angular - 如何关闭 Angular 2 中的模式？

Question

我希望用户单击“提交”按钮并自动关闭模式。

如果我添加 data-dismiss="modal"在提交<button> , 它不会运行 submitComments() .

我试着做类似 $('#myModal').modal('hide'); 的事情, 但没有成功。

那么如何在 Angular 2 中关闭模态框呢？谢谢

<button type="button" class="btn btn-info" data-toggle="modal" data-target="#myModal">Open Modal</button>

<div id="myModal" class="modal fade">
     <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body">
                <form (ngSubmit)="submitComments()">
                    <div class="form-group row">
                        <label class="form-control-label col-sm-2">Comments:</label>
                        <div class="col-sm-10">
                            <textarea class="form-control" rows="3"></textarea>
                        </div>
                    </div>
                    <div class="form-group row">
                        <div class="col-sm-offset-2 col-sm-10">
                            <button type="submit" class="btn btn-default">Submit</button>
                        </div>
                    </div>
                </form>
            </div>
        </div>
    </div>
</div>

.

submitComments() {
    // I want to do something like $('#myModal').modal('hide'); here.
}

Answer 1

使用@ViewChild

将 #closeBtn 添加到带有 data-dismiss="modal" 的元素中

<a><i class="fa fa-close" data-dismiss="modal" #closeBtn></i></a>

组件 html

<div class="modal fade" id="yourModalId">
  <div class="modal-dialog modal-lg">
    <div class="modal-content">
      <div class="modal-header">
        <a><i class="fa fa-close" data-dismiss="modal" #closeBtn></i></a>
      </div>
      <div class="modal-body">
      </div>
      <div class="modal-footer">
      </div>
    </div>
  </div>
</div>

使用 this.closeBtn.nativeElement.click(); 触发点击事件将关闭您的模式。

组件 typescript

import {ViewChild, ElementRef} from '@angular/core';
@Component({
    moduleId: ...,
    selector: '.',
    templateUrl: '.',
    styleUrls: ['.']
})
export class yourClass {
    @ViewChild('closeBtn') closeBtn: ElementRef;

    yourFunction() {
        //do something
        ...
        ...
        //close your modal
        this.closeModal();
    }

    //call this wherever you want to close modal
    private closeModal(): void {
        this.closeBtn.nativeElement.click();
    }
}
