Google Maps API Click Point Marker (not custom)
(1 answer)
Closed 8 years ago.
i did not request the place library in the google map script, but poi information by Google is still showing up. I saw other examples where those poi are not shown. What is the right configuration to hide those poi?

Here's how I've done this before:
var myStyles =[
{
featureType: "poi",
elementType: "labels",
stylers: [
{ visibility: "off" }
]
}
];
var myOptions = {
zoom: 10,
center: new google.maps.LatLng(54.42838,-2.9623),
mapTypeId: google.maps.MapTypeId.ROADMAP,
styles: myStyles
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

How can my google maps api iterate over an object in a different script?

When I put my object (points) in the same script as the google maps API it works fine. But when I move the object to its own script on top it says "points is not defined".
I need to have the object in the top script (its actually coming from a database).
See working demo: https://price-points.web.app/
This is a Svelte project.
<script>
export const prerender = true;
let showMap = false;
//How can I make this work without the setTimeout?
setTimeout(function(){showMap = !showMap}, 1);
</script>
<!-- Google Maps API -->
<div>
<div id="map"></div>
<script>
//If points object is here it works fine.
//If points is defined in top script it says "points is not defined"
//My ACTUAL points object comes from a database and needs to be in top script.
let points = {
sanFrancisco: {
lat: 37.7749,
lng: -122.4194,
price: 123.45
},
losAngeles: {
lat: 34.0522,
lng: -118.2437,
price: 567.89
}
}
function initMap() {
const california = {lat: 36.7783,lng: -119.4179};
const map = new google.maps.Map(document.getElementById("map"), {
zoom: 7,
center: california,
});
Object.values(points).forEach(({ lat, lng, price }) => {
const marker = new google.maps.Marker({
position: {lat: lat, lng: lng},
map: map,
label: `$${price}`,
icon: { url: 'https://i.imgur.com/ECXgKpB.png', scaledSize: new google.maps.Size(60,35), labelOrigin: new google.maps.Point(30, 15)}
});
});
}
window.initMap = initMap;
</script>
{#if showMap}
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap&v=weekly" defer async></script>
{/if}
</div>
<style>
#map {
height: 800px;
width: 100%;
}
</style>
The script in Svelte components is scoped (it is implicitly a module which requires import/export), you have to set window.points to make variables available globally.
Note that in SvelteKit you cannot access window during server-side rendering, so you probably should move the assignment into onMount. In general you should not have multiple script tags in the first place, maybe you are fighting the wrong problem.

Fusion table api map not showing styles after table update

I'm relatively new to the Fusion Tables Api and I am trying to create a simple web app using Fusion Tables and Google Maps Api. The application will be used about three times a day and each time a new set of data will be added to the table, replacing the old entries with new ones.
So far, the application is working as expected, except for when changes are made to the fusion table. When I add or delete multiple rows from the table manually through the Fusion Table page and then return to my app, I notice that the styles stop working properly, and in many cases do not appear at all; however, after about an hour everything starts working normally again.
The code I use for creating the styles is this,
layer = new google.maps.FusionTablesLayer({
query: {
select: "geometry",
from: '11CIZUlNjBPiOM1Y4pDUP_Mn9TxkqF0etfpWhi5c'
},
styles:[
{
polygonOptions:{
fillColor: '#FF0000',
fillOpacity: 0.05
}
},
{
where: "Location LIKE 'PERDUE'",
polygonOptions: {
//fillColor: '#0000FF'
fillOpacity:0.2
}
},
{
where: "GeoBlock = 'AC1C'",
polygonOptions: {
//fillColor: '#0000FF'
fillOpacity:0.8
}
},
{
where: "Location = 'BENGOUGH'",
polygonOptions: {
//fillColor: '#0000FF'
fillOpacity:0.99
}
}]
});
layer.setMap(map);
I've researched a bit to see if anyone else is having similar issues, and the closest thing that I've come across that is similar to the problem I am having is that it may be a cache issue with the browser, but I've tested this scenario with multiple machines at the same time and have been getting the same result and I've also added the no-cache tag to my code to prevent the browser from caching the styles. I'm not sure if this is an Api issue or something else. I will appreciate any suggestions on how to approach this problem.
Thanks,
It's an API-issue, the tiles created to display the layers will also be cached by google.
What you can do: modify the queries, so that it still fetches the same results, but the String-representation for the query is different. This should speed-up the tile-update(and prevent from client-side caching).
Taking your code it could be done like this:
var and=' Location does not contain "'+new Date().getTime()+'"';
layer = new google.maps.FusionTablesLayer({
query: {
select: "geometry",
from: '11CIZUlNjBPiOM1Y4pDUP_Mn9TxkqF0etfpWhi5c',
where: and
},
styles:[
{
polygonOptions:{
fillColor: '#FF0000',
fillOpacity: 0.05
}
},
{
where: "Location LIKE 'PERDUE' and "+and,
polygonOptions: {
//fillColor: '#0000FF'
fillOpacity:0.2
}
},
{
where: "GeoBlock = 'AC1C' and "+and,
polygonOptions: {
//fillColor: '#0000FF'
fillOpacity:0.8
}
},
{
where: "Location = 'BENGOUGH' and "+and,
polygonOptions: {
//fillColor: '#0000FF'
fillOpacity:0.99
}
}]
});
Instead of using new Date().getTime() I would suggest to use(when available) e.g. the timestamp of the last modification so that the cached tiles still may be used when no update has been done.

How to preserveViewport with Drive KML file embed in google maps api v3

EDIT: Solved:
var opt = { minZoom: 6, maxZoom: 9 };
map.setOptions(opt);
I'm a cut-and-paste coder and while I intend on learning the syntax better, I'm on a deadline for now so I'm asking for help. I have googled extensively and while there are solutions to my problem, I haven't found one that works for me. My KML file is hosted on Google Drive so instead of a file url there is a driveFileId.
If you want to preserveViewport, you normally just add it to the layer object and set it to 'true'. However my KML file won't let me override its default zoom level where the bounds fit the screen no matter how I write it. Can someone help? This is the working object:
var layer = new google.maps.KmlLayer({
driveFileId: "0Bexampleg"});
layer.setMap(map);
EDIT: Here's the whole thing. Perhaps you can see if there are redundancies or contradictions that are causing this.
<!DOCTYPE html>
<html<!DOCTYPE html>
<html>

<script type="text/javascript" src="http://maps.google.com/maps/api/js?key=Aexamplekey0&sensor=true"></script>
<style>
#map {
width: 310px;
height: 410px;
}
</style>
<script>
window.onload = function () {
var latlng = new google.maps.LatLng(53.385873, -1.471471);
var styles = [
{
//whatever
}
]
var myOptions = {
zoom: 15,
disableDefaultUI: false,
styles: styles
},
map = new google.maps.Map(document.getElementById('map'), myOptions);
var layer = new google.maps.KmlLayer({
driveFileId: "0Bexampleg"});
layer.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map"></div>
</body>
</html>
Based on the current release API documentation, you should be able to set the preserveViewport option in the object you instantiate:
var layer = new google.maps.KmlLayer({
driveFileId: "0Bexampleg",
preserveViewport: true});
layer.setMap(map);
Without further information, such as a URL to your KML data, information about your map center and zoom, there's not much further that can be said.
GOT IT!
Here it is:
var opt = { minZoom: 11, maxZoom: 15 };
map.setOptions(opt);
And then in your the myOptions object you set your default zoom. Solution found here: Google Maps v3 - limit viewable area and zoom level
thanks to #ChrisV. I don't know why but the KML Layer won't allow any permutation of the original preserveViewport code.

Styles not being recognized when attempting to change with a google fusion table query

I have an otherwise working application at Sample Web Site
I would like to change the display of the selected line from the default thin red line to a much thicker green (or red) line.
When I changed the following code in the map.js file from
// Google Fusion LineFeat table
var linLayer = new google.maps.FusionTablesLayer({
query: {
select: 'name',
from: linTableId,
where: idStr,
},
map: GlobalMap
});
to add the styles section as shown, nothing changes in the display
// Google Fusion LineFeat table
var linLayer = new google.maps.FusionTablesLayer({
query: {
select: 'name',
from: linTableId,
where: idStr,
styles: [{
polylineOptions: {
strokeColor: "#00FF00",
strokeWeight: "12"
}
}]
},
map: GlobalMap
});
Can someone provide me some direction on what I might be doing wrong? I get these same results if I comment out the call to the zoom.js functions that zoom the map into the specific project.
The styles option doesn't go in the query:
// Google Fusion LineFeat table
var linLayer = new google.maps.FusionTablesLayer({
query: {
select: 'name',
from: linTableId,
where: idStr
},
styles: [{
polylineOptions: {
strokeColor: "#00FF00",
strokeWeight: "12"
}
}],
map: GlobalMap
});
BTW - in your "Sample Map" you are overwriting linLayer with the layer for AreaFeat, you probably don't want that.

disable clickable landmark on google map

I'm using google map API v3. I want to disable click action on default google landmark/poi. For example, when I zoom to UCLA, the school icon shows up (that's fine) but I don't want user to click and view details of that location. Which API function should I use?
Google has exposed an option for this. See clickableIcons of google.maps.MapOptions in the docs.
Example initialization code:
map = new google.maps.Map(document.getElementById('map'), {
clickableIcons: false
});
add this option to mapOption
clickableIcons: false
this is more options i think you will
draggable: true, // this is for disable the Draggable
disableDefaultUI: true, // this for disable Default UI
fullscreenControl: false, // this is for disable Full Screen
scrollwheel: true, // this is for disable Scroll Wheel
disableDoubleClickZoom: false, // this is for disable Double Click Zoom
draggableCursor:'crosshair',// this is for cursor type
draggingCursor:'move', // this is for dragging cursor type
minZoom: 3, // this is for min zoom for map
maxZoom: 18 , // this is for max zoom for map
//note : max, min zoom it's so important for my design.
zoom: 14, // this is to make default zoom
clickableIcons: false, // this is to disable all labels icons except your custom infowindow or Infobox.
I encountered this same problem.
Google appears to have recently changed their api to make the base map labels "clickable" and there is not yet a simple API call to disable their clickablility.
http://groups.google.com/group/google-maps-js-api-v3/browse_thread/thread/f1ac9ad4da3606fe
I would like to see google add a simple map option like this, but alas it doesn't exist yet
var opts = { clickableLabels:false };
var map = new maps.google.com.map(div,opts);
The following solution works, but because it relies on custom styled map tiles, free maps are limited to (2,500 maps loads per day) - See Google Maps FAQ.
function initialize() {
// For more details see
// http://code.google.com/apis/maps/documentation/javascript/styling.html
var noPOILabels = [
{
featureType: "poi",
elementType: "labels",
stylers: [ { visibility: "off" } ]
}
];
// Create a new StyledMapType object, passing it the array of styles,
// as well as the name to be displayed on the map type control.
var noPOIMapType = new google.maps.StyledMapType(noPOILabels,
{name: "NO POI"});
// Create a map object, and include the MapTypeId to add
// to the map type control.
var mapOptions = {
zoom: 11,
center: new google.maps.LatLng(55.6468, 37.581),
mapTypeControlOptions: {
mapTypeIds: [google.maps.MapTypeId.ROADMAP, 'no_poi']
}
};
var map = new google.maps.Map(document.getElementById('map_canvas'),
mapOptions);
//Associate the styled map with the MapTypeId and set it to display.
map.mapTypes.set('no_poi', noPOIMapType);
map.setMapTypeId('no_poi');
}
This issue has been logged with google at:
http://code.google.com/p/gmaps-api-issues/issues/detail?id=3866
Please star and comment your needs on this issue there.
I understand that the OP wants a solution that persists the labels/icons but suspends the click events. I'm not sure this is possible; please star this issue
However, some of us are drawing shapes sans Drawing Manager and labels/icons are obstructing the additions of new points. If it meets your requirements, you can temporarily remove the icons/labels. I've found that transit, poi, and landscape all need to be toggled:
var map = new google.maps.Map(document.getElementById("map"), {});
map.poi = function(state){
var styles = [
{
"featureType": "transit",
"stylers": [
{ "visibility": "off" }
]
},{
"featureType": "poi",
"stylers": [
{ "visibility": "off" }
]
},{
"featureType": "landscape",
"stylers": [
{ "visibility": "off" }
]
}
];
this.set("styles", (state)? {} : styles );
}
And the usage:
//turn the labels/icons off
map.poi(false);
//turn them back on
map.poi(true);
I understand that this question is old, but maybe this answer will help others:
I'm not sure if this is legal, but I ended up exploring the code and made this:
$("#google-map").on("mousedown",function(){
setTimeout(function(){
disableInfoWindows();
},500);
});
function disableInfoWindows()
{
$(".gm-iw.gm-sm").parent().parent().remove();
$("[style='position: absolute; left: -2px; top: -336px; width: 59px; height: 492px; -webkit-user-select: none; border: 0px; padding: 0px; margin: 0px;']")
.parent()
.parent()
.remove();
}
It worked for me, no infoWindow showing up, while preserving all the icons. Anyone who has an idea enhancing the code is welcome, the infoWindow is showing up just a bit the first time it is about to open, after that first one, it is completely gone.
Yeah, the other solutions work but you can also want to have ability to hide/disable only part of that pins or disable ability to go to details from popups, please see my post here with some tips how you can do that CLICK
Right, to sum up, if you want to "remove" popups, you can just use:
clickableIcons: false
for map options object. But if you want to have a popup, but without "View on Google Maps" label, you can use a hacky CSS trick:
google-map {
.view-link {
display: none !important;
}
}
That was my requirements, and it works!
If you want to define which icons/pins (elements or labels, however you call it) should be visible, you can use this site to generate proper JSON with map settings: https://mapstyle.withgoogle.com/
