General

When publishing maps via portal pages in the WebGIS Portal, there is no direct access to the source code of the individual maps. To still make adjustments, a custom.js file can be used. This file should be located in the directory portal5/scripts/portals/{url-id-des-portals}. During installation, such a file already exists under portal5/scripts/portals/eni.

Note

The viewer automatically loads this file every time a map is started. If it does not exist, this has no effect, but it can lead to log entries on the server. It is therefore advisable to at least keep an empty file with this name in place.

Since the file is included on every viewer call, it is suitable for overriding API values, e.g. for markers or custom tools.

Tip

The methods shown here apply to all maps of a portal page. If a method should only be active for specific maps, this can be controlled via a condition.

The variable mapUrlName contains the name of the currently loaded map and can be used to restrict behavior to specific maps.

Example:

Adding a custom tool only for the map “Geoland”:

if (mapUrlName === "Geoland") {
    webgis.custom.tools.add({
        name: 'Super Tool',
        command: 'https://www.google.com/maps/@{y},{x},19z'
    });
}
