我正在尝试使用gridstack.js和chart.js在PHP yii2项目中制作仪表板
我提供了一个下拉按钮，用户可以在其中选择 KPI 图表，所选图表将添加到 gridstack.js 的网格中
问题 1：如果我按增量顺序加载图表：图表 1、图表 2、图表 3...等等，它会在网格中初始化，没有任何问题。但是，如果我选择图表 1 以外的任何随机图表，则所选图表不会被初始化。
问题2：一旦网格被保存，然后加载。因此，如果用户想要向加载的网格再添加一个图表，以便他/她可以更新已保存的网格 => 创建一个新网格并且加载的网格消失。
我100%确定问题出在initializeChart函数上。我根据网上可用的资源尝试了多种方法，但都是徒劳。我尝试过的一些事情是：
但是一旦我修改了initializeChart函数，甚至没有一个图表被初始化。而目前如果以增量顺序调用它们正在初始化。
下面是我的完整代码。请帮我解决问题。
注意：我删除了一些图表数据以适应限制。所有图表数据都是虚构的，因此您可以复制粘贴任何图表数据并重命名以使其正常工作。
附注任何帮助将不胜感激。预先感谢！

我设法解决了图表初始化问题。基本上在我的下面的函数中，我将选定的图表添加到 advanceItems 数组中，并且有一个用于图表初始化的函数。
我为每个图表的初始化创建了单独的函数，并从 advanceItems 数组中的画布元素中提取了所选图表 id，并为所选的每个 canvasElement 调用该函数。下面是有效的更新代码
document.addEventListener('DOMContentLoaded', function () {
document.querySelectorAll('.dropdown-item').forEach(function (item) {
item.addEventListener('click', function () {
const chartType = this.innerText.toLowerCase();
const chartId = chartType + 'Chart';
// console.log(chartId);
// console.log(typeof (chartId));
const newChart = `<canvas id="${chartId}"></canvas>`;
// Check if the chart already exists in advanceItems
const itemContent = advanceItems.find(item => item.content);
console.log("NEW CHART ", newChart);
console.log("SELECTED item.content", itemContent);
const existingChart = advanceItems.find(item => item.content.includes(newChart));
if (!existingChart) {
// Calculate new x and y coordinates based on existing items
const newX = advanceItems.length % 2 === 0 ? 8 : 0; // Alternates between 0 and 8
const newY = Math.floor(advanceItems.length / 2) * 2;
advanceItems.push({
id: chartId, // Add an id property to uniquely identify the chart
x: newX,
y: newY,
w: 6,
h: 4,
content: newChart,
});
advanceItems.forEach((n, i) => {
n.id = String(i);
if (!n.content.includes('removeWidget')) {
n.content = `<button class="btn btn-outline-secondary" onclick="removeWidget(this.parentElement.parentElement)">X</button><br> ${n.content ? n.content : ''}`;
}
});
// Reload the grid to reflect the changes
grid.load(advanceItems);
// Mapping between chart IDs and initialization functions
const chartInitializationMap = {
'occupancyChart': initializeOccupancyChart,
'roomsChart': initializeRoomsChart,
'contractsChart': initializeContractsChart,
'employeeChart': initializeEmployeeChart,
'revenueChart': initializeRevenueChart,
'invoicesChart': initializeInvoicesChart,
'paymentChart': initializePaymentChart,
'visitorsChart': initializeVisitorsChart,
'maintenanceChart': initializeMaintenanceChart,
};
// Extract canvas elements using regular expression
const canvasElements = advanceItems.map(selectedGraph => {
const matches = selectedGraph.content.match(/<canvas.*?<\/canvas>/);
return matches ? matches[0] : null;
}).filter(Boolean);
console.log("Canvas elements:", canvasElements);
// Call the corresponding initialization functions based on the canvas IDs
canvasElements.forEach(canvasElement => {
const chartIdMatch = canvasElement.match(/id="([^"]+)"/);
if (chartIdMatch) {
const chartId = chartIdMatch[1];
const initializationFunction = chartInitializationMap[chartId];
if (initializationFunction) {
initializationFunction();
}
}
});
}
});
});
});
单独的图表功能如下：
function initializeOccupancyChart(chartContent) {
// Add your existing chart initialization code here
// Make sure that this code is executed after the grid is loaded
// You might also need to modify this function to target the correct chart container
// based on the chartId.
console.log("in the initializeOccupancyChart function", chartContent, typeof (chartContent))
const ctxOccupancy = document.getElementById('occupancyChart');
