    Parameters

    • layerId: JId

      The JMap layer id

    Example

    // returns all features attributes for layer 4
    JMap.Map.getRenderedFeaturesAttributeValues(4)

    // returns all features attributes for layer 4, that intersect the location
    JMap.Map.getRenderedFeaturesAttributeValues(4, { x: 45.54, y: 65.43 })

    // returns all features attributes for layer 4, that intersect the circle (radius in km)
    JMap.Map.getRenderedFeaturesAttributeValues(4, { center: { x: 45.54, y: 65.43 }, radius: .5 })

    // returns all features attributes for layer 4, that intersect the boundary box
    JMap.Map.getRenderedFeaturesAttributeValues(4, { sw: { x: 45.54, y: 65.43 }, ne: { x: 48.54, y: 70.43 }})

    // Example of result for features that have only 2 attributes "Firestation" and "Nursery" :
    [
     { name: "Firestation", age: 23, featureId: 2377 },
     { name: "Nursery", age: 20, featureId: 3456 }
    ]
