Addons. MpJsApi

Addon, which provides a JavaScript API for the LGB Masterportal map viewer. If this addon is included to a LGB Masterportal map viewer a global object window.MpJsApi is injected to the window object of the browser page. The window.MpJsApi object offers the static JavaScript functions listed below. Ensure to call them without the Addons. prefix:

Example

const stateObj = MpJsApi.getMapViewerState();

Methods

staticAddons.MpJsApi.activateGFITool(){void}

addons/mpJsApi/src/marker.js, line 669
Activates the get feature info tool
Example
MpJsApi.activateGFITool()

staticAddons.MpJsApi.addResetButton(state, callback, targetSelector, btnOpts){Object}

addons/mpJsApi/src/resetButton.js, line 50
Adds a button to the MapViewer in order to reset the MapViewer state.

The MapViewer state object which will be applied on click has to be provided as first argument. The state object is mandatory, otherwise the function exits without rendering the button.
In order to apply a normal map state object AND a themed map ("Themenkarte") configuration you can pass in an array as first function parameter: [0 => normal map state, 1 => themed map conf].
On button click the provided callback function will be called with a notify function accepting a string argument, to use the application specific notification API. If no callback is defined, a no-op function will be called.
The default targetSelector is #root a. should be overwritten if the button should not be placed within the application menu.
The button options can be overwritten, e.g. to apply custom styles. Please note that we do not provide any translations, as they should be handled by the calling instance. The class property will be completely overwritten, so make sure that all required classes (e.g. Bootstrap button classes) will be set explicitly by the calling instance, when setting the btnOpts.class property.
Name Type Description
state Object | Array The state object or array with a state object and a themed map conf to be applied on click
callback function Callback function to be triggered onClick
targetSelector String Selector for the button target
btnOpts Object Object that contains the button options
Returns:

Example
// executing with map state object only
const stateObj = {extent: [353813, 5800182, 381488, 5813993], layers: []};
const resetCallback = (msg) => {msg("Zurückgesetzt")};

staticAddons.MpJsApi.addResetMenuEntry(state, callback, opts){Object}

addons/mpJsApi/src/resetButton.js, line 216
Adds a menu entry to the MapViewer's main menu in order to reset the MapViewer state.

Similar to the function Addons.MpJsApi.addResetButton but instead of adding a button markup this creates the correct markup to add an entry to the MapViewer's main menu.
The MapViewer state object will be applied on click and has to be provided as first argument. The state object is mandatory, otherwise the function exits without rendering the menu entry.
In order to apply a normal map state object AND a themed map ("Themenkarte") configuration you can pass in an array as first function parameter: [0 => normal map state, 1 => themed map conf].
By clicking the menu entry the provided callback function will be called with a notify function accepting a string argument, to use the application specific notification API. If no callback is defined, a no-op function will be called.
The markup options can be overwritten, e.g. to apply custom styles. Please note that we do not provide any translations, as they should be handled by the calling instance. The class property will be completely overwritten, so make sure that all required classes (e.g. Bootstrap classes) will be set explicitly by the calling instance, when setting the opts.class property.
Name Type Description
state Object | Array The state object or array with a state object and a themed map conf to be applied on click
callback function Callback function to be triggered on click
opts Object Object that contains the options

staticAddons.MpJsApi.addSaveButton(callback, targetSelector, btnOpts){Object}

addons/mpJsApi/src/saveButton.js, line 37
Adds a saveButton to the MapViewer.

On button click, the callback function will be called with an array holding the current MapViewerState (array index 0) and the current themed map configuration with the external layers (array index 1) as its first argument. The second argument is a notify function accepting a string argument, to use the application specific notification API. If no callback is defined, a no-op function will be called.
The default targetSelector is #root a. should be overwritten if the button should not be placed within the application menu.
