/*
*  How to build a Google Map and bind a SearchControl to it and put markers
*  on the map for each result we receive.
*/

// First, we have to load the APIs.
google.load('maps' , '2');
google.load('search' , '1');

// Global variables we will set in OnLoad
var map;
var searcher;

// Second, we set up our function, OnLoad
function OnLoad() {
  // Get the content div and clear it's current contents.
  var contentDiv = document.getElementById('content');
  contentDiv.innerHTML = ''; // Clear any content currently in the Div

  // Next thing we have to do is build two divs to hold our stuff
  var mapContainer = document.createElement('div'); // build the map div
  mapContainer.style.height = '350px'; // set the map height
  mapContainer.style.width = '350px'; // set the map width

  var controlContainer = document.createElement('div'); // build the control div
  controlContainer.style.width = '350px'; // set the control width

  // Now we have to add these divs to the content div in the document body
  contentDiv.appendChild(mapContainer);
  //contentDiv.appendChild(controlContainer);

  // We're ready to build our map...
  map = new google.maps.Map2(mapContainer);

  // ...and add a couple of controls.
  map.addControl(new google.maps.SmallMapControl()); // Add a small map control
  map.addControl(new google.maps.MapTypeControl()); // Add the map type control

  // We'll wait to the end to actually initialize the map
  // So let's build the search control
  var searchControl = new google.search.SearchControl();

  // Initialize a LocalSearch instance
  searcher = new google.search.LocalSearch(); // create the object
  searcher.setCenterPoint(map); // bind the searcher to the map

  // Create a SearcherOptions object to ensure we can see all results
  var options = new google.search.SearcherOptions(); // create the object
  options.setExpandMode(google.search.SearchControl.EXPAND_MODE_OPEN);

  // Add the searcher to the SearchControl
  searchControl.addSearcher(searcher , options);

 // And second, we need is a search complete callback!
  searchControl.setSearchCompleteCallback(searcher , function() {
    map.clearOverlays();
    var results = searcher.results; // Grab the results array
    // We loop through to get the points
    for (var i = 0; i < results.length; i++) {
      var result = results[i]; // Get the specific result
      var markerLatLng = new google.maps.LatLng(parseFloat(result.lat),
                                                parseFloat(result.lng));
      var marker = new google.maps.Marker(markerLatLng); // Create the marker

      // Bind information for the infoWindow aka the map marker popup
      marker.bindInfoWindow(result.html.cloneNode(true));
      result.marker = marker; // bind the marker to the result
      map.addOverlay(marker); // add the marker to the map
    }

    // Store where the map should be centered
    var center = searcher.resultViewport.center;

    // Calculate what the zoom level should be
    var ne = new google.maps.LatLng(searcher.resultViewport.ne.lat,
                                    searcher.resultViewport.ne.lng);
    var sw = new google.maps.LatLng(searcher.resultViewport.sw.lat,
                                    searcher.resultViewport.sw.lng);
    var bounds = new google.maps.LatLngBounds(sw, ne);
    var zoom = map.getBoundsZoomLevel(bounds, new google.maps.Size(350, 350));

    // Set the new center of the map
    // parseFloat converts the lat/lng from a string to a float, which is what
    // the LatLng constructor takes.
    map.setCenter(new google.maps.LatLng(parseFloat(center.lat),
                                         parseFloat(center.lng)),
                                         zoom);
  });

  // Draw the control
  searchControl.draw(controlContainer);

  // Set the map's center point and finish!
  map.setCenter(new google.maps.LatLng(37.443915 , -122.163610), 11);

 // Execute an initial search
  //searchControl.execute('pizza');
  setTimeout(function() {searchControl.execute(' near Berlin, Germany');}, 1000);
