Search widget not suggesting/ not displaying any result from feature layer

reneeshtk — Thu, 11 Jul 2019 09:40:51 GMT

I have displayed a map using webmap and now trying to implement the search.. but it is not doing search in the feature layer.. What is wrong I am doing?

const testLayer = map.allLayers.find(function(layer) {

return layer.title === "mytestlayer";

});

var searchWidget = new Search({

view: view,

allPlaceholder: "Search",

sources: [

{

layer: testLayer,

searchFields: ["myfield"],

suggestionTemplate: "{myfield}",

exactMatch: false,

outFields: ["*"],

name: "testing",

placeholder: "example: test"

}

]

});

view.ui.add(searchWidget, {

position: "top-right"

});

Hi reneesh tk‌,

Please find below the code for a working example of a Search Widget searching a Feature Layer.

It searches a Feature Layer with Dutch municipalities ("Gemeenten"): https://services.arcgis.com/nSZVuSZjHpEZZbRo/arcgis/rest/services/Bestuurlijke_Grenzen_Gemeenten_2019/FeatureServer/0 and if you type Amster it will come up with the suggestion Amsterdam 🙂

You can see the page in action here: Aan de slag met ArcGIS JavaScript - Feature zoeken

I hope this example will help you to get your code up and running.

Best regards,

Egge-Jan

We also have a hosted sample that shows how to work with the Search widget and setting the source to a FeatureLayer:
