depends on structure of your table.
in general way it should be something like:

// first we get all rows
var rows = new Array();
rows = document.getElementById("tableId").getElementsByTa gName("TR");

// next we can loop through this array and get all cells
for(var i = 0; i < rows.length; i++) {
var cells = new Array();
cells = rows[i].getElementsByTagName("TD");
}

so you can loop through cells for each row to check if there is <input
type="checkbox" /> and if it is checked.

ok, similar way to get all checkboxes is:

document.getElementById("tableId").getElementsByTa gName("INPUT");

then loop through all input to check 1)if it's type is checkbox and 2)if
it is checked.

You have a feasible answer.

Consider naming your checkboxes with the same id. Then you can say

var checkboxesArray = document.getElementById("checkboxId")

and then loop through the array of checkboxes.
