DevExtreme jQuery/JS - Overview
The SelectBox widget is an editor that allows an end user to select an item from a drop-down list.
The following code adds the SelectBox 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 SelectBox is empty.
jQuery
HTML
JavaScript
<div id="selectBoxContainer"></div>
$(function() { $("#selectBoxContainer").dxSelectBox({ dataSource: [ "HD Video Player", "SuperHD Video Player", "SuperPlasma 50", // ... ], placeholder: "Select a product..." }); });
Angular
HTML
TypeScript
<dx-select-box [dataSource]="products" placeholder="Select a product..."> </dx-select-box>
import { DxSelectBoxModule } from "devextreme-angular"; // ... export class AppComponent { products = [ "HD Video Player", "SuperHD Video Player", "SuperPlasma 50", // ... ]; } @NgModule({ imports: [ // ... DxSelectBoxModule ], // ... })
If your data is an array of objects, specify:
- valueExpr
The data field whose value will be written into the value option. - displayExpr
The data field whose value will be displayed in the drop-down list and in the input field of the widget.
