    dynamic submit action help

    hello!i will try to explain my problem here!forgive me from mu english
    i want to create buttons depented on some field in mysql.i managed to pass the variable value (how many buttons to make) with php and javascript.Now i want for each button to show some data from mysql(i guess i should call a fun with button parameter to do this) my problem is how to make each button act deferently?i try this
    Code:
    function addsubmit (fid)
{ for (i=0;i<num;i++){ //num is how many buttons to create

var newsubmit = document.createElement("input");
newsubmit.type = "submit";
newsubmit.id = "mysubmit"&+submitCount;
newsubmit.name = "mysubmit";
newsubmit.value =i;
fid.appendChild(newsubmit);
}
}
    and i call in body <body onLoad="return addsubmit(myfor m1)";>
    how can i make each button to call a function with maybe some parameter to show my results ? i also tried to modify above function
    Code:
    function addsubmit (fid)
{ for (i=0;i<num;i++){ //num is how many buttons to create

var newsubmit = document.createElement("input");
newsubmit.type = "submit";
newsubmit.id = "mysubmit"&+submitCount;
newsubmit.name = "mysubmit";
newsubmit.value =i;
[B]newsubmit.onclick =fun(i);[/B]
fid.appendChild(newsubmit);
}
}
    but with this when page is loaded it call tha function automatically without pressing the buttons.Sorry for the long length article but i try to explain my problem! tnx ina advance

      the onclick event handler (like any event handler) expects a function reference to be given, not a function return value.

      Code:
      function myfunc(evt)
{
    // function code
    // the event object is accessible through evt
}

elem.onclick = myfunc;

// with parameter 
function myfunc(param)
{
    // function code
}

elem.onclick = function (evt) { myfunc("some_value"); };

// with a Closure to pass variables
elem.onclick = function (p) {
    return function() { myfunc(p); };
}(param);

          thnx for your reply! i tried
          Code:
          newsubmit.onclick = function () {
                                   fun(i);
                                   };
          and worked like charm :)
          now i have something else that bugs me.i want each button to be named by a mysql table value.So a append my code
          Code:
          <?php
$connect=mysql_connect("localhost","admin","pass")
or die ("Check your server connection");
$db_found = mysql_select_db("mydb", $connect);
$SQL = "SELECT * FROM mytable ";
$result = mysql_query($SQL);
$num_r = mysql_num_rows($result);
while($nt=mysql_fetch_array($result)){
     $test[$num_r]=$nt['testing'];
}
          By here i have all the values of mysql table saved in an array $test.Now look at the script
          Code:
          ?>
<script language="javascript" type="text/javascript">
function addsubmit (fid){
   var num = "<?php echo $num_r; ?>";
    if (num >0) { 
          for (i=0;i<num;i++){
           var newsubmit=document.createElement("input");
               <?php $n=$num_r--;?>
               data="<?php echo $test[$n]; ?>";
               newsubmit.type = "button";
               newsubmit.id = "mysubmit";
               newsubmit.name = "mysubmit";
               newsubmit.value =data;
               newsubmit.onclick = function () {
                                   fun(i);
                                   }; 
               fid.appendChild(newsubmit);
          }
    }
}
          but with no result!if i try for test
          Code:
          data="<?php echo $test[2]; ?>";
          ,it doesnt work again,if i try
          Code:
          data="<?php echo $test; ?>";
          all the buttons are named Array.any ideas how will i make it work as i want ??

              I doubt that.

              but with no result!
              obviously, PHP is executed on the server and JavaSript on the client.
