Adding and removing controls on Google Maps in real-time

Recently, I encountered an issue with my custom search bar overlapping some controls on my map. Despite adjusting the z-index of these controls, they continued to stay on top. To work around this problem, I thought about hiding the controls during the search process. However, I couldn't find a way to dynamically remove or hide them.

Does anyone have a creative solution for this dilemma? Whether it involves adding and removing the controls, hiding them temporarily, or properly adjusting their z-index, any suggestions would be appreciated.

Answer №1

Utilize the setOptions method to dynamically change the map's configuration (comprehensive documentation for Google Maps JavaScript API V3 can be found here)

// initialization of the map
var myLatlng = new google.maps.LatLng(-33, 151);
var myOptions = {
  center: myLatlng,
  zoom: 5,
  streetViewControl: false,
  zoomControl: false,
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

// functions for toggling controls dynamically
function toggleMapTypeControl(b) {
  map.setOptions({
    mapTypeControl: b
  });
}

function toggleStreetViewControl(b) {
  map.setOptions({
    streetViewControl: b
  });
}

function toggleZoomControl(b) {
  map.setOptions({
    zoomControl: b
  });
}

#map_canvas {
  width: 50%;
  height: 200px;
  float: left;
}

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>
<div id="map_canvas"></div>
<input type="checkbox" onclick="toggleMapTypeControl(this.checked)" />mapTypeControl
<br>
<input type="checkbox" onclick="toggleStreetViewControl(this.checked)" />streetViewControl
<br>
<input type="checkbox" onclick="toggleZoomControl(this.checked)" />zoomControl

Initially, I tried setting z-index: 999999 on the container I wanted to bring to the front, but after numerous attempts and online searches, I couldn't make it work.

It appears that whenever an element is added to the map, its z-index is reset to 0. Despite several failed attempts, I couldn't figure out how to maintain the desired css z-index value for the map. In the end, my workaround was to set the z-index value after adding it to the map:

$('#element_id').css('z-index', 10);

While not as elegant as I had hoped, this approach did the trick since the z-index reset had already occurred.
