Input location with Yahoo's weather API using simpleWeather.js? - javascript

I'm building a web-page that shows the weather. I would like for it to be able to use geolocation, as well as the option to manually input a location to pull weather information. I've got the geolocation working fine, but am unsure as to how to add an additional input using either a city or zipcode.
Here's my relevant code:
if ("geolocation" in navigator) {
navigator.geolocation.getCurrentPosition(function(position) {
loadWeather(position.coords.latitude + ',' + position.coords.longitude);
});
} else {
loadWeather("", "1062617");
}
function loadWeather(location, woeid) {
$.simpleWeather({
location: location,
woeid: woeid,
unit: 'f',
success: function(weather) {
$(".weather-text").html(weatherText[weather.code]);
$(".weather-icon").html('<i class="icon-' + weather.code + '"></i>');
$(".weather-stats").html('<ul><li><strong>'+weather.city+', ' +weather.region+ '</strong></li>');
$(".weather-stats").append('<li>'+ weather.temp + '°F / '+ weather.alt.temp +'°C</li></ul>');
},
error: function(error) {
$("#weather").html('<p>' + error + '</p>');
}
});
}
I'm pretty new to javascript & jquery, so I understand how to make an input box with HTML but am unsure how to use the user input data to then retrieve the associated weather data.

The getCurrentPosition gives you access to the position interface which then gives you the coordinates. So your if statement results in a latitude and longitude based on the device's Geolocation. In order to get this same information from a user's input (latitude and longitude), you need to convert the input (could be City, State or a full address) to coordinates. I recommend using Google maps API to convert that user input.
Once converted, you can then pass the lat and long to loadWeather(). Here's an example of a user's input (Address) converted:
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var geocoder = new google.maps.Geocoder();
var address = jQuery('#address').val();
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
jQuery('#coordinates').val(latitude+', '+longitude);
loadWeather(latitude + ',' + longitude);
}
});
</script>
<input id="address" type="text" placeholder="Enter City, State"/>
Of course you would use the above within proper context such as checking whether geolocation worked first or whenever a user actually enters their address. You might need a Google Maps API for this bit that should be easy to get.
Give it a shot, if stuck, check out this fiddle: jsfiddle
EDIT:
I grabbed Yahoo's Weather API endpoint and here is working fiddle:
https://jsfiddle.net/mjsgwq55/3/
I highly recommend logging variables so you can tell what time of data they contain. In your fiddle, you tried to access a property that doesn't exist in the object. Logging that would easily show you what to use.

Get User Location with Javascript

I want to get the the users current location address(city, street etc) on click event.
I have tried html5 geolocation and tried to console the data. on button click i am checking geo location is supported by creating alert box, and its executes succesfully, But its not printing any values in the console.
HTML
<div id="navbar"><span> Geolocation API</span></div>
<div id="wrapper">
<button id="location-button">Get User Location</button>
<div id="output"></div>
My script
<script>
$('#location-button').click(function(){
if (navigator.geolocation) {
alert("it is supported");
navigator.geolocation.getCurrentPosition(function(position){
console.log(position);
$.get( "http://maps.googleapis.com/maps/api/geocode/json?latlng="+ position.coords.latitude + "," + position.coords.longitude +"&sensor=false", function(data) {
console.log(data);
})
var img = new Image();
img.src = "https://maps.googleapis.com/maps/api/staticmap?center=" + position.coords.latitude + "," + position.coords.longitude + "&zoom=13&size=800x400&sensor=false";
$('#output').html(img);
});
}
else
{
console.log("geo location is not supported")
}
});
</script>
I want to get the full address of the users location.
You may visit this jsfiddle sample that demonstrates your use case.
Kindly note that it is not recommended to use web service in the client side, as web service requests are recommended to be used for server side requests.
As you can see below, what I used is a Geocoder Service instead of the Web Service Geocoding
geocoder.geocode( { 'location': pos}, function(results, status, infowindow) {
if (status == 'OK') {
console.log(results[0].formatted_address);
infoWindow.setContent('Location found: '+ results[0].formatted_address);
infoWindow.setPosition(pos);
infoWindow.open(map);
} else {
console.log('Geocode was not successful for the following reason: ' + status);
}
});
you simply can't! Geolocation use triangulation or GPS from the mobile and you'll get get longitude and latitude values or even the IP and you'll get nearest distributor device(haven't right word in english).
Obviously for geolocation the user have to authorize it too.
So if you want address the simpliest is to ask by a form. You can use a map related with longit/latitude matching but it'll be a pain and waste to do because you've to use all maps and places on earth related to use it that way.

Does Google MAP API Use Async Request

I wrote a small app to test out Google Map API and I noticed that my functions do not execcute in the expected order. Please take a look at my code below.
<!DOCTYPE html><htm><head><title></title>
<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"> </script>
<script>
//Global Variables
var lat, lng, _Address;
var geocoder = new google.maps.Geocoder();
function getReverseGeocodingData(lat, lng) {
var latlng = new google.maps.LatLng(lat, lng);
// Make the Geocode request
geocoder.geocode({ 'latLng': latlng }, function (searchResults,searchStatus) {
if (searchStatus !== google.maps.GeocoderStatus.OK) {
alert("Your search yields " + searchStatus);
}
// Checking to see if the Geocode Status is OK before proceeding
if (searchStatus == google.maps.GeocoderStatus.OK) {
console.log(searchResults);
_Address = (searchResults[0].formatted_address);
alert("First time Address is displayed" + _Address);
}
});
}
function splitAddress() {
var addressArr = _Address.split(',');
//addressArr will be used later
}
// This function is called when the submit button is clicked
function SearchAddress() {
geocoder.geocode({ 'address': "77 Massachusetts Ave, Cambridge, MA 02139" }, function (searchResults, searchStatus) {
var location = searchResults[0].geometry.location;
lat = location.lat();
lng = location.lng();
getReverseGeocodingData(lat, lng);
alert("Second time Address is displayed" + _Address);
splitAddress();
});}
</script></head><body><div><input type="button" value="Submit" onclick="SearchAddress()"></div></body></html>
When I set a break point on the line alert("First time Address is displayed" + _Address), I can tell that this alert function executes before the line alert("Second time Address is displayed" + _Address).
However, the line alert("Second time Address is displayed" + _Address) appears as though it executes first and the value of _Address is undefined. So my question is if the second alert function executes after the first alert function, is Google Map API making an asynchronous request.
Yes, Google Maps API uses asynchronous requests when you call geocoder.geocode.
This is in the documentation.
Accessing the Geocoding service is asynchronous, since the Google Maps
API needs to make a call to an external server.

Javascript Function - Convert Geolocation Code to Street Address

I am looking for a javascript function or jquery library to convert geolocation code (e.g. 42.2342,32.23452) to street address
For examples.
navigator.geolocation.getCurrentPosition(
function(pos) {
$("#lat_field").val(pos.coords.latitude);
$("#long_field").val(pos.coords.longitude);
}
);
Here is a google api URL to get address data
http://maps.googleapis.com/maps/api/geocode/json?latlng=41.03531125,29.0124264&sensor=false
I want to see "formatted_address" : "Hacı Hesna Hatun Mh., Paşa Limanı Cd 2-26, 34674 Istanbul, Türkiye",
navigator.geolocation.getCurrentPosition(
function(pos) {
$("#lat_field").val(pos.coords.latitude);
$("#long_field").val(pos.coords.longitude);
$("#adress_data").getaddrfromlatlong(pos.coords.latitude,pos.coords.longitude)
}
);
This function should be how ?
``getaddrfromlatlong()
Try this:
<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var geocoder = new google.maps.Geocoder();
var latLng = new google.maps.LatLng(41.03531125,29.0124264);
if (geocoder) {
geocoder.geocode({ 'latLng': latLng}, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
console.log(results[0].formatted_address);
}
else {
console.log("Geocoding failed: " + status);
}
});
}
</script>
I haven't done it in Javascript but I did something similar using the google maps web service to download XML and parse the data out of it. They also have a JSON interface as well which is likely what you'd want to use. It really is rather trivial (download the data, then grep it) so I don't think you'll need a prewritten library for it.

Google Maps Geocoder not giving results

I am using jQuery with the Google Maps API V3's Geocoder. The site user enters a location in the textbox and clicks on the submit button, which calls the code below to geocode the address given by the user into LatLng coordinates.
$(function(){
$("#searchbox_form #search_button").click(function(){
var address = $("#location").val();
var geocoder = new google.maps.Geocoder();
alert(address);
geocoder.geocode( { 'address': address}, function(results, status) {
alert("123");
if (status == google.maps.GeocoderStatus.OK) {
$("#user_lat").val(results[0].geometry.location.lat);
$("#user_lng").val(results[0].geometry.location.lng);
alert("lat: " + $("#user_lat").val());
alert("lng: " + $("#user_lat").val());
} else {
alert("asdasdasd");
alert(status);
}
});
});
});
However there is some problem. You will notice I placed several alert()s in the code. When 'Boston' is entered into the textbox and the submit button is clicked, only alert("address"); is executed showing Boston but alert("123") does not run. Did something go wrong somewhere?
Solution is to disable the submitting of the form :)
Check in any web - debugger whether any request is even made or not?
The code seems fine to me.

Get address coordinates of Google Maps API by ajax() request

I'm trying to get lng and lat coordinates of the Google Maps API by the next example http://jsbin.com/inepo3/7/edit. I expect a 'success' popup, but it keeps showing the 'Error' popup.
The google maps-request gives the correct json feedback (checked by firebug).
<script type="text/javascript">
$().ready(function() {
$.fn.getCoordinates=function(address){
$.ajax(
{
type : "GET",
url: "http://maps.google.com/maps/api/geocode/json",
dataType: "jsonp",
data: {
address: address,
sensor: "true"
},
success: function(data) {
set = data;
alert(set);
},
error : function() {
alert("Error.");
}
});
};
$().getCoordinates("Amsterdam, Netherlands");
});
</script>
Does anyone know how to fix this issue?
Regards,
Guido Lemmens
EDIT
I found a bether solution using the Google Maps Javascript API combined in jQuery:
<script type="text/javascript">
$().ready(function() {
var user1Location = "Amsterdam, Netherlands";
var geocoder = new google.maps.Geocoder();
//convert location into longitude and latitude
geocoder.geocode({
address: user1Location
}, function(locResult) {
console.log(locResult);
var lat1 = locResult[0].geometry.location.lat();
var lng1 = locResult[0].geometry.location.lng();
$("#testDiv").html("latitude:" + lat1 + "<p>longitude:" + lng1 + "</p>");
});
});
</script>
Google Map API V3 makes it harder for external libraries to work with JSONP. Here is a blog post about it.
JSONP and Google Maps API Geocoder Plus A Fix w/ jQuery
An alternative way of getting Geocoding is to use the Google Map V3 API Geocoder Service. Here is an example that i helped a person that was having a similar issue as you to replace his JSONP to use Google Map V3 Geocoder Service. Take a look at this JSFiddle Demo:
This is basically the core. We basically use twitter to get the tweet's address (IE. London, Madrid or Georgia etc) and convert the actual address into LatLng using Google Map's Geocoder Service:
$.getJSON(
url1, function(results) { // get the tweets
var res1 = results.results[0].text;
var user1name = results.results[0].from_user;
var user1Location = results.results[0].location;
// get the first tweet in the response and place it inside the div
$("#last-tweet1").html(res1 + "<p>from: " + user1name + " (" + user1Location + ")</p><p>");
//convert location into longitude and latitude
geocoder.geocode({
address: user1Location
}, function(locResult) {
console.log(locResult);
var lat1 = locResult[0].geometry.location.lat();
var lng1 = locResult[0].geometry.location.lng();
$("#testDiv").html("latitude:" + lat1 + "<p>longitude:" + lng1 + "</p>");
});
});
