Custom controls

This example creates a map with a "Center Map" button, which will pan the map to be centered on Chicago.

Read the documentation or view this example full screen.

var map;
var chicago = {lat: 41.85, lng: -87.65};

/**
 * The CenterControl adds a control to the map that recenters the map on
 * Chicago.
 * This constructor takes the control DIV as an argument.
 * @constructor
 */
function CenterControl(controlDiv, map) {

  // Set CSS for the control border.
  var controlUI = document.createElement('div');
  controlUI.style.backgroundColor = '#fff';
  controlUI.style.border = '2px solid #fff';
  controlUI.style.borderRadius = '3px';
  controlUI.style.boxShadow = '0 2px 6px rgba(0,0,0,.3)';
  controlUI.style.cursor = 'pointer';
  controlUI.style.marginBottom = '22px';
  controlUI.style.textAlign = 'center';
  controlUI.title = 'Click to recenter the map';
  controlDiv.appendChild(controlUI);

  // Set CSS for the control interior.
  var controlText = document.createElement('div');
  controlText.style.color = 'rgb(25,25,25)';
  controlText.style.fontFamily = 'Roboto,Arial,sans-serif';
  controlText.style.fontSize = '16px';
  controlText.style.lineHeight = '38px';
  controlText.style.paddingLeft = '5px';
  controlText.style.paddingRight = '5px';
  controlText.innerHTML = 'Center Map';
  controlUI.appendChild(controlText);

  // Setup the click event listeners: simply set the map to Chicago.
  controlUI.addEventListener('click', function() {
    map.setCenter(chicago);
  });

}

function initMap() {
  map = new google.maps.Map(document.getElementById('map'), {

  centerControlDiv.index = 1;
  map.controls[google.maps.ControlPosition.TOP_CENTER].push(centerControlDiv);
}
