"Unindexing data in Angular: A step-by-step guide

Can someone help me figure out how to delete an item by index in Angular? I have a parameter and a remove button, but when I tried putting my parameter inside the remove button it didn't work. How can I fix this?

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){}
    })
   
  }

HTML

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

Answer №1

When it comes to JavaScript, the removeAt method is not available; however, a suitable alternative is to utilize splice.

this.uploadAttachments.splice(rowIndex,1);

Answer №2

My approach involves updating the array by creating a new array that filters out the specific item to be removed

this.updatedItems = this.uploadAttachments.filter((element, index) => index !== targetIndex);
