我使用* ngFor来迭代数据表中的对象数组和序列号。我使用let index of i
,然后将其打印到表格,但我面临的问题是,在第9个序列号之后。我得到了10但是在1序列号后没有。像1,10,11,2,3。任何人都可以帮我这个吗?这是我的打字稿代码和HTML代码。
// GETTING BONUS DATA
getAllJobposts() {
this.apiService.hrService.getAllJobPost().subscribe((res: any) => {
this.jobPostsData = res.data;
console.log(this.jobPostsData);
// this.DataTablesFunctionCallAfterDataInit()
});
}
<tr class="MousePointer" (click)="EditRecord(post.id, target)" *ngFor="let
post of jobPostsData | reverse; let i = index">
<td>{{ i+1 }}</td>
<td>
<span style="display: inline">
<a class=" btn btn-link btn-sm " title="Delete" [id]="post.id" (click)="$event.stopPropagation();modal.ShowModal(post.id)">
<i [ngStyle]="{color: 'blue'}" class="fa fa-trash-o ">
</i>
</a>
<a class="btn btn-link btn-sm btn-round" title="Edit" (click)="$event.stopPropagation();EditRecord(post.id,target)">
<i [ngStyle]="{color: 'blue'}" class="fa fa-pencil-square-o "></i>
</a>
</span>
</td>
<td>{{ post.jobTitle }}</td>
<td>{{ getDepartmentName(post.departmentId) }}</td>
<td>{{ getDesignationName(post.designationId) }}</td>
<td>{{ post.totalPosition }}</td>
<td>{{ post.minExperience }}</td>
<td>{{ getCityName(post.cityId) }}</td>
<td>
<span [class]="post.active == 1? 'status success':'status danger'" style="width:60px !important; text-align: center;">
{{post.active == 1? "Active":"In-Active" }}
</span>
</td>
</tr>
似乎你需要通过以下方式重写你的reverse
管道:
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({ name: 'reverse' })
export class ReversePipe implements PipeTransform {
transform(value) {
return value.sort((a, b) => {
return (b.id - a.id);
});
}
}
在sort函数中,您需要指定用于排序的对象:return (b.id - a.id)
。
或者如果id是字符串,则使用parseInt(b.id) - parseInt(a.id)
(否则它将输出与截图中相同的结果,即按字母顺序排列)
此外,您可以通过parameters of pipe传递对象字段进行排序
