javascript - 如何从 Angular 的 api 在单选组中使用 ngModel

Question

这是代码。

list.component.html

<form nz-form [formGroup]="taskFormGroup" (submit)="saveFormData()">
    <div nz-row *ngFor="let remark of checklist">
              <div nz-col nzXXl="12" *ngFor="let task of remark.tasks" style="padding: .5rem;">
                <div nz-row nzGutter="6" nzType="flex" nzAlign="middle" style="border-left: 5px solid rgba(167, 0, 51, 0.5);">
                  <div nz-col nzSpan="8">
                    <label [textContent]="task.name"></label>
                  </div>
                  <div nz-col nzSpan="8">
                    <nz-form-item>
                      <nz-form-control>
                        <nz-radio-group formControlName="radiostatus" [(ngModel)]="radio" (ngModelChange)="onChangeStatus($event)">
                          <label nz-radio nzValue="passed">Passed</label>
                          <label nz-radio nzValue="failed">Failed</label>
                        </nz-radio-group>
                      </nz-form-control>
                    </nz-form-item>
                  </div>
                </div>
              </div>
            </div>
  </form>

list.component.ts

checklist = [
    {
      "id": "txv3vvBr8KYB",
      "assetType": {
        "id": "1fKBO4w0XHg7H",
        "code": "PRD",
        "name": "Printing1"
      },
      "tasks": [
        {
          "id": "1fKBO4w0XHg7H",
          "name": "Task 1",
          "description": "Check oil spill"
        },
        {
          "id": "ESOSA6aCrOER",
          "name": "Sample1",
          "description": "Desc1"
        }
      ]
    },
    {
      "id": "EwQciw9whx6B",
      "tasks": [
        {
          "id": "1nU7uASqfvLPD",
          "name": "TASK8888",
          "description": "DESC8888"
        },
        {
          "id": "EwQciw9whx6B",
          "name": "TASK9999",
          "description": "DESC9999"
        }
      ]
    }
  ];

当选择通过或失败时，当它选择第一个项目时，它不应该影响第二个项目。例如，在第一个项目上，它选择第二个项目中传递的内容，而不应该选择第二个项目中传递的内容。

就我而言，当我选择第一个项目上传递的内容时，它会影响它也选择传递的第二个项目。

在您的代码中，您对所有表单控件都有相同的 ngModel 绑定(bind) mame。尝试分配唯一的名称

组件.html

<div nz-row *ngFor="let remark of checklist; let  i = index">
      <div nz-col nzXXl="12" *ngFor="let task of remark.tasks" style="padding: .5rem;">
        <div nz-row nzGutter="6" nzType="flex" nzAlign="middle" style="border-left: 5px solid rgba(167, 0, 51, 0.5);">
          <div nz-col nzSpan="8">
            <label [textContent]="task.name"></label>
          </div>
          <div nz-col nzSpan="8">
            <nz-form-item>
              <nz-form-control>
                <nz-radio-group [(ngModel)]="task.id" (ngModelChange)="onChangeStatus($event)">
                  <label nz-radio nzValue="passed">Passed</label>
                  <label nz-radio nzValue="failed">Failed</label>
                </nz-radio-group>
              </nz-form-control>
            </nz-form-item>
          </div>
        </div>
      </div>
 </div>
