如何使用ArcGIS JavaScript获得LAT长的地址

Question

嗨，我如何使用arcgis javascript获得纬度和经度？

Answer 1

3.x API看起来像

require(["esri/map"], function(Map) {
  var map = new Map("mapDiv"),
  map.on("click", myClickHandler);
  function myClickHandler(evt) {
    console.log(evt)
  }
});

2.x API看起来像这样：

dojo.connect(map, "onClick", mapClick);
function mapClick(evt){
     console.log(evt.mapPoint)
}

Answer 2

如果您只想获得x＆amp;y坐标来自地图，Aiden Works提供的答案。

如果您需要从地址信息获得位置。您需要使用地理编码器服务来获取位置。您可以创建和托管自己的服务或使用ESRI托管的服务之一。

http://sampleserver1.arcgisonline.com/arcgis/rest/services/locators/

require(["esri/tasks/locator", ... 
], function(Locator, ... ) {
    var locator = new Locator("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Locators/ESRI_Geocode_USA/GeocodeServer");
    var address = {"Single Line Input": "100 main street"};
    var params = {address: address, searchExtent: map.extent};              
    locator.outSpatialReference= map.spatialReference;
    locator.addressToLocations(params).then(function(addressCandidates){
        ....
    });
});
