    Conditional onsubmit events

    Hi,

    I have a form that has 2 submit buttons. The form action is a php
    script. What I'm trying to do is to execute a different javascript
    function depending on which submit button is pressed. So far I've tried
    the following with no success. In the code below, a different function
    would execute based on the value of the "flag" variable.

    <HTML>
    <HEAD>
    <SCRIPT TYPE="text/javascript">
    function some_function() {
    alert(flag);
    }
    </SCRIPT>
    </HEAD>
    <BODY>
    <form name="form1" action="./submit.php" method="POST"
    onsubmit="javas cript:some_func tion()">
    <input type="text" name="name" size=50>
    <input type="submit" name="submit1" value="Submit 1"
    onclick="javasc ript:var flag=1;">
    <input type="submit" name="submit2" value="Submit 2"
    onclick="javasc ript:var flag=2;">
    </form>
    </BODY>
    </HTML>


    <?php
    if ($_POST[submit1]) {
    echo "submit1";
    }

    if ($_POST[submit2]) {
    echo "submit2";
    }
    ?>

      Hello,
      you sholud try this
      first write this function into head section
      function checkpressedbtn (obj)
      {
      if (obj.value == "Submit 1")
      ------- go to your function -----------
      else
      ------- go to another function -----------
      }

      then change your buttons like this
      input type="submit" name="submit1" value="Submit 1"
      onclick="javasc ript: checkpressedbtn (this)">


      <input type="submit" name="submit2" value="Submit 2"
      onclick="javasc ript: checkpressedbtn (this)">

          Get rid of the "javascript :" labels and the "var" keyword, which
          makes the flag variable local. You want it to be global.

          <HTML>
          <HEAD>
          <SCRIPT TYPE="text/javascript">
          function some_function() {
          alert(flag);
          }
          </SCRIPT>
          </HEAD>
          <BODY>
          <form name="form1" action="./submit.php" method="POST"
          onsubmit="some_ function()">
          <input type="text" name="name" size=50>
          <input type="submit" name="submit1"
          value="Submit 1" onclick="flag=1 ;">
          <input type="submit" name="submit2"
          value="Submit 2" onclick="flag=2 ;">
          </form>
          </BODY>
          </HTML>

                  The form might be submitted without either onclick function running - it
                  may be submitted by pressing the enter key or javascript may be disabled
                  or unavailable.

                      Thanks for all the suggestions. I got it working through some additions
                      and changes to my original script. I prefer not to put the code online
                      since the objective was to partially work around popup blockers while
                      conditionally redirecting the application via a popup window, and at
                      the same time posting the data to a server side php script. I'd rather
                      keep these types of scripts off the newsgroups and out of the hands of
                      potential abusers.
