This event is triggered when a layer dynamic filter is activated or deactivated.

example

// Each time a layer dynamic filter is activated or deactivated, will display a message in the console
JMap.Event.Layer.on.dynamicFilterActivationChange(
   "custom-layer-dynamic-filter-activation-changed",
   params => {
     console.info(`The dynamic filter of layer id=${params.layerId} has been ${params.isActivation ? "activated" : "deactivated"}`)
   }
)

This event is triggered when a condition is created on a layer dynamic filter.

example

// Each time a condition is created on a layer dynamic filter, will display a message in the console
JMap.Event.Layer.on.dynamicFilterConditionCreated(
   "custom-layer-dynamic-filter-condition-created",
   params => {
     console.info(`Condition added on layer id=${params.layerId}'s dynamic filter`, params.filter, params.condition)
   }
)

This event is triggered when a condition is updated on a layer dynamic filter.

example

// Each time a condition is updated on a layer dynamic filter, will display a message in the console
JMap.Event.Layer.on.dynamicFilterConditionUpdated(
   "custom-layer-dynamic-filter-condition-updated",
   params => {
     console.info(`Condition updated on layer id=${params.layerId}'s dynamic filter`, params.filter, params.condition)
   }
)

This event is triggered when a condition is removed on a layer dynamic filter.

example

// Each time one or more conditions are removed for a layer dynamic filter, will display a message in the console
JMap.Event.Layer.on.dynamicFilterConditionsRemoved(
   "custom-layer-dynamic-filter-conditions-removed",
   params => {
     console.info(`Condition(s) removed on layer id=${params.layerId}'s dynamic filter`, params.filter, params.conditionIds)
   }
)

This event is triggered when some dynamic filters are set.

Could happen when a map context is applied, or when we use the method JMap.Layer.DynamicFilter.set.

example

// Each time some layer dynamic filters have been set
JMap.Event.Layer.on.dynamicFilterSet(
   "custom-layer-dynamic-filter-set",
   params => console.info("Some dynamic filters have been set", params)
)

This event is triggered when the initial layer search is applied (if exist).

example

// Each time the initial search is applied, will display a message in the console
JMap.Event.Layer.on.initialSearchApplied(
   "custom-layer-initial-search-applied",
   params => {
     console.info(`Initial search on layer id="${params.layerId}" has been applied`, params.features)
   }
)

This event is triggered when a layer is deleted.

example

// Each time a layer is deleted, will display a message in the console
JMap.Event.Layer.on.layerDeletion(
   "custom-layer-deletion",
   params => {
     console.log(`Layer id="${params.layerId}" has been deleted client side`)
   }
)

This event is triggered when a new project has been loaded, and when its layers have been loaded too.

If the project has been unloaded, this event is triggered but the provided layerTree is an empty array (in JMap a project has at least one layer).

example

// Each time a new project is loaded and its layer have also been loaded,
// this method is processed.
JMap.Event.Layer.on.layersChange(
   "custom-layers-change",
   params => {
     console.log("This is the new project layer three", params.layerTree)
   }
)

This event is triggered just before a vector layer selectability is changed. This permits to act on selection before the layer selectability property is effectively changed

example

// Each time a vector layer selectability will change, it will display the next selectability
// in the console
JMap.Event.Layer.on.selectabilityWillChange(
   "custom-selectability-will-change",
   params => {
     console.log(`Vector layer id="${params.layerId}" next selectability="${params.selectability}"`)
   }
)

This event is triggered when a layer's source has changed (for instance after modifying, adding or deleting a feature).

example

// Each time a layer's source has changed, it will display a message
// in the console
JMap.Event.Layer.on.sourceChange(
   "custom-source-change",
   params => {
     console.log(`Source for layer id="${params.layerId}" has changed"`)
   }
)

This event is triggered when the visibility state of a layer thematic categories changes.

example

// Each time a layer thematic category visibility state is changed this method is processed
JMap.Event.Layer.on.thematicCategoriesVisibilityChange(
   "custom-thematic-categories-visibility-change",
   params => {
     console.log(
       `Layer id="${params.layerId}", ` +
       `thematic id="${params.thematicId}" ` +
       `hidden categories="${params.hiddenCategoryIndexes.toString()}"`
     )
   }
)

This event is triggered when the visibility state of a layer thematic condition changes.

It works only for JMap Cloud server, for style rule thematics.

example

// Each time a layer thematic condition visibility state is changed this method is processed
JMap.Event.Layer.on.thematicConditionsVisibilityChange(
   "custom-thematic-conditions-visibility-change",
   params => {
     console.log(
       `Layer id="${params.layerId}", ` +
       `thematic id="${params.thematicId}" ` +
       `hidden conditions="${params.hiddenConditionIds.toString()}"`
     )
   }
)

This event is triggered when a layer thematic visibility changed.

example

// Each time a layer thematic visibility is changed this method is processed
JMap.Event.Layer.on.thematicVisibilityChange(
   "custom-thematic-visibility-change",
   params => {
     console.log(
       `Layer id="${params.layerId}", ` +
       `thematic id="${params.thematicId}" ` +
       `visible="${params.visibility}"`
     )
   }
)

This event is triggered when a tree element visibility changed.

example

// Each time a tree element visibility is changed, will display the new visibility
// in the console
JMap.Event.Layer.on.visibilityChange(
   "custom-visibility-change",
   params => {
     console.log(`Layer element id="${params.layerId}" visible="${params.visibility}"`)
   }
)
