選項我基於PrimeNG的DataTable爲我的應用程序創建一個可重用的表組件。Primeng DataTable下拉菜單不能使用列
我的組件具有以下的html代碼:
<p-dataTable [value]="cars" [rows]="5" [paginator]="true" [globalFilter]="gb" [(selection)]="selectedValue" (onRowSelect)="onRowSelect($event)" #dt>
<p-column *ngIf="hasSelectCheckbox" [style]="{'width':'38px'}" selectionMode="single"></p-column>
<p-column *ngIf="hasExpander" expander="true" styleClass="col-icon"></p-column>
<p-column *ngFor="let col of cols" [field]="col.field" [header]="col.header" [sortable]="col.sortable" [filter]="col.hasFilter" filterPlaceholder="{{col.filterPlaceholder||'Search'}}" filterMatchMode="{{col.filterMatchMode}}">
<ng-template *ngIf="col.hasDropdownFilter" pTemplate="header" let-col>
<p-dropdown [options]="brands" appendTo="body" [style]="{'width':'100%'}" (onChange)="myfilter($event.value,col.field,col.filterMatchMode); dt.filter($event.value,col.field,col.filterMatchMode); " styleClass="ui-column-filter"></p-dropdown>
</ng-template>
</p-column>
</p-dataTable>
而在.TS我有
cars: Car[] = [];
selectedValue: Car;
hasSelectCheckbox = true;
hasExpander = false;
brands: SelectItem[] = [];
cols: any[] = [];
ngOnInit() {
this.brands = [
{label: 'Select a Brand', value: null},
{label: 'VW1', value: 'VW1'},
{label: 'VW2', value: 'VW2'},
{label: 'VW3', value: 'VW3'},
{label: 'VW4', value: 'VW4'}
]
this.cols = [
// tslint:disable-next-line:max-line-length
{field: 'vin', header: 'Vin', sortable: true, hasFilter: true, filterPlaceholder: null, filterMatchMode: 'contains' , hasDropdownFilter: null, hasMultiSelectFilter: null, dropdownItems: null},
{field: 'year', header: 'Year', sortable: true, hasFilter: false, filterPlaceholder: null, filterMatchMode: 'contains' , hasDropdownFilter: null, hasMultiSelectFilter: null, dropdownItems: null},
// tslint:disable-next-line:max-line-length
{field: 'brand', header: 'Brand', sortable: false, hasFilter: false, filterPlaceholder: null, filterMatchMode: 'equals' , hasMultiSelectFilter: null, hasDropdownFilter: true, dropdownItems: this.brands },
{field: 'color', header: 'Color', sortable: true, hasFilter: false, filterPlaceholder: null, filterMatchMode: 'contains' , hasDropdownFilter: null, hasMultiSelectFilter: null, dropdownItems: null}
];
/* this.carService.getCarsSmall().then(cars => this.cars = cars); */
this.cars.push(
{vin: 'Somet0', year: 1998, brand: 'VW1', color: 'White1'},
/* fill some data*/
);
}
而這一切都worki NG。
因爲我想要一個可重用的組件,我想使下拉項目依賴於列項目。但是,如果我使用「col.dropdownItems」而不是「品牌」,則下拉列表不會收到這些項目。
有沒有解決方案?
點擊所有標籤,閱讀他們的描述。你全部使用它們嗎? – Kukeltje
這取決於我將有哪種類型的collum –
