Using jQuery, we can easily hide and restore the placeholder when the user clicks on the field

you can use jQuery to hide the placeholder when a user focuses on a field and restore it when they blur (leave) the field. Here's an example:

Input field HTML: 

jQuery Code:

$(document).ready(function () {
	const $input = $('#nameField');

	$input.on('focus', function () {
		$(this).data('placeholder', $(this).attr('placeholder')); // Save placeholder
		$(this).attr('placeholder', ''); // Remove placeholder
	});

	$input.on('blur', function () {
		$(this).attr('placeholder', $(this).data('placeholder')); // Restore placeholder
	});
});

Explanation

Focus Event:

• Triggered when the input field is clicked or gains focus.
• Save the current placeholder value in a custom data attribute (data('placeholder')) and clear the placeholder.

Blur Event:

• Triggered when the input field loses focus.
• Restore the placeholder from the saved data attribute.
