Checkbox, elements in a array

Checkbox, elements in a array

Halo,

in a formula I have a list with checkbox, if the user click on one box, the box value shut be put it in a array.
If the user click again on the same box, the value shut be remove from the array.

Here my php part:

foreach( $ob as $key => $value){
  ?>
  <tr>
   <td align="center" >
      <input type="checkbox" name="box4_<?php echo $value->id;?>" id="box4_<?php echo $key;?>" value="<?php echo $value->id;?>" onClick="takeBox( '<?php echo $value->id;?>' );">
   </td>
  </tr>
  <?php
}


Here my JS part with jQuery, I use the version 1.2.6:
arrMyValues = new Array();
var arrMyValueslength = arrMyValues.length;
function takeBox( newID )
{
   var bExist = false;
   $.each(arrMyValues, function(n, value){
      if( value == newID) {
         bExist = true;
      }
   });
   if( bExist == false ) {
     arrMyValueslength = ( arrMyValueslength +1 );
     arrMyValues[ arrMyValueslength ] = newID;
   }
}


What I make is not only bad
Have somebody a idea who could it work?
