Filtering gmap markers, how? - json

How can I filtering gmap markers from Json file?
$(function() {
demo.add(function() {
$('#map_canvas').gmap({'disableDefaultUI':false, 'callback': function() {
var self = this;
$.getJSON('demo.asp', function (data) {
$.each( data.markers, function(i, marker) {
self.addMarker({ 'position': new google.maps.LatLng(marker.latitude, marker.longitude), 'bounds':true } ).click(function() {
self.openInfoWindow({ 'content': marker.content }, this);
});
});
});
}});
}).load();
});

$(function() {
demo.add(function() {
$('#map_canvas').gmap({'disableDefaultUI':false, 'callback': function() {
var self = this;
$.getJSON('demo.asp', function (data) {
$.each( data.markers, function(i, marker) {
if(marker!="filtered data"){
self.addMarker({ 'position': new google.maps.LatLng(marker.latitude, marker.longitude), 'bounds':true } ).click(function() {
self.openInfoWindow({ 'content': marker.content }, this);
}
});
});
});
}});
}).load();
});
You can filter it there, or filter it on the logic that gets the json data.

Fetch ISO-3166-2 code from Google Maps API. Is it possible?

I need to match locations recorded with their coordinates (latitude/longitude) to the visitor's selection from an interactive map using region codes (ISO-3166-2).
Anyone has a take on this please? Not too sure how to go about it and/or if it's possible.
This is code for fetching region codes(ISO-3166-2) using google maps.

Calling multiple JSON data with Jquery Deferred

I am trying to get multiple JSON data with deferred object. I have JSON files for individual days. In each individual day, I have data for points, lines and polygons. I have jQueryUI Sliders to visualise for individual days. For example, if the slider has value of 1, only the day1 data (points, lines and polygons) need to be visualised, and for day2, all points, lines and polygons relating to day2 only should be visualised and so on.
I don't know what is problem with my code but it is not serving the required data. Latest data/merged data is shown.
Help me out here.

I solved the problem by clearing the map layer every time I am to add new one.
map.eachLayer(function (layer) {
if (layer.feature) {
map.removeLayer(layer);
}
});

How to add multiple markers on mobile Google Map and display the content when click?

hello i am working on the phonegap apps which can display the location markers on google map.
It is supposed to have a detail box pop up when i click on the marker, but it does not function.
can anyone help me to correct the code?
many thanks

There is a easier way to use Google Maps api,https://github.com/HPNeo/gmaps. And what you need almost like this,http://hpneo.github.com/gmaps/examples/markers.html, you click the marker and the detail info shows

jquery-ui-map load json and update markers

I've searched all over the web and SO, but I couldn't figure this out.
Here's the problem:
I'm using the below demo from jquery-ui-map site to load a JSON file:
http://jquery-ui-map.googlecode.com/svn/trunk/demos/jquery-google-maps-json.html
It works fine to load my markers, but I need to refresh its content every 30 seconds and grab new markers.
At first I thought I would just call the function again, but that left the markers there. After some research I found out I needed to clear the markers (not so easy on V3, but I was able to to do) but the issue is that I can't get the markers to show again.
If I use the destroy function, then I'm able to reload new markers and remove the old ones, but that causes the map to blink. When I try to clear markers then no new markers are shown.
Any help is greatly appreciated.
Below is my code:
<script type="text/javascript">
function mapTest() {
$('#map_canvas').gmap('destroy');
//clearMap();
demo.add(function() {
$('#map_canvas').gmap({'disableDefaultUI':true, 'callback': function() {
var self = this;
$.getJSON( 'json/demo.json?'+ new Date().getTime(), function(data) {
$.each( data.markers, function(i, marker) {
self.addMarker({ 'position': new google.maps.LatLng(marker.latitude, marker.longitude), 'bounds':true } ).click(function() {
self.openInfoWindow({ 'content': marker.content }, this);
});
});
});
}});
}).load();
}
function clearMap(){
$('#map_canvas').gmap('clear', 'markers');
}
mapTest();
setInterval(mapTest, 30000 );
</script>
Cheers.
Your map initialization function is inside the mapTest() function - which you call over an over again every 30 seconds with setInterval.
That is wrong, because you are essentially reloading the map( you destroy it and then recreate it again every 30 seconds ), and that is why it blinks.
Place the map initialization outside the mapTest(), but clear and retrieve new markers from within the mapTest()
Update:
var mapOptions = {
disableDefaultUI: true
// add more options if you wish.
};
function mapTest() {
$('#map_canvas').gmap('clear', 'markers'); // clear old markers
$.getJSON( 'json/demo.json?'+ new Date().getTime(), function(data) {
$.each( data.markers, function(i, marker) {
var self = this;
self.addMarker({ 'position': new google.maps.LatLng(marker.latitude, marker.longitude), 'bounds':true } ).click(function() {
self.openInfoWindow({ 'content': marker.content }, this);
});
});
});
}
$(function(){
$('#map_canvas').gmap(mapOptions, function(){
$.getJSON( 'json/demo.json?'+ new Date().getTime(), function(data) {
$.each( data.markers, function(i, marker) {
var self = this;
self.addMarker({ 'position': new google.maps.LatLng(marker.latitude, marker.longitude), 'bounds':true } ).click(function() {
self.openInfoWindow({ 'content': marker.content }, this);
});
});
});
});
setInterval(mapTest, 30000 );
});
I found a Solution to update markers without reloading the map. Try this code...
$(document).ready(function() {
var $map = $('#map_canvas');
App.drawMap($map);
setInterval(function() {
$('#map_canvas').gmap('clear', 'markers');
App.drawMap($map);
},10000);
});
var App = {
drawMap: function($divMap) {
Http.doAjaxGetJson('../../js/testjson.json', function(data) {
for (var k in data.gpsData) {
$divMap.gmap({ 'center': new google.maps.LatLng(data.gpsData[k].latitude,data.gpsData[k].longitude),'zoom':15, 'callback': function() {}});
$divMap.gmap('addMarker', {
'title':data.obj.name,
'position': new google.maps.LatLng(data.gpsData[k].latitude, data.gpsData[k].longitude),
'bounds': false,
}).click(function() {
var $_obj = $(this);
});
}
});
}
};
By this code markers will update in every 10 seconds..

MooDialog.Request add Event

How can I add a close event to MooDialog.Request?
Update:
There is my code:
window.addEvent('domready', function(){
$('xyz').addEvent('click', function(e) {
e.stop();
var reqDialog = new MooDialog.Request(url,
{view:'show'},
{
size: {
width: 460,
height: 375,
'zIndex':20
}
}
);
reqDialog.setRequestOptions({
onClose: function(){
alert('closed');
}
});
});
});
It's pretty simple:
//Request => new MooDialog.Request(url[, RequestOptions, options]);
var reqD = new MooDialog.Request('URL',null,{
onClose: function(){
alert('closed');
}
});
doc
Edit your code need to be updated this way:
window.addEvent('domready', function(){
$('xyz').addEvent('click', function(e) {
e.stop();
var reqDialog = new MooDialog.Request(url, null, {
class:'dialogClass',
autoOpen: false,
onClose: function(){
alert('closed');
}
});
reqDialog.open();
/*
if you want to add some custom requestOptions, you need to do i.e.:
reqDialog.setRequestOptions({
onRequest: function(){
reqDialog.setContent('loading...');
}
}).open();
*/
});
and you need some css to define the style of the dialog by dialogClass:
.dialogClass{
width:460;
height:375;
z-index:20;
}
