fusiontips

Forked from Google Code to enable usage with the Fusion Tables v1 API.

This library allows MapTip and fires mouseover/mouseout event for FusionTableLayers. It uses mouse cursor tracking and pause delay to trigger FusionTableQuery. It is not true mouseover event, but should suit most use cases.

Usage

Include Scripts

This library enables map tips and mouseover/mouseout for FusionTablesLayer The first step is to include fusiontips.js in your document header, after GMaps API is load. You can use the online version if you do not want to download the script.

<script src="/path/to/fusiontips.js" type="text/javascript"></script>

Enable Map tips

You can simply call google.maps.FusionTablesLayer.enableMapTips(options) to enable it.

function init(){
  var tableid = 297050;
  var googleApiKey = "xxxxxx"; //get yours at https://code.google.com/apis/console/
  layer = new google.maps.FusionTablesLayer({
    query: {
      select: 'Address',
      from: tableid
    },
    map: map
  });
  layer.enableMapTips({
    select: "'Store Name','Address'", // list of columns to query, typially need only one column.
    from: tableid, // fusion table name
    geometryColumn: 'Address', // geometry column name
    suppressMapTips: false, // optional, whether to show map tips. default false
    delay: 200, // milliseconds mouse pause before send a server query. default 300.
    tolerance: 8, // tolerance in pixel around mouse. default is 6.
    googleApiKey: googleApiKey,
    htmlTemplate: function(rows) {
        return 'Details: <b>My Column1: </b>' + rows[0][0] + '<br><b>My Column2: </b>'+rows[0][1];
      } 
  });
  //listen to events if desired.
  google.maps.event.addListener(layer, 'mouseover', function(fEvent) {
    var row = fEvent.row;
    myHtml = 'mouseover:<br/>';
    for (var x in row) {
      if (row.hasOwnProperty(x)) {
        myHtml += '<b>' + x + "</b>:" + row[x].value + "<br/>";
      }
    }
    document.getElementById('info').innerHTML = myHtml;
  });
  google.maps.event.addListener(layer, 'mouseout', function(fevt) {
    document.getElementById('info').innerHTML = '';
  });
}
