Question

我已经连续使用了4个图表，2个甜甜圈和2个饼。该代码在chrome，Edge，Firefox和Internet Explorer以外的其他浏览器上都可以正常工作。请帮忙..！！！下面是代码：

$(document).ready(function() {


    var randomScalingFactor = function() {
        return Math.round(Math.random() * 100);
        //return 0;
    };
    var randomColorFactor = function() {
        return Math.round(Math.random() * 255);
    };
    var randomColor = function(opacity) {
        return 'rgba(' + randomColorFactor() + ',' + randomColorFactor() + ',' + randomColorFactor() + ',' + (opacity || '.3') + ')';
    };

Answer 1

将分配移至window.onload

window.onload = function() {
    window.myDoughnut = new Chart(document.getElementById("doughnutChart"), DoughtnutConfig);
    window.myDoughnut1 = new Chart(document.getElementById("doughnutChart1"), DoughtnutConfig1);
    window.myPie = new Chart(document.getElementById("pieChart"), PieConfig);
    window.myPie1 = new Chart(document.getElementById("pieChart1"), PieConfig1);
};

这是不需要的，因为代码已经在jquery的-> $(document).ready

内部

window.myDoughnut = new Chart(document.getElementById("doughnutChart"), DoughtnutConfig);
window.myDoughnut1 = new Chart(document.getElementById("doughnutChart1"), DoughtnutConfig1);
window.myPie = new Chart(document.getElementById("pieChart"), PieConfig);
window.myPie1 = new Chart(document.getElementById("pieChart1"), PieConfig1);

请参阅以下工作片段...

$(document).ready(function() {
    var randomScalingFactor = function() {
        return Math.round(Math.random() * 100);
        //return 0;
    };
    var randomColorFactor = function() {
        return Math.round(Math.random() * 255);
    };
    var randomColor = function(opacity) {
        return 'rgba(' + randomColorFactor() + ',' + randomColorFactor() + ',' + randomColorFactor() + ',' + (opacity || '.3') + ')';
    };

    // doughnut example
    var DoughtnutConfig = {
        type: 'doughnut',
        data: {
            datasets: [{
