So, my question is - I have a small map on my page and I want open this map in a full screen on the same page by pressing a button and close it in the same way. I think it can be done by removing div styles when you press the button but I didn't succeed, may be this is a wrong way? I understand that is a simple question but my google skills aren't well developed and I just don't know how to ask this question properly, so I'm asking here.
My code is simply generated by GoogleMapsTileCutter plus I've added some code from here for limit panning. This is all code that I have done.

Reset to default 2If it's a matter of simply resizing your map div, then the following JavaScript should lead you in the right direction:
function resizeMap() {
var myMap = document.getElementById('map-canvas');
myMap.style.height = 100%;
myMap.style.width = 100%;
}
Note that the percentages are only relative to ancestor elements of your map div.
Then you'd map your buttons onclick to the resizeMap() function and you're set!
If you wanted a jQuery approach, this is what the above code could look like:
function resizeMap() {
$("#map-canvas").css({height: 100%, width: 100%});
}
To revert the map back to its original width and height, you could first check if the width and height are set to 100%, then resize, but a more elegant solution would be to use a class instead of inline styles, which could resemble the following:
function resizeMap() {
var myMap = document.getElementById('map-canvas');
myMap.classList.toggle("fullscreen");
}
Then in your css you can have:
.fullscreen {
width: 100%;
height: 100%;
}
Clicking the button would just toggle between turning the class on and off.
Like this, the answers above do not work.
var mapOptions = {
center: myCenter,
zoom: 9,
fullscreenControl: true
};
