I would like to alter the default display of the direction map to either:
Display a zoomed image of the end-point with the route indicated in blue
Display a zoomed-balloon along with the end-point-marker (http://www.birdwingfx.com/jQuery_gps/demo_gps/gps_demo.html)
I made this basic script which only shows the entire route:
<!DOCTYPE html>

I have something of a hack here: http://jsfiddle.net/mR2LV/6/ click submit then click on the red car icon to open the Infowindow.
This script assumes the path is only point A to point B (simple). It uses two separate maps, one that goes into the Infowindow "bubble" and the overall map. The idea is to keep two copies of the same information, and use one for the "zoom". The route is in the variable path.
minimap = new google.maps.Map(document.getElementById("minimap"), miniOptions);
if(document.getElementById("minimap")) {
document.getElementById("minimap").style.display= "block";
infomap.setContent(document.getElementById("minimap"));
}
var path = response.routes[0].overview_path;
google.maps.event.addListener(endMarker, 'click', function(event) {
infomap.open(map, this);
google.maps.event.trigger(minimap, 'resize');
minimap.setCenter(path[path.length-1]);
});
<div id="map_canvas" style="width:100%; height:100%"></div>
<div id="minimap" style="width: 220px; height:200px; display: none"></div>

I’m having a problem with the implementation of google maps within my phonegap build. I have this problem in the browser on my pc and on the Phone itself. When I have the code in isolation it works and shows a map but when I have it within the rest of the code nothing seem te happen. Please help me with this.

Check Your API Key.
It's Getting ExpiredKeyMapError
https://developers.google.com/maps/documentation/javascript/error-messages#expired-key-map-error
Go to -> https://console.cloud.google.com
Select your Project.
And Create New API Key and Try It.
After Add new API key and check your Style
Check Overflow style.
Your Code Works fine Only API Key Is the Problem.
I would like to decide by button whether I draw a rectangle or a circle. That works so far. But if I first press the Circle button and then the Rectangle button, it does not delete the circle. The other way, it's the same. But I want only one object to be displayed at a time. The object which the user pressed at last should display.

Use visible property to show/hide object from canvas.

var canvas = new fabric.Canvas("c");
var rect = new fabric.Rect({
width: 50,
height: 50,
fill: 'green',
visible: false
});
var circle = new fabric.Circle({
radius: 50,
fill: 'blue',
visible: false
});
canvas.add(rect, circle)
function drawRect() {
circle.visible = false;
rect.visible = true;
canvas.requestRenderAll();
}
function drawArc() {
circle.visible = true;
rect.visible = false;
canvas.requestRenderAll();

You need to create another div for the map container and add the width & height for this.
First of all, you need an API Key, which you don't seem to have.
then basically just follow the google maps api tutorial, like you seem to have sorta been doing.
<style>
#map {
height: 400px;
width: 400px;
}
</style>
<div id="map"></div>
<script>
var map;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: -34.397, lng: 150.644},
zoom: 8
});
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap" async defer></script>
(https://developers.google.com/maps/documentation/javascript/examples/map-simple)
I am trying to use the google maps API to load a map and autocomplete a form. However when I try and initialise I can't do it.
I can do this:
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
</script>
And the map works. Places API doesn't. I tried adding &libraries=... to the end but that didn't work. If I add:
<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=geometry">

However the autocomplete form doesn't work
You are not calling the initAutocomplete function. Simplest fix is to call it at the end of initMap.
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
center: {
lat: -34.397,
lng: 150.644
},
zoom: 8
});
initAutocomplete();
}

map = new google.maps.Map(document.getElementById('map'), {

zoom: 8

initAutocomplete();

I want to load 2 google maps using 1 initialize functions on the same page using division class. But the maps are not getting loaded. Can anyone help?
Here is my code:
<!DOCTYPE html>
<html>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3.exp">
</script>
<script>
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644)
};
var map = new google.maps.Map(document.getElementsByClassName('map-canvas'),
mapOptions);
}
</script>
<body>
<div class="map-canvas" style="height:200px;width:200px;border: 1px solid black;" >
<script>
initialize();
//google.maps.event.addDomListener(window,'load',initialize);
</script>
</div><!-- /.panel-body -->
<div class="map-canvas" style="height:200px;width:200px;border: 1px solid black;" >

Ok there are some mayor problems in you source:
Invalid HTML structure
Your script has to be placed in the head tag above the body tag like:
<head>
<title></title>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3.exp">
</script>
<script>
var map;
var map2;
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644)
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
map2 = new google.maps.Map(document.getElementById('map-canvas2'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
You can't initialize the google map by a container class name. All containers had to be unique. As you can see i am creating 2 individual maps 'mapandmap2` and therefore i need two seperate containers in the body tag like:
<div id="map-canvas"></div>
<div id="map-canvas2"></div>
You don't have to call the initialize function in your body tag because it will be called throught the eventListener on window - load
google.maps.event.addDomListener(window, 'load', initialize);
So lets bring it all together:
FIDDLE
getElementsByClassName returns an array of elements
you need to run the initialize function once the document onload event has fired.
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644)
};
elems = document.getElementsByClassName('map-canvas');
for (var i = 0; i < elems.length; i++) {
var map = new google.maps.Map(elems[i],
mapOptions);
}
}
google.maps.event.addDomListener(window, 'load', initialize);
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3"></script>
<div class="map-canvas" style="height:200px;width:200px;border: 1px solid black;">
</div>
<!-- /.panel-body -->
<div class="map-canvas" style="height:200px;width:200px;border: 1px solid black;">
<script>
initialize();
//google.maps.event.addDomListener(window,'load',initialize);
</script>
</div>
