1. Comparing value is passed In next example value of the form control must be equal to current time.

Select time {{equalFormControl.errors | controlErrorResolver}}

2. Comparing control value is passed Here are two form controls that are required and end time has to be the same as start time.

Select start time {{equalForm.get('startTime').errors | controlErrorResolver}} Select end time {{equalForm.get('endTime').errors | controlErrorResolver}} Is form valid: {{equalForm.valid}}

1. Comparing value is passed In next example selected time must be strictly greater than current time.

Select time {{greaterFormControl.errors | controlErrorResolver}}

2. Comparing control value is passed Here are two form controls that are required and end time must be strictly greater than start time.

Select start time {{greaterForm.get('startTime').errors | controlErrorResolver}} Select end time {{greaterForm.get('endTime').errors | controlErrorResolver}} Is form valid: {{greaterForm.valid}}
