How can I mark multiple locations in google map. Latitude and Longitute are getting from my table as json response. Please check below code and json response and correct me?
When I alert(myCenter) latitude and longitude are showing correctly but not showing correctly on map
Json encode
[{"id":"1","lat":"9.9710364","lng":"76.2382596","address":"Ernakulam, pra"},{"id":"2","lat":"9.5946677"
,"lng":"76.5030831","address":"Kochi pra"},{"id":"3","lat":"8.8862925","lng":"76.5850831","address":"Kollam
pra"},{"id":"4","lat":"8.4998965","lng":"76.8543216","address":"Trivandrum pra"}]

There is no need to initialize map instance per every marker, you could change the flow to:
initialize a map
once the data is loaded, place markers on the map
Example
$(function () {
$.ajax({
url: 'https://rawgit.com/vgrem/e2dda2a255a24df92bff/raw/d9c694b635612ee405c7d16c355dca19adb6380c/geo-locations.json',
success: function (data) {
initialize(data);
}
});
});
function addMarker(map,position){
var marker = new google.maps.Marker({
position: position,
title: 'Click to zoom'
});
marker.setMap(map);
// Zoom to 9 when clicking on marker
google.maps.event.addListener(marker, 'click', function () {
map.setZoom(9);
map.setCenter(marker.getPosition());
});
}
function initialize(data) {
var mapProp = {
zoom: 5,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
var bounds = new google.maps.LatLngBounds();
$.each(data,function(pos) {
var pos = new google.maps.LatLng(this.lat, this.lng);
bounds.extend(pos);
addMarker(map,pos);
});
map.fitBounds(bounds);
}

Would someone be able to explain what I need to do to add an array of markers using javascript. I understand that basics of displaying the map and adding a marker or even multiple markers but they have to be hard coded in. I want to display a list of markers from an API.

This part is the javascript and html part of the code
I dont undestand why the google map unable to get user current location in android device but it work on ios simulator i will be very grateful if anyone of you can help me to solve
Its a bad idea to use navigator directly in ionic, i would recommend using ngCordova and its powerful plugins for cross platform features:
http://ngcordova.com/docs/plugins/geolocation/
Apart from this I would also check if you have enabled geolocation for your app.
You should see something like this:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
in your AndroidManifest.xml file
I am setting up a simple map program for a user to see locations on an embedded Google map. I have the map working, but I was wondering if there is a way for the user to input coordinates in AI2 then have the map center there.
Here is the HTML file I am using to display the map.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">

#map_canvas { height: 100% }
</style>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?&sensor=true&language=en"></script>
<script type="text/javascript">
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
// Add a listener for the click event
google.maps.event.addListener(map, 'click', showPosition);
}
function showPosition(event) {
// display a marker on the map
marker = new google.maps.Marker({
position: event.latLng,
map: map,
icon: "./marker.png"
});
// print the selected position to the page title
var position = event.latLng.lat().toFixed(6) + ", " + event.latLng.lng().toFixed(6);
window.document.title = position;
}
</script>
</head>
<body onload="initialize()">
<div id="map_canvas" style="width:100%; height:100%"></div>
</body>
</html>
Yes, that's possible.
You can use WebViewString to communicate values back and forth between your App and the WebViewer. In your App, you get and set the WebViewer.WebViewString properties. In your webviewer, you open to a page that has Javascript that references the window.AppInventor object, using its getWebViewString() and setWebViewString(text) methods.
See also the following snippet for a complete example.
<!doctype html>

<body>
<script>
document.write("The value from the app is<br />" + window.AppInventor.getWebViewString());
window.AppInventor.setWebViewString("hello from Javascript")
</script>

I'm building an app within Phonegap and I've got two parts working on their own, but will not work together.
Here is the HTML I'm trying to render:
<body>
<div id="map"></div>
<div data-role="collapsible-set" id="storeList">
<div data-role="collapsible" data-mini="true">
<h3>Section 1</h3>
<p>I'm the collapsible set content for section 1.</p>
</div>
<div data-role="collapsible" data-mini="true">
<h3>Section 2</h3>
<p>I'm the collapsible set content for section 2.</p>
</div>
</div>
</body>
When my header is in this order, the map shows up, but the jQuery mobile collapsing dropdown does not. This is probably stemming from trying to load jQuery Mobile before jQuery itself.

However, when I flip it around and place jQuery before jQuery mobile, then the collapsible data sets work, but google Maps does not show up. It's just a blank white space.

The CSS that matters:
html, body {

height: 100%;
padding-top: 10%;
}
#map {
width: 100%;
height: 60%;

#storeList {

width: 100%;
position: absolute;
bottom: 0;

z-index: 2
}
The lengthy JavaScript
var app = {
// Application Constructor
initialize: function() {
this.bindEvents();
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
//
// The scope of 'this' is the event. In order to call the 'receivedEvent'
// function, we must explicitly call 'app.receivedEvent(...);'

navigator.geolocation.getCurrentPosition(app.onSuccess, app.onError);
},
onSuccess: function(position){
var longitude = position.coords.longitude;
var latitude = position.coords.latitude;
var latLong = new google.maps.LatLng(latitude, longitude);
var mapOptions = {
center: latLong,
zoom: 13,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
var myLocationMarkerImage = {
url: 'img/blue_dot.png',
anchor: new google.maps.Point(16, 0)
};
var myLocationMarker = new google.maps.Marker({
position: latLong,
map: map,
title: 'my location',
icon: myLocationMarkerImage
});
},
onError: function(error){
alert("the code is " + error.code + ". \n" + "message: " + error.message);
},
};
app.initialize();
TIA!
I was able to figure this out by looking at these two articles:
