Layer Attribute Events

FeatureRowClicked​

Description​

The FeatureRowClicked event is triggered when a user clicks on a feature row within a layer attribute table on a map using the Maptaskr for Power Pages App. This event provides information about the clicked feature's ID and geometry.

Usage​

To listen for the FeatureRowClicked event, you can use the on method of the window['maptaskrPCF'] object. This allows you to register an event listener that executes a call-back function when the event is triggered.

Example​

window['maptaskrPCF'].on("FeatureRowClicked", function(id, geometry) { 
    
    console.log("id: " + id);

    console.log(" geometry: " + geometry);

});

In the example above, we've registered an event listener for the FeatureRowClicked event. The provided call-back function is executed when the event occurs, logging the clicked feature's ID and geometry to the console.

Parameters​

  • id (string): The ID of the clicked feature.
  • geometry (string): The geometry information of the clicked feature.

Response Example​

The geometry returned will be a JavaScript Object in the format provided below (with some properties excluded for brevity)

{

    " paths": [ 
        [ 
            [ 152.951965843402, -27.559003020827 ], 
            [ 152.952433438347, -27.5590516415601 ] 
        ] 
    ] 
}

Removing Event Listeners​

To remove the event listener for the FeatureRowClicked event, you can use the off method of the window['maptaskrPCF'] object. This is useful when you no longer want to listen to this specific event.

Example​

window['maptaskrPCF'].off("FeatureRowClicked");

In the example above, the event listener for FeatureRowClicked is removed, ensuring that the associated call-back function no longer executes when the event is triggered.

FeatureRowsSelected​

Description​

The FeatureRowsSelected event is triggered when a user selects one or more feature rows within a layer attribute table on a map using the Maptaskr for Power Pages App. This event provides information about the selected feature's ID.

Usage​

To listen for the FeatureRowsSelected event, you can use the on method of the window['maptaskrPCF'] object. This allows you to register an event listener that executes a call-back function when the event is triggered.

Example​

window['maptaskrPCF'].on("FeatureRowsSelected", function(id, checked) { 
    
    console.log("id: " + id);

    console.log(" checked: " + checked);

});

In the example above, we've registered an event listener for the FeatureRowsSelected event. When the event occurs, the provided call-back function is executed, logging the ID of the selected feature to the console.

Parameters​

  • id (string): The ID of the selected feature.
  • checked (boolean): If the feature is checked or unchecked.

Removing Event Listeners​

To remove the event listener for the FeatureRowsSelected event, you can use the off method of the window['maptaskrPCF'] object. This is useful when you no longer want to listen to this specific event.

Example​

window['maptaskrPCF'].off(" FeatureRowsSelected");

In the example above, the event listener for FeatureRowsSelected is removed, ensuring that the associated call-back function no longer executes when the event is triggered.

SelectedFeaturesHighlightedOnMap​

Description​

The SelectedFeaturesHighlightedOnMap event is triggered when selected features are highlighted on the map using the Maptaskr for Power Pages App. This event provides information about the highlighted feature's ID and geometry.

Usage​

To listen for the SelectedFeaturesHighlightedOnMap event, you can use the on method of the window['maptaskrPCF'] object. This allows you to register an event listener that executes a call-back function when the event is triggered.

Example​

window['maptaskrPCF'].on("SelectedFeaturesHighlightedOnMap", function(id, geometry) {
    
    console.log("id: " + id);

    console.log(" geometry: " + geometry);

});

In the example above, we've registered an event listener for the SelectedFeaturesHighlightedOnMap event. The provided call-back function is executed when the event occurs, logging the highlighted feature's ID and geometry to the console.

Parameters​

  • id (string): The ID of the highlighted feature.
  • geometry (string): The geometry information of the highlighted feature.

Response Example​

The geometry returned will be a JavaScript Object in the format provided below (with some properties excluded for brevity)
