Question

我有这个功能：

    $(function () {
            // declaration 
$("#thermogauge").ejLinearGauge({
                labelColor: "#8c8c8c", load: "loadGaugeTheme",
                height: 400, width: 250, drawLabels: "DrawLabel", drawCustomLabel: "DrawCustomLabel", enableAnimation: false,
                scales: [{
                    type: "thermometer", backgroundColor: "transparent", minimum: -10, maximum: 110, minorIntervalValue: 5, scaleBarSize: 20, position: { x: 50, y: 18 }, length: 200, border: { width: 0.5 },
                    showCustomLabels: true,
                    markerPointers: [{ opacity: 0 }],
                    barPointers: [{
                        width: 10, distanceFromScale: -0.5,
                        value: 0, backgroundColor: "#DB3738"
                    }],
                    labels: [{
                        placement: "near", font: { size: "10px", fontFamily: "Segoe UI", fontStyle: "Normal" }
                    }, {
                        placement: "far",
                        distanceFromScale: { x: 10 }
                    }],
                    ticks: [{
                        type: "majorinterval", height: 8, width: 1, color: "#8c8c8c", distanceFromScale: { y: -4 }
                    }, {
                        type: "minorinterval", height: 4, width: 1, color: "#8c8c8c", distanceFromScale: { y: -4 }
                    }, {
                        type: "majorinterval", placement: "far", height: 8, width: 1, color: "#8c8c8c", distanceFromScale: { y: -4 }
                    }, {
                        type: "minorinterval", placement: "far", height: 4, width: 1, color: "#8c8c8c", distanceFromScale: { y: -4 }
                    }],
                    customLabels: [{
                        value: "(° C)",
                        position: { x: 44, y: 70},
                        font: "bold 12px Segoe UI", color: "#666666"
                    }, {
                        value: "(° F)",
                        position: { x: 56, y: 70},
                        font: "bold 12px Segoe UI", color: "#666666"
                    },
                    {
                        position: { x: 51, y: 75},
                        font: "bold 13px Segoe UI",
                        color: "#666666"
                    }]
                }]
            });
        });

我想更改＆＃39; value＆＃39;在该函数之后的变量，如下所示：

$('#thermogauge').ejLinearGauge('value', 60);

但它不起作用。我认为其原因在于＆＃39; barPointers＆＃39;但我不知道如何改变它...... 你能帮助我吗？

您可以查看可用的不同功能here，但看起来您需要执行以下操作之一：

$('#thermogauge').data("ejLinearGauge").setBarPointerValue(0,0,30);
$('#thermogauge').data("ejLinearGauge").setIndicatorValue(0,0,30);
$('#thermogauge').data("ejLinearGauge").setPointerValue(0,0,30);

在jquery中定义函数后更改函数变量
