javascript - Angular2，inputmask ngModel绑定(bind)

我对ng2和inputmask有问题。例如我有这段代码
component.html

<div class="form-group col-sm-7">
  <label class="control-label" for="sender-phone">Phone *</label>
  <input type="text" [(ngModel)]="sender.phone" class="form-control" id="sender-phone" placeholder="Phone">
</div>

component.ts

ngAfterViewInit() {
  let phoneNumberInput = document.getElementById('sender-phone');
  let inputmask = new Inputmask('[phone]');
  inputmask.mask(element);
}

Inputmask工作正常。但是我的[(ngModel)]无法正常工作。有人知道我该如何解决我的问题？

您需要使用InputMask创建指令

@Directive({ selector: '[tdInputmask]' })
export class InputmaskDirective {
@Output('tdInputmaskUnmaskedValue') unmaskedValueEmitter = new EventEmitter();

@Input() set defaultValue (value: string) {
    //this._defaultColor = colorName || this._defaultColor;
}

@Input('tdInputmask') mask: string;

private el: HTMLElement;
constructor(el: ElementRef) {
    this.el = el.nativeElement;
}

ngAfterViewInit() {
   let inputmask = new Inputmask(this.mask);
    let elementCallback = () =>  {
        if (this.el.inputmask) {
            this.unmaskedValueEmitter.emit('7' + this.el.inputmask.unmaskedvalue());
            //if (!this.el.inputmask.isComplete()) {
            //    this.el.parentElement.classList.add('has-error');
            //} else {
            //    this.el.parentElement.classList.remove('has-error');
            //}
        }
    };

    inputmask.opts.oncomplete = elementCallback;
    inputmask.opts.onincomplete = elementCallback;
    inputmask.opts.onBeforePaste = (pastedValue: string) => {
        if (pastedValue[0] == '7' || pastedValue[0] == '8') {
            return pastedValue.slice(1);
        }
        return pastedValue;
    };
    inputmask.mask(this.el);
}
}

在HTML代码中，我使用

<input [tdInputmask]="'[phone]'" (tdInputmaskUnmaskedValue)="val3 = $event">
