Oh my god. It's full of code!

Google Maps in jQuery UI Dialog

Just a quick fix type of post that hopefully someone finds in their googling. If you are attempting to use a google map (either v2 or v3) in your page, and want it inside a jQuery UI dialog box, you will likely run into a strange behavior where half the map is grey. You can pan around, zoom and such, but the map itself just acts weird. Only chunks of it show up. The reason for this, as close as I can find is that the map figured out how large it can be by finding the size of it’s parent container. So when you make a dialog box that isn’t autoopen it has no size. So the map says ‘ok, I guess I don’t really have a size’ and it proceeds to freak out. The fix is super simple, but it took me way to long to find and properly implement.

First of all, check out a demo Here

Then check out the source

    coords.lng = -93.242539;
        $( "#map_container" ).dialog({
            width: 555,
            height: 400,
            resizeStop: function(event, ui) {google.maps.event.trigger(map, 'resize')  },
            open: function(event, ui) {google.maps.event.trigger(map, 'resize'); }      

        $( "#showMap" ).click(function() {           
            $( "#map_container" ).dialog( "open" );
            map.setCenter(new google.maps.LatLng(coords.lat, coords.lng), 10);
            return false;
        $(  "input:submit,input:button, a, button", "#controls" ).button();
        plotPoint(coords.lat,coords.lng,'Mall of America','<span class="gBubble"><b>Mall of America</b><br>60 East Brodway<br>Bloomington, MN 55425</span>');

    function plotPoint(srcLat,srcLon,title,popUpContent,markerIcon)
            var myLatlng = new google.maps.LatLng(srcLat, srcLon);            
            var marker = new google.maps.Marker({
                  position: myLatlng, 
                  map: map, 
                  icon: markerIcon
            var infowindow = new google.maps.InfoWindow({
                content: popUpContent
              google.maps.event.addListener(marker, 'click', function() {
    function initialize() 
        var latlng = new google.maps.LatLng(coords.lat, coords.lng);
        var myOptions = {
          zoom: 10,
          center: latlng,
          mapTypeId: google.maps.MapTypeId.ROADMAP
       map = new google.maps.Map(document.getElementById("map_canvas"),  myOptions);                         

    <div id="map_container" title="Location Map">    
        <div id="map_canvas" style="width:100%;height:100%;"></div>
    <div id="controls">
        <input type="button" name="showMap" value="Show Map" id="showMap" />

The secret is the event handlers for the open and resize actions on the dialog.

            resizeStop: function(event, ui) {google.maps.event.trigger(map, 'resize')  },
            open: function(event, ui) {google.maps.event.trigger(map, 'resize'); } 

Those guys right there make the magic happen. Just make sure to include the resize functions in the event handlers when you register the dialog and you are all good. They just say when the dialog is opened or resize, have the google map recheck the size of it’s parent and scale accordingly. That resolves the issue in a snap. The rest of the code just makes a nice little sample app you can play with. Anyway, I really hope this helps someone cause I spent an afternoon beating my head against the wall on this one, and even migrated my whole app from google maps v2 to v3 hoping that would fix it, when it didn’t >.<

    Thank for your post. The most elegant solution I have found:
    While your example works like a chime in my case I have problems loading the map when I use Firefox 3.6. I get the map only partially loaded in the right top corner and the error is:
    Error : a is undefined
    File Source : http://maps.gstatic.com/intl/fr_ALL/mapfiles/api-3/8/1/main.js
    Line : 19

    Do you have any ideas why this happens?

    What about calling initialize(); in the open function of the dialog instead of in the $(document).ready(function() ?
    This is what I have and it works for me.

    October 24, 2012 at 3:26 am

    • That’s a pretty good idea as well. In this case it would probably work, but I figure initializing the map before the user needs it may speed up performance. Then just resizing it as needed. I have no idea if that actually makes a difference or not, just my thought process.

    Hey just wondering if I could replace the 1.6.2-jquery.min.js file with latest version of jquery js? Cuz after replacing the file, the map stop loading halfway and also the window is not at the center of screen..

    November 1, 2012 at 4:14 am

    • Hm, make sure you use the newest jQuery UI js and css sheets as well. It should work fine.

      November 1, 2012 at 4:50 am

    Thanks for this article.

    I want to pass the latitude and longitude dynamically.
    or how can i pass latitude and longitude with showMap button?

    Any help would be appreciated? Thanks!

    August 14, 2013 at 6:58 pm

    • This sample code should do it for ya. I just added some form fields, bound their data to the submit button and rigged the map to draw the point based on the data it gets passed in.
