Integration example

You can include openlayers in a Plone browser page in this way (for further information about openlayers see other openlayers examples):

<html xmlns=""
    <metal:block metal:fill-slot="javascript_head_slot">
      <script type="text/javascript">
          (function ($) {
            var map;
            $(window).load(function() {
              map = new OpenLayers.Map('map',{
                theme: null
              map.addLayer(new OpenLayers.Layer.OSM("OpenStreetMap"));
              map.setCenter(new OpenLayers.LonLat(7, 45).transform(
                  new OpenLayers.Projection("EPSG:4326"),
              ), 5);

        // -->
    <metal:content fill-slot="content-core">
        <metal:content define-macro="content-core">
          <div id="map" class="olMap widget-cgmap">
            <!-- openlayers map -->

Updating this package

When a new version of OpenLayers is released, the javascript on this package can be updated by using the Makefile in the root directory. Commands available:

  • build - it builds a new version of OpenLayer javascript.

  • copysrc - it copies all necessary files in plone resources directory.

  • dist - it is the default command, it executes all previous commands.
