Google maps fit location to screen with different bounds - javascript

Firstly, I have been checking all over the web but I couldnt find an answer.
I combined autocomplete with goole maps and if a user wants, he/she can move the marker as well and I get address from it. You can find the code below.
When a user searches for instance Nice, France, is it possible to fit Nice from e.g borders to my map? Maybe I have to change the zoom dynamically or I need to set new viewport, I am not sure. So far what I found is, I can give a distance and create a circle to fit that circle to the viewport. But circle's radius is set, so it can fit to Nice but can not fit to Miami.
Hope I could explain what I mean. Thank you in advance.

The Autocomplete service returns the geometry of the location selected, zoom the map to show those bounds (in the fiddle/snippet I added a rectangle to show the bounds returned, if you don't want that displayed, remove it):
var place = autocomplete.getPlace();
if (place.geometry.viewport) {
map.fitBounds(place.geometry.viewport);
} else if (place.geometry.bounds) {
map.fitBounds(place.geometry.bounds);

Google Maps Marker not shown - autocomplete

I have this project with Google Maps API. Everything works perfectly except that Google Marker added through an input value is not showing. I have inputs, of which two are origin and destination respectively, with direction both show perfectly but the third input which is added later doesn't show. I have a different function to take care of it though.
<input type="text" class="form-control" id="origin_input" name="origin_input">
<input type="text" class="form-control" id="destination_input" name="destination_input">
<input type="text" class="form-control" id="stopOver">

You have three issues with your addStopover function:
you are using the wrong map variable
the icon doesn't exists
you are creating the marker before the place_changed event fires and it's callback function runs
working version of the function:
function addStopOverMarker(map) {
var stopOver = new google.maps.places.Autocomplete(document.getElementById('stopOver'));
google.maps.event.addListener(stopOver, 'place_changed', function() {
var coord = stopOver.getPlace().geometry.location;
console.log(coord);
var marker = new google.maps.Marker({
position: coord,
map: map,
draggable: true,
visible: true
});
});

Hope i explained my problem enough.
In your reverseGeocodeResult() function, you take the first result and return its "formatted address" property.
Instead of returning this, try browsing its "address_components" property.

undefined not found ie7

IE7 is giving me an issue with a script, using Google Maps API.
When the page is loaded, it says in a alert box 'undefined not found'.
This only happens in IE7, not IE8, nor IE9. Fine in other browsers too, i guess there is a coding error. As soon as i take out JS, no warning but map doesn't work, obviously.
Here is my entire JS. Thanks in advance!

Google maps api v3 standard marker on my location

I want to set a marker when I open up my google maps page on my current location.
This marker needs to be changed when I enter an adress in the textfield.
I have no clue how I have to add the standard marker on my location and update it when an adress is entered in the textfield.
I already have the Lat & long of the current position.
