When working with forms that require users to select a date, you often need to prevent them from choosing past dates—especially for scenarios like booking appointments or making reservations. This is a common requirement in many applications, and luckily, HTML and JavaScript provide a simple way to handle this.
The element with type="date" allows users to pick a date easily. However, by default, the user can select any date, including past ones. To restrict users from selecting a date before the current day, you can use the min attribute in conjunction with JavaScript.
Here’s an example of a simple date input:
<input type="date" id="reservationDate" name="reservationDate" />
To prevent users from selecting a past date, you need to set the min attribute of the field. The min attribute specifies the minimum date that can be selected.
You can dynamically set the current date using JavaScript’s Date object, format it to the required YYYY-MM-DD format, and apply it to the min attribute.
For React users, here’s how you can integrate this into a TextField component:
import { TextField } from "@mui/material"; import { Field } from "formik"; const ReservationDateField = ({ touched, errors }) => { return ( <Field as={TextField} label="Reservation Date" type="date" name="reservationDate" fullWidth margin="normal" InputLabelProps={{ shrink: true }} InputProps={{ inputProps: { min: new Date().toISOString().split("T")[0], // Disable past dates }, }} error={touched.reservationDate && Boolean(errors.reservationDate)} helperText={touched.reservationDate && errors.reservationDate} /> ); };
Restricting past dates is essential in forms that manage future events like:
It improves user experience by preventing invalid date selections and reduces the likelihood of user error.
Disabling past dates is a simple yet powerful way to improve your forms. Whether you’re a beginner or an experienced developer, applying this technique ensures your users don’t accidentally select incorrect dates. This small step can make a big difference in your application's usability.
