angular 7 - 重新加载数据 table
angular 7 - reload data in data table
我正在使用 angular 7 和 angular-数据表。
我正在尝试定义一个 "rerender" 按钮以重新加载数据 like in this example.
我不明白我应该在渲染函数中放置什么:
我的API函数:
fn_getFavoriteTables() {
this._getFavoriteTablesApiCall = this.getFavoriteTablesService.getFavoriteTables(Number(localStorage.getItem('UserID')), Number(localStorage.getItem('BranchID'))).pipe(takeUntil(this.destroySubject$)).subscribe(x => {
this.getFavoriteTables = x;
this.dtTrigger.next();
});
};
重新渲染函数:
rerender(): void {
this.dtElement.dtInstance.then((dtInstance: DataTables.Api) => {
// Destroy the table first
dtInstance.destroy();
// Call the dtTrigger to rerender again
this.dtTrigger.next();
});
}
ngOnDestroy(): void {
console.log('ngDestroy');
// Do not forget to unsubscribe the event
this.dtTrigger.unsubscribe();
}
找到适合我的答案:
this is the source site
rerender(): void {
this.dtElement.dtInstance.then((dtInstance: DataTables.Api) => {
// Destroy the table first
//debugger;
var table = $('#favoriteTable').DataTable();
$('#tableDestroy').on('click', function () {
table.destroy();
});
dtInstance.destroy();
this.fn_getFavoriteTables();
});
}
也可以这样做:
import { DataTableDirective } from 'angular-datatables';
dtElement: DataTableDirective;
dtInstance: Promise<DataTables.Api>;
rerender(): void {
this.dtElement.dtInstance.then((dtInstance: DataTables.Api) => {
dtInstance.ajax.reload()
});
}
您可以使用 DataTable destroy() API 删除 table 并重新使用 dtTrigger 再次呈现 table。请查看下方 link.
