Get Google Maps v3 to resize height of InfoWindow

Question

When I click a marker and the InfoWindow appears, the height does not adjust if the length of the content is longer that the InfoWindow default height (90px).

• I am using text-only, no images.
• I have tried maxWidth.
• I have checked for inherited CSS.
• I have wrapped my content in a div and applied my CSS to that, including a height.
• I have even tried forcing the InfoWindow to resize with jQuery using the domready event on the InfoWindow.

I only have a few hairs left. Here is my JS:

var geocoder;
var map;
var marker;

function initialize() {
  geocoder   = new google.maps.Geocoder();
  var latlng = new google.maps.LatLng(41.8801,-87.6272); 
  var myOptions = {
    zoom: 13,
    center: latlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}

function codeAddress(infotext,address) {
  geocoder.geocode({ 'address': address }, function (results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      map.setCenter(results[0].geometry.location);
      var image  = '/path-to/mapMarker.png';
      var infowindow = new google.maps.InfoWindow({ content: infotext, maxWidth: 200 });
      var marker = new google.maps.Marker({
        map: map,
        position: results[0].geometry.location,
        icon: image
      });
      google.maps.event.addListener(marker, 'click', function () { 
        infowindow.open(map, marker); 
      });
    }
  });

}

function checkZipcode(reqZip) {

  if ( /[0-9]{5}/.test(reqZip) ) {

    $.ajax({
      url: 'data.aspx?zip=' + reqZip,
      dataType: 'json',
      success: function(results) {

        $.each(results.products.product, function() {

          var display = "<span id='bubble-marker'><strong>"+this.name+"</strong><br>"+
                        this.address+"<br>"+
                        this.city+", "+this.state+" "+this.zip+"<br>"+
                        this.phone+"</span>";

          var address = this.address+","+
                        this.city+","+
                        this.state+","+
                        this.zip;

          codeAddress(display,address);

        });

      },
      error: function() { $('#information-bar').text('fail'); }
    });

  } else { $('#information-bar').text('Zip codes are five digit numbers.'); }

}

$('#check-zip').click(function() { $('#information-bar').text(''); checkZipcode($('#requested-zipcode').val()); });

initialize();

InfoText and Address come from an AJAX query of an XML file. Data is not the issue, as it always comes through correctly. codeAddress() is called after the data has been retrieved and formatted.

HTML in the file:

<div id="google_map"> <div id="map_canvas" style="width:279px; height:178px"></div> </div>

CSS for my InfoWindow content (no other CSS applies to the map):

#bubble-marker{ font-size:11px; line-height:15px; }

I finally found a working solution for the problem. Is not as flexible as I wished, but it's pretty good. Fundamentally the key point is: don't use a string as window content but instead a DOM node. This is my code:

// this dom node will act as wrapper for our content
var wrapper = document.createElement("div");

// inject markup into the wrapper
wrapper.innerHTML = myMethodToGetMarkup();

// style containing overflow declarations
wrapper.className = "map-popup";

// fixed height only :P
wrapper.style.height = "60px";

// initialize the window using wrapper node     
var popup = new google.maps.InfoWindow({content: wrapper});

// open the window
popup.open(map, instance);

the following is the CSS declaration:

div.map-popup {
    overflow: auto;
    overflow-x: hidden;
    overflow-y: auto;
}

ps: "instance" refers to the current custom subclass of google.maps.OverlayView (which I'm extending)

Just wrap your content with a div and specify it's height: <div style="height:60px">...</div>, e.g.

 myMarker.setContent('<div style="height:60px">' + txt + '</div>');

- In my case it was fairly enough.
