How to fetch the value of name element of input submit button present in a form from a servlet

Question

How can I fetch the value of name(which is either 1 or 2) in the forms below, in the RegisterRedirect servlet?

....

<tr>
        <td><form action="RegisterRedirect" method="post">
            <input type="submit" name="1" value="Edit"></form></td>
        <td><form action="RegisterRedirect" method="post">
            <input type="submit" name="2" value="Delete"></form></td>
</tr>

.....

Is there an attribute property? E.g. element -> attribute('name') — user328414, Dec 05 '19 at 02:24

You can get all the names first. Since you only have one element, get the next one. So in your doPost method from RegisterRedirect:

Enumeration<String> names = request.getParameterNames();
String firstAndOnlyElem = names.nextElement();
System.out.println(firstAndOnlyElem);
System.out.println(request.getParameter(firstAndOnlyElem));

You will get the 1 and Edit clicking on the submit button from the first form.
