Allow user to enter his location (address) in website

I am working on a website that have multiple companies and employees, each company should register by entering its username,password and location on Google maps.
The location is going to appear to employees who are using an android application (Which is connected to the same website's database).
I want to know how to allow the company to specify their exact address either by typing the decimal points of the location or by using the pin to specify it on Google map or by allowing me to detect their location.
I read this: https://developers.google.com/maps/documentation/javascript/tutorial
but I do not know if it is what I need in my case.
Note that it is the first time for me to deal with maps so I am not deep into it.

I hope i understand you correctly.
One option could be something like this:
Get the user device' geolocation and put that position on a map with a draggable marker.
If the position is not correct, marker can be dragged and you will get the new coords - if the marker location has been changed.
Here is the code (with jquery):
var map;
var marker;
function initialize() {
var mapOptions = {
zoom: 11
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
// Try HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var marker = new google.maps.Marker({
position: pos,
map: map,
title: 'Here you are',
draggable: true
});
$('#user-info').append('Location found using HTML5<br/>');
map.setCenter(pos);
google.maps.event.addListener(marker, 'dragend', function(a) {
$('#user-info').append(a.latLng.lat().toFixed(4) + ', ' + a.latLng.lng().toFixed(4) +'<br/>' );
});
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
$('#user-info').append('Error: The Geolocation service failed.');
} else {
$('#user-info').append('Error: Your browser doesn\'t support geolocation.');
}
var options = {
map: map,
position: new google.maps.LatLng(60, 105),
};
map.setCenter(options.position);
}
google.maps.event.addDomListener(window, 'load', initialize);

I hope this will help you.
In case you will need to get the exact address, you have to add geocoding functionality.

how to keep the position of the map to the KML layer rather than current position of the user?

The below java script basically imports a KML layer file on the map and also displays the current location of the user using geolocation in html 5.
The problem is that it zooms to the current location of the user. I do not want that to happen i still want the focus to be on the KML layer routes rather than the current location of the user.
var map;
function initialize() {
var abby = new google.maps.LatLng(49.051078,-122.314221);
var mapOptions = {
zoom: 11,
center: abby
}
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var ctaLayer = new google.maps.KmlLayer({
url:urllink,
preserveViewport: true
});
ctaLayer.setMap(map);
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: pos,
content: 'Location found using HTML5.'
});
// map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: The Geolocation service failed.';
} else {
var content = 'Error: Your browser doesn\'t support geolocation.';
}
var options = {
map: map,
position: new google.maps.LatLng(60, 105),
content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
google.maps.event.addDomListener(window, 'load', initialize);

Comment out the line:
map.setCenter(pos);
which set center to the position of user.
Update: And you will have to add infowindow option:
disableAutoPan: true
to disable auto-pan on open. By default, the info window will pan the map so that it is fully visible when it opens.

Remove the {preserveViewport: true} to the KmlLayer.
var ctaLayer = new google.maps.KmlLayer({
url:urllink
});

How do I add geolocation to this code?

I am currently trying to add geolocation functionality to the following code:
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var marker;
var infowindow;
function initialize() {
var latlng = new google.maps.LatLng(51.507059, -0.122631);
var options = {
zoom: 14,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map-canvas"), options);
var html = "<table/>" +
"<tr><td>Name:</td><td><input id='name' type='text'/></td></tr>" +
"<tr><td><br/>Description:</td><td><input id='description' type='text'/></td></tr>" +
"<tr><td/><td><br/><center><input onclick='saveData()' type='button' value='Save & Close'/></center></td></tr>";
infowindow = new google.maps.InfoWindow({
content: html
});
google.maps.event.addListener(map, "click", function(event) {
marker = new google.maps.Marker({
position: event.latLng,
map: map
});
google.maps.event.addListener(marker, "click", function() {
infowindow.open(map, marker);
});
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
Geolocation Code:
// HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: pos,
content: 'Location found using HTML5.'
});
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: Locations services failed.';
} else {
var content = 'Error: Your browser doesn\'t support geolocation.';
}
var options = {
map: map,
position: new google.maps.LatLng(51.507059, -0.122631),
content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
However, when I attempt to merge the initialize functions, I get the error 'Cannot read property '_e3' of undefined.' If I keep the functions separate, the program simply ignores the geolocation code. So, I'm stuck, and was hoping someone could give me a hand. Thanks a million!
Note: I have tried everything relevant at https://developers.google.com/maps/, and have checked through all of the very similar questions on this site - this is not a duplicate post. Also, please ignore my use of HTML character codes inside the JavaScript - it's the only way to get HTML (infowindow) inside JavaScript (code) inside HTML (webdata) working.

how to open popup on click of a marker from the directions service?

UPDATE
when i click green marker,it's display address of location.can i change it?
LATER EDIT :
is it possible to open popup on click of a marker from the directions service?
or try the other way like only hide a marker from the directions service(green marker) and display only red marker(hide only green marker not it's route)?is it good way?
if not possible, please suggest some alternative ideas.
OLDER:
i have a two types of marker on google map.the red marker is normal marker which represent location.and green marker is route marker(its represent many of waypoints of the map).
I modify the infowindow with textbox.which is open on click red marker.
actually i am trying to do is, first i place multiple markers on google map then i draw route between this markers.this thing is done.reminder thing is on click green marker one popup is opened in which user enter price and then click the button.then i got this value and store it to database.
the problem is:
(1) how to open same infowindow on click of green marker?
in short,how to write a code for display infowindow on click of of green marker.
how to find click event of green marker?
code is:
<script type="text/javascript">
var markerarray=new Array();
//for way points
var waypts=[];
//array in json format for placing multiple marker
var locations = <?php echo json_encode($lat1);?>;
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 11,
center: new google.maps.LatLng(23.0171240, 72.5330533),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
<!-- ************* for placing markers ************ -->
var marker, i;
for (i = 0; i < locations.length; i++)
{
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][3], locations[i][4]),
map: map //enable if you want marker
});
//push value into way points
waypts.push({
location:locations[i][0],
stopover:true
});
//create array for polyline
markerarray[i] = marker.getPosition();//(Array(locations[i][5], locations[i][6]));
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
var data='<div style="height:150px !important"><table><tr><td>Enter Price</td></tr><tr><td><input type="text" name="prc" id="prc" /></td></tr></table></div>';
infowindow.setContent(data);
infowindow.open(map, marker);
}
})(marker, i));
}
<!-- ************** for route between markers ******************* -->
var first=locations[locations.length-1][0];
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
//directionsDisplay = new google.maps.DirectionsRenderer();
directionsDisplay = new google.maps.DirectionsRenderer({
polylineOptions: {
strokeColor: 'red',//"black",
strokeOpacity: 1.0,
strokeWeight: 3
}
});
var start = locations[0][0];//"Bopal, Ahmedabad, Gujarat, India";
var end = locations[locations.length-1][0];//"Nikol, Ahmedabad, Gujarat, India";
//remove start destination from array
waypts.shift();
//remove end destination from array
waypts.pop();
var request = {
origin:start,
destination:end,
waypoints:waypts,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
directionsDisplay.setMap(map);
</script>
Thanks in advance.

It is not impossible but it will take some time for code, The way is if you are using for mobile device then you need to accelerator from your device and call geolocation function on position change I think you understand and the second method is from purely javascript method for that you need to call your geolocation function within set Interval understand also draw line separately from marker your marker function only calls within set Intervals for getting your current location with infowindow. Example is :
var map;
function initialize() {
var mapOptions = {
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
//keep this in setInterval
// Try HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: pos,
content: 'Location found using HTML5.'
});
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: The Geolocation service failed.';
} else {
var content = 'Error: Your browser doesn\'t support geolocation.';
}
var options = {
map: map,
position: new google.maps.LatLng(60, 105),
content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
//close here your set interval
google.maps.event.addDomListener(window, 'load', initialize);

It's possible. You can hide the default marker such that you can build a custom marker on the clicked location. This code is to hide the marker.
var rendererOptions = {
suppressMarkers : true
}
var directionsDisplay = new google.maps.DirectionsRenderer(rendererOptions);

Uncaught TypeError: Cannot read property 'latitude' of undefined

Hi all I have the following code:
var map;
var infowindow;
function getLocation()
{
if (navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(initialize);
}
else{x.innerHTML="Geolocation is not supported by this browser.";}
}
function initialize(position) {
var pyrmont = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: pyrmont,
zoom: 15
});
var request = {
location: pyrmont,
radius: 500,
types: ['restaurant']
};
...
Basically I can get the map to work great if I set the Long/Lat co-ordinates but instead I want these to be passed by getting the users location. With the code above the map is displaying on my phone but with the following error:
TypeError: 'undefined' is not an object (evaluating 'position.coords.latitude')
but on the desktop I get no map and the following error:
Uncaught TypeError: Cannot read property 'latitude' of undefined
Any help would be great I'm a newbie to Javascript and these APis

Later in your code, on your page at http://markhaynes.me/mwp/addloc.html, you're calling google.maps.event.addDomListener(window, 'load', initialize);
This causes Google to call the initialize() function, but it passes an event object as the position parameter instead of the position object you expected.

Well it's not an issue with the geolocation API. Here's a JSFIDDLE of geolocation: http://jsfiddle.net/w4nvZ/3/
There's also the documentation and examples for the API here: http://www.w3schools.com/html/html5_geolocation.asp
Google even has an example of geolocation working with the JavaScript Google Maps API: https://google-developers.appspot.com/maps/documentation/javascript/examples/map-geolocation
var map;
function initialize() {
var mapOptions = {
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map_canvas'),
mapOptions);
// Try HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: pos,
content: 'Location found using HTML5.'
});
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: The Geolocation service failed.';
} else {
var content = 'Error: Your browser doesn\'t support geolocation.';
}
var options = {
map: map,
position: new google.maps.LatLng(60, 105),
content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
google.maps.event.addDomListener(window, 'load', initialize);
