    Checkbox values in a table needed?

    I am trying to get the values per row per checkboxlist. Here is my code... any help would be great.

    PHP Code:
    $pages =  "4";
    $size "4"

        print 
    '<form id="myform" name="form1">';
        print 
    '<div id="editions" style=" width:800px; height:500px; overflow:auto">';
        print 
    '<h2>Select Editions</h2>';
        print 
    "<table id='mytable' name='table1' border=1 cellpadding=7 width=50% height=50% align='center'>\n";
        print 
    '<tr>';
        print 
    '<th>Page - Editions</th>';
        print 
    '</tr>';
          for(
    $x 1$x <= $pages$x++) :
            print 
    "<td id='page_$x' class='page_button' align='center' >Page $x -";
              for(
    $i 1$i <= $size$i++) :
                print 
    "<input type='checkbox' class='ebutton' id='etype_$x' name='checks[]' value='0$i' /> 0$i";
              endfor;
            print 
    "</td>";
            print 
    '</tr>';
          endfor;
        print 
    '</div>';
        print 
    '</form>'
    Code:
      $(document).ready(function() {
        $(".ebutton").click(function() {
    
        var idp = $(this).attr("id").split("_");
        var page_num = idp[1];
        var hidden_id = "#etype_page_" + page_num;
    
        var ins = document.getElementsByTagName('input');
        var i;
        var j=0;
        var editions= new Array();
        for(i=0;i<ins.length;i++) {
        if(ins[i].type=="checkbox")
          editions[j]=ins[i].value;
          j++;
        }
        alert(editions);
    
         if($(hidden_id).length < 1) {
           $("#base").append('<input type="hidden" id="etype_page_'+ page_num +'" name="'+ page_num +'"  value="'+ editions +'" class="hidden_edtype" custom="' + editions +'">');
         } else {
           $(hidden_id).val($(this).val());
         }
           update_eShow();
         });
      });
    
      function update_eShow() {
        $("#eShow").html('');
        $(".hidden_edtype").each(function() {
          var page = $(this).attr("name");
          var value = $(this).attr("custom");
          <!--var value = $(this).val();-->
          $("#eShow").append('page:' + page + ' values:' + value +'<br>');
        });
      }
    If you need more information please let me know. Also this is a popup window so i am trying to use Javascript to get the values and pass them to another page at runtime.

    Thanks,
    Rev Phil

    I have created a Fiddle page that has the problem in it if anyone can assist. Its an HTML table with 2 rows of checkboxes. I need to get the checked data per row, and all I can figure out is how to get all checked values... Here is the link if someone can assist: http://jsfiddle.net/RevPhil/yqh3x/

    I modified the id on the PHP to this...

    Code:
    print "<input type='checkbox' class='ebutton' id='etype_[$x]' name='checks[]' value='0$i' /> 0$i";
    and the java to:
    Code:
     
     $(document).ready(function() {
        $(".ebutton").click(function() {
    
        var idp = $(this).attr("id").split("_");
        var page_num = idp[1];
    
    // get editions checked /
       var editions='';
       document.getElementById("editions").style.visibility="visible";
       var elements = document.getElementById("myform").elements;
       for(var i=0; i< elements.length;i++){
          if(elements[i].type == 'checkbox' && elements[i].checked)
             editions = elements[i].value ;
       }
    
          var hidden_id = "#etype_page_" + page_num;
          page_num = page_num.replace(/[\[\]']+/g,''); //remove brackets
          if($(hidden_id).length < 1) {
            $("#base").append('<input type="hidden" id="etype_page_'+ page_num +'" name="'+ page_num +'"  value="'+ editions +'" class="hidden_edtype" custom="' + editions +'">');
          }else{
            $(hidden_id).val($(this).val());
          }
    
          update_eShow();
        });
      });
    
      function update_eShow() {
        $("#eShow").html('');
        $(".hidden_edtype").each(function() {
          var page = $(this).attr("name");
          var value = $(this).attr("custom");
          $("#eShow").append('page:' + page + ' value:' + value +'<br>');
        });
      }
    My results are now:
    page:1 value:01
    page:1 value:02
    page:2 value:01
    page:2 value:02

    How can I combine the like pages and values to read
    page:1 value:01,02
    page:2 value:01,02
