Retrieve the mfData value from the TypeScript file in order to perform operations on it within the Angular 2 framework

I have a snippet of code that iterates through data from stacklist_table, which is a JSON array, and displays it in a table format. The stacklist_table contains a full list of objects, but I only need a subset of these objects so I have applied some filters using pipes. The final result is stored in #stacklist, which is then used to display columns and rows.

<table class="table" [mfData]="stacklist_table | selectedcolumn | search : searchQuery | filter: addFilter : selected" #stacklist="mfDataTable">
              <thead>
                <tr>
                  <th *ngFor="let colValues of stacklist.data | column: '' : ''">
                    <mfDefaultSorter by="{{colValues}}">{{colValues|translate}}</mfDefaultSorter>
                  </th>
                </tr>
              </thead>
              <tbody>
                <tr draggable *ngFor="let stack of stacklist.data" [dragOverClass]="'drag-over-border'" [dragData]="stack" [class.active]="checkIfStackElementIsSelected(stack)" (click)="setStacklistRow(stack)">
                  <td *ngFor="let rowValues of stack | row">{{ rowValues }}</td>
                </tr>
              </tbody>
            </table>

Is it possible to access the value stored in #stacklist in my backend TypeScript file? I require the final version of stacklist after all the filters have been applied in the TypeScript file. How can I achieve this?

Answer №1

To access the data post pipes application in your component.ts, you have the option to directly apply pipes within your component.

import { CustomPipe } from './custom.pipe';

export class MyComponent {
   constructor(private customPipe: CustomPipe){
     this.transformedData = this.customPipe.transform(someData); // similar to using "someData | CustomPipe" in the template
   }       
}

Now, you can manipulate the data with applied pipes (this.transformedData) and then utilize it in both the component and template. This approach allows for a single use of pipes (in the component) with results accessible on both ends seamlessly.
