您有两个选项：
1.创建第三个方法来 Package 这两个方法。这样做的好处是你在模板中放置了更少的逻辑。
1.否则，如果您想在ng-click中添加2个调用，则可以添加';“edit($index)之后就这样
ng-click="edit($index); open()"
请参阅此处：http://jsfiddle.net/laguiz/ehTy6/

您可以使用';'

ng-click="edit($index); open()"

很多人使用（点击）选项，所以我也会分享这个。

<button (click)="function1()" (click)="function2()">Button</button>

添加多个函数的标准方法

<button (click)="removeAt(element.bookId); openDeleteDialog()"> Click Here</button>

或

<button (click)="removeAt(element.bookId)" (click)="openDeleteDialog()"> Click Here</button>

试试这个：

• 创建函数集合
• 创建一个循环访问并执行集合中所有函数的函数。
• 将函数添加到html

array = [
    function() {},
    function() {},
    function() {}
]

function loop() {
    array.forEach(item) {
        item()
    }
}

ng - click = "loop()"

遵循以下

ng-click="anyFunction()"

anyFunction() {
   // call another function here
   anotherFunction();
}

<!-- Button trigger modal -->
                <button type="button" (click)="open(content)" style="position: fixed;  bottom: 0;  right: 130px;"
                    class="btn col-sm-1  btn-Danger" >
                    Reject
                </button>
                  
                  

                <ng-template #content let-modal>
                    <div class="modal-header">
                      <h4 class="modal-title" id="modal-basic-title">Profile update</h4>
                      <button type="button" class="btn-close" aria-label="Close" (click)="modal.dismiss('Cross click')"></button>
                    </div>
                    <div class="modal-body">
                     
                        <div class="mb-3">
                          <label class="bg-danger text-light" for="Reject">Reason For reject</label>
                          
                            <textarea   matInput placeholder="  Reject" [(ngModel)]="asset_note">{{note}}</textarea>
                
                        </div>
                    </div>
                    <div class="modal-footer">
                        <!-- -->
                      <button type="button" class="btn btn-outline-dark" (click)="reject();modal.close('Save click') ">Save</button>
                    </div>
                  </ng-template> 

**.ts file**
open(content: any) {
    this.modalService.open(content, {ariaLabelledBy: 'modal-basic-title'}).result.then((result) => {
      this.closeResult = `Closed with: ${result}`;
    }, (reason) => {
      this.closeResult = `Dismissed ${this.getDismissReason(reason)}`;
    });
  }

  private getDismissReason(reason: any): string {
    if (reason === ModalDismissReasons.ESC) {
      return 'by pressing ESC';
    } else if (reason === ModalDismissReasons.BACKDROP_CLICK) {
      return 'by clicking on a backdrop';
    } else {
      return `with: ${reason}`;
    }
  }

close()
{

this.getDismissReason(ModalDismissReasons.ESC);
}

以下哪一项是最佳做法（选项1或选项2）
1.=“删除在（元素.bookId）; openDeleteDialog（）"〉单击此处
1.单击此处，然后单击“删除”按钮。

ng-click "$watch(edit($index), open())"
