  map.on("click", myClickHandler);

  function myClickHandler(evt) {

  }

如果您只想获得x＆amp; y坐标来自地图，答案由艾登提供。

如果您需要从地址信息中获取位置。您需要使用GeocodeServer服务来获取位置。您可以创建和托管自己的服务，也可以使用ESRI托管的服务。

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){
        ....
    });
});
