Update
Displaying a <div>
on top of a google map is straight forward :
example css:
div.info {
position: absolute;
z-index: 999;
width: 200px;
height: 100px;
display: none;
background-color: #fff;
border: 3px solid #ebebeb;
padding: 10px;
}
A info
class <div>
somewhere in the markup :
<div id="myinfo" class="info"><p>I am a div on top of a google map .. </p></div>
Always nice to have a short reference to the div :
var info = document.getElementById('myinfo');
The more tricky part, showing the <div>
, how and when - here I just assign a click handler to the map (after it is created) and show the info <div>
at mouse location XY inside the map :
google.maps.event.addListener(map, 'click', function(args) {
var x=args.pixel.x; //we clicked here
var y=args.pixel.y;
info.style.left=x+'px';
info.style.top=y+'px';
info.style.display='block';
});
What you gain with this is, that the info <div>
follows you around on the map, every time you click.
- You will need more styling so it suits your need, eg so it "looks like an InfoBox", but that should be easy to find out, I am not a librarian :)
- And maybe later on something to close the info with, but that you didn't want in the first place :)
Original answer
You cant! There is no way to do this in the current v3.13 InfoWindow options.
A workaround is to disable the image containing the X :
<style>
img[src="http://maps.gstatic.com/mapfiles/api-3/images/mapcnt3.png"] {
display: none;
}
</style>
But this is in no way advisable!
src="http://maps.gstatic.com/mapfiles/api-3/images/mapcnt3.png
is just what the infowindow is referring to today. Tomorrow, or in a month, or in a year, this image-reference for sure has changed. As you can see if you search for similar "solutions", made over time - like this. They are all broken today, eg the effort is meaningless.
I think there is extremely good logic in google "refusing" to follow the request for hiding the close-button. If you not need a close-button, what do you need an InfoWindow for anyway? When you are better off just to show a <div>
on the map.
<div>
on the map that looks like an InfoBox? – Penis
