";     $result = mysql_query($sql);     $i=1;     while($row=mysql_fetch_array($result)){          ?> <?php     $id = $row['id'];     $dater = $row['date'];     $flatnonam = $row['flatno_name'];     $addr = $row['adress'];     $subject = $row['subject'];     $body = $row['body'];     $soci = $row['societyn'];     $refnum = $row['refno'];     $letterh = $row['letterh'];          // split "dd-mm-yyyy" array of 3 elements         $ddate = explode("-", $dater);         // retrieve values         $month = $ddate[1]; // mm         $day = $ddate[2]; // dd         $year = $ddate[0]; // yyyy     {     ?>  <tr>             <td><?php echo $day.'/'.$month.'/'.$year; ?></td>             <td><?php echo $flatnonam; ?></td>             <td><?php echo $letterh; ?></td>             <td><?php echo $addr; ?></td>             <td><?php echo $subject; ?></td>             <td><?php echo $soci; ?></td>             <td><?php echo '#'.$refnum; ?></td>              <td>             <select name="menu1" id="menu1">                 <option value="" selected>pick website</option>                 <option value="letter/letter_print.php?id=<?php echo $row['id']; ?>">without letter head</option>                 <option value="letter/letter_print_nohead.php?id=<?php echo $row['id']; ?>">letter head</option>             </select>             </td></tr>      <?php }?>     <?php     echo "<br>";     $i++;     }      ?>   <!--this java script--> <script type="text/javascript">  var urlmenu = document.getelementbyid( 'menu1' );  urlmenu.onchange = function() {       window.open( this.options[ this.selectedindex ].value, '_blank','width=595,height=842,directories=no,titlebar=no,toolbar=no,location=no,status=no,menubar=no,scrollbars=no,resizable=no');  }; </script>

this code .only 1st 1 option working other not working. please in trouble. 2 days. or give solution. in 1 id how use options. trying 2 days not working.

as mentioned change id class since have multiple select. define onchange listener of them:

var urlmenus = document.queryselectorall('.menu1'); for(var = 0; < urlmenus.length; i++) {     urlmenus[i].onchange = function () {         window.open(this.options[this.selectedindex].value, '_blank', 'width=595,height=842,directories=no,titlebar=no,toolbar=no,location=no,status=no,menubar=no,scrollbars=no,resizable=no');     }; }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
