However, developers often face challenges when trying to set default dates intelligently—particularly, showing a default date only when the input field is empty or invalid. If you've stumbled upon this problem, you're not alone. Let's break down the solution. The Problem You want to initialize Flatpickr such that: It displays the date specified in the input field if it exists and is valid. If the input field is empty or contains an invalid date, then it should default to the current date. Here's what you were initially trying: [[See Video to Reveal this Text or Code Snippet]] The issue here is that setting defaultDate directly to new Date() causes it to always override the input value, making it impossible to keep a user-specified date. The Solution To achieve the desired behavior, you need to implement a conditional check: provide a default date only if the input value is null or empty. Step-by-step Guide Create a Function to Handle Default Value Logic You can set up a function that checks the input value before assigning it to the defaultDate. Modify Your Initialization Code Update your Flatpickr initialization code to include this function. Here’s the modified example: [[See Video to Reveal this Text or Code Snippet]] Explanation Function getDefaultDate(): This function checks the value of the input field. If the value is empty or invalid (not a valid date), it returns the current date. Otherwise, it will still attempt to use the value present. Flatpickr Initialization: When the initialization runs, it will call getDefaultDate() to determine the proper default date dynamically based on user input. Conclusion By implementing these steps, you will allow Flatpickr to conditionally set a default date, only when the user hasn't entered a valid date. This enhances user experience by providing flexibility and maintaining previous selections. Now you can enjoy using Flatpickr effectively without worrying about losing user inputs!
