Hsu,

   Your code:

var pt = new Point(x, y, new SpatialReference({ wkid: 4326 }));

was the way it was done in 3.x API. In the 4.x API you need to provide an object in the Point constructor that specifies the objects property names:

var pt = new Point({x: x, y: y, spatialReference: new SpatialReference({ wkid: 4326 })});

Here is an updated sample:

Thanks

but I want "search[ lon, lat]  to address(not click map to address)"

this my code:

var locator = new Locator("http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer");
var x = parseFloat(lon);
var y = parseFloat(lat);
var pt = new Point(x, y, new SpatialReference({ wkid: 4326 }));

-------------------------------------------------------

got error this :

Uncaught TypeError: c.indexOf is not a function

Thank your help

I have two questions.

1.

this my code.

var locator = new Locator("https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer");
var x = parseFloat(-118.51732330322035);
var y = parseFloat(34.250812723611325);
var pt = new Point({
x: x,
y: y,
spatialReference: new SpatialReference({ wkid: 4326 })
});
locator.locationToAddress(pt, 100).then(function(evt){
if (evt.address) {
var address = {Address: evt.address};

}
});

---------------------------------------------------------

get error this:

Uncaught TypeError: a.clone(...).normalize is not a function
at Object.b.locationToAddress (Locator.js:8)
at Location.js?20161027:388
at K (dojo.js:18)
at dojo.js:19
at E (dojo.js:19)
at da (dojo.js:19)
at e (dojo.js:21)
at HTMLScriptElement.<anonymous> (dojo.js:23)

What have I ignored?

2.The sample you provided

var address = {Address: evt.address};
I want to get "Match_addr" , but I can't
Why?
{"address":{"Match_addr":"17545 Lassen St, Northridge, California, 91325","LongLabel":"17545 Lassen St, Northridge, CA, 91325, USA","ShortLabel":"17545 Lassen St","Addr_type":"PointAddress","Type":"","PlaceName":"","AddNum":"17545","Address":"17545 Lassen St","Block":"","Sector":"","Neighborhood":"Northridge","District":"","City":"Northridge","MetroArea":"Los Angeles Metro Area","Subregion":"Los Angeles County","Region":"California","Territory":"","Postal":"91325","PostalExt":"","CountryCode":"USA"},"location":{"x":-118.51724250000001,"y":34.250362478792603,"spatialReference":{"wkid":4326,"latestWkid":4326}}}

Hsu,

Don't forget to mark this question as answered by clicking on the "Mark Correct" link on the reply that answered your question.

  1. var x = parseFloat(-118.51732330322035); 
    var y = parseFloat(34.250812723611325); 

You are telling the parseFloat function to parse a number (which make no sense). The parseFloat is for making a sting a number.

This would be correct:

var x = parseFloat('-118.51732330322035'); 
var y = parseFloat('34.250812723611325'); 

  2. Because Match_addr is not part of the evt object it is part of the evt.attributes object:

var address = {Address: evt.attributes.Match_addr};

function(Map, MapView, Search,
Point,
SpatialReference, Locator

var locator = new Locator("https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer");

var x = parseFloat('-118.51732330322035');
var y = parseFloat('34.250812723611325');
var pt = new Point({
x: x,
y: y,

});

locator.locationToAddress(pt, 100).then(function(evt){

Thank your help.

My other two questions.
1. There is something wrong with the address returned by location. If I want to provide information and ask you to modify it.
What should I do?
Because some locations return the store name, it is not the address of the return details.
2.google api "timezone", is there a way to convert?

Hsu,

  1. I have never run into that situation. You have looked through all the attributes in the returned event and are sure the infomation you need is not returned right?
  2. "google api" ???....
