    I am using a popup window
    in this I may be having n number of input checkboxes(here I have taken 4)
    like this <input type='checkbox' name='comments1' value='0' />
    so I will be naming it comments1, comments2, and so on.....

    and now to return it's values to parent window I am using this function

    function Done() {

    if (comments1.checked)
    MyArgs[1][0] = 1;
    else
    MyArgs[1][0] = 0;

    if (comments2.checked)
    MyArgs[1][1] = 1;
    else
    MyArgs[1][1] = 0;

    if (comments3.checked)
    MyArgs[1][2] = 1;
    else
    MyArgs[1][2] = 0;

    if (comments4.checked)
    MyArgs[1][3] = 1;
    else
    MyArgs[1][3] = 0;

    window.returnValue = MyArgs;
    window.close();
    }

    now can do something like
    if ( comments + i . checked) (not exactly like this )
    I want to put it in a loop until the length of comments ( that is may be 1 .. 10, length I can determine) .

    You can loop through the form elements and use a bit of regular expression to get as many checkbox values you want.

    Example:
    Code:
    var myArgs[1] = {};
     fucntion Collect(oForm)
     {
       var e=oForm.elements;
       for(var i=0;i<e.length;i++)
       {
     	if(e[i].type="checkbox" && e[i].name.match(/^comments([\d]+)$/))
     	{
     	  if(e[i].checked)
     		myArgs[1][RegExp.$1] = 1;
     	  else
     		myArgs[1][RegExp.$1] = 0;
     	}
     }
     
     //calling the function
     Collect(document.forms[0]);

    Hope this is useful.

    thx for reply pradeep,

    actually I have completed that task by some other way,

    but what you have given is intresting I would like to work on it later...and ask any doubts

    one immediate for me when I am looking at script is ( as not aware of RE in java script)
    ' RegExp.$1' do I need to place it as it is or is there any to I need to replace there..
