The cell that is currently been clicked should be the only cell opened and focus, and when I click other cell the previous one should close, right now I can open and click multiple sunsetDate cells at a time which is wrong.

How do we handle this in angular?

#html code

<td (click)="editStatus(data, 'sunsetDate' , i)"
                [ngClass]="indexEditing==i && selectedCell === 'sunsetDate' ? 'editing-cell' : ''"
                [ngClass]="!data.isRequired ? 'blank-cell' : ''" >
                <mat-form-field appearance="fill" *ngIf="indexEditing==i && selectedCell === 'sunsetDate'; else viewSunsetDate">
                    <mat-label>Choose a date</mat-label>
                    <input (blur)="blur()" [(ngModel)]="data.sunsetDate" (keyup.enter)="dateChange(data,'parent','sunsetDate')"
                        (keydown.tab)="dateChange(data,'parent','sunsetDate')" matInput (dateChange)="dateChange(data,'parent','sunsetDate')"
                        [matDatepicker]="picker" #inputField>

#ts code

@ViewChild('editDatePickerInputCell') editDatePickerInputCell:any;

     editDateTest(value: EntitlementTransactionTemplateDto, columnName: string) {
        value.editing = false
        value.editing = !value.editing
        this.selectedCell = columnName
    
        console.log('columnName' , columnName)
        console.log('Value' , value)
    
    
        if (value.editing) {
          setTimeout(() => {
            this.focusOnEditCell();
          }, 0)
        }
      }

      focusOnEditCell() {
    setTimeout(()=>{
      if(this.editDatePickerInputCell)
        this.editDatePickerInputCell.nativeElement.focus();
    },500); 
  }

#sample object being passsed when cell is clicked

{
    "id": 99,
    "transactionId": 13517,
    "name": "",
    "isHeaderCategory": false,
    "isRequired": true,
    "order": 3,
    "editing": true
}

CodePudding user response：

Instead use "data.editing" use a variable

indexEditing:number=-1;

So, you use:

  <!--you check agains indexEditing-->
  <mat-form-field *ngIf="indexEditing==index && 
               selectedCell === 'sunsetDate'; else viewSunsetDate">
      ...
  </mat-form-field>

In your function

editDateTest(value:EntitlementTransactionTemplateDto,index:number, columnName: string){
   this.indexEditing=index;
   ...
}

When you end editing, simply

dateChange(...){
  this.indexEditing=-1;
  ...
}

(*)If you has a *ngFor you simplly use

  <ng-container *ngFor="let data of yourList;let index=index">
  </ng-container>

If you're using mat-table, see that you use

<td mat-cell *matCellDef="let element; let index = index;">
  ...
</td>
