to save values in an array form a table that is dynamically generated

[syedshaffee]

i have made a table in asp classic that generates values dynamically.Wri tten a jQuery for retrieving the values from this table by clicking on a checkbox & displaying it in a msgbox i want to save it in an array assuming the customer will select more than one row

 $(document).ready(function () {    
    //assigning alternative row style
$("#Table_Data tr:even").addClass("evenrow");
$("#Table_Data tr:odd").addClass("oddrow");
    
 $("#Table_Data tr").click(function(){
   $(this).find(':checkbox').attr('checked', ! $(this).find(':checkbox').attr('checked'));    
   if($(this).find(':checkbox').attr('checked'))
        {
              var html = '';
$(' #Table_Data td').click(function() {
    html = $(this).text();
    alert(html);
    
});

        }
        else
        {
            $(this).removeClass('highlight');
              $(this).addClass('evenrow');
        }
});

My problem is:
1)array size
2)only once the value should be save in an array
3)The back ground of the row doesn't change

1. Use [Array].length if you want the length of an array.
2. Don't use arrays then. Use associative arrays (which all objects are) and ids:
[code=JavaScript]
r={};
r.length=0;
function clickon(id){ r[id]=1; r.length++; }
function clickoff(id){ delete r[id]; r.length--; }
function printr(r){ var o=""; for(var a in r){ o+=a+","; } o=o.slice(0,-1); return o; }
[/code]
3. I totally don't get this.
