How to use view.goTo?

ShakilChoudhury — Wed, 07 Nov 2018 09:37:22 GMT

I have an x, y, spatialReference and zoom value that I need the map to go to. My map uses a custom basemap (same as the given spatial reference) and the view uses an extent value like so:

var view = new MapView({
container: "viewDiv",
map: map,
extent:new Extent ({"xmin": 554418, "ymin": 166279, "xmax": 584505, "ymax": 144457, "spatialReference":{"wkid": 27700}})
});

I can't get view.goTo to work no matter what I do.

Shakil,

Can you provide a sample?

var ex = new Extent({
center:{
x:564460.8649987298,
y:139625.260181187
}
});

view.goTo(ex);

Managed to get it working:

var geo = view.center;
geo.x = x;
geo.y = y;

view.goTo({
geometry:geo,
zoom:zoom
});

Worked for me as well. I have run into this a couple of times now. I think the documentation or api needs to be fixed. Documentation reads like the original should of worked and then {target: someGeometry} should work. Maybe I'm reading it wrong but I don't see any mention of using the geometry attribute for target. Am I reading this wrong Esri?

Is zoom required if you're requesting the map to be at full extent?

I'm not able to move to full extent. If I add zoom, the map just zooms.

var featureLayer = map.layers.getItemAt(1);

view.goTo({

target: featureLayer.fullExtent,

zoom: 11

}, ZoomOptions);

Using it like this does nothing

view.goTo(featureLayer.fullExtent);

Gregory,

According to the API docs view.goTo(featureLayer.fullExtent); should work.

my working code:

if you want to zoom to feature layer extend, use below function

function zoomToLayerExtent(layer)

if you want to zoom to lat, long, use below function

function zoomToLatLong(__lat, __long, __zoom){

var _url = "https://maps.lacity.org/arcgis/rest/services/Mapping/NavigateLA/MapServer/1"

var featureLayer = new FeatureLayer({

url: _url

});

map.add(featureLayer);

featureLayer.when(function() {

zoomToLayerExtent(featureLayer);

zoomToRealLocation(featureLayer)

});

function zoomToLayerExtent(layer) {

return layer.queryExtent().then(function(response) {

view.goTo(response.extent);

});

}

function zoomToLatLong(__lat, __long, __zoom){

// bug fix https://community.esri.com/thread/224073-how-to-use-viewgoto

// https://developers.arcgis.com/javascript/latest/api-reference/esri-views-MapView.html#goTo

var esri_point = new Point({

latitude: __lat,

longitude: __long

});

var esri_goto_option = {

animate: true,

duration: 200,

};

view.goTo({

target: esri_point,

zoom: __zoom

}, esri_goto_option)

.catch(function(error) {

if (error.name != "AbortError") {

console.error('zoom to real location, view goto error', error);

}

});

}
