我使用Chart.js，我想從 DIV 元素內(nèi)的屬性中提取數(shù)據(jù)。我可以在data-gpget和中獲取數(shù)據(jù) data-gpret。它寫入控制臺，但不將其視為“數(shù)據(jù)”數(shù)據(jù)。data: getATT('#graph3','data-gpval')這可能data: getATT('#graph3','data-gpret') 是什么原因？我缺少什么？謝謝。<div id="graph3" data-gpget="[28,12,14,27,11]" data-gpret="[21,64,32,73,76]"> <canvas id="js-chartjs-earnings"></canvas></div>JS：function getATT(id,value) { return $(id).attr(value);}return e = a, t = [{ key: "initCharts", value: function () {Chart.defaults.scale.gridLines.color = "transparent", Chart.defaults.scale.gridLines.zeroLineColor = "transparent", Chart.defaults.scale.ticks.beginAtZero = !0, Chart.defaults.global.elements.line.borderWidth = 0, Chart.defaults.global.elements.point.radius = 0, Chart.defaults.global.elements.point.hoverRadius = 0, Chart.defaults.global.tooltips.cornerRadius = 3, Chart.defaults.global.legend.labels.boxWidth = 12; var r, a = jQuery(".js-chartjs-earnings"); r = { labels: ["MON", "TUE", "WED", "THU", "FRI", "SAT", "SUN"], datasets: [{ label: "GETTING", fill: !0, data: getATT('#graph3','data-gpget') }, { label: "RETURNS", fill: !0, data: getATT('#graph3','data-gpret') }] },
從 DIV 元素獲取圖形數(shù)據(jù)
