如何删除角度索引

Question

如何删除每个索引，我有一个参数和删除按钮，我试图将我的参数放在我的删除按钮中，但它不起作用如何解决这个问题？

deleteRowFiles(rowIndex: number){
  this.getListFileName();
  if(this.uploadAttachments.length > 1){
    Swal.fire({
      title: 'Are you sure?',
      text: 'You will not be able to recover this data!',
      icon: 'error',
      showCancelButton: true,
      confirmButtonText: 'Confirm',
      cancelButtonText: 'Cancel'
    }).then((result) => {
      if(result.value){
       
        this.uploadAttachments.removeAt(rowIndex);
        
        this.microSvc.deleteFile(this.iData.transactionType,this.uploadedFiles).pipe(
         return this.refreshPage();
        }) 
       
      }else if (result.dismiss === Swal.DismissReason.cancel){}
    })
   
  }

超文本标记语言

<td (click)="deleteRowFiles(i)">
<i class="fa fa-trash fa-2x"></i>
</td>

  

Answer 1

我总是用一个新的数组替换数组引用，其中要删除的项已经被过滤掉了

this.uploadAttachments = this.uploadAttachments.filter((_, i) => i !== rowIndex);

Answer 2

javascript中没有removeAt，你可以使用splice来代替

 this.uploadAttachments.splice(rowIndex,1);
