在 Angular 中单击编辑时内联编辑表格行

Question

我有一个表，其中数据正在填充。每行都有一个编辑链接。我只想在单击编辑链接时编辑特定行。现在它的'显示所有行的编辑选项。

我还想在单击编辑时在输入框中显示文本。

这是我的代码。

<tr *ngFor="let row of backendData.report"  class="hover-highlight">

          <td class="benchmark_name">
             {{row.name}}
          </td>
          <td>
            {{row.value}}
          </td>
          <td>
            {{row.description}}
          </td>
          <td>
              <button *ngIf="enableEdit" (click)="enableEdit=false" class="btn page-secondary-action-btn" ng-click="cancel()">Cancel</button>
              <button *ngIf="enableEdit" id="saveBtn" class="btn page-primary-action-btn" (click)="saveSegment()" type="submit">Save</button>
              <a class="table-row-action edit-action" *ngIf="!enableEdit" (click)="enableEdit = true">
          <i class="fa fa-pencil" uib-tooltip="Edit" tooltip-trigger="mouseenter" tooltip-append-to-body="true" tooltip-placement="left"></i>
        </a>
          </td>
          <td>

          </td>
        </tr>

我当前的输出看起来像这样

这是解决方案

html

<tr *ngFor="let row of backendData; index as i;"  class="hover-highlight">

          <td class="benchmark_name">
             {{row.name}}
          </td>
          <td>
            {{row.value}}
          </td>
          <td>
            {{row.description}}
          </td>
          <td>
              <button *ngIf="enableEdit && enableEditIndex == i" (click)="enableEdit=false" class="btn page-secondary-action-btn" ng-click="cancel()">Cancel</button>
              <button *ngIf="enableEdit && enableEditIndex == i" id="saveBtn" class="btn page-primary-action-btn" (click)="saveSegment()" type="submit">Save</button>
              <a href="#" class="table-row-action edit-action" *ngIf="!enableEdit" (click)="enableEditMethod($event, i)">
                edit
        </a>
          </td>
          <td>

          </td>
        </tr>

.ts 文件

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular';
  enableEdit = false;
  enableEditIndex = null;
  backendData = [{
    "name": 'Target',
    "value": '100',
    "description": 'abc'
  },
  {
    "name": 'Size',
    "value": '20',
    "description": 'def'
  },
  {
    "name": 'Industry',
    "value": '40',
    "description": 'ghi'
  }]

  enableEditMethod(e, i) {
    this.enableEdit = true;
    this.enableEditIndex = i;
    console.log(i, e);
  }
}
