Angular2 如何将数据传递到模态框中

Question

我是一名新手，正在学习 Angular2 + TypeScript。我需要通过单击表格中的按钮来实现确认弹出框。

这是表格：

<div style="margin-top: 10px">
    <table id="recruitersTable" class="table table-striped center" [ngBusy]="data">
        <tr>
            <th>{{ 'RECRUITER_NAME_AND_SURNANE_COLUMN' | translate }}</th>
            <th>{{ 'RECRUITER_CODE_COLUMN' | translate }}</th>
            <th>{{ 'RECRUITER_ACTION_DOLUMN' | translate}}</th>
            <th></th>
        </tr>
        <tr *ngFor="let recruiter of recruiters">
            <td>{{ recruiter.Name }}</td>
            <td>{{ recruiter.Code }}</td>
            <td>
                <a class="btn btn-xs btn-default" data-target="#confirm" role="button" data-toggle="modal">
                    <span class="glyphicon glyphicon-ban-circle"></span>
                </a>
            </td>
            <td></td>
        </tr>
    </table>
</div>

这是确认模态框

<div id="confirm" class="modal fade in" aria-labelledby="modallabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <button class="close" data-dismiss="modal" aria-hidden="true"><span class="glyphicon glyphicon-remove"></span></button>
            <h3 id="modalLabael">Block recruiter</h3>
        </div>
        <div class="modal-body">
            <h3 id="modalLabael">Are you sure that you want block this recruiter?</h3>
        </div>
        <div class="modal-footer">
            <button class="btn btn-danger" data-dismiss="modal" aria-hidden="true">Cancel</button>
            <button class="btn btn-success" (click)="BlockRecruiter(recruiter.code)">Block</button>
        </div>
    </div>
</div>

我需要在确认模态框上点击“成功”按钮后，在另一个div中实现功能。有人能解释一下吗？

模态框是单独的组件还是同一个组件？ - silentsod

组件分离 - Dima Grigoriev

Answer 1

你可以使用EventEmitter，如果你的模态组件被包含在父组件中-在这里查看-> https://angular.io/docs/ts/latest/api/core/index/EventEmitter-class.html 或者你可以使用一个返回Subject作为observable的service。父组件可以订阅observable，而模态框在确认时会通知service。在这里查看alert.service的编写和使用-> Angular 2: Displaying icons in navbar on authentication
