If you are looking to display templatized, pre-rendered ads for mobile applications (native or web), see the Mobile Ads API. If you are interested in obtaining ad data which you then render on your own, see the Custom Ads API.

Obtaining Web Ads

To enable the display of ads, you must include the CityGrid loader script in the page:

...

To obtain the actual ad, invoke the CityGrid.Ads constructor with two arguments: the id of the div element that wraps the ad unit, and a JavaScript object that holds the ad parameters.

Code Block
<script type="text/javascript"> new CityGrid.Ads(containerDiv, callParameters); </script>

The ad image will be rendered into your div. The following example adds an ad to a div with the id of sidebar_ad_slot, and ad parameters that specify an ad relevant for sushi and a given longitude and latitude:

Code Block


<div id="sidebar_ad_slot"></div>
<script type="text/javascript" src="http://static.citygridmedia.com/ads/scripts/v2/loader.js"></script>
<script type="text/javascript">
  new CityGrid.Ads('sidebar_ad_slot', {
    collection_id: 'web-001-630x100',
    publisher: 'citysearch',
    what: 'sushi',
    where: '90069',
    lat: 34.088188,
    lon: -118.37205,
    width: 630,
    height: 100
  });
</script>
