How this jQuery snippet works:
$('#myInput').on('blur', function() {...});: This listens for when the input field loses focus (blur event).$(this).val(): Retrieves the current value of the input field.replace(): Removes any leading or trailing spaces from the input string.$(this).val(trimmedValue): Updates the input field with the trimmed value.
Demo

var inputValue = $(this).val();
var trimmedValue = inputValue.replace(/^\s+|\s+$/g, '');
$(this).val(trimmedValue);
