    get names of buttons

    Hello.

    I am new to Javascript and JSP. I would like to have multiple submit
    buttons in a form. Each button has a different action? How can I go
    about doing that? How can I obtain the button's name or id?

    Thank you

          Usual way of doing :

          - All submit-buttons have same name
          - each button has its own value according to some action
          - code server-side uses the name of submit button to know
          what action to serve (the submit-button's value)
          with the other elements of the form
          - javascript uses :
          1) an onclick attributed to the button
          - most simple :
          to give the value of button to a global variable
          <input type=submit value="Do That" name="send"
          onclick="ToDo=t his.value">
          - or a function to do somethin with the elements of the form
          2) the attribute 'onsubmit' given to the tag 'form'


          That can give :

          <html>
          <script type="text/javascript">
          var ToDo = '';
          function validate () {
          return confirm('Ok for this action : '+ToDo+' ?');
          }
          </script>
          <form action="javascr ipt:alert('mess age sent')"
          onsubmit="retur n validate();">
          <p><input type=submit name="send" value="First action"
          onclick="ToDo=t his.value">
          <p><input type=submit name="send" value="Second action"
          onclick="ToDo=t his.value">
          <p><input type=submit name="send" value="Third action"
          onclick="ToDo=t his.value">
          </form>
          </html>

              No, that is not possible. You need to have different forms for different
              form actions. However, the server-side resource to receive the form data
              as referred to by one form element's `action' attribute can differentiate
              between the action to be performed according to the used submit button.
              How can I go about doing that? How can I obtain the button's name or id?
              Only the activated submit button is included in the list of successful
              controls. So you could use the same name and evaluate the different value
              server-side. However, it becomes more difficult with automated i18n.

              Another approach is to use a different control name for each submit button.
              Since only the activated submit button is considered a successful one, you
              only get its name in the request and not the names of the other buttons.

              This has nothing to do with "Javascript ", nor should client-side scripting
              be used to resolve it (unless further client-side actions are necessary on
              submit.)

              BTW, JSP is JavaServer Pages (not JavaScript Pages), which is therefore
              off-topic here and on-topic in comp.lang.java. *. Java != JavaScript.
