and here is my website where I work on this project http://147.175.98.165/zadanie7/thirdpage.php
Google maps has a lot of race conditions. I use this code a lot to display them instead. This code should be in a ready event like jquery ready.
new Promise(function (resolve, reject) {
if (!document.getElementById('google-maps')) {
var fileref = document.createElement('script');
fileref.setAttribute("type", "text/javascript");
var link = "https://maps.googleapis.com/maps/api/js?key=AIzaSyDPAizH-vug5nDhwYi0C5Km-pCiQRx7wpY&callback=mapsFinishedLoading";
fileref.setAttribute("async", "async");
fileref.setAttribute("defer", "defer");
fileref.setAttribute("src", link);
fileref.setAttribute("id", 'google-maps');
window.mapsFinishedLoading = resolve;
document.getElementsByTagName("body")[0].appendChild(fileref);
} else {
resolve();
}
}).then(function (result) {
//Your map should be available now
mapOptions={};//put your options here
var map = new google.maps.Map(document.getElementById('map'), mapOptions);
});
Make sure your map div is visible before calling
var map = new google.maps.Map(document.getElementById('map'), mapOptions);

Tiles may not load if your map canvas is invisible when map is initializd.But you can trigger tiles loading by using resize.Since you are using you need to first store a reference to map object.
map = new google.maps.Map(document.getElementById('test'), mapOptions),
tmp = map;
And call resize event on map when your modal gets shown
$('#myModal').on('shown.bs.modal', function () {
google.maps.event.trigger(tmp, 'resize')
})
I am using Intel XDK to try and get the google maps displayed on the screen at the location set in Intel XDK. However, I am having issues with actually displaying the map on the screen, after spending many hours researching trying to figure out why it isn't working I have hit a brick wall and I have no idea how to proceed from here.
So any help will be greatly appreciated to point me in the right direction, thanks in advance.

You need to have permission to use Google API. I used the Google Maps widget and tried with two locations, Statue of Liberty and Taj Mahal. I was able to make it work in emulator as well as on the Intel XDK Preview apps on my phones. Details are in this post:
http://hodentekmobile.blogspot.com/2016/07/intel-xdk-controls-6-using-google-map.html
Here are the settings I used for the widget:
I downloaded this code on google map using jquery mobile from this site. when i run this code direct on the browser, it works but when i called it from another page it display every other content on the page except the google map unless i reload the page. now i need to manually refresh the google map div in the code below when button is clicked using juery eg.
<div id="map_canvas" style="height:300px;" id1="show"></div>
below is the entire code

Have you tried this?
In your

});
Try this.
$("#button_id'").click(function(){ initialize(); });
I'm doing a project in Jquery Mobile and having a problem with the Google API. When I navigate to the MapPage from diffrent page the MapPage by itself shows the map OK, but when moving from the HomePage to MapPage it only shows half of the map. If I manually refresh or resize map it will fix it - but I've tried map.resize() without luck so I need a different solution.
I've attached my HTML code of the HomePage and MapPage below:

My javascript file:

var map;
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var israel = new google.maps.LatLng(32.0938254, 34.7786934); // the var for our initial point
var mapOptions = {
zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: israel // where to center the map on initial!
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
directionsDisplay.setMap(map);
}
function calcRoute() {
initialize();
var start = document.getElementById('startInput').value;
var end = document.getElementById('end').value;
var distanceInput = document.getElementById("distance");
var request = {
origin: start,
destination: end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
distanceInput.value = response.routes[0].legs[0].distance.value / 1000;
}
});}
google.maps.event.addDomListener(window, 'load', initialize);
function getMarker() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition,showError);
}
}
function showPosition(position) {
var lat=position.coords.latitude;
var long=position.coords.longitude;
marker(lat,long); //calls the marker function
}
function showError(error)
{
alert ("Error loading map");
}
function marker(lat,long) {
var myLatlng = new google.maps.LatLng(lat,long);
var mapOptions = {
zoom: 12,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
$("#startInput").attr("value",myLatlng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"You are Here!"
});
}
The map div has zero width. To use a percentage width, you have to define the width of all its parents (or at least up to a fixed size element that can be used to compute the width).
See Mike Williams' Google Maps API v2 tutorial page on percentage sizing
You need to call checkResize() API function. Like This:
map = new google.maps.Map(document.getElementById("map"), mapOptions);
map.checkResize()
This one worked for me as well
I am working with the jQuery mobile google maps example here, focusing on the first "Basic Map Example".
http://jquery-ui-map.googlecode.com/svn/trunk/demos/jquery-google-maps-mobile.html
I want to be able to dynamically add markers to the basic_map, but I am having some trouble. I'm new to jQuery mobile and JavaScript.
Here is my edited version of the basic-map example from the jQuery mobile UI website. If you save it in the jQuery mobile demos folder, then everything should render properly. I have added a button at the bottom of the map page and also the addMarkers function. When you load the page, the map shows up centered at the mobileDemo coordinates (-41, 87), which is close to chicago, but not quite there. When you click on the button, I want to update the map with another marker at the chicago point, but the screen goes blank.
This is just a mock example of what I really want to do. In my longer, more complicated program, I'm querying a database to find addresses that match the query, then I want to put those markers up on the map dynamically. What do I need to change about this source code to be able to plot the Chicago point (or other markers on the fly)?

Please check the below example.
In the first map load there isn't any marker. When you click the button then a marker is dynamically added without a need for page or map refresh.
