google map is not showing - javascript

I'm trying to insert a Google map into a modal. The modal shows up with the shape of the map present but it's all over gray. I've searched and found suggestions such as calling the map's resize event, or setting the max-width of the map image to none, but none of these suggestions have helped so far.please help me.
javascript
var map;
var myCenter=new google.maps.LatLng(53, -1.33);
var marker=new google.maps.Marker({
position:myCenter
});
function initialize() {
var mapProp = {
center:myCenter,
zoom: 14,
draggable: false,
scrollwheel: false,
mapTypeId:google.maps.MapTypeId.ROADMAP
};
map=new google.maps.Map(document.getElementById("map-canvas"),mapProp);
marker.setMap(map);
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map, marker);
});
};
google.maps.event.addDomListener(window, 'load', initialize);
google.maps.event.addDomListener(window, "resize", resizingMap());
$('#myMapModal').on('show.bs.modal', function() {
//Must wait until the render of the modal appear, thats why we use the resizeMap and NOT resizingMap!! ;-)
resizeMap();
})
function resizeMap() {
if(typeof map =="undefined") return;
setTimeout( function(){resizingMap();} , 400);
}
function resizingMap() {
if(typeof map =="undefined") return;
var center = map.getCenter();
google.maps.event.trigger(map, "resize");
map.setCenter(center);
}
html
<div class="modal fade" id="myMapModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">

css
#map-canvas {
margin: 0;
padding: 0;
height: 100%;
}
#map-canvas {
width:500px;
height:480px;
}

Do the model the map div is not visible at startup and the is not created porperly .. i suggest you of recall the initialize function in resizeMap on resizenMap function
function resizeMap() {
initialize()
if(typeof map =="undefined") return;
setTimeout( function(){resizingMap();} , 400);
}
function resizingMap() {
initialize()
if(typeof map =="undefined") return;
var center = map.getCenter();
google.maps.event.trigger(map, "resize");
map.setCenter(center);
}
and anyway you must "initialize" the map when you open the modal .. the div containing the map must be visible when the map is created ..

var num_markers = locations.length;

});
this.setVisible(false);
infowindow.open(map);
});
}
}
init();
</script>
The script displays 2 points on the google map.
I have a problem with centering the map on these points. Currently, I enter the coordinates of the centering of the map in the page code, however points on the map are added from the CMS and must center automatically :(
Does anyone know how to do it?
Do you need to center on one point? scaisEdge answer will do that for you.
map.setCenter(new google.maps.LatLng(lat, lng));
Else if what you need is to center on the 'center' of those two points. You'll need to calculate the center point between those two and then center on this new LatLong. For that you can check Google Maps Javascript API
and this post of stackoverflow: Find center of multiple locations in Google Maps
You could use setCenter()
map.setCenter(new google.maps.LatLng(lat, lng));
eg for center on the first marker
map.setCenter(new google.maps.LatLng(locations[0][1], locations[0][2]));

Google Maps API (JavaScript): Maps not showing

I'm obviously making a thing which is meant to show a Map.
Literally nothing happens - no Map, no Errors, no crash and burn.
Here is my code:
<div style="height:100%; width: 100%;">
<div id="map-canvas"></div>
</div>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyDpgrLi55xM68AaSJOQPX5nzEOV7sw4KVY&callback=initMap"></script>
<script>
function initMap() {
var mapCanvas = document.getElementById("map-canvas");
var mapOptions = {
center: new google.maps.LatLng(53.419824, -3.0509294),
mapTypeId: 'satellite',
scrollwheel: true
}
var map = new google.maps.Map(mapCanvas, mapOptions);
}
</script>
I've tried changing the width/height of the parent div to PX's with no luck.
Any help is great
Cheers

I would say you have two issues.
your map div doesn't have a size (you don't specify the size of the containing element for the anonymous div <div style="height:100%; width: 100%;">).
your MapOptions doesn't contain the required/manditory zoom property.
proof of concept fiddle
code snippet:
function initMap() {
var mapCanvas = document.getElementById("map-canvas");
var mapOptions = {
center: new google.maps.LatLng(53.419824, -3.0509294),
zoom: 5,
mapTypeId: 'satellite',
scrollwheel: true
}
var map = new google.maps.Map(mapCanvas, mapOptions);
}
html,
body,
#map-canvas {
height: 100%;
width: 100%;
margin: 0px;
padding: 0px
}
<div style="height:100%; width: 100%;">
<div id="map-canvas"></div>
</div>
<script deferred async src="https://maps.googleapis.com/maps/api/js?callback=initMap"></script>
I think the problem is in how you've described the new map in your mapOptions variable. Try changing the syntax to something like this, passing mapCanvas as the first argument and the options as the second argument:
var mapOptions = new google.maps.Map(mapCanvas, {
center: {lat: 53.419824, lng: -3.0509294},
mapTypeId: 'satellite',
scrollwheel: true
});
I hope this helps!
<div style="height:100%; width: 100%;">
Maybe problem in height. Try change to 400px.
Or
<div style="height:400px; width: 100%;">
<div id="map-canvas" style="height:100%; width: 100%;></div>
</div>
EDIT
<div style="height:100%; width: 100%;">
<div id="map-canvas"></div>
</div>
<script>
function initMap() {
var mapCanvas = document.getElementById("map-canvas");
var mapOptions = {
center: new google.maps.LatLng(53.419824, -3.0509294),
mapTypeId: google.maps.MapTypeId.SATELLITE,
scrollwheel: true

var map = new google.maps.Map(mapCanvas, mapOptions);

Google Map Street View Not Working - grayed out

www.bchomescondos.ca/properties/?city=Burnaby&id=261618646
www.bchomescondos.ca/properties/?city=Burnaby&id=261711367
These are just the few of the sample pages where the problem is arising. I am not too proficient with the Google Map API, but still tried to incorporate on my website.
I have added three tabs- one showing the road map, another the street view and the third is the walkscore. While the road map and walk-score is working fine, the street view isn't.
But one strange thing I have noticed is if the page is resized (just for any weird reason) the street view map appears.
I would be very much obliged if anyone helps me with this problem.

So, it can be deduced that there is no problem with the map api and it's script. The problem lies with how the CSS tabs are handled.
Thanks duncan for your help. I would open a new question regarding solving this CSS and JS problem.

how to center my google map script with divs?

so far the text is centered the google maps page hugs the left and then the text underneath it remains centered, i just want the map to be centered.
<div id="row1">

<div id="gmap_canvas" style="height:500px; width:600px;"></div>
Below text
</div>
Style:
#row1 {
text-align: center;

Google Map JavaScript:
<script type="text/javascript">
function init_map() {
var myOptions = {
zoom: 16,
center: new google.maps.LatLng(20.0820037, -14.26733380000002),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("gmap_canvas"), myOptions);
marker = new google.maps.Marker({
map: map,
position: new google.maps.LatLng(20.0820037, -14.26733380000002)
});
infowindow = new google.maps.InfoWindow({
content: "<b>Crokson Dine In</b><br/>43 Gill Rd<br/>09521 Hovill"

google.maps.event.addListener(marker, "click", function() {
infowindow.open(map, marker);
});
infowindow.open(map, marker);
}
google.maps.event.addDomListener(window, 'load', init_map);
</script>
text-align: center cannot center a block element itself. You need auto margins:
<div
id="gmap_canvas"
style="height:500px; width:600px; margin-left: auto; margin-right: auto;">

Meteor:Boostrap modal issue with google maps

Well i'm trying to put a google map into a bootstrap modal, but the images on the map looks like doesn't download or fit well,
this is my js code:
Template.map_template.rendered = function (){
Tracker.autorun(function () {
initialize();
});
};
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(51.219987, 4.396237),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
Tracker.autorun(function () {
$('#map-modal').on('shown.bs.modal', function() {
console.log("Se corre esta funcion")
var currentCenter = map.getCenter(); // Get current center before resizing
google.maps.event.trigger(map, "resize");
map.setCenter(currentCenter); // Re-set previous center
});
});
}
And this is my template:
<template name="map_template">
<div id="map_canvas">
</div>
</template>
I tried putting this on my css,
#map_canvas img {
max-width: none;
vertical-align: baseline; }
#map_canvas {
max-width:600px;
height: 200px;}
Actually i tried almost everything, and idk if there is something on the boostrap.css or bootstrap.js (Bootstrap 3)that i need to remove or change but my map looks like this:
Guys I hope you can help me, thanks!
Add a callback after the map is loaded and resize it here.
google.maps.event.addListenerOnce( map, 'idle', function() {
var currentCenter = map.getCenter(); // Get current center before resizing
google.maps.event.trigger(map, "resize");
map.setCenter(currentCenter);
});
It is because of bootstrap's default 15px padding, set it forcefully 0 with using !important and remove scroll bar using overflow:hidden.
Try this
.modal-body{
padding:0 !important;
overflow: hidden !important;
}
Template.map_template.rendered = function (){
Tracker.autorun(function () {
initialize();
});
};
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(51.219987, 4.396237),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
Tracker.autorun(function () {
$('#map-modal').on('shown.bs.modal', function() {
console.log("Se corre esta funcion")
var currentCenter = map.getCenter(); // Get current center before resizing
google.maps.event.trigger(map, "resize");
map.setCenter(currentCenter); // Re-set previous center
});
});
}
.modal-body{
padding:0 !important;
overflow: hidden !important;
