多项选择默认值

Question

我正在使用角度7，我有一个要更新住宅的表格，所以我想用住宅的数据填充它。我在多重选择方面遇到问题，我有

<div class="form-group form-default">
   <ng-select [(ngModel)]="residential.sections" name="sections" [ngClass]="'ng-select'" [options]="options" [multiple]="true"></ng-select>
</div>

residential: Residential;
options = [
        {value: '1', label: 'Clusters'},
        {value: '2', label: 'Códigos'},
        {value: '3', label: 'Directorios'},
        {value: '4', label: 'Documentos'},
        {value: '5', label: 'Propiedades'},
        {value: '6', label: 'Reportes'},
        {value: '7', label: 'Residenciales'},
        {value: '8', label: 'SOS'},
        {value: '9', label: 'Usuarios'}
];

resident.sections是一个像[1, 2]这样的数组。如何设置默认值？我试着将Residential.sections用作简单的数组[1,2]，并且类似于选项数组

[{value: '1', label: 'Clusters'},{value: '2', label: 'Códigos'}]

Answer 1

只需将默认值设置为Residential.sections
