Google maps adding streetview to each infowindow - google-maps

Question

I would like to add streetview to each infowindow but I can't figure out how to integrate the code. I tried putting the code where the comments are set and that works half. Still have to learn a lot about programming.
html += '<div id="content" style="width:200px;height:200px;"></div>';
var pano = null;
google.maps.event.addListener(infoWindow, 'domready', function () {
if (pano != null) {
pano.unbind("position");
pano.setVisible(false);
}
pano = new google.maps.StreetViewPanorama(document.getElementById("content"), {
navigationControl: true,
navigationControlOptions: { style: google.maps.NavigationControlStyle.ANDROID },
enableCloseButton: false,
addressControl: false,
linksControl: false
});
pano.bindTo("point", marker);
pano.setVisible(true);
});
I'm using this code:
function load() {
var map = new google.maps.Map(document.getElementById("map_canvas"), {
center: new google.maps.LatLng(41.640078, -102.669433),
zoom: 3,
mapTypeId: 'roadmap'
});
var infoWindow = new google.maps.InfoWindow;
downloadUrl("mymap.php", function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var name = markers[i].getAttribute("name");
var address = markers[i].getAttribute("address");
var type = markers[i].getAttribute("type");
var point = new google.maps.LatLng(
parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var html = "<b>" + name + "</b> <br/>" + point;
// comment *** streetview here ****
var marker = new google.maps.Marker({
map: map,
position: point
});
bindInfoWindow(marker, map, infoWindow, html);
}
});}
function bindInfoWindow(marker, map, infoWindow, html) {
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent(html);
infoWindow.open(map, marker);
});
}

Working example using DOM elements (rather than using string content):
// this variable will collect the html which will eventually be placed in the side_bar
var side_bar_html = "";
// arrays to hold copies of the markers used by the side_bar
var gmarkers = [];
// global "map" variable
var map = null;
var sv = new google.maps.StreetViewService();
var clickedMarker = null;
var panorama = null;
// Create the shared infowindow with three DIV placeholders
// One for a text string, oned for the html content from the xml, one for the StreetView panorama.
var content = document.createElement("DIV");
var title = document.createElement("DIV");
content.appendChild(title);
var streetview = document.createElement("DIV");
streetview.style.width = "200px";
streetview.style.height = "200px";
content.appendChild(streetview);
var htmlContent = document.createElement("DIV");
content.appendChild(htmlContent);
var infowindow = new google.maps.InfoWindow({
size: new google.maps.Size(150, 50),
content: content
});
// A function to create the marker and set up the event window function
function createMarker(latlng, name, html) {
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
map: map,
title: name,
zIndex: Math.round(latlng.lat() * -100000) << 5
});
marker.myHtml = html;
google.maps.event.addListener(marker, "click", function() {
clickedMarker = marker;
sv.getPanoramaByLocation(marker.getPosition(), 50, processSVData);
// openInfoWindow(marker);
});
// save the info we need to use later for the side_bar
gmarkers.push(marker);
// add a line to the side_bar html
side_bar_html += '<a href="javascript:myclick(' + (gmarkers.length - 1) + ')">' + name + '<\/a><br>';
}
// This function picks up the click and opens the corresponding info window
function myclick(i) {
google.maps.event.trigger(gmarkers[i], "click");
}
function processSVData(data, status) {
if (status == google.maps.StreetViewStatus.OK) {
var marker = clickedMarker;
openInfoWindow(clickedMarker);
if (!!panorama && !!panorama.setPano) {
panorama.setPano(data.location.pano);
panorama.setPov({
heading: 270,
pitch: 0,
zoom: 1
});
panorama.setVisible(true);
google.maps.event.addListener(marker, 'click', function() {
var markerPanoID = data.location.pano;
// Set the Pano to use the passed panoID
panorama.setPano(markerPanoID);
panorama.setPov({
heading: 270,
pitch: 0,
zoom: 1
});
panorama.setVisible(true);
});
}
} else {
openInfoWindow(clickedMarker);
title.innerHTML = clickedMarker.getTitle() + "<br>Street View data not found for this location";
htmlContent.innerHTML = clickedMarker.myHtml;
panorama.setVisible(false);
// alert("Street View data not found for this location.");
}
}
function initialize() {
// Create the map
// No need to specify zoom and center as we fit the map further down.
map = new google.maps.Map(document.getElementById("map_canvas"), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
streetViewControl: false
});
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
// Read the data from example.xml
// downloadUrl("example.xml", function(doc) {
var xmlDoc = xmlParse(xmlData);
var markers = xmlDoc.documentElement.getElementsByTagName("marker");
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
// obtain the attribues of each marker
var lat = parseFloat(markers[i].getAttribute("lat"));
var lng = parseFloat(markers[i].getAttribute("lng"));
var point = new google.maps.LatLng(lat, lng);
var html = markers[i].getAttribute("html");
var label = markers[i].getAttribute("label");
// create the marker
var marker = createMarker(point, label, html);
bounds.extend(point);
}
// put the assembled side_bar_html contents into the side_bar div
document.getElementById("side_bar").innerHTML = side_bar_html;
// Zoom and center the map to fit the markers
map.fitBounds(bounds);
// });
}
// Handle the DOM ready event to create the StreetView panorama
// as it can only be created once the DIV inside the infowindow is loaded in the DOM.
var pin = new google.maps.MVCObject();
google.maps.event.addListenerOnce(infowindow, "domready", function() {
panorama = new google.maps.StreetViewPanorama(streetview, {
navigationControl: false,

addressControl: false,
linksControl: false,
visible: true
});
panorama.bindTo("position", pin);
});
// Set the infowindow content and display it on marker click.
// Use a 'pin' MVCObject as the order of the domready and marker click events is not garanteed.
function openInfoWindow(marker) {
title.innerHTML = marker.getTitle();
htmlContent.innerHTML = marker.myHtml;
pin.set("position", marker.getPosition());
infowindow.open(map, marker);
