javascript - 将数据作为 js 变量传递给 highchart

Question

我有一个关联的 php 数组(field_data)，我想使用 json_encode 将它传递给 JS功能:$jArray = json_encode($field_data);我正在 JS 中接收数组:var irbrowser = <?php echo $jArray; ?>;但是在js中，当我想将jArray中的值设置为饼图数据时，它不会渲染任何内容。

 <?php
        $jArray = json_encode($field_data);
?>

<div dir="ltr" id="container"> </div>

<script>
    var irbrowser = <?php echo $jArray; ?>;

    $(function () {
    $('#container').highcharts({
        chart: {
            plotBackgroundColor: null,
            plotBorderWidth: null,
            plotShadow: false,
            type: 'pie'
        },
        title: {
            text: 'Browser market shares'
        },
        tooltip: {
            pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
        },
        plotOptions: {
            pie: {
                allowPointSelect: true,
                cursor: 'pointer',
                dataLabels: {
                    enabled: true,
                    format: '<b>{point.name}</b>: {point.percentage:.1f} %',
                    style: {
                        color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
                    }
                }
            }
        },
        series: [{
            name: "Brands",
            colorByPoint: true,
            data: [{
                name: "IE",
                y: irbrowser.IE
            }, {
                name: "Chrome",
                y: irbrowser.Chrome,
                sliced: true,
                selected: true
            }, {
                name: "Proprietary or Undetectable",
                y: irbrowser.Other
            }]
        }]
    });
});

 </script>

我发现了问题。应将其转换为浮点型。所以我使用parseFloate(irbrowser)函数。并将变量设置为 y。该代码

series: [{
        name: "Brands",
        colorByPoint: true,
        data: [{
            name: "IE",
            y: parseFloat(irbrowser.IE)
        }, {
            name: "Chrome",
            y: parseFloat(irbrowser.Chrome),
            sliced: true,
            selected: true
        }, {
            name: "Proprietary or Undetectable",
            y: 0.5
        }]
    }]
