I am trying a very simple exercise to display a google map on visualforce page. But nothing is showing up.

Below is my page code -

<apex:page controller="SampleLocation">

    <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
    <style type="text/css">
      html { height: 100% }
      body { height: 100%; margin: 0; padding: 0 }
      #map-canvas { height: 100% }
    <script type="text/javascript"
    <script type="text/javascript">
      function initialize() {
        var mapOptions = {
          center: new google.maps.LatLng(-34.397, 150.644),
          zoom: 8
        var map = new google.maps.Map(document.getElementById("map-canvas"),
      google.maps.event.addDomListener(window, 'load', initialize);
    <div id="map-canvas"/>


Below is console log

Below is Network log,

when I preview the page, nothing is shown.

when I save the exact same code in separate html file ( after removing apex:page tag) the code works just fine. I am sure that there is no issue with the API key.

any idea what is going wrong here ?

  • I suggest in future you post your code as text (and use the {} to format it). That way people can take and run an exact copy to try to help you.

When I use your code with the div set to a hard-coded size:

<div id="map-canvas" style="width: 500px; height: 500px"/>

the map renders.

Remember that your Visualforce page includes a lot of Salesforce CSS and the header and sidebar HTML (that are not present if you just strip out the content into a html file). So you will need to figure out the appropriate CSS styling to apply to get the result you want.

  • it worked, Thx!!
