jquery - 悬停时删除工具提示上的背景颜色淡出效果

Question

当我将鼠标悬停在工具提示上时，当我从工具提示中移动鼠标时，背景颜色会淡出。任何帮助将不胜感激。

我试图弄清楚是哪个代码产生了这种奇怪的效果。我已经尝试了几乎可能的解决方案。

谢谢 ：）

这是我用来对齐标签右侧的代码：

  Chart.Tooltip.prototype.drawBody = function(pt, vm, ctx) {
    var bodyFontSize = vm.bodyFontSize;
    var bodySpacing = vm.bodySpacing;
    var bodyAlign = vm._bodyAlign;
    var body = vm.body;
    var xLinePadding = 0;
    var textColor;

    ctx.textAlign = bodyAlign;
    ctx.textBaseline = 'top';
    ctx.font = Chart.helpers.fontString(bodyFontSize, vm._bodyFontStyle, vm._bodyFontFamily);

    pt.x = getAlignedX(vm, bodyAlign);
    // Before Body
    var fillLineOfText = function(line) {
        let cols = line.split(':');
        if (bodyAlign == 'left' && cols.length > 1) {
            line = cols.slice(0, cols.length-1).join(':') + '';
            let rightText = cols.slice(-1);
            ctx.textAlign = 'right';
            let x = getAlignedX(vm, 'right');
            ctx.fillText(rightText, x, pt.y);
            ctx.textAlign = 'left';
        }
        ctx.fillText(line, pt.x + xLinePadding, pt.y);
        pt.y += bodyFontSize + bodySpacing;
    };

    // Draw body lines now
    Chart.helpers.each(body, function(bodyItem, i) {
        textColor = vm.labelTextColors[i];
        ctx.fillStyle = textColor;

        Chart.helpers.each(bodyItem.lines, function(line) {
            fillLineOfText(line);
        });
    });

    // After body lines
    Chart.helpers.each(vm.afterBody, fillLineOfText);
    pt.y -= bodySpacing; // Remove last body spacing */
}

这是图表js的代码：

var chart = new Chart(ctx, {
    // The type of chart we want to create
    type: 'bar',
    responsive: true,

    // The data for our dataset
    data: {
        labels: {!! json_encode($labelsArray) !!},
        datasets: [
            {
                label: 'Time',
                fill: true,
                data: ["", "", "", "", "", "", "", "", "", "", "", "", "", "", ""],
                backgroundColor: gradient,
                hoverBackgroundColor: gradient,
            }
        ]
    },

    border: 'none',
    borderColor: 'transparent',
    borderJoinStyle: 'none',

    // Configuration options go here
    options: {

        },
        tooltips: {
            position: "average",

            xAlign: 'center',
            yAlign: 'bottom',
            bodyFontStyle: 'bold',
            callbacks: {
                label: function (tooltipItem, data) {
                    if (tooltipItem.yLabel >= 460) {
                        chart.options.tooltips.yAlign = 'top'
                    } else {
                        chart.options.tooltips.yAlign = 'bottom'
                    }
                    var data = chartTooltipData[tooltipItem.xLabel];

                    if (data == undefined) {
                        return [
                            'Reaction : ' + tooltipItem.yLabel + ' ms'
                        ];
                    }
                        $('.test-list ul li.active h3.heavy').text().trim() == 'VISUAL DIGITAL SPAN') {
                        return [

                        ]
