Show alert/message to user if tries to drag or select click on bar above max limit value.

[RajasekharKadasani]

i need to show message to user if he tries to select the value above max limt value, I am updating Max value dynamically the max vaue will be changing fine,but user ties to select above range i should show notification to user that he cannot select above max value. If he clicks in range it should not show..

ng5-slider [(value)]="currentStepIndex" 
     (valueChange)="stepValueChange($event)" [options]="options" ></ng5-slider>


 options: Options = {
    floor: 1,
    ceil: 1,
    step: 1,
    showTicks: true,
    showTicksValues: true,
    tickStep: 1,
    minLimit: 1,
    **maxLimit: 1,**
        showSelectionBar: true,
  };

i will change maxLimit value using below function

someFunc(maxLimit:number ){
const newOptions: Options = Object.assign({}, this.options);
    newOptions.maxLimit = maxLimit + 1;
    this.options = newOptions;
}
