How to add a GoogleMap Search Box to my customized map?


I'm developing my own map with google API and IGN API (french map) and I'd like to add a Google Map Search Box but can't find a way to succeed even after reading carefully the Google Map API.

This is what I have: http://www.tiphainebuccino.com/site/Map/LaCarteAuxTresors_2.html

This is what I want to add (without losing my actual settings): https://developers.google.com/maps/documentation/javascript/examples/places-searchbox?hl=fr

I don't understand how to mix the two html codes. Someone could help me? I work in html+javascript.

The relevant (non-working) code:

    var ignKey = "ljozkgwvms60dtumhx67z6u3"

    function makeIGNMapType(layer, name, maxZoom) {
        return new google.maps.ImageMapType({

Solution

  • I get this error on your map:

    Uncaught TypeError: Cannot read property 'SearchBox' of undefined 
    

    You need to include the places library when you load the API.

    Change:

    <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
    

    To:

    <script type="text/javascript" src="http://maps.google.com/maps/api/js?libraries=places&sensor=false"></script>
    

    You also don't have an element with id="pac-input" on your page. Add this to your HTML markup:

    <input id="pac-input"></input>
    

    Working example

    code snippet (with moon tiles as the originals are no longer available):

    var ignKey = "ljozkgwvms60dtumhx67z6u3"
    var markers = [];
    
    function makeIGNMapType(layer, name, maxZoom) {
      return new google.maps.ImageMapType({
