Module Query

Process a query request to the JMap server, for given layer and query ids, and provided form data

throws

example

// returns a promise that when resolved returns the result of the search,
// an array of features, for layer id=3 and query id=5.
JMap.Query
  .fetchFeatures(3, 5, {
   "$PARAM1": "test",
   "$PARAM2": 35
  })
  .then(features => console.info(`Found ${features.length} features.`))
  .catch(error => console.error("Error while processing query request.", error))

JMap.Query.getAllGroups()

Returns all queries for a given query group id.

example

// returns all queries of group id=10
JMap.Query.getQueriesByGroupId(10)

Returns all queries defined for a given layer id.

throws

if layer id is not correct (invalid format or no resource exists)

example

// returns all queries of layer id=12
JMap.Query.getQueriesByLayerId(12)

Returns the query for a given query group and a given query id.

throws

example

// returns the query id=5 of group id=10
JMap.Query.getQueryByGroupId(10, 5)

Returns a query for a given query id, and a given layer id.

throws

if layer or query ids are not correct (invalid format or no resource exists)

example

// returns query id=3 of layer id=12
JMap.Query.getQueryByLayerId(12, 3)

Returns true if group exists, else false, for the given group id.

throws

if group id is not correct (invalid format or no resource exists)

example

// returns true if group exists
JMap.Query.groupExist(21)

By default attribute query forms are not fetched from server, because sometime it takes too much time.

This method will fetch the query form.

example

// initializes query id="layers/2/attribute-queries/3" form of layer id=2, then returns the filled query
JMap.Query.initializeQueryFormById(2, "layers/2/attribute-queries/3")
 .then(query => console.log("Query form has been loaded", query))
 .catch(error => console.error("An error occured while loading query id='layers/2/attribute-queries/3'"))

Returns true if the query exists for a given query group and a given query id.

example

// returns true if query id=5 of group id=10 exists
JMap.Query.queryExist(10, 5)
