So I have a map using the google map api and I'm trying to change the water color on a button click.
I've been struggling with this one for a while now.
I initialised the map variable outside of the initMap function but that didn't seem to change anything.
var map;
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
center: {
lat: 40.674,
lng: -73.945
},
zoom: 12,
styles: [
{
featureType: 'water',
elementType: 'geology',
stylers: [{color: '#17263c'}]
}
]
});
}
function showTest() {
var myStyle =[{
featureType: 'water',
elementType: 'geometry',
stylers: [
{ color: '#fc0101' }
]
}];
map.setOptions({styles: myStyle});
}
Even though you initialised a map variable outside your initMap function, the fact you then declare a map variable inside that function prefixed with var, makes it local to just that function.
Change that to:
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
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}},

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:

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.

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.
I am double checking, really, as I think the answer is no: Can I hide bodies of water which aren't seas/oceans, i.e. lakes. A client is commenting that these smaller bodies of water make the maps look "complicated".
Here's my styling rules:
fsdStyles = [
{
featureType: 'all',
stylers: [
{visibility: 'off'},
{hue: '#00162b'}
]
},
{
featureType: 'administrative.country',
stylers: [
{ visibility: 'on' }
]
},
{
featureType: 'water',
stylers: [
{ hue: '#002f56' },
{ saturation: 85 },
{ lightness: -84 },
{ visibility: 'simplified' }
]
}
];
No, you cannot turn the features you describe off. And there is only the single feature type: water, there are no sub-types, so there is no real way to style lakes in one way and oceans in another.
This is a view in a rails app - unfortunately I am getting an error I cannot fix ("Uncaught Syntax Error: Unexpected end of input"). Although I'm sure the answer is simple, adding an extra }); does not solve the problem.
Anyone have any thoughts as to where I may have forgotten to close something out?
Thanks!

From the use of console.log(), I take it you're not testing in IE right now. But if the error was in IE, I would remove the trailing commas from the lines which say:
{ visibility: "simplified" },
In cases like this, the best debugging technique I know is doing a "binary search". Remove half the code (of course, don't just chop it off in a place which will leave unmatched brackets or braces), try running it in a browser, and see if there is still a syntax error. Repeat until you narrow it down to a small section of code.
