Google Maps API v3 Street View "google is not defined" - javascript

I am just getting started with the Maps API and I was trying to copy the following example.
https://code.google.com/apis/maps/documentation/javascript/examples/streetview-simple.html
When I copy the source I get the following error in the script.
google is not defined
Line 11
var fenway = new google.maps.LatLng(42.345573,-71.098326);
This is the html file I am using.

</body>
</html>
The google example loads perfectly but my code does not.
I have seen a few people getting this error but none of the fixes listed seem to work for me. Have I just made a basic error while copying the script?

There is the protocol missing in the path.
//maps.googleapis.com/maps/api/js?sensor=false
should be
http://maps.googleapis.com/maps/api/js?sensor=false
(it's missing in many of the examples)

zoom_changed listener doesn't work for me

I'm trying to use a zoom listener event in a google maps so that I can resize some axis I have in it. As a beginning, I'm trying to use an alert so that I can see whether if the listener detects a change in the zoom level or not, but I'm not able to get any alert at all. My code is the following:

Does anyone see the problem?
The map variable isn't defined when you create the zoom_changed listener, it is created later, when the initialize function runs (also the variable is map, not maps).
code snippet:
var map;
function initialize() {
var centerlatlng = new google.maps.LatLng(49.801674, 11.188139);
var myOptions = {
zoom: 18,
center: centerlatlng,
scaleControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addDomListener(map, 'zoom_changed', function() {
alert("changed");
});
}
google.maps.event.addDomListener(window, 'load', initialize);

You need to set zoom_changed event on the instance of google.maps.Map inside your initialize() function.
map.addListener('zoom_changed', function() {
alert("changed");
});

Trouble with Google Maps Javascript API

I am new to JavaScript and this website, so please bear with me (and my English) I am doing a draft for my HSC project, for this project I am using Google Maps JavaScript API to show the location of an area. I am unable to find the code to disable the sensor, as the old API thing had in it, instead of 'callback', which would disable the user of the website the ability to move the map around. Would anyone here be able to help me with my issue?
The code I am using is the Google's sample code.
(I have not changed the default location to keep some privacy)

Add this to your map:
draggable: false
For example:
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: -34.397, lng: 150.644},
zoom: 8,
draggable: false
});

Third party latitude and longitude are not matching in google map

I have an external json which I am trying to overlay on a google map. The overall plumbing works fine.
The map gets generated. Data gets iterated, and markers are placed by reading the coordinates. But the when i look at the map the coordinates are way off on the map. The data set can not be wrong, i can give my word on that. Is there some adjustment I need to make to get this thing map to each other. Here is my code

Fusion Tables API and google Maps Advanced Visualization [duplicate]

The file "/maps/documentation/javascript/examples/default.css" doesn't exist on your site. Your map doesn't have a valid size.

Google MAP API V3 - Street View

I am trying to integrate the Google maps V3 API into our website. I need to read the address and set it to the MAP API so that map will show the street view for that address.
So I need help in 3 points.
How to read the address values.
Example: var streetAddressArray = getElementsByAttribute(parent.document.forms[0], "*", "smokeid", "Address Line 1"); (I am not sure what this function will do, just pasting to give an idea on what exactly I am looking for.)
After reading the value set to the API classes/methods so that map can show the street view.
Show it as a street view.
This is similar to what I am looking for:

I am very thankful for your response Suvi!
Here is my Program:

</html>
I am facing two issues with this,
Somehow I am not able to view Panorama view. Any issue with my code?
Address for map should come from bunch input fields( address line 1 and City and Zip etc). How can I assign the input fields address to the map so that map will show directly that particular location?
I am using a custom product. I have another example in that they are using:
var streetAddressArray = getElementsByAttribute(parent.document.forms[0], "*", "smokeid", "LossLocation_Address1");
I guess I am little closer to the target, But my this example is not working, it not rendering anything.

Can you help me what went wrong?
You'll need to first initialize StreetView (either in place of or bound to your map), see the StreetView documentation for setting it up (https://developers.google.com/maps/documentation/javascript/streetview). You well then need to use the Geocode service from google to find addresses. This document (https://developers.google.com/maps/documentation/javascript/geocoding) will help you set up a simple Search for addresses, but you'll have to tweak it a little so that it renders the search on your streetview map. Essentially you'll have to change:
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
}
Instead of map.setCenter, you'll need to set the location to panorama.setPosition(results[0].geometry.location);
Keep in mind that the point of view of streetview might not always be positioned to point at the building you want, I don't think Google has a way of telling exactly which side of the street the building/location you're searching for will be.
Hope that helps.
Answers to your 2 issues:
Somehow I am not able to view Panorama view. Any issue with my code?
This is happening because the closing </div> to your map_canvas is enclosing the pano as well. It should come directly after the div for the map_canvas, like so:
<body onload="initialize()">
<div id="map_canvas" style="width:100%; height:100%"></div>
<div id="pano" style="position:absolute; left:410px; top: 8px; width: 400px; height: 300px;"></div>
</body>
Also, make sure you include your API key in the header where you include the google maps api script tag.
Regarding your second question, you can do this in variety of ways. The easiest would be to use input text fields and use jquery's .val() function to get the values in the text fields. Then pass the values to the geocoder to perform your searches.
