I have a large HTML form with multiple input fields (one in each row). Among these I have several fields with a specific class that appear left from a button. There are no other buttons or fields in these rows so they only contain the field and button as below. How can I get the ID of such a field when clicking on the button right from it, i.e. closest to it ? All fields in question look like this: <input type="text" class="dateField" data-date-format="yyyy-mm-dd" id="field1" name="field1" /> All buttons in question look like this: <button type="button">Select Date</button> Thanks for any help
