User interactions in EJ2 JavaScript Maps control

6 Mar 202424 minutes to read

Zooming, panning, single and double click, highlight and selection are all options that allow for effective interaction with Map elements.

Zooming

The zooming feature is used to zoom in and out of Maps to show in-depth information. It is controlled by the zoomFactor property of the zoomSettings of the Maps. The zoomFactor is increased or decrease dynamically based on zoom in and out interaction.

Enable Zooming

Zooming of Maps is enabled by setting the enable property of zoomSettings to true. To enable Zooming in Maps, the Zoom module must be injected into Maps using Maps.Inject(Zoom) method.

Enable panning

To enable the panning feature, set the enablePanning property of zoomSettings to true.

var map = new ej.maps.Maps({
    zoomSettings: {
        enable: true,
		enablePanning:true
    },
    layers: [{
        shapeData: world_map,
    }]
});
map.appendTo('#element');

Various type of zooming

Zooming can be performed in following types:

Zooming toolbar

By default, the toolbar is rendered with zoom-in, zoom-out, and reset options when it is set to true in the enable property of zoomSettings.

The following options are available in toolbar.

  1. Zoom - Provides rectangular zoom support.
  2. ZoomIn - Zooms in the Maps.
  3. ZoomOut - Zooms out the Maps.
  4. Pan - Switches to panning if rectangular zoom is activated.
  5. Reset - Restores the Maps to the default view.

Refer the API links for Zooming.

var map = new ej.maps.Maps({
    zoomSettings: {
        enable: true,
        toolbarSettings: {
           buttonSettings: {
              toolbarItems: ['Zoom', 'ZoomIn', 'ZoomOut', 'Pan', 'Reset'],
           }
        }
    },
    layers: [{
        shapeData: usa_map,
    }]
});
map.appendTo('#element');

Pinch zooming

To enable or disable the pinch zooming, use the pinchZooming property in zoomSettings.

var map = new ej.maps.Maps({
    zoomSettings: {
        enable: true,
        pinchZooming: true
    },
    layers: [{
        shapeData: usa_map,
    }]
});
map.appendTo('#element');

Single-click zooming

To enable or disable the single-click zooming, use the zoomOnClick property in zoomSettings.

var map = new ej.maps.Maps({
    zoomSettings: {
        enable: true,
        zoomOnClick: true
    },
    layers: [{
        shapeData: usa_map,
    }]
});
map.appendTo('#element');

Double-click zooming

To enable or disable the double-click zooming, use the doubleClickZoom property in zoomSettings.

var map = new ej.maps.Maps({
    zoomSettings: {
        enable: true,
        doubleClickZoom: true
    },
    layers: [{
        shapeData: usa_map,
    }]
});
map.appendTo('#element');

Mouse wheel zooming

To enable or disable mouse wheel zooming, use the mouseWheelZoom property in zoomSettings.

var map = new ej.maps.Maps({
    zoomSettings: {
        enable: true,
        mouseWheelZoom: true
    },
    layers: [{
        shapeData: usa_map,
    }]
});
map.appendTo('#element');

Minimum and maximum zooming

The zooming range can be adjusted using the minZoom and maxZoom properties in zoomSettings. The minZoom value is set to 1 by default, and the maxZoom value is set to 10.

var map = new ej.maps.Maps({
    zoomSettings: {
        enable: true,
        minZoom: 2,
        maxZoom: 12
    },
    layers: [{
        shapeData: usa_map,
    }]
});
map.appendTo('#element');

Zooming with animation

To zoom in or zoom out the Maps with animation, use the animationDuration property in layers.

var map = new ej.maps.Maps({
    zoomSettings: {
        enable: true,
    },
    layers: [{
        shapeData: usa_map,
        animationDuration: 500

Public method for the shape selection

The shapeSelection method can be used to select each shape in the Maps.
LayerIndex, propertyName, country name, and selected value as a boolean state(true / false) are the input parameters for this method.

var map = new ej.maps.Maps({
    layers: [{
        shapeData: world_map,
        selectionSettings: {
            enable: true,
            fill: 'green',
            border: { color: 'white', width: 2}
        }
    }]
});
map.appendTo('#element');
document.getElementById('selection').onclick = () => {
        map.shapeSelection(0, "continent", "Asia", true);
};
document.getElementById('unselection').onclick = () => {
    map.shapeSelection(0, "continent", "Asia", false);
};

Initial shape selection

The shape is initially selected using the initialShapeSelection property, and the values are mapped to the shapePath and shapeValue.

initialShapeSelection is an Array property.

var map = new ej.maps.Maps({
    layers: [{
        shapeData: world_map,
        initialShapeSelection: [
            { shapePath: 'continent', shapeValue: 'Africa' },

        ],
        selectionSettings: {
            enable: true,
            fill: 'green',
            border: { color: 'white', width: 2}
        }

Enable highlight for polygons

The polygon shapes can be highlighted via user interaction if the enable property of highlightSettings is set to true. The following properties are available in highlightSettings to customize the polygon shape when it is highlighted.

  • fill - It is used to change the color of the highlighted polygon shape.
  • opacity - It is used to change the opacity of the highlighted polygon shape.
  • border - This property is used to change the color, width, and opacity of the border of the highlighted polygon shape.

The following example shows how to highlight a polygon shape on a geometry map.

var map = new ej.maps.Maps({
    layers: [
        {
            shapeData: world_map,

Tooltip

On mouse over or touch end event, the tooltip is used to get more information about the layer, bubble, or marker. It can be enabled separately for layer or bubble or marker by using the visible property of tooltipSettings as true. The valuePath property in the tooltip takes the field name that presents in data source and displays that value as tooltip text. The tooltipDisplayMode property is used to change the display mode of the tooltip in Maps. Following display modes of tooltip are available in the Maps component. By default, tooltipDisplayMode is set to MouseMove.

var map = new ej.maps.Maps({
    layers: [{
        shapeData: world_map,
        tooltipSettings: {
            visible: true,
            valuePath: 'name'
        }
    }]
});

Customization

The following properties are available in the tooltipSettings to customize the tooltip of the Maps component.

  • fill - Applies the color of the tooltip in layers, markers, and bubbles of Maps.
  • format - To customize the format of the tooltip in layers, markers, and bubbles of Maps
  • textStyle - To customize the style of the text in the tooltip for layers, markers, and bubbles of Maps.

Tooltip template

The HTML element can be rendered in the tooltip of the Maps using the template property of the tooltipSettings. In the following example, ${value1} and ${value2} are the place holders in the HTML element to display the value1 and value2 values of the corresponding shape.

var map = new ej.maps.Maps({
