marker-query

Version compatibility

marker-query was introduced in version 4.82.0 of the JourneyApps Runtime.

Overview

marker-query is almost identical to marker. It differs in that the markers can be populated on the map using a query.

Basic Example

Below is an example of using capture-coordinates along with a marker-query.

schema.xml

<model name="user" label="User">
    <field name="name" label="Name" type="text:name"/>
    <field name="location" label="Location" type="location"/>
    <display>{name} - {location}</display>
</model>

main.view.xml

<var name="current_location" type="location" />
<var name="users" type="query:user" />

<capture-coordinates bind="current_location">
    <marker-query query="users" latitude="{location.latitude}" longitude="{location.longitude}" label="{name}" />
</capture-coordinates>

main.js

function init() {
    view.users = DB.user.where('location != ?', null);
}

Below is an example of using display-coordinates along with multiple query markers.

schema.xml

<model name="user" label="User">
  <field name="name" label="Name" type="text:name"/>
  <field name="location" label="Location" type="location"/>
  <display>{name} - {location}</display>
</model>

main.view.xml

<var name="map_center" type="location" />
<var name="users" type="query:user" />

<display-coordinates bind="map_center">
    <marker-query query="users" latitude="{location.latitude}" longitude="{location.longitude}" label="{name}" />
</display-coordinates>

main.js

function init() {
  view.map_center = journey.hardware.getCurrentLocation();
  view.users = DB.user.where('location != ?', null);
}
