submit - Multiple Form Actions to different pages / different target windows -

i have form on page needs have multiple form actions associated it. i'm using following script in conjunction following code achieve this:

<script>     function submitform(action)     {         document.getelementbyid('summary').action = action;         document.getelementbyid('summary').submit();     } </script>   <form action="go-gold.php" method="post" enctype="multipart/form-data">  <input type="image" id="arrow" name="go_back" onclick="submitform('go-gold.php')" value="go_back" src="images/arrow_back.png" class="submit_button" /><br>  <input type="image" id="arrow" name="submit_form" onclick="submitform('registration.php')" value="submit_form" src="images/arrow.png" class="submit_button" /> </form> 

the first button needs "go back" within same browser window (self), , second button needs submit info new window (blank). how modify code achieve this? putting "target" functions within input type doesn't work, , putting target in form tag makes both submit buttons submit same window.

thanks!

easy jquery, have identical ids 2 separate form elements. should have these distinct ids unless want use class name. php can submit forms same page using $_server superglobal using $_server['php_self'] forms action name.

  <script>     $(document).ready(function() {         $(".submit_button").click(function() {             clickval = $(".submit_button").val();             if(clickval == 'go_back') {                 //do go stuff             }              if(clickval == 'submit_form') {                 // actions other page             }         });     });     </script>      <form action="go-gold.php" method="post" enctype="multipart/form-data">         <input type="image" value="go_back" src="images/arrow_back.png" class="submit_button" /><br>        <input type="image" value="submit_form" src="images/arrow.png" class="submit_button" />     </form>
