validation issue (requiredPattern)

[rhanesoghlyan]

Due to this pattern (pattern="[0-9]*") my form-control is invalid when typing decimal number. When using other pattern plugin doesn't work

I'm having the same problem

you need to take out the form control from your auto validations by angular etc and do your own validation based on the form control value.

There is HTML validation for input field.
pattern="[0-9]*"

Found a workaround. Leave the pattern as it is (pattern="[0-9]*") in the input element and then clear and then set the needed validators on input focus.

    this.myForm.controls["hours"].setValidators(null);
    this.myForm.controls["hours"].setValidators(
      Validators.pattern(/^[+]?([0-9]+(?:[\.][0-9]*)?|\.[0-9]+)$/)
    );
    Object.keys(this.myForm.controls).forEach(key => {
      this.myForm.controls[key].markAsDirty();
    });
    this.myForm.updateValueAndValidity();
