Vue Lookup - ArrayStore

Extend a JavaScript array's functionality by placing it into an ArrayStore. It provides an interface for loading and editing data, and allows you to handle data-related events.

jQuery
JavaScript
$(function() {
    $("#lookupContainer").dxLookup({
        dataSource: new DevExpress.data.ArrayStore({
            data: products,
            onLoaded: function() {
                // Event handling commands go here
            }
        }),
        valueExpr: 'price',
        displayExpr: 'name'
    });
});
Angular
HTML
TypeScript
<dx-lookup
    [dataSource]="lookupDataSource"
    valueExpr="price"
    displayExpr="name">
</dx-lookup>
import { DxLookupModule } from "devextreme-angular";
import ArrayStore from "devextreme/data/array_store";
// ...
export class AppComponent {
    products = [/* ... */ ];
    lookupDataSource = new ArrayStore({
        data: this.products,
        onLoaded: function () {
            // Event handling commands go here
        }
    });
}
@NgModule({
    imports: [
        // ...
        DxLookupModule
    ],
    // ...
})
Vue
<template>
    <DxLookup
        :data-source="dataSource"
        value-expr="price"
        display-expr="name"
    />
</template>

<script>
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import { DxLookup } from 'devextreme-vue/lookup';
import ArrayStore from "devextreme/data/array_store";

const products = [/* ... */ ];

export default {
    components: {
        DxLookup
    },
    data() {
        return {
            dataSource: new ArrayStore({
                data: products,
                onLoaded: function () {
                    // Event handling commands go here
                }
            })
        };
    }
}
</script>
React
import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import { Lookup } from 'devextreme-react/lookup';
import ArrayStore from "devextreme/data/array_store";

const products = [/* ... */ ];

class App extends React.Component {
    constructor(props) {
        super(props);

        this.dataSource = new ArrayStore({
            data: products,
            onLoaded: function () {
                // Event handling commands go here
            }
        });
    }

    render() {
        return (
            <Lookup
                dataSource={this.dataSource}
                valueExpr="price"
                displayExpr="name"
            />
        );
    }
}

export default App;

Data kept in the ArrayStore can be processed in a DataSource. For example, the DataSource can sort data.

jQuery
JavaScript
const products = [
    { name: "HD Video Player", price: 100 },
    { name: "SuperHD Video Player", price: 420 },
    { name: "SuperPlasma 50", price: 1500 },
    { name: "SuperLED 50", price: 200 }
];

$(function() {
    $("#lookupContainer").dxLookup({
        dataSource: new DevExpress.data.DataSource({
            store: products,
            sort: { getter: "name", desc: true }
        }),
        valueExpr: 'price',
        displayExpr: 'name'
    });
});
Angular
HTML
TypeScript
<dx-lookup
    [dataSource]="lookupDataSource"
    valueExpr="price"
    displayExpr="name">
</dx-lookup>
import { DxLookupModule } from "devextreme-angular";
import DataSource from "devextreme/data/data_source";
// ...
export class AppComponent {
    products = [/* ... */ ];
    lookupDataSource = new DataSource({
        store: this.products,
        sort: { getter: "name", desc: true }
    });
}
@NgModule({
    imports: [
        // ...
        DxLookupModule
    ],
    // ...
})
Vue
<template>
    <DxLookup
        :data-source="dataSource"
        value-expr="price"
        display-expr="name"
    />
</template>

<script>

import { DxLookup } from 'devextreme-vue/lookup';
import DataSource from "devextreme/data/data_source";

const products = [/* ... */ ];

export default {
    components: {
        DxLookup
    },
    data() {
        return {
            dataSource: new DataSource({
                store: products,
                sort: { getter: "name", desc: true }
            })
        };
    }
}
</script>
React
import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import { Lookup } from 'devextreme-react/lookup';
import DataSource from "devextreme/data/data_source";

const products = [/* ... */ ];

class App extends React.Component {
    constructor(props) {
        super(props);

        this.dataSource = new DataSource({
            store: products,
            sort: { getter: "name", desc: true }
        });
    }

    render() {
        return (
            <Lookup
                dataSource={this.dataSource}
                valueExpr="price"
                displayExpr="name"
            />
        );
    }
}

export default App;
NOTE
Even if you have passed a JavaScript array to the dataSource property, the Lookup automatically places it into an ArrayStore wrapped into the DataSource you can get with the getDataSource() method.
