Fusion Table Layers

JS:
var initial = document.getElementById('address').value;//initial value is zip codes separated by commas and no space between:: example:40475,40489,44456
$.ajax({
type:"GET",
url: "query.php?zipcode="+encodeURI(initial),
dataType: 'json',
success: function(data) {
map.data.forEach(function (feature) {
map.data.remove(feature);
});
map.data.loadGeoJson('google.json');
map.data.addGeoJson(data);
map.data.setStyle({
icon: '//example.com/path/to/image.png',
fillColor: "#FF0000",
strokeColor: "#FF0000",
fillOpacity: 0.2,
strokeOpacity: 0.6,
strokeWeight: 3
});
}
});
