DevExtreme jQuery/JS - Overview
The Autocomplete widget is a textbox that provides suggestions while a user types into it.
The following code adds the Autocomplete to your page. The simplest configuration of the widget requires only a dataSource to be specified. In addition, you can specify the placeholder to be displayed when the Autocomplete is empty.
jQuery
<div id="autocompleteContainer"></div>
var autocompleteData = [ "Afghanistan", "Albania", // ... ]; $(function() { $("#autocompleteContainer").dxAutocomplete({ dataSource: autocompleteData, placeholder: 'Type country name...' }); });
Angular
<dx-autocomplete [dataSource]="autocompleteData" placeholder="Type country name..."> </dx-autocomplete>
import { DxAutocompleteModule } from 'devextreme-angular' // ... export class AppComponent { autocompleteData = [ "Afghanistan", "Albania", // ... ] } @NgModule({ imports: [ // ... DxAutocompleteModule ], // ... })
If your data is an array of objects, use the valueExpr option to specify the field providing suggestions.
jQuery
var autocompleteData = [ { country: "Afghanistan", capital: "Kabul" }, { country: "Albania", capital: "Tirana" }, // ... ]; $(function() { $("#autocompleteContainer").dxAutocomplete({ dataSource: autocompleteData, placeholder: 'Type country name...', valueExpr: 'country' }); });
Angular
<dx-autocomplete [dataSource]="autocompleteData" placeholder="Type country name..." valueExpr="country"> </dx-autocomplete>
import { DxAutocompleteModule } from 'devextreme-angular' // ... export class AppComponent { autocompleteData = [ { country: "Afghanistan", capital: "Kabul" }, { country: "Albania", capital: "Tirana" }, // ... ] } @NgModule({ imports: [ // ... DxAutocompleteModule ], // ... })
Usually, the data field that provides suggestions is the same data field that is searched for the typed text. If in your case, it is two different fields: assign the field providing suggestions to the valueExpr option and the field to be searched - to the searchExpr option. Note that searchExpr also accepts arrays in case you need several fields to search in.
jQuery
var autocompleteData = [ { country: "Afghanistan", capital: "Kabul" }, { country: "Albania", capital: "Tirana" }, // ... ]; $(function() { $("#autocompleteContainer").dxAutocomplete({ dataSource: autocompleteData, placeholder: 'Type capital name', valueExpr: 'country', searchExpr: 'capital' }); });
Angular
<dx-autocomplete [dataSource]="autocompleteData" placeholder="Type country name..." valueExpr="country" searchExpr="capital"> </dx-autocomplete>
import { DxAutocompleteModule } from 'devextreme-angular' // ... export class AppComponent { autocompleteData = [ { country: "Afghanistan", capital: "Kabul" }, { country: "Albania", capital: "Tirana" }, // ... ] } @NgModule({ imports: [ // ... DxAutocompleteModule ], // ... })
