Connecting Values to Function after Click Event - javascript

I'm trying to implement text search fields in the Google Places API, I created text fields as well as a click event that leads to the 'calcRoute()' function. I'm having trouble setting the in the text fields to the variable 'start' and 'end' (at least I think that's the porblem). Can anyone help me out? The directions list should appear on the right of the map.

I think you're using getElementById without setting any IDs in your HTML
<!-- Elements don't have IDs -->
<input type="text" data-bind="value:start"/>
<input type="text" data-bind="value:end"/>
Try this:
<input id="start" type="text" data-bind="value:start"/>
<input id="end" type="text" data-bind="value:end"/>
Now when this code gets called, the elements should be found
var start = document.getElementById('start').value;
var end = document.getElementById('end').value;

Getting user's location for google Maps

So I'm trying to have google maps with direction service It works fine until I try to get the user's location to use as a start point. The idea is to give a user directions from their current location to one of the three. I have been following along with some guides on on Google's API.
When I try to get the user's location I try using:
if (navigator.geolocation) {
var position = navigator.geolocation.getCurrentPosition();
googleCoords = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
}
else {
alert("No geolocation!");
}
But for some reason this breaks the map? Trying to get the user's coordinates in a variable to use in the Directions services and as an origin for the map. Thanks

You must do into a function getCurrentPosition.
navigator.geolocation.getCurrentPosition(function(position) {
var pos = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
you should get the position from callback function like this.
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position){
var googleCoords = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
});
} else {
alert("Geolocation is not supported by this browser.");

Getting TravelTime from Google Maps API for Javascript

I am trying to get travel time with traffic between two locations.
I have followed the documentation guide with all details, but I always get a fixed traveltime between two points regardless to trafficmodel: (best_guess, pessimistic or optimistic).
Also, I tried to change the value of departure time to different dates in future but I always get the same result.
Edit:
I am using a standard API key.
Also, I have tried to change date format for [departureTime:] but did not help.
My main goal is to get travel time on links with traffic.
Thanks for helping.

It seems this has nothing to do with your code. Instead, it is a matter of licensing. Your are using Driving Options (BEST_GUESS, OPTIMISTIC,PESSIMISTIC) which is a feature that belongs to Premium Plan clients. The way I see it, you need to buy the license first and use the Premium clientID before you can use this.
"You must supply a Google Maps APIs Premium Plan client ID when
loading the API if you want to include a drivingOptions field in the
DistanceMatrixRequest."
Your client ID
Upon purchasing your Google Maps APIs Premium Plan license, you will receive a welcome email from Google that contains your client ID. Your client ID is used to access the special features of Google Maps APIs Premium Plan. All client IDs begin with a gme- prefix.
This client ID is not a key. It will only work from URLs which you authorize, so you don't need to worry about keeping it secret.
Maybe your date format is not correct ?
Try :
departureTime: new Date("2016-06-14T11:13:00");

Google Maps + Streetview issue - How to disable Photo Sphere

So on my site I'm using Google Maps + Streetview:
https://developers.google.com/maps/documentation/javascript/examples/streetview-simple
Also I'm using standard searchbox with autocomplete, the problem is when I enter some locations, there is no streetview, just Photo Sphere image without any controls for moving around like in standard streetview...
I really don't want Photo Sphere, because I want my users to freely move around with street view, and now they sometimes get "trapped" in one Photo Sphere image... Is there a way I can force streetview without Photo Sphere?
I'm not sure how to turn off PhotoSpheres, but I did find a workaround that may be useful to you. I noticed at https://developers.google.com/maps/documentation/javascript/reference#StreetViewSource that when searching for a location, if you set the source to OUTDOOR, then PhotoSpheres are not returned.
Therefore, if you add listeners for location changes, and then search for the location without PhotoSpheres, I think you should be able to prevent them from showing up.
Here is a modified google maps example to illustrate:

ok, when you are using google FormElement you don't have to call calcRoute() in the input element.
Just use following code, and it will work.
1) Google form submission:
var places = searchBox.getPlaces();
calcRoute(places[0].geometry.location);
2) calcRoute Function's first parameter:
var start = new google.maps.LatLng(places.A,places.F);
3) if you want to use setpanel() method, just place this code below directionsDisplay.setMap(map);
this will work.
directionsDisplay.setPanel(document.getElementById('panel'));

Issues with opening KML/KMZ with google maps api?

I am having issues with overlaying a kml that I have created and have hosted on google drives and locally, with neither working. The documentation with google api help says only a kml that is "publically available" is able to be embeded. How can I get my custom KML/KMZ to be able to embed?
