Updating a variable value with jQuery, based on a map click? - javascript

I am working with a Mapbox GL map, similar to something like Leaflet or OpenLayers. For this case, I have allowed a click on the map to activate a popup with text from an attribute of that element of the map. I want this click to also update a variable, img_start, which contains a key for an image in street level view. I have the following code inside my <script></script> inside the <body>. The map element is inside the <div id="map"> and the variable img_start is inside <div id="mly">. So I want a click on the map to update the img_start variable, then refresh the mly div. How can I achieve this, and what am I doing wrong?
Specific code I'm referring to:
map.on('click', function (e) {
//change img_start variable, right now just a test to see if the new value will load
img_start = 'lGQKs30MWMrNJnTjDz-2Ig';
//refresh the 'mly' div so the new start image appears
$("#mly").load(location.href + " #mly");
var features = map.queryRenderedFeatures(e.point, { layers: ['parcels-layer'] });
if (!features.length) {
return;
};
var feature = features[0];
var popup = new mapboxgl.Popup()
.setLngLat(map.unproject(e.point))
//displays the TaxIDNum of the parcel
.setHTML(feature.properties.TaxIDNum)
.addTo(map);
});
// Indicate that the symbols are clickable by changing the cursor style
map.on('mousemove', function (e) {
var features = map.queryRenderedFeatures(e.point, { layers: ['parcels-layer'] });
map.getCanvas().style.cursor = (features.length) ? 'pointer' : '';
});

How do I use the same script/key for my multiple tabs?
It looks like you are including two different versions of the same script. Instead of:
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=MY_KEY_HERE"></script>
<script type="text/javascript" src="mapapi.js"></script>
You want to choose one of those lines. I'm guessing the first one if you are making more than one API call.
I fixed this by making a new map variable in another mapapi file:mapapi0.js which I called map0. Then I needed to change #map-canvas { height: 460px }and <div id="map-canvas"></div> to a map canvas with a new id in index.html.

Issues with OpenSeaDragon overlays and tooltips in collection mode

I'm working on a image gallery based on OpenSeaDragon, and I'd like to be able to use overlays in collection mode. Based on the various examples on the OSD website (http://openseadragon.github.io/) I managed to hack together a minimal working example, but there are several issues I've not been able to fix (see https://jsfiddle.net/7ox0hg9L/).
First, the on/off overlay toggle works fine, but if I pan/zoom the image the overlay reappears, even though toggle-off deletes the element from the DOM using parentNode.removeChild().
Second, I can't seem to get the overlay tooltips to work consistently on the first page, and they never appear on the following pages. The tooltip on the radiobutton label works fine on any page though, so I'm not sure why the tooltips on the overlays do not.
Any suggestion would be welcome. Please bear in mind that I am new to javascript. Thanks!
EDIT: iangilman's answer below and his edits on jsfiddle put me back on track, and helped me create the gallery I had in mind. I post here the full solution for those who may need similar features. Thanks Ian!

Looks like you're off to a good start!
You're correctly adding the overlays with addOverlay, so you need to remove them with removeOverlay:
runtimeViewer.removeOverlay(element);
For the tooltips, unfortunately OpenSeadragon's event handling can interfere with jQuery, so you'll have to use the OpenSeadragon MouseTracker:
function bindTooltip(elt) {
new OpenSeadragon.MouseTracker({
element: elt,
enterHandler: function(event) {
// Show tooltip
},
exitHandler: function(event) {
// Hide tooltip
}
}).setTracking(true);
}

I implemented a map with markers pointing to airports, and when I click on a marker the name of the airport appears in a field. (All data included in a GEOJson external file). I just have a last problem that I can't resolve :
I can only select one marker at a time, and i want to be able to select multiples Markers, and make all the name appears in the field. I think that my problem are that I need to change the calling my features, but i don't know what to write instead. I already tried to change my function from "forEachFeatureAtPixel" to "forFeatureAtPixel" or things like that, but every time I break my map.
I'm a beginner in Javascript :/ Here is my JS code
var vectorLayer = new ol.layer.Vector({
source: new ol.source.Vector({
format: new ol.format.GeoJSON(),
url: '//localhost/osgis-ol3-leaflet-master/ol3/data.geojson'
}),
style: new ol.style.Style({
image: new ol.style.Circle({
radius: 10,
fill: new ol.style.Fill({
color: 'green'
})
})
})
});
var rasterLayer = new ol.layer.Tile({
source: new ol.source.TileJSON({
url: 'http://api.tiles.mapbox.com/v3/mapbox.geography-class.json',
crossOrigin: ''
})
});
var map = new ol.Map({
layers: [rasterLayer, vectorLayer],
target: document.getElementById('map'),
view: new ol.View({
center: [0, 0],
zoom: 3
})
});
var input = document.getElementById('id-airports');
var select_interaction = new ol.interaction.Select();
map.addInteraction(select_interaction);
select_interaction.on('select', function(evt) {
var features = select_interaction.getFeatures();
var value = '';
features.forEach(function(feature){
// change this to your own needs
value += feature.get('name') + ', ';
});
input.value = value;
});
map.on('pointermove', function(e) {
if (e.dragging) return;
var hit = map.hasFeatureAtPixel(map.getEventPixel(e.originalEvent));
map.getTarget().style.cursor = hit ? 'pointer' : '';
});
UPDATE:
(fiddle) — To select multiple use Shift + Click
You will remove that another approach:
map.on('click', function(evt) {
var feature = map.forEachFeatureAtPixel(
evt.pixel, function(ft, l) { return ft; });
if (feature) ...
});
And use ol.interaction.Select, see bellow.
There's a select interaction that you can add to your map with a lot of options, see ol.interaction.Select. You can set, for instance some conditions:
// only select with Mouse Hover
var select_interaction = new ol.interaction.Select({
condition: ol.events.condition.pointerMove
});
Another condition:
// only select with Alt key + Click
var select_interaction = new ol.interaction.Select({
condition: function(mapBrowserEvent) {
return ol.events.condition.click(mapBrowserEvent) &&
ol.events.condition.altKeyOnly(mapBrowserEvent);
}
});
In your case, putting all together would be something like:
var select_interaction = new ol.interaction.Select();
map.addInteraction(select_interaction);
// add a listener to know when features are selected
select_interaction.on('select', function(evt) {
var features = select_interaction.getFeatures();
features.forEach(function(feature){
// change this to your own needs
input.value += feature.get('name') + ', ';

function initialize() {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-33, 151),
mapTypeControl: true,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.DEFAULT,
mapTypeIds: [
google.maps.MapTypeId.ROADMAP,
google.maps.MapTypeId.TERRAIN
]
},
zoomControl: false,
zoomControlOptions: {
style: google.maps.ZoomControlStyle.SMALL
}
};
var map = new google.maps.Map(document.getElementById('mapviewer'),
mapOptions);
map.setOptions({draggable: false, zoomControl: false, scrollwheel: false, disableDoubleClickZoom: true});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<script type="text/javascript">
function performClick(elemId) {
var elem = document.getElementById(elemId);
if(elem && document.createEvent) {
var evt = document.createEvent("MouseEvents");
evt.initEvent("click", true, false);
elem.dispatchEvent(evt);
}
}
</script>
</div>

Draggable Icons on a Google Map V3 - Set to Draggable=True, but can not drag it

I have everything working on this Google map V3 on how I would like it except for one last thing. Right now, If you load up the map, the map is able to search for a place and drag an icon from outside the map into the Google map. However, once the icon is inside the map, I am not able to drag it. I've search endlessly on where I went wrong on my code.
Below are a few examples of many that I read on:
Link1,
Link2, Link3, Link4 (Link 4 is what i need but could not connect the code after further inspection)
I feel I am very close but I believe I am just not declaring the right variables or not connecting them right. Below is the code and here is a FIddle that can give you a picture of my problem. (Try dragging the icon once and then dragging it again inside the map)

end of code
If you guys can let me know that would be great! Also, i noticed that marker is declared twice. Is that one of the problems? I tried declaring something else but had no luck.
I also came accross this code but not sure if it is helpful in this situation
var overlay;
overlay = new google.maps.OverlayView();
overlay.draw = function() {};
overlay.setMap(map);
Possibly thinking it has to do something with this piece of code below?
function placeMarker(location, icon) {
var marker = new google.maps.Marker({
position: location,
map: map,
draggable:true,
icon: icon
});
}
But then again, couldn't figure what was wrong with, am I connecting the variables correctly?
Help would be greatly appreciated, I am very close to finishing what I want to accomplish on this map
Check to make sure you are not using svg images for the icon. They seem to work on FireFox and Chrome, but not IE
