Google Maps Custom Tile Layer input onclick adds same layer as twice
0
I added gebco tiles on my google map with custom input control.
it looks like it works fine but i noticed that layer is added twice.
I created a sample fiddle showing that when you click the input it adds the gebco layer twice on console.
I also added a snippet if it is better. So I couldn't figure out why it adds the layer as twice.
Any ideas how to prevent it adding the gebco layer twice?

This will solve your issue:
$("div").on("click", "#otherlayers input[id='gebco']", function (e) {
e.stopPropagation()
setgebcolayer(this);
var layerArray = map.overlayMapTypes.getArray();
console.log(layerArray);
});
you just have to add e.stopPropagation()

As you are using input checkbox, listening to the change event is the better choice as follows. It works!!
$(document).on("change","input[id='gebco']",function(e){
setgebcolayer(this);
var layerArray = map.overlayMapTypes.getArray();
console.log(layerArray);
})
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 2,
maxZoom: 8,
minZoom: 1,
center: {
lat: 0,
lng: -0
},
disableDefaultUI: false,
zoomControl: true,
mapTypeControl: false,
streetViewControl: false,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
function CenterControl(controlDiv, map) {
// Bulut Custom Map Control
var controlUI = document.createElement('div');
controlUI.style.cursor = 'pointer';
controlUI.style.textAlign = 'center';
controlUI.title = 'Please Select a Weather Layer';
controlDiv.appendChild(controlUI);
var controlText = document.createElement('div');
controlText.innerHTML = '<table id="otherlayers"><tbody><tr><td><input type="checkbox" id="gebco" data-opacity="1"><label for="gebco">Wind Stream</label></td></tr></tbody></table>';
controlUI.appendChild(controlText);
$(document).on("change","input[id='gebco']",function(e){
setgebcolayer(this);
var layerArray = map.overlayMapTypes.getArray();
console.log(layerArray);
})
}
var gebcoLayer =
new google.maps.ImageMapType(
{
getTileUrl: function (coord, zoom) {
var tilesPerGlobe = 1 << zoom;
var x = coord.x % tilesPerGlobe;
if (x < 0) {
x = tilesPerGlobe + x;
}
var bbox2 = tileCoordsToBBox(map, coord, zoom, 256, 256);

JQuery is running the click event twice. The line below triggers twice on a click:
$("div").on("click", "#otherlayers input[id='gebco']", function (e) {

This will solve your issue:
$("div").on("click", "#otherlayers input[id='gebco']", function (e) {
e.stopPropagation()
setgebcolayer(this);
var layerArray = map.overlayMapTypes.getArray();
console.log(layerArray);
});
you just have to add e.stopPropagation()
