User interactions in EJ2 TypeScript Maps control
13 Jun 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. The following code snippet demonstrates injecting the Zoom module into the Maps component.
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({ });Enable panning
To enable the panning feature, set the enablePanning property of zoomSettings to true.
import { world_map } from './world-map.ts';
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
layers: [{
shapeData: world_map,
}],
zoomSettings:{
enable:true,
enablePanning:true
}
});
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.
- Zoom - Provides rectangular zoom support.
- ZoomIn - Zoom in the Maps.
- ZoomOut - Zoom out the Maps.
- Pan - Switches to panning if rectangular zoom is activated.
- Reset - Restores the Maps to the default view.
import { usmap } from 'usa.ts';
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
zoomSettings: {
enable: true,
toolbarSettings: {
buttonSettings: {
toolbarItems: ['Zoom', 'ZoomIn', 'ZoomOut', 'Pan', 'Reset'],
}
}
},
layers: [{
shapeData: usmap,
}]
});
map.appendTo('#element');Pinch zooming
To enable or disable the pinch zooming, use the pinchZooming property in zoomSettings.
import { usmap } from 'usa.ts';
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
zoomSettings: {
enable: true,
pinchZooming: true
},
layers: [{
shapeData: usmap,
}]
});
map.appendTo('#element');Single-click zooming
To enable or disable the single-click zooming, use the zoomOnClick property in zoomSettings.
import { usmap } from 'usa.ts';
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
zoomSettings: {
enable: true,
zoomOnClick: true
},
layers: [{
shapeData: usmap,
}]
});
map.appendTo('#element');Double-click zooming
To enable or disable the double-click zooming, use the doubleClickZoom property in zoomSettings.
import { usmap } from 'usa.ts';
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
zoomSettings: {
enable: true,
doubleClickZoom: true
},
layers: [{
shapeData: usmap,
}]
});
map.appendTo('#element');Mouse wheel zooming
To enable or disable mouse wheel zooming, use the mouseWheelZoom property in zoomSettings.
import { usmap } from 'usa.ts';
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
zoomSettings: {
enable: true,
mouseWheelZoom: true
},
layers: [{
shapeData: usmap,
}]
});
map.appendTo('#element');Selection zooming
To enable or disable selection zooming, use the enableSelectionZooming property in zoomSettings. The enablePanning property must be set to false to enable the selection zooming in Maps.
import { usmap } from 'usa.ts';
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
zoomSettings: {
enable: true,
enableSelectionZooming: true,
enablePanning: false
},
layers: [{
shapeData: usmap,
}]
});
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.
import { usmap } from 'usa.ts';
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
zoomSettings: {
enable: true,
minZoom: 2,
maxZoom: 12
},
layers: [{
shapeData: usmap,
}]
});
map.appendTo('#element');Zooming with animation
To zoom in or zoom out the Maps with animation, use the animationDuration property in layers.
import { usmap } from 'usa.ts';
import { Maps, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
zoomSettings: {
enable: true,
},
layers: [{
shapeData: usmap,
animationDuration: 500
}]
});

-
border- To customize the color, width and opacity of the border of which element is highlighted in Maps. -
fill- Applies the color for the element that is highlighted. -
opacity- To customize the transparency for the element that is highlighted.
Hovering on the specific legend, the shapes which are bounded to the selected legend is also highlighted and vice versa.

On mouse over or touch end event, the tooltip is used to get more information about the layer, bubble, or marker. To enable tooltip in Maps, the Tooltip module must be injected into Maps using Maps.Inject(Tooltip) method. 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 dataSource 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.
- MouseMove
- Click
- DoubleClick

</html>Changing duration in mobile devices
To change the duration of the tooltips and tooltip templates in mobile devices, you can use the duration property in tooltipSettings. By default, this property is set to 2000 milliseconds. Setting the value to 0 will keep the tooltip visible indefinitely. If it is greater than 0, the tooltip will be removed after the specified time.
import { world_map } from './world-map.ts';
import { Maps, MapsTooltip, ITooltipRenderEventArgs } from '@syncfusion/ej2-maps';
Maps.Inject(MapsTooltip);
let map: Maps = new Maps({
layers: [{
shapeData: world_map,
tooltipSettings: {
visible: true,
valuePath: 'name',
fill: '#D0D0D0',
textStyle: {
color: 'green',
fontFamily: 'Times New Roman',
fontStyle: 'Sans-serif'
},
duration: 3000
}
}]
});
