ngFor index reset to 0 when used with ngx-pagination

<tr *ngFor="let data of rawDataListDup | filter:searchText | paginate: { itemsPerPage: 100,currentPage: q }; let idx = index">
<td>
  <select (change)="AssigneeChange(data,$event.target.value,idx)">
   <option [value]="data1.id" *ngFor="let data1 of groupList">{{ data1.name }}</option>
  </select>
</td>
</tr>

Consider rawDataListDup items as 300. In above code idx value reset to 0, when ever I go to next page in table.

AssigneeChange(data,id,idx){
  console.log(data,id,idx)
}

Consider the current index of rawDataListDup as 100. In the console i get idx = 0 instead of idx = 100 when function AssigneeChange is called. This happens when i am in page = 2 of table. In every page there will be 100 items.

How to solve this problem?

Solution

  • Please refer this for solution..

    We can get absolute index using below code since paginate doesn't recognise it.

    AssigneeChange(data,id,idx){ 
idx = 100 * (this.q - 1) + idx;
console.log(data,id,idx)
}
