Angular 2 - 获取指令或组件中的所有 @input()

Question

有没有办法在角度 2 中使用@Input装饰器获取所有组件或指令属性？

Answer 1

If you want to get all inputs value you can go with ngOnChanges hook.

class MyComponent implements OnChanges {
  @Input() myProp: any;
  ngOnChanges(changes: SimpleChanges) {
    console.log('ngOnChanges - myProp = ' + changes['myProp'].currentValue);
  }
}
