数据更改时饼图数据不更新

Question

我正在尝试生成我的项目的报告。这些报告在饼图的帮助下显示。我得到了正确的响应数据，但饼图没有在第一次请求中更新。我必须再发送 2-3 个请求，然后它才会更新饼图。我的js代码在这里：

//Pie chart for product
            var dataLeadproduct = google.visualization.arrayToDataTable(pieproductdataLeadSummery);
            var productLeadoptions = {
                title: 'Top Product',
                pieHole: 0,
                pieSliceText: '',
                pieSliceBorderColor: '#00ffffff',
                colors: ['#FF772D', '#57c8f2', '#8175c7', '#ff6c60', '#A9D86E'],
                chartArea: {left: 20, top: 10, width: '100%', height: '75%'},
                is3D: false,
                reverseCategories: false,
                'tooltip.text': 'value'
            };
            var productLeadSummery = new google.visualization.PieChart(document.getElementById('leadsummeryproduct_piechart'));
            productLeadSummery.draw(dataLeadproduct, productLeadoptions);

CI的控制器代码：

//Product Pie Chart
                $leadProduct_query = 'SELECT COUNT(lead_product_id) AS lead_product_count, lead_product_id FROM leads WHERE lead_id IN (' . implode(',', $leadsID) . ') AND lead_location_id ="' . $leadsummery_city . '" AND lead_progress LIKE \'%:"' . $leadsummery_stages . '";%\' AND lead_loan_amount >="' . $leadsummery_amount_from . '" AND lead_loan_amount <="' . $leadsummery_amount_to . '" AND lead_reg_date <="' . $leadsummery_startdate . '" AND lead_reg_date >="' . $leadsummery_enddate . '" GROUP BY lead_product_id ORDER BY COUNT(lead_product_id) DESC limit 5';
                $leadProduct = $this->db->query($leadProduct_query)->result_array();
                $leadProduct_count = count($leadProduct);

                foreach ($leadProduct as $lp) {
                    $product_name[] = $this->Generalmodel->getfromid('products', 'product_name', $lp['lead_product_id']);
                    $pro_percent[] = round(($lp['lead_product_count'] / $leads_count) * 100);
                }

                $tempLeadPro[] = array('Product Name', 'Count');
                for ($i = 0; $i < $leadProduct_count; $i++) {
                    $proData = array($product_name[$i], $pro_percent[$i]);
                    $tempLeadPro[] = $proData;
                    $leadSummeryProductpiedata = $tempLeadPro;
                }

问题已解决。原因是 google.charts.setOnLoadCallback(drawLeadSummeryChart);。因为我在同一个 jquery 中多次使用 setOnLoadCallback。因此，它总是在控制台 "Uncaught Error: Container is not defined" 中显示错误并且无法加载响应。所以我只是检查视图页面中的 id 长度是否大于 0。如果它大于则执行 setOnLoadCallback。代码如下：

if ($('#IDFROMVIEWPAGE').length > 0) {
                google.charts.setOnLoadCallback(drawLeadSummeryChart);
            }
