Create a Tooltip for a ForeignObject Element Hover in OrgChart JS

How to Create a Tooltip for a ForeignObject Element Hover in OrgChart JS: A Beginner’s Guide

Creating tooltips can enhance user interaction with your organization chart, providing additional information in an intuitive and visually appealing manner. In this tutorial, we will guide you through the steps to create a tooltip for a foreignObject element hover in OrgChart JS, a powerful library for visualizing organizational charts.

Code example

Step 1: Setting Up Your Environment

First, make sure you have OrgChart JS integrated into your project. You can include the OrgChart JS library in your HTML file:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>OrgChart with Tooltip</title>
    <script src="https://cdn.balkan.app/orgchart.js"></script>
</head>
<body>
    <div id="tree"></div>
    <script src="path/to/your-script.js"></script>
</body>
</html>

Replace "path/to/your-script.js" with the actual path to your JavaScript file. Add all the bellow code in your-script.js

Step 2: Creating SVG Elements

Define your SVG elements and tooltip structure:

let drive = `<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 48 48" width="48px" height="48px">
<path fill="#1e88e5" d="M38.59,39c-0.535,0.93-0.298,1.68-1.195,2.197C36.498,41.715,35.465,42,34.39,42H13.61 c-1.074,0-2.106-0.285-3.004-0.802C9.708,40.681,9.945,39.93,9.41,39l7.67-9h13.84L38.59,39z"/>
<path fill="#fbc02d" d="M27.463,6.999c1.073-0.002,2.104-0.716,3.001-0.198c0.897,0.519,1.66,1.27,2.197,2.201l10.39,17.996 c0.537,0.93,0.807,1.967,0.808,3.002c0.001,1.037-1.267,2.073-1.806,3.001l-11.127-3.005l-6.924-11.993L27.463,6.999z"/>
<path fill="#e53935" d="M43.86,30c0,1.04-0.27,2.07-0.81,3l-3.67,6.35c-0.53,0.78-1.21,1.4-1.99,1.85L30.92,30H43.86z"/>
<path fill="#4caf50" d="M5.947,33.001c-0.538-0.928-1.806-1.964-1.806-3c0.001-1.036,0.27-2.073,0.808-3.004l10.39-17.996 c0.537-0.93,1.3-1.682,2.196-2.2c0.897-0.519,1.929,0.195,3.002,0.197l3.459,11.009l-6.922,11.989L5.947,33.001z"/>
<path fill="#1565c0" d="M17.08,30l-6.47,11.2c-0.78-0.45-1.46-1.07-1.99-1.85L4.95,33c-0.54-0.93-0.81-1.96-0.81-3H17.08z"/>
<path fill="#2e7d32" d="M30.46,6.8L24,18L17.53,6.8c0.78-0.45,1.66-0.73,2.6-0.79L27.46,6C28.54,6,29.57,6.28,30.46,6.8z"/>
</svg>`;

let tooltip = '<g data-t-id="{id}" transform="matrix(0.001,0,0,0.001,{x},{y})" ><path stroke="#FFCA28" fill="#fff" d="M 0,0 L -10,-10 H -85 Q -90,-10 -90,-15  V -65   Q -90,-70 -85,-70 H 85 Q 90,-70 90,-65 V -15 Q 90,-10 85,-10 H 10  L 0,0 z" ></path>{text}</g>';

let tooltipText = '<text text-anchor="middle" data-width="130" fill="#F57C00" x="0" y="-32">{val}</text>';

Step 3: Customizing the OrgChart Template

Customize the OrgChart template to include the SVG foreignObject and tooltip:

OrgChart.templates.ana.html = '<foreignobject class="node" style="font: 13px Helvetica;" x="20" y="10" width="200" height="100">' + drive + '{val}</foreignobject>';

let chart = new OrgChart(document.getElementById("tree"), {
  mode: 'dark',
  mouseScrool: OrgChart.action.none,
  nodeMouseClick: OrgChart.action.none,
  template: "ana",
  enableSearch: false,
  nodeBinding: {
    field_0: "name",
    html: "html",
    tooltip: 'tooltip'
  },
  nodeMenu: {
    details: { text: "Details" },
    edit: { text: "Edit" },
    add: { text: "Add" },
    remove: { text: "Remove" }
  }
});

Step 4: Adding Event Listeners for Hover Effects

Add event listeners to handle the tooltip display on mouseenter and mouseleave events:

chart.on('redraw', function (sender) {
  let fieldElements = sender.element.querySelectorAll('[data-n-id] foreignobject svg');
  for (let i = 0; i < fieldElements.length; i++) {
    let fieldElement = fieldElements[i];
    fieldElement.addEventListener('mouseenter', function () {
      let id = this.parentElement.parentElement.getAttribute('data-n-id');
      let tooltipElement = document.querySelector('[data-t-id="' + id + '"]');
      if (!tooltipElement) return;
      let transformStart = OrgChart._getTransform(tooltipElement);
      let transformEnd = transformStart.slice(0);
      transformEnd[0] = 1;
      transformEnd[3] = 1;
      OrgChart.animate(tooltipElement, { transform: transformStart }, { transform: transformEnd }, 300, OrgChart.anim.outBack);
    });
    fieldElement.addEventListener('mouseleave', function () {
      let id = this.parentElement.parentElement.getAttribute('data-n-id');
      let tooltipElement = document.querySelector('[data-t-id="' + id + '"]');
      if (!tooltipElement) return;
      let transformStart = OrgChart._getTransform(tooltipElement);
      let transformEnd = transformStart.slice(0);
      transformEnd[0] = 0.001;
      transformEnd[3] = 0.001;
      OrgChart.animate(tooltipElement, { transform: transformStart }, { transform: transformEnd }, 300, OrgChart.anim.inBack);
    });
  }
});

Step 5: Rendering the Tooltip

Render the tooltip when the chart is drawn:

OrgChart.events.on('render', function (sender, args) {
  for (let i = 0; i < args.res.visibleNodeIds.length; i++) {
    let node = sender.getNode(args.res.visibleNodeIds[i]);
    let data = sender.get(node.id);
    if (data.tooltip) {
      args.content += tooltip
        .replace('{x}', node.x + node.w / 2)
        .replace('{y}', node.y + 5)
        .replace('{id}', node.id)
        .replace('{text}', tooltipText.replace('{val}', OrgChart.wrapText(data.tooltip, tooltipText)));
    }
  }
});

Step 6: Loading Chart Data

Finally, load the chart data and include tooltips:

chart.load([
  { id: "1", html: "<div>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi id pellentesque lacus.</div>", tooltip: '1 my fancy tooltip' },
  { id: "2", pid: "1", html: "<div>Mauris aliquam magna sapien. Ut a diam ac arcu commodo maximus.</div>", tooltip: '2 my fancy tooltip' },
  { id: "3", pid: "1", html: "<div>Phasellus eros felis, pellentesque quis ultrices nec, tempus ac felis.</div>", tooltip: '3 my fancy tooltip' }
]);

By following these steps, you can easily add tooltips on a foreignObject element hover in your OrgChart JS.
