    type: 'column',
                    name: 'Joe',
                    data: [4, 3, 3, 9, 0]
                    }, {
                    type: 'spline',
                    name: 'Average',
                    data: [3, 2.67, 3, 6.33, 3.33],
                    marker: {
                    lineWidth: 2,
                    lineColor: Highcharts.getOptions().colors[3],
                    fillColor: 'white'
                  }
                }, {
                type: 'pie',
                name: 'Total consumption',
                data: [{
                    name: 'Jane',
                    y: 13,
                    color: Highcharts.getOptions().colors[0] 
                  }, {
                    name: 'John',
                    y: 23,
                    color: Highcharts.getOptions().colors[1] 
                    }, {
                    name: 'Joe',
                    y: 19,
                    color: Highcharts.getOptions().colors[2] 
                }],
                center: [100, 80],
                size: 100,
                showInLegend: false,
                dataLabels: {
                    enabled: false
                    }
                }]
            });
        });

        </script>
  </apex:page>

我也包含了一个 jQuery CDN 引用。我不知道 Highcharts 是否需要它。
