Display multiply markers in the map - javascript

so i works in a geolocation project(asp.net MVC4), i have many positions in my database and i want to show it in my map, my problem that the script just show the first position, this is my script:
var checkpoints = [];
function setMarkers(map, locations) {
for (var i = 0; i < locations.length; i++)
{
var place = locations;
for (var i = 0; i < place.length; i++)
{
var points = new google.maps.LatLng(place[i][1], place[i][2]);
checkpoints.push(points);
}
var check = checkpoints[0];
var index = 0;
for (var j = 0; j < checkpoints.length; j++)
{
check = checkpoints[j];
index = j;
var myLatLng = new google.maps.LatLng(place[index][1], place[index][2]);
var marker = new google.maps.Marker
(
{
position: myLatLng,
map: map,
title: place[index][0],
zIndex: place[index][3]
}
);
}
}
return marker;
}
so please if someone have any solution or idea i will be very appreciate.
Thanks everyone #david #Beetroot-Beetroot #razzak my script works fine now, this is my new script :
var checkpoints = [];
function setMarkers(map, locations) {
for (var i in locations) {
var points = new google.maps.LatLng(locations[i][1], locations[i][2]);
checkpoints.push(points);
var marker = new google.maps.Marker({
map: map,
position: points,
title: locations[i][0],
zindex: locations[i][4]
});
}
}
Update :
my script works fine but i have a small problem in my event, when i dblclick on a marker it should show his title but it just show me the title of the last marker :
var checkpoints = [];
function setMarkers(map, locations) {
for (var i in locations) {
var points = new google.maps.LatLng(locations[i][1], locations[i][2]);
checkpoints.push(points);
var marker = new google.maps.Marker({
map: map,
position: points,
title: locations[i][0],
zindex: locations[i][4],
});
//this is my event
google.maps.event.addListener(marker, 'dblclick', function () {
alert("I am marker " + marker.title);
});
}
}

I have simplified your code
function setMarkers(locations) {
for(var i in locations) {
var points = new google.maps.LatLng(locations[i][1].lat,locations[i][2].lng);
checkpoints.push(points);
var marker = new google.maps.Marker({
map:map,
position: points,
icon: 'myicon.png',//
title: locations[i][0],
zindex: locations[i][4]
});
}
}

Mohammadov, you are making it more complicated than it needs to be.
Try this :
function setMarkers(map, locations) {
for(var i=0; i<locations.length; i++) {
var loc = locations[i];
loc[4] = new google.maps.Marker({
position: new google.maps.LatLng(loc[1], loc[2]),
map: map,
title: loc[0],
zIndex: loc[3]
});
}
}
The map should then show the markers, and each member of the locations array should be augmented with a reference to its marker, as element [4].

the two loops inside the main loop are causing problems, they are unnecessary and can be avoided. also return marker at the end of the loop will return only the last one, you can remove it as well:
var checkpoints = [];
function setMarkers(map, locations) {
for (var i=0; i<locations.length; i++)
{
var place = locations[i],
myLatLng = new google.maps.LatLng(place[1], place[2]),
marker = new google.maps.Marker
(
{
position: myLatLng,
map: map,
title: place[0],
zIndex: place[3]
}
);
checkpoints.push({"point": myLatLng, "marker": marker});
}
}
The checkpoints now should have an array of LatLng and marker of each place.

Google Maps: Select previous Marker on Polyline

I'm doing an application with google maps API that have a JSON with the marker's coordinates. Then I draw polylines between the markers. I also implemented a function with a onclick event that creates a new marker inside the polyline. This marker has to show information of the previous marker in the polyline (the one taked of the JSON, not a clicked one). But I don't know how to take the previous vertex(marker) of a selected polyline.
Code:
(function() {
window.onload = function() {
var options = {
zoom: 3,
center: new google.maps.LatLng(37.09, -95.71),
mapTypeId: google.maps.MapTypeId.HYBRID,
noClear: true,
panControl: true,
scaleControl: false,
streetViewControl:false,
overviewMapControl:false,
rotateControl:false,
mapTypeControl: true,
zoomControl: false,
};
var map = new google.maps.Map(document.getElementById('map'), options);
// JSON
$.getJSON("loc.js", function(json) {
console.log(json);
});
//Marker type
var markers = [];
var arr = [];
var pinColor = "FE7569";
var pinImage = new google.maps.MarkerImage("http://labs.google.com/ridefinder/images/mm_20_red.png" + pinColor,
new google.maps.Size(21, 34),
new google.maps.Point(0,0),
new google.maps.Point(10, 34));
// JSON loop
for (var i = 0, length = json.length; i < length; i++) {
var data = json[i],
latLng = new google.maps.LatLng(data.lat, data.lng);
arr.push(latLng);
// Create markers
var marker = new google.maps.Marker({
position: latLng,
map: map,
icon: pinImage,
});
infoBox(map, marker, data);
//Polylines
var flightPath = new google.maps.Polyline({
path: json,
geodesic: true,
strokeColor: '#FF0000',
strokeOpacity: 1.0,
strokeWeight: 2,
map:map
});
infoPoly(map, flightPath, data);
//Calculate polylines distance
google.maps.LatLng.prototype.kmTo = function(a){
var e = Math, ra = e.PI/180;
var b = this.lat() * ra, c = a.lat() * ra, d = b - c;
var g = this.lng() * ra - a.lng() * ra;
var f = 2 * e.asin(e.sqrt(e.pow(e.sin(d/2), 2) + e.cos(b) * e.cos
(c) * e.pow(e.sin(g/2), 2)));
return f * 6378.137;
}
google.maps.Polyline.prototype.inKm = function(n){
var a = this.getPath(n), len = a.getLength(), dist = 0;
for (var i=0; i < len-1; i++) {
dist += a.getAt(i).kmTo(a.getAt(i+1));
}
return dist;
}
}
function infoBox(map, marker, data) {
var infoWindow = new google.maps.InfoWindow();
google.maps.event.addListener(marker, "click", function(e) {
salta(data.tm);
});
(function(marker, data) {
google.maps.event.addListener(marker, "click", function(e) {
salta(data.tm);
});
})(marker, data);
}
//Create onclick marker on the polyline
function infoPoly(map, flightPath, data){
google.maps.event.addListener(flightPath, 'click', function(event) {
mk = new google.maps.Marker({
map: map,
position: event.latLng,
});
markers.push(mk);
map.setZoom(17);
map.setCenter(mk.getPosition());
});
}
function drawPath() {
var coords = [];
for (var i = 0; i < markers.length; i++) {
coords.push(markers[i].getPosition());
}
flightPath.setPath(coords);
}
// Fit these bounds to the map
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < arr.length; i++) {
bounds.extend(arr[i]);
}
map.fitBounds(bounds);
//dist polylines
distpoly = flightPath.inKm();
distpolyround = Math.round(distpoly);
};
})();
If I click in the blue arrow, I create a marker on that point of the polyline. I that marker it takes the values of the previous one.
You can use the geometry library .poly namespace isLocationOnEdge method to determine which segment of the polyline the clicked point (new marker) is on.
//Create onclick marker on the polyline
function infoPoly(map, flightPath, data) {
google.maps.event.addListener(flightPath, 'click', function(event) {
mk = new google.maps.Marker({
map: map,
position: event.latLng,
});
markers.push(mk);
map.setZoom(17);
map.setCenter(mk.getPosition());
// find line segment. Iterate through the polyline checking each line segment.
// isLocationOnEdge takes a google.maps.Polyline as the second argument, so make one,
// then use it for the test. The default value of 10e-9 for the tolerance didn't work,
// a tolerance of 10e-6 seems to work.
var betweenStr = "result no found";
var betweenStr = "result no found";
for (var i=0; i<flightPath.getPath().getLength()-1; i++) {
var tempPoly = new google.maps.Polyline({
path: [flightPath.getPath().getAt(i), flightPath.getPath().getAt(i+1)]
})
if (google.maps.geometry.poly.isLocationOnEdge(mk.getPosition(), tempPoly, 10e-6)) {
betweenStr = "between "+i+ " and "+(i+1);
}
}
(function(mk, betweenStr) {
google.maps.event.addListener(mk, "click", function(e) {
infowindow.setContent(betweenStr+"<br>loc:" + this.getPosition().toUrlValue(6));
infowindow.open(map, mk);
// salta(data.tm);
});
})(mk, betweenStr);
google.maps.event.trigger(mk,'click');
});

INITIALIZING
When you are creating those markers in the for loop, add them to a map [Data structure] that you define (empty) before the loop. In the map markers will be stored. Their keys - concatenated lat/lng.
var initial_markers = {}; //before for loop
initial_markers[data.lat+"-"+data.lng] = marker; //after each marker initialization
Count them, so you know how many there are initial_marker_count, because you cannot get length of size of a map[data structure]
DETECTION
When you have clicked on a polyline, I don't think you can get exactly the part of polyline that is clicked, so you need to get it yourself. The steps are:
Get the coordinate of click event
Loop through the markers
Take their coordinates
Check if the clicked point on the map is on the line between those two points
If is, take the first of those two points
DETECTION PSEUDOCODE
var prev_marker;
for (var i=initial_markers; i<initial_marker_count-2; i++) {
if( isPointOnLine(initial_markers[i], initial_markers[i+1], clicked_point) {
prev_marker = initial_markers[i];
break;
}
}
The only reason I am saying that this is pseudocode, is because I don't know hor to find if point is on the line between two points in Google maps. And you should write that isPointOnLine() functions. Apart from that - the idea is given. Hope You appreciate it.

Display multiple markers, variable and array problems

I try to display multiple markers on my map. I put the multiples location in adata-attribute trough my php file. Then I try to grab this information in my javascript one.
If I directly paste the coordinates, the markers appear. If I reference the data-attribute they don't. (The only difference is on the line beginning with var locations.)
This code works:
function GoogleMapsInit(){
setTimeout(function initialize() {
var emplacements = $('#iframecarte').attr("data-emplacements");
// Emplacements returns [[45.5314817,-73.1835154], [45.570004,-73.448701] ]
var mapOptions = {
zoom: 12,
center: new google.maps.LatLng(45.5580421, -73.7303025)
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var locations = [[45.5314817,-73.1835154], [45.570004,-73.448701] ];
var marker, i;
var markers = new Array();
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][0], locations[i][1]),
map: map
});
markers.push(marker);
}
}, 500);
}
This one doesn't:
function GoogleMapsInit(){
setTimeout(function initialize() {
var emplacements = $('#iframecarte').attr("data-emplacements");
// Emplacements returns [[45.5314817,-73.1835154], [45.570004,-73.448701] ]
var mapOptions = {
zoom: 12,
center: new google.maps.LatLng(45.5580421, -73.7303025)
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var locations = emplacements;
var marker, i;
var markers = new Array();
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][0], locations[i][1]),
map: map
});
markers.push(marker);
}
}, 500);
}
What is wrong with the variable locations when it references the emplacements variable so that the markers don't show?
The non-working version emplacements is a string, not an array.
Convert the string to a javascript array:
var locations = JSON.parse(emplacements);

Multiple "InfoWindow" for array of "markers" on Google Maps?

Using Google Maps API to add an infoWindow to each marker. Markers come from an array.
Although, infoWindow only shows up for the first marker, not the others. Why? Thanks.
function set_markers(array) {
var mapOptions = {
zoom: 13
}
for (var i = 0; i < array.length; i++) {
var single_location = array[i];
var myLatLng = new google.maps.LatLng(single_location[1], single_location[2]);
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: single_location[0]
});
var infowindow = new google.maps.InfoWindow({
content: ""
});
}
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent('<h3>'+this.title+'</h3>');
infowindow.open(map,this);
});
}
var infowindow = new google.maps.InfoWindow();
function set_markers(array) {
var mapOptions = {
zoom: 13
};
for (var i = 0; i < array.length; i++) {
var single_location = array[i];
var myLatLng = new google.maps.LatLng(single_location[1], single_location[2]);
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: single_location[0]
});
google.maps.event.addListener(marker, 'click', function () {
infowindow.setContent('<h3>' + this.title + '</h3>');
infowindow.open(map, this);
});
}
}
This is untested since you didn't post a MCVE.

Info bubble always shows up on the last marker [duplicate]

This question already has answers here:
Closed 10 years ago.
Possible Duplicate:
Google Maps - Multiple markers - 1 InfoWindow problem
I'm making a map where I plot some towns and places.
As you will see, when you click on a marker, you are redirected to the corresponding page. But now I would like to put the link and some other information in an info bubble popover. So, I've edit my code to this:
function setMarkers(map, locations) {
for (var i = 0; i < locations.length; i++) {
var beach = locations[i];
var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
var infobulle = new google.maps.InfoWindow({content: beach[4], position: myLatLng});
var marker = new google.maps.Marker({position: myLatLng, map: map, title: beach[0], zIndex: beach[3], clickable: true, icon: beach[5],});
marker[i] = marker;
google.maps.event.addListener(marker[i], 'click', function() {
infobulle.open(map, marker);
});
}
}
But as you can see here the info bubble stays "blocked" on the last location. I really don't know how to sort this.
I have the same result with this :
function setMarkers(map, locations) {
for (var i = 0; i < locations.length; i++) {
var beach = locations[i];
var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
var infobulle = new google.maps.InfoWindow({content: beach[4]});
var marker = new google.maps.Marker({position: myLatLng, map: map, title: beach[0], zIndex: beach[3], clickable: true, icon: beach[5]});
google.maps.event.addListener(marker, 'click', function() {
infobulle.open(map, marker);
});
}
Last version :
function setMarkers(map, locations) {
for (var i = 0; i < locations.length; i++) {
processBeach(locations[i]);
}
}
function processBeach(beach) {
var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
var infobulle = new google.maps.InfoWindow({content: beach[4]});
var marker = new google.maps.Marker({position: myLatLng, map: map, title: beach[0], zIndex: beach[3], clickable: true, icon: beach[5]});
google.maps.event.addListener(marker, 'click', function() {
infobulle.open(map, marker);
});
}
You are using the marker variable for two different purposes it seems. One is as a single marker, and one as an array of markers. But you don't need an array of markers, if you use closures. Try this:
function setMarkers(map, locations) {
for (var i = 0; i < locations.length; i++) {
(function(beach) {
var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
var infobulle = new google.maps.InfoWindow({content: beach[4], position: myLatLng});
var marker = new google.maps.Marker({position: myLatLng, map: map, title: beach[0], zIndex: beach[3], clickable: true, icon: beach[5]}))
google.maps.event.addListener(marker, 'click', function() {
infobulle.open(map, marker);
});
}(locations[i]));
}
}
By the way you also had a spurious comma at the end of the options array for google.maps.Marker which will cause problems in some browsers.
EDIT
If you don't want to use closures, this is equivalent:
function processBeach(beach) {
var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
var infobulle = new google.maps.InfoWindow({content: beach[4], position: myLatLng});
var marker = new google.maps.Marker({position: myLatLng, map: map, title: beach[0], zIndex: beach[3], clickable: true, icon: beach[5]}))
google.maps.event.addListener(marker, 'click', function() {
infobulle.open(map, marker);
});
}
function setMarkers(map, locations) {
for (var i = 0; i < locations.length; i++) {
processBeach(locations[i]);
}
}
Have a look at my jSFiddle here. The code you are missing is
On Click you need to fetch the current infoWindow from the map and then update it with new information
If you want to keep windows open and close when people want to close then you have to set a toggle kind of variable so each window will be created on click and then when someone click on close it will go away. But i think you only need to complete first part.
The code you should look in my fiddle is from line 120 to 150 which does check for infowindow if it exists and then do open the same window on new marker so it moves from old marker and go to new. if you keep creating new windows the old ones will not close magically.
var map = $(this).gmap3("get"),
infowindow = $(this).gmap3({get:{name:"infowindow"}}); // Get current info window
if (infowindow){ // if infoWindow is there then use it else create new
infowindow.open(map, marker);
infowindow.setContent(context.data.ht);
jQuery("#customPopup").html(context.data.ht);
jQuery("#customPopup").show(500);
} else {
$(this).gmap3({
infowindow:{
anchor:marker,
options:{content: context.data.ht}
}
});
jQuery("#customPopup").html(context.data.ht);
jQuery("#customPopup").show(500);
}

Changing to a capital W was not enough for me. Only one location was being opened. I tested your code with two points:
MarkLat = [];
MarkLong = [];
Display = [];
MarkerTitle= [];
MarkLat[0] = 0;
MarkLong[0] = 0;
Display[0] = { content: "hi" };
MarkerTitle[0] = "hello";
MarkLat[1] = 10;
MarkLong[1] = 10;
Display[1] = { content: "hi 2" };
MarkerTitle[1] = "hello 2";
I'm guessing you only want one InfoWindow on the screen at any given time. Then, a single InfoWindow should be declared, with the contents kept inside the marker, and have the contents change as the marker is clicked.
var infoWindow = new google.maps.InfoWindow();
for (var i = 0, length = Display.length; i < length; i++) {
var latLng = new google.maps.LatLng(MarkLat[i],MarkLong[i]);
// Creating a marker and putting it on the map
var marker = new google.maps.Marker({
position: latLng,
map: map,
title: MarkerTitle[i],
infoWindowContent: Display[i]
});
// Notice I used the 'this' keyword inside the listener
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent(this.infoWindowContent.content);
infoWindow.open(map,this);
});
}
The alternative, having many InfoWindows pop up, needs a change to click listener, so that a reference to each individual InfoWindow is preserved. This effect is accomplished with an anonymous function wrapped around the infoWindow.open function (a new function scope is created).
for (var i = 0, length = Display.length; i < length; i++) {
var latLng = new google.maps.LatLng(MarkLat[i],MarkLong[i]);
var infoWindow = new google.maps.InfoWindow(Display[i]);
// Creating a marker and putting it on the map
var marker = new google.maps.Marker({
position: latLng,
map: map,
title: MarkerTitle[i]
});
google.maps.event.addListener(marker, 'click', (function(infoWindow) {
return function() {
infoWindow.open(map,this);
}
})(infoWindow));
}
infowindow != infoWindow
You just have declared it with a capital, trying to use it without
