jQuery Geo

After years of internal development, we are pleased to bring our JavaScript map widget and spatial analysis tools to the open-source world in the form of a jQuery plugin.

Getting Started

Using jQuery Geo requires adding one element, including one script (apart from jQuery itself) and calling one function. The following copy-and-paste snippet will help you get started.

<div id="map" style="height: 320px;"></div>
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://code.jquerygeo.com/jquery.geo-1.0a4.min.js"></script>
<script>
  $(function() {
    $( "#map" ).geomap( ); // you've got a map!
  });
</script>

You can also download the latest release as a minified JavaScript file or a full, uncompressed one.

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using grunt.
