Good day,
Does anyone have an idea of how to change a bing map to google map api code. I have found a very useful code on line that is coded using bing maps and would like to change it to work with google maps. if found the code here: http://blogs.msdn.com/b/crm/archive/2011/01/19/custom-charting-capabilities-in-microsoft-dynamics-crm-2011.aspx
Code below:

There is no easy out of the box solution for what you are looking for.
Google API has many differences. For example, the Google API leaves keeping track of map children to the programmer (you). There is no means of looping through the map controls like there is with the Bing API. This means that your solution for saving the map content and re-displaying it will be a little different.
Although, since both API's are done via javascript, all you need to do is convert your functionality according to their documentation;

I'm new to Google Data Studio and looking into building a community connector for our Saas service.
For the configuration section, I need to use the Stepped Configuration process. Basically, I nested set of drop-down lists.
However, I need the data to populate those lists to come from my API. I have the REST service endpoints defined, but I cannot find any documenation/examples of how I'd configure this in the getConfig section of the community connector.
Does anyone have a working example I could use as reference?
In reviewing the documentation, there is a section on stepped configurations, which is what I am looking for. You can find that example here: https://developers.google.com/datastudio/connector/stepped-configuration#dynamic_dropdowns
In this example, they show the following for defining the dropdown values.
Notice for the states, they have hard-coded the values for "Illinois" and "California".
My question is, how can I dynamically call API to retrieve values to populate this list? I have 3 nested dropdowns, each with a separate API call, using the answer from previous dropdown to drive the next.
For example first API might be http://myapi.com/countries which returns list of countries.
When they select country, next API call might be http://myapi.com/states?country=US
etc.
config.newSelectSingle()
.setId("state")
.setName("State")
// Set isDynamic to true so any changes to State will clear the city
// selections.
.setIsDynamic(true)
.addOption(config.newOptionBuilder().setLabel("Illinois").setValue("IL"))
.addOption(config.newOptionBuilder().setLabel("California").setValue("CA"));
if (!isFirstRequest) {
var city = config.newSelectSingle()
.setId("city")
.setName("City");
var cityOptions = optionsForState(configParams.state);
cityOptions.forEach(function(labelAndValue) {
var cityLabel = labelAndValue[0];
var cityValue = labelAndValue[1];
city.addOption(config.newOptionBuilder().setLabel(cityLabel).setValue(cityValue));
});
}
return config.build();
}
Worked through the issues I was having. For others who might have hit similiar issues, here's my working getConfig() method.
function getConfig(request) {
var config = cc.getConfig();
var configParams = request.configParams;
var isFirstRequest = configParams === undefined;
if (configParams ===undefined || configParams.tab ===undefined) {
config.setIsSteppedConfig(true);
}
var url ='https://<yourAPIURL>';
var userProperties = PropertiesService.getUserProperties();
var key = userProperties.getProperty('dscc.key');
var mykey ="Bearer " + key
var options = {
"method" : "GET",
"headers" : {
"AUTHORIZATION" : mykey,
"cache-control": "no-cache"
}
};
var response = UrlFetchApp.fetch(url,options);
var parsedResponse = JSON.parse(response);
var zoneControl = config.newSelectSingle()
.setId("zone")
.setName("Zone")
.setIsDynamic(true);
parsedResponse.map(function(itm) {
zoneControl.addOption(config.newOptionBuilder().setLabel(itm.name).setValue(itm.id))
});
if(configParams !==undefined && configParams.zone !==undefined){
var blockurl ='https://<yourAPIURL>?zoneid='+ configParams.zone;
var blockResponse = UrlFetchApp.fetch(blockurl,options);
var parsedBlockResponse = JSON.parse(blockResponse);
var blockControl = config.newSelectSingle()
.setId("block")
.setName("Block")
.setIsDynamic(true);
parsedBlockResponse.map(function(itm) {
blockControl.addOption(config.newOptionBuilder().setLabel(itm.name).setValue(itm.blockKey))
});
}
if(configParams !==undefined && configParams.block !==undefined){
var taburl =''https://<yourAPIURL>?blockKey='+ configParams.block;
var tabResponse = UrlFetchApp.fetch(taburl,options);
var parsedTabResponse = JSON.parse(tabResponse);
var tabControl = config.newSelectSingle()
.setId("tab")
.setName("Tab")
parsedTabResponse.map(function(itm) {
tabControl.addOption(config.newOptionBuilder().setLabel(itm.name).setValue(itm.internalname))
});
}
return config.build();
}
without testing the code:
function getConfig(request) {
var configParams = request.configParams;
var isFirstRequest = configParams === undefined;
var lst=["A","B","C"]; // your values obtained from REST
var tmp=config.newSelectSingle(); //add element to side
var element=tmp.setId("state").setName("State").setIsDynamic(true); // set name and id
for(var i in lst) // set all the values:
{
element = element.addOption(config.newOptionBuilder().setLabel(lst[i]).setValue(lst[i]))
}
if(isFirstRequest || configParams.state==undefined) // no state selected yet
{
config.setIsSteppedConfig(true); // stop here
}
else
{
// next dropdown element,
// Rest API with element set to: configParams.state
var lst2= ["x","y","z"]
var tmp2=config.newSelectSingle(); //add element to side
var element2=tmp2.setId("element2").setName("Element 2 depends on "+configParams.state).setIsDynamic(true); // set name and id
for(var i in lst2) // set all the values:
{
element2 = element2.addOption(config.newOptionBuilder().setLabel(lst2[i]).setValue(lst2[i]))
}
// code for 3rd
}
}
If the user changes the first dropdown value alle other drop downs have to be reset. This may be a bit tricky.
I inserted a map on my webpage by using the Leaflet library. What I want to do is to show a map zoomed on a specific region according to which city the user types into a text field.
I firstly initialized my map on my JS file:
function initMaps(){
map = L.map('leaflet').setView([0, 0], 13);
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
maxZoom: 18,
'attribution': 'Map data © OpenStreetMap contributors'
}).addTo(map);
}
My javascript code also has an Ajax call.
What I want to do now is to reset the coordinates on the Ajax call.
I wrote the following:
var readCoordinates = function(){
$.ajax({
url: "https://nominatim.openstreetmap.org/search?q=" + encodeURIComponent($("#inlineFormInputCitta").val()) + "+Italy&format=geocodejson",
dataType: "json",
success: function (data) {
setTimeout(function () {
for (let i = 0; i < data.features.length; i++) {
let coordinate = data.features[i].geometry.coordinates;
console.log(coordinate);
map.setView(coordinate, 13);
console.log("ajax and for loop have been activated");
console.log(coordinate.geometry.coordinates);
};
$("#ristoranti").prop("disabled", false);
}, 1000);
}
});
};
The API I'm referring to in the URL is the following: https://nominatim.openstreetmap.org/search?q=Roma%20Italy&format=geocodejson
What I did is trying to reset the coordinates here: map.setView(coordinate, 13);
after having cycled the elements in the JSON object, see the following:
for (let i = 0; i < data.features.length; i++) {
let coordinate = data.features[i].geometry.coordinates;
I may display several coordinates in the console, see the following:
That's because in the JSON file I get through the API request there are several:
The result of this is the following map, which isn't zoomed anywhere:
Which coordinates should I take in order to display that specific region?
EDIT - - -
I changed the code because I'm trying to get a specific subobject, i.e. the one in the screen below (which has "type" = "city"):
The new snippet is the one below, where I add an if statement:
var readCoordinates = function(){
$.ajax({
url: "https://nominatim.openstreetmap.org/search?q=" + encodeURIComponent($("#inlineFormInputCitta").val()) + "+Italy&format=geocodejson",
dataType: "json",
success: function (data) {
setTimeout(function() {
for (let i = 0; i < data.features.length; i++) {
debugger;
let type = data.features[i].properties.geocoding.type;
if( $(type).val() === "city") {
let coordinate = data.features[i].geometry.coordinates;
let lng = coordinate[0];
let lat = coordinate[1];
map.setView([lng, lat], 13);
console.log("ajax and for loop have been activated");
console.log(coordinate);}
};
$("#ristoranti").prop("disabled", false);
}, 1000);
}
});
};
I'm doing the debugger and get many undefined values:
I would do something like that:
if (typeof data.features[0] !== 'undefined') {
let coordinate = data.features[0].geometry.coordinates;
var latlng = L.latLng(coordinate.reverse());
map.flyTo(latlng, 12)
}
Be sure to have something in your array
Get data from the first item since it should be the correct one in most case
Create a latlng with those coordinates. Be careful, sometime you need to reverse the array to have the correct position.
Use flyTo to have a smooth transition to your coordinates. 12 is the zoom level
You don't need to loop over the data since you need only one position. You can replace the for with that.
You're having two problems here:
The response from the Nominatim API is returning several search results, each of them in one GeoJSON Feature inside the response FeatureCollection. It's up to you to choose which search result you want to focus in the map (the first?), or let the user do so.
You're not aware that GeoJSON uses longitude-latitude (or x-y) coordinates, whereas Leaflet uses latitude-longitude (or y-x)
According to this page, if I plug this url into my browser, then I get I get back a nice json string.
Q: How do I get that json string into a JavaScript variable?
Do I do something like:
var x = location('https://maps.googleapis.com/maps/api/elevation/json?locations=39.7391536,-104.9847034')
To get the json, you have to make an ajax request, like $.get('url') with jquery, for example. Unfortunately, you'll have cross-domain issues.
But you can use the google maps javascript API.
var init = function() {
var elevator = new google.maps.ElevationService;
elevator.getElevationForLocations({
'locations': [new google.maps.LatLng(39.7391536,-104.9847034)]
}, function(results, status) {
if (status === google.maps.ElevationStatus.OK) {
if (results[0]) {
$("#result").text('elevation: ' + JSON.stringify(results[0]))
}
}
})
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maps.googleapis.com/maps/api/js?signed_in=true&callback=init"
async defer>
</script>
<div id="result"></div>
function currentPosition(arg) {
var svc = new google.maps.ElevationService
var param = {}
param.locations = []
param.locations[0] = new google.maps.LatLng(arg.coords.latitude,arg.coords.longitude)
svc.getElevationForLocations(param, elevationForLocations)
}
function elevationForLocations(argResponse, argStatus) {
if (argStatus === google.maps.ElevationStatus.OK) {
var response = argResponse[0] // https://developers.google.com/maps/documentation/javascript/elevation?hl=en
if (response) {
$("#result").text(JSON.stringify(response))
$('#elevation').text(response.elevation)
$('#location').text(JSON.stringify(response.location))
$('#G').text(response.location.G)
$('#K').text(response.location.K)
$('#resolution').text(response.resolution)
}
}
}
navigator.geolocation.getCurrentPosition(currentPosition);
I would like to use leaflet.draw to create outlines of regions. I have managed to get this working ok: https://www.mapbox.com/mapbox.js/example/v1.0.0/leaflet-draw/
Now I'd like to save the data for each polygon to a mysql table. Am a little stuck on how I would go about exporting the data and the format I should be doing it in.
If possible I'd like to pull the data back into a mapbox/leaflet map in the future so guess something like geojson would be good.
So you could use draw:created to capture the layer, convert it to geojson then stringify it to save in your database. I've only done this once and it was dirty but worked.
map.on('draw:created', function (e) {
var type = e.layerType;
var layer = e.layer;
var shape = layer.toGeoJSON()
var shape_for_db = JSON.stringify(shape);
});
If you want to collect the coordinates, you can do it this way:
var drawnItems = new L.FeatureGroup();
map.addLayer(drawnItems);
map.on('draw:created', function (e) {
var type = e.layerType,
layer = e.layer;
drawnItems.addLayer(layer);
var shapes = getShapes(drawnItems);
// Process them any way you want and save to DB
...
});
var getShapes = function(drawnItems) {
var shapes = [];
drawnItems.eachLayer(function(layer) {
// Note: Rectangle extends Polygon. Polygon extends Polyline.
// Therefore, all of them are instances of Polyline
if (layer instanceof L.Polyline) {
shapes.push(layer.getLatLngs())
}
if (layer instanceof L.Circle) {
shapes.push([layer.getLatLng()])
}
if (layer instanceof L.Marker) {
shapes.push([layer.getLatLng()]);
}
});
return shapes;
};
map.on('draw:created', function (e) {
var type = e.layerType;
var layer = e.layer;
var shape = layer.toGeoJSON()
var shape_for_db = JSON.stringify(shape);
});
// restore
L.geoJSON(JSON.parse(shape_for_db)).addTo(mymap);
#Michael Evans method should work if you want to use GeoJSON.
If you want to save LatLngs points for each shape you could do something like this:
map.on('draw:created', function (e) {
var type = e.layerType;
var layer = e.layer;
var latLngs;
if (type === 'circle') {
latLngs = layer.getLatLng();
}
else
latLngs = layer.getLatLngs(); // Returns an array of the points in the path.
// process latLngs as you see fit and then save
}
Don't forget the radius of the circle
if (layer instanceof L.Circle) {
shapes.push([layer.getLatLng()],layer.getRadius())
}
PS that statement may not get the proper formatting but you see the point. (Or rather the radius as well as the point ;-)
Get shares as associative array + circle radius
map.on('draw:created', function (e) {
var type = e.layerType,
layer = e.layer;
if (type === 'marker') {
layer.bindPopup('Call Point!');
}
drawnItems.addLayer(layer);
var shapes = getShapes(drawnItems);
console.log("shapes",shapes);
});
var getShapes = function (drawnItems) {
var shapes = [];
shapes["polyline"] = [];
shapes["circle"] = [];
shapes["marker"] = [];
drawnItems.eachLayer(function (layer) {
// Note: Rectangle extends Polygon. Polygon extends Polyline.
// Therefore, all of them are instances of Polyline
if (layer instanceof L.Polyline) {
shapes["polyline"].push(layer.getLatLngs())
}
if (layer instanceof L.Circle) {
shapes["circle"].push([layer.getLatLng()])
}
if (layer instanceof L.Marker) {
shapes["marker"].push([layer.getLatLng()],layer.getRadius());
}
});
return shapes;
};
For me it worked this:
map.on(L.Draw.Event.CREATED, function (e) {
map.addLayer(e.layer);
var points = e.layer.getLatLngs();
puncte1=points.join(',');
puncte1=puncte1.toString();
//puncte1 = puncte1.replace(/[{}]/g, '');
puncte1=points.join(',').match(/([\d\.]+)/g).join(',')
//this is the field where u want to add the coordinates
$('#geo').val(puncte1);
});
For me it worked this:
after get coordinates send to php file with ajax then save to db
var drawnItems = new L.FeatureGroup();
map.addLayer(drawnItems);
// Set the title to show on the polygon button
L.drawLocal.draw.toolbar.buttons.polygon = 'Draw a polygon!';
var drawControl = new L.Control.Draw({
position: 'topright',
draw: {
polyline: true,
polygon: true,
circle: true,
marker: true
},
edit: {
featureGroup: drawnItems,
remove: true
}
});
map.addControl(drawControl);
map.on(L.Draw.Event.CREATED, function (e) {
var type = e.layerType,
layer = e.layer;
if (type === 'marker') {
layer.bindPopup('');
}
drawnItems.addLayer(layer);
shape_for_db = layer.getLatLngs();
SEND TO PHP FILE enter code hereWITH AJAX
var form_data = new FormData();
form_data.append("shape_for_db",shape_for_db);
form_data.append("name", $('#nameCordinate').val());
$.ajax({
url: 'assets/map_create.php', // point to server-side PHP script
dataType: 'text', // what to expect back from the PHP script, if anything

}
});
});
map.on(L.Draw.Event.EDITED, function (e) {
var layers = e.layers;
var countOfEditedLayers = 0;
layers.eachLayer(function (layer) {
countOfEditedLayers++;
});
console.log("Edited " + countOfEditedLayers + " layers");

I would like to be able to load the Google.maps API only once for alle my pages.
Then i would like to be able to use geolocation or loading a map into a page anywhere on my web app.
The problem is that I cant figure out to seperate API loading and map initialization.
Which means i need to load the API each time I create a map.
I have referenced most of my code further down in the post but i suppose the following code is the problem.That piece of code takes care of the API Loading but at the same time it takes care of setting the initialize() function as a callback function and calling it.
var script = document.createElement("script");
script.type = "text/javascript";
script.src ="http://maps.googleapis.com/maps/api/js?key=mykey&sensor=false&callback=initialize";
document.body.appendChild(script);
How do i load the api once, lets say in the header, and then create a new map each time I go to specific page. WIthout loading the maps API again. (Note that im using Jquery mobile so my header only gets loaded one time for a session.)
I get this error:
Warning: you have included the Google Maps API multiple times on this page. This may cause unexpected errors.
Ii would like to tell you my setup.
-Im using Google Map APi v3
-I'm loading the API dynamically after the page has loaded.
-I'm using Jquery mobile, which means the page with google maps only gets partially reloaded when you visit it.
-Im using google maps for two things to show the map and for geolocation.
-I'm using the Google map api on several pages.
Im interacting with the map in 3 different places: In a header javascript see code below
A header javascript
A javascript in the body
The DIV in the body that holds the map.
Here is my code for the javascript that handles loading the API, showing the map, markers etc:

var script = document.createElement("script");

The only thing in the body of the page that has to do with the maps. Is the DIV that the map is loaded into.
<div id="map" style="width: 80%; height: 280px; margin: auto; background-color: gray">Kortet loader, vent venligst.</div> <!--alternative for full screen style="position:absolute;top:30px;bottom:50px;left:0;right:0;"-->
The API is also loaded in a common header script. Because I in general need to load it on other pages.
<script src='http://maps.google.com/maps/api/js?sensor=false'></script>
<script type="text/javascript">
$(document).ready( function () {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://maps.google.com/maps/api/js?sensor=false&callback=mynamespace.init_google_maps";
document.body.appendChild(script);
$(document).bind('pageinit', function() {
//do stuff here that happens each time a new page is loaded
});
});
});
</script>
the api is loaded once inside .ready(). you can create a new map in the callback that was passed to .bind() which is called each time a new page loads or is inserted. you can initialize the map inside mynamespace. mynamespace is a .js file included on the page
