The use of the search box in the ArcGIS API for JavaScript __arcgis

We often need to use the search box to search for a certain data on the map, and then show it on the map. This time we need to use Esri.dijit.Search (). When setting the sources inside, you need to be aware that you must use the online Featurelayer. Such as:

Although sources can also be set with local settings (with Featurecollectionobject settings), it cannot be queried after this setting, which is clearly written in the official document. URL: Https://developers.arcgis.com/javascript/3/jsapi/featurelayer-amd.html#featurelayer2

So if the data is local, you need to upload it to Arcgisonline (http://www.arcgisonline.cn/), then publish the data, then refer to the online address and assign the value to Featurelayer.
