javascript - angular 2 formbuilder min max validation -

i using angular 2 formbuilder create form. want input positive values amount field.(minvalue 0 , maxvalue 100) how can perform min , max validation angular2 formbuilder.

html code

 <form class="form-horizontal"               novalidate               (ngsubmit)="splitcharges()"               [formgroup]="splitchargeform" >     <input  type="number" id="sequenceid"  placeholder="amount" formcontrolname="amount"  >  </form> 

angular component

 constructor(private fb: formbuilder){}   ngoninit() {         this.splitchargeform = this.fb.group({           amount: ['', validators.required],   // want set min=0 , max=100 validations field           percentage: ['', validators.required]         });     } 

this should want:

amount: ['', [validators.required, validators.min(0), validators.max(100)]],
