我使用 angular 和SweetAlert2。在我想调用服务或确认后的任何函数或变量之前,我的 sweetalert2 工作得非常好。
我的组件:
import swal from 'sweetalert2';
@Component({
selector: 'app-filter',
templateUrl: './filter.component.html',
})
export class FilterComponent implements OnInit {
private swal: any;
constructor(private asyncService: AsyncService) {
}
ngOnInit() {
this.getCurrentData(1);
}
getCurrentData(id: number) {
this.asyncService.getCurrentFilterData(id)
.subscribe(
response => {
this.filter = response.json();
},
error => console.log('error : ' + error)
);
}
saveFilter() {
swal({
title: 'Are you sure?',
text: 'You wish to save filter changes!',
type: 'question',
showCancelButton: true,
confirmButtonText: 'Save',
cancelButtonText: 'Cancel'
}).then(function() {
this.asyncService.filterUpdate(this.filter) // can't access to this. (this.filter or this.asyncService)
.subscribe(
response => {
console.log('success');
},
error => console.log('error : ' + error)
);
});
}
有什么解决方案我怎样才能访问这个?
