I am creating a neighbourhood map using google maps API.I have added some locations and created markers. I want to add a search filter feature, such that the user can search those locations by their name. It should include a text input field or drop-down menu that filters the map markers and list items to locations matching the text input or selection.
The list items filtering works fine but the markers(locations) are not filtered.
So I want to ask how can I use setVisible() property to hide and display the markers in my code.
This is the filter module:
function viewModel(markers) {
var self = this;
self.filter = ko.observable(''); // this is for the search box
self.items = ko.observableArray(locations);
self.filteredItems = ko.computed(function() {
var filter = self.filter().toLowerCase();
if (!filter) {
return self.items();
} else {
return ko.utils.arrayFilter(self.items(), function(id) {
return stringStartsWith(id.title.toLowerCase(), filter);
});
}
});
This is the full code of my .js file.
var map;
var locations = [
{title: 'The Red Fort', location: {lat: 28.6562, lng: 77.2410}},
{title: 'Humayun\'s Tomb', location: {lat: 28.5933, lng: 77.2507}},

Thanks for this question :) It was an interesting exercise. I'm not sure my answer will satisfy you, because it re-initializes the map every time a filter is done. I'm not sure how to get around that, because the viewModel and the initMap method are separate. But it does what you asked for.
Modified your initMap() method to take an array parameter, holding boolean values. If the array is not defined the markers' visibility are defaulted to true
Modified the viewModel, by creating an array to hold boolean values. The array is emptied every time the viewModel is called, and the markers are spliced to hold the original values only (One of the areas I'm sure you can improve on). Inside your ko.utils.arrayFilter() method, if returned value is true, I push a true value to the array as well. At the end of the array, I call the initMap() method again, with this array as input. Now only the locations which are filtered out as true in the search will be visible on re-initializing.
While applying the bindings I provided markers variable as input to the viewModel. (I think you had already intended to do this, but forgot).
Update:
Concerning the error you're getting in the comment, it's because I replaced your lines
<script src="js/newmap.js"></script>
<script src="js/maperror.js"></script>
with an empty <script> tag and placed the entire JS code in there. To avoid confusion, I'll remove all the snippets of code I had put above and show the entire file here:

Using the Google Map APi v3 , there are style options such as :
{
featureType: 'transit.line',
elementType: 'geometry',
stylers: [
{ hue: '#fc0101' },
{ visibility: 'on' }
]
}
This works on map load, as can be seen in the API example: https://developers.google.com/maps/documentation/javascript/examples/maptype-styled-simple
I need to add a click event to show or change a certain style, for example if I change the above codes hue value on a dom event.
Example code:
// a link to test map changes
var testDiv = document.getElementById("test");
// add click event listener for map
google.maps.event.addDomListener(testDiv, 'click', showTest);
// the function for setZoom works
function showTest() {
map.setZoom(2);
}
I cannot find any documents for setting the style, there is no "set", https://developers.google.com/maps/documentation/javascript/reference#StyledMapType
There is setOptions which includes a styles property but I cannot get it to work.
An example that does not work:
// turn off transit line visibility on click
function showTest() {
map.setOptions({
styles : {
featureType: 'transit.line',
elementType: 'geometry',
stylers: [
{ hue: '#fc0101' },
{ visibility: 'off' }
]
}
});
}
Working example with zoom event (just zooms out map):
http://codepen.io/anon/pen/yfGxm
Non Working example with style event (this is set to remove the
transit line shown in black): http://codepen.io/anon/pen/CphbA
Edit: The answer below is great and I didn't realize this is also documented here: https://developers.google.com/maps/documentation/javascript/styling?csw=1
http://codepen.io/jolsalazar/full/anKqG
Here the example code:
var map;
var chicago = new google.maps.LatLng(41.850033, -87.650052);
function initialize() {
var roadAtlasStyles = [
{
featureType: 'transit.line',
elementType: 'geometry',
stylers: [
{ hue: '#ff0000' },
{ visibility: 'on' },
{ lightness: -70 }
],
enableCloseButton: true,
visible: false
}
];
var mapOptions = {
zoom: 12,
center: chicago,
mapTypeControlOptions: {
mapTypeIds: [google.maps.MapTypeId.ROADMAP, 'usroadatlas']
}
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
var styledMapOptions = {
name: 'US Road Atlas'
};
var usRoadMapType = new google.maps.StyledMapType(
roadAtlasStyles, styledMapOptions);
map.mapTypes.set('usroadatlas', usRoadMapType);
map.setMapTypeId('usroadatlas');
google.maps.event.addDomListener(document.getElementById('test'), 'click', function() {
map.setMapTypeId(google.maps.MapTypeId.ROADMAP);
});
}
jQuery(document).ready(function () {
google.maps.event.addDomListener(window, 'load', initialize);
});
For me, map.setOptions() works well for setting styles.
I think you forgot the [ ] brackets.
You can change map style as followed:
// turn off transit line visibility on click
function showTest() {
var myStyle =[{
featureType: 'transit.line',

Hi Everybody!
I am trying to create a Custom Styled Google map using API v3. The map will eventually go on the following Wordpress page (310px x 537px blank space on right side of page): http://www.flatschicago.com/edgewater-chicago-apartments/
I have copied the JavaScript/HTML code from the Google Maps Javascript API v3—Simple styled maps page, and have change the color scheme to fit my websites overall theme. I have managed to format the code with the colors that I want, and I have managed to format the size of the map so it fits the space designated on my web page.
Here are the 3 things that I am having issues with:
I want to add 5+ custom plot markers to the map. Where do I add this code?
I want the street labels to appear on the map. Where do I add this code?
I tried adding the code in to my Wordpress page, but I did not work. Is there a certain part of the JavaScript/HTML code that I should only be adding?
Here is the code that I have so far.
<html>
<head>
<title>Simple styled maps</title>
<style>
html, body, #map-canvas {
height: 100%;
margin: 0px;
padding: 0px
}
</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
var map;
var edgewater = new google.maps.LatLng(41.987245, -87.661233);
var MY_MAPTYPE_ID = 'custom_style';
function initialize() {
var featureOpts = [
{
stylers: [
{ hue: '#3b3d38' },
{ visibility: 'simplified' },
{ gamma: 0.5 },
{ weight: 0.5 }
]
},
{
featureType: 'poi.business',
elementType: 'labels',
stylers: [
{ visibility: 'off' }
]
},
{
featureType: 'water',
stylers: [
{ color: '#3b3d38' }
]
}
];
var mapOptions = {
zoom: 12,
center: edgewater,
mapTypeControlOptions: {
mapTypeIds: [google.maps.MapTypeId.ROADMAP, MY_MAPTYPE_ID]
},
mapTypeId: MY_MAPTYPE_ID
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
var styledMapOptions = {
name: 'Custom Style'
};
var customMapType = new google.maps.StyledMapType(featureOpts, styledMapOptions);
map.mapTypes.set(MY_MAPTYPE_ID, customMapType);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body onload='intialize()'>
<div id="map-canvas" style='width:310px; height:537px;'></div>
</body>
</html>
1) Adding 5+ Custom Plot Markers
The code I am referring to is from the following page: page link.
I understand that I need to add a marker image and long/lat for each location, but when I try and copy and paste this code into the code that I already have created, the map doesn't work. Where am I supposed to be copying and pasting this code? Do it go inside the function initialize() code? Or is it its own function? Very confused.
2) Adding Street Labels
The code I am referring to is from the Google Maps Javascript API v3—Styled Maps page.
All I want to do is to be able to see the street labels on the map. The code I am referring to is this. I tried putting this in to my code, but again, it didn't work. Is there a simply label like 'roads,' 'on' that gets these labels to work?
var styleArray = [
{
featureType: "all",
stylers: [
{ saturation: -80 }
]
},{
featureType: "road.arterial",
elementType: "geometry",
stylers: [
{ hue: "#00ffee" },
{ saturation: 50 }
]
},{
featureType: "poi.business",
elementType: "labels",
stylers: [
{ visibility: "off" }
]
}
];
3) Add code to Wordpress page
The map will eventually go on the /edgewater-chicago-apartments/ pahe.
The space that I left for the map is labeled
<td class="neighborhood-map" rowspan="5"></td> :
If someone could please help me with this, I will be forever grateful. I feel like I am so close, yet these three things are holding me up and it is very frustrating. Anyone?
You need to have actual data (JSON format) to add the markers. For example:
// yourJsonData = data in valid JSON format
for ( i = 0; i < yourJsonData.length; i++ ) {
var latlng = new google.maps.LatLng(yourJsonData[ i ].lat, yourJsonData[ i ].long);
var marker = new google.maps.Marker({
map: map,
icon: yourURL + '/path-to-custom-markers/' + yourJsonData[ i ].icon,
position: latlng,
title: yourJsonData[ i ].title,
html: '<div class="info-window">Your window text</div>'
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(this.html);
infowindow.setOptions({maxWidth: 800});
infowindow.open(map, this);
});
}
This code loops an array (yourJsonData) that has values for latitude, longitude, etc.
