Trying to add button in googlemap infoWindow

I'm trying to add a button in googlemap infoWindow but I'm beginner in javascript and I have spent weeks on this and still not working... So I hope one of you will be able to help me.
To explain you a litle bit... I get markers from a bdd to display them on a map. Then on marker click, a infoWindow opens with all info marker on it.
This is all working perfectly but then is when I don't get it.
I have added a submit button to each infoWindow markers and I would like an action on submit button click (save to database). But the button is not responding at all...
I removed all the code containing the save function to keep it all clear as there is a alert("click") to test the button...
<script type="text/javascript">
var bounds;

Your first problem is the saveBtn is not part of the DOM until the InfoWindow has been opened as you are adding as a string in the InfoWindow content.
Relate questions:
using addDomListener with googlemaps not working
Turn off google map's infowindow.open(map) asynchronous behaviour
Adding Event Listener on button - Javascript
The second problem is that document.getElementsByClassName(class_name_saveBtn); returns an array. Instead of:
document.getElementsByClassName(class_name_saveBtn);
for a single marker, you need:
document.getElementsByClassName(class_name_saveBtn)[0];
for multiple markers/infowindows (get the last one created):
var removeBtn = document.getElementsByClassName(class_name_removeBtn);
removeBtn = removeBtn[removeBtn.length-1];
var saveBtn = document.getElementsByClassName(class_name_saveBtn);
saveBtn = saveBtn[saveBtn.length-1];

url.content not loading image javascript and asp.net mvc

I have my javascript in my view and I am trying to load an image from my database into an info window for my google maps but the image does not load.
Javascript code in view:
$.get("#Url.Action("GetMarkers","Donator")", function (json, status) {
//Global infoWindow object that will be reused by all markers
var infoWindow = new google.maps.InfoWindow();
var marker, data;
//Loop through the json data
for (var i = 0; i < json.length; i++) {
data = json[i];
var latLng = new google.maps.LatLng(data.Latitude, data.Longitude)
//Creating marker and putting it on the map
marker = new google.maps.Marker({
position: latLng,
map: map,
title: data.NpoName + ' says Click Me!'
});
// Creating a closure to retain the correct data, notice how I pass the current data in the loop into the closure (marker, data)
(function (marker, data) {
// Attaching a click event to the current marker
google.maps.event.addListener(marker, "click", function (e) {
var imageUrl = '<%=Url.Content(' + data.VerificationIcon + ')%>';
infoWindow.setContent('<h3 class="info-window-title">' + data.NpoName + '</h3>' + '<hr />' + '<p>Npo type: ' + data.NpoType + '</p>' + '<p>' + data.VerificationStatus + '<img src="' + imageUrl + '" alt="verification icon" class="verification-icon" />' + '</p>' + 'Click here to donate!');
infoWindow.open(map, marker);
});
})(marker, data);
};
});
Code in controller:
public JsonResult GetMarkers()
{
//Disable lazy loading
db.Configuration.ProxyCreationEnabled = false;
//Map marker section
var DynamicMapMarkers = db.tblNpo.Include(zz => zz.tblVerification).Include(xx => xx.tblNpo_Type);
//Set map marker values
foreach (var item in DynamicMapMarkers)
{
DonatorUserViewModel MapMarkers = new DonatorUserViewModel();
MapMarkers.NpoID = item.npo_id;
MapMarkers.NpoName = item.npo_name;
MapMarkers.NpoType = item.tblNpo_Type.description;
MapMarkers.VerificationStatus = item.tblVerification.description;
MapMarkers.VerificationIcon = item.tblVerification.verification_icon;
MapMarkers.Longitude = Convert.ToDouble(item.longitude);
MapMarkers.Latitude = Convert.ToDouble(item.latitude);
MapMarkerList.Add(MapMarkers);
}
var json = MapMarkerList;
return Json(json, JsonRequestBehavior.AllowGet);
}
Main focus area from the code above:
var imageUrl = '<%=Url.Content(' + data.VerificationIcon + ')%>';
infoWindow.setContent('<h3 class="info-window-title">' + data.NpoName + '</h3>' + '<hr />' + '<p>Npo type: ' + data.NpoType + '</p>' + '<p>' + data.VerificationStatus + '<img src="' + imageUrl + '" alt="verification icon" class="verification-icon" />' + '</p>' + 'Click here to donate!');
The format of the way the image is stored in the database ~/Images/DbImages/verified.png
I am not sure why the image isn't loading, or how to work around it. Any help would be appreciated.

Google Maps V3- Place marker and polyline with interval

I have been trying for hours and also referred to a post in this forum but failed. I have a large number of markers, up to 1000 markers on the map. It slows down my map when I try to move the map's position. So I need to set an interval of markers to be shown on the map. Let's say with interval of 10 when there are more than 300 markers. How can I do that? Below is my code :
var trace_markers= [];
var pins = [];
var pin;
function Trace_Pin(Lat, Long, immat, type, site, vitesse, date){
pin = {
latitude: document.getElementById('Lat'),
longitude: document.getElementById('Long'),
immat: document.getElementById('immat'),
date: document.getElementById('date'),
type: document.getElementById('type'),
site: document.getElementById('site'),
speed: document.getElementById('vitesse')
};
pins.push(pin);
ListPin();}
function ListPin()
{
var image_trace = new google.maps.MarkerImage('http://maps.google.com/mapfiles/kml/pal3/icon61.png',
new google.maps.Size(32, 32),
new google.maps.Point(0,0),
new google.maps.Point(16, 16));
if (pins.length > 200){
for ( var i=0; i< pins.length ;i+10){
var vehlatlng = new google.maps.LatLng(pins[i].latitude, pins[i].longitude) ;
var trace_marker = new google.maps.Marker({
map: map,
position: vehlatlng,
icon: image_trace });
trace_marker.tooltip_html = '<div class="tooltip">' + 'Date : ' + pins[i].date + '<br>' + 'Vitesse : ' + pins[i].vitesse + ' km/h' + '<br>' + '<\/div>';
trace_markers.push(trace_marker);
trace_marker.setMap(map);
Liste_Points.push(trace_marker.getPosition());
TraceBounds.extend(trace_marker.position); }
}

Create an array where you have all your markers (300 of them).
Lets assume that is called
allMarkersArray[]
When you create a marker you do not set the map, but you leave it null so it won't be shown on the map. When you want to show the markers you do some math. Lets say that you want to show only the 1/30 (10 out of 300) of the markers. You create another array
shownMarketsArray[]
where you place the markers you want to show and when you put them there you set the map
marker.setMap(map)
Now the criteria of which markers will be shown, and which markers will remain hidden are up to you. If you want the 1/30 of the markers just have a for loop
for(var i = 0; i < allMarketsArray.length/30; i++)
You should take some precautions though (i.e. the array is too small and you want to show all of them).
UPDATE
if (pins.length > 200){
for ( var i=0; i< pins.length ;i+10){
var vehlatlng = new google.maps.LatLng(pins[i].lat, pins[i].long) ;
var trace_marker = new google.maps.Marker({

position: vehlatlng,
icon: image_trace });
trace_marker.tooltip_html = '<div class="tooltip">' + 'Date : ' + pins[i].date + '<br>' + 'Vitesse : ' + pins[i].vitesse + ' km/h' + '<br>' + '<\/div>';
trace_markers.push(trace_marker);
trace_marker[i].setMap(map);
Liste_Points.push(trace_marker.getPosition());
TraceBounds.extend(trace_marker.position); }

Multiple Markers, Single Info Window, Anchored to the bottom of the map

I am having trouble rendering a google map infowindow anchored with multiple markers.
I am using MVC 3 and javascript to render the map, the map renders fine, as well as relative info windows. But I want the info window to be displayed at the bottom of the map, rather than relative to the marker. The starting point for each map could be different based on the country used for search. My javascript is below (which is working)> i just don't know how to change the infowindow:
function initializeMap() {
var countryID = $("#CountryID :selected").val();
var cityID = $("#cities :selected").val();
var regionID = $("#regions :selected").val();
var locationtypeID = $("#LocationTypeID :selected").val();
var filtertype = $("#filtertype").val();
var latlng;
$.ajax({
type: "GET",
url: "/ajaxcalls/getCentre",
data: "cid=" + countryID,
datatype: "json",
success: function (result) {
var gpscoords = (result).split(",");
latlng = new google.maps.LatLng(gpscoords[0], gpscoords[1]);
},
error: function (req, status, error) {
}
});
var myOptions = {
zoom: 7,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
$.ajax({
type: "GET",
url: "/ajaxcalls/getmarkers",
data: "cid=" + countryID + "&rid=" + regionID + "&xid=" + cityID + "&tid=" + locationtypeID + "&filterType=" + filtertype,
datatype: "json",
success: function (result) {
var infowindow = null;
infowindow = new google.maps.InfoWindow({
content: "holding..."
});
$.each(result, function (i, item) {
var gpscoords = (item.GPSCoOrds.toString()).split(",");
var mpos = new google.maps.LatLng(gpscoords[1], gpscoords[0]);
var markerobject = "";
if (item.LocationTypeID == 2) {
markerobject = "atm.png";
}
else {
markerobject = "bank.png";
}
marker = new google.maps.Marker({
map: map,
position: mpos,
draggable: false,
icon: "/content/mapicons/" + markerobject,
title: item.Designation.toString() + " " + item.Address.toString()
});
google.maps.event.addListener(marker, 'mouseover', function () {
var windowcontent = "<div>Site Name: ";
windowcontent = windowcontent + item.Designation + "</div>";
windowcontent = windowcontent + "<div>Address: " + item.Address + "</div>";
windowcontent = windowcontent + "<div>Contact Number: " + item.contactNumber + "</div>";
windowcontent = windowcontent + "<div>Branch Type: " + item.BranchType + "</div>";
windowcontent = windowcontent + "<div>Network Provider: " + item.NetworkProvider + "</div>";
windowcontent = windowcontent + "<div>Network Capacity: " + item.NetworkCapacity + "</div>";
infowindow.setContent(windowcontent);
infowindow.open(map, this);
});
});
},
error: function (req, stats, error) {
alert(error);
}
});
}
$(document).ready(function () {
$("#mapupdater").click(function () {
initializeMap();
});
});
Any help would be appreciated.

Don't anchor the infowindow to the marker with infowindow.open(map, this);
Just do infowindow.open(map);
However you'll still have to tell the infowindow where to appear. Either use the position attribute when creating it, or setPosition() after it's been created.

how to make a clickable phone number in iphone application by using javascript and html5 applied mysql database?

and I know that 1-801-555-1212 will make this certain number be clickable. I tested it and it works fine.
My question is if I do have a variable phone which will call from database via mysql, how can I make this variable be clickable? I've tried a lot of way but none of them work.

but I always just got code error.
anyone can help me??

You can surround the phone number by a "a" tag with a href="tel:{PHONE NUMBER}"
