JavaScript frameworks like jQuery have played a significant role in simplifying web development tasks, such as implementing a datepicker. However, as the movement towards modern JavaScript and lightweight web structures gains momentum, developers are increasingly opting to convert existing jQuery code into plain JavaScript. This article focuses on achieving such a transition for the jQuery datepicker by utilizing an onclick event.

Setting Up the Environment

Before jumping into the code conversion, ensure that your environment is ready for JavaScript execution. There are no additional libraries required for implementing a datepicker using plain JavaScript. All modern browsers support the Date object and related functionalities natively.

Explanation of the Code

HTML Structure: The code starts with an input field that serves as a button, triggering the datepicker when clicked.

JavaScript Function createDatePicker: This function attaches to the onclick event of the input field. It generates a hidden date input.

Date Input: A new <input> of type date is created, which uses the browser's built-in datepicker functionality. This HTML element is displayed next to the click-triggering input.

Event Listeners: An event listener captures the change event on the date input, ensuring the original textbox is populated with the chosen date value.

User Interaction: Upon selection, the temporary date input element is removed, restoring focus to the main input field.

Conclusion

Converting jQuery functionalities to vanilla JavaScript might involve creative approaches, such as leveraging native HTML5 elements—in this case, the date input type. This concerted focus on JavaScript not only makes the code more maintainable and flexible but also reduces reliance on external libraries. Embracing these strategies encourages web development complexity reduction without compromising feature richness.
