Check boxes values returned and added to string

I am trying to take a row of checkboxes in a table and for each TD in the table it needs to check if the checkbox is ticked, is so it is a 1 and else its 0. I need a for loop where I will be able to loop over each td, determin if it is checked and if so add a 1 to a binary string or else add a 0 to the binary string.

This should end with each tr having its own unique binary string from the checkboxes that have or have not been ticked. I will also want to set up each tr with its own unique ID.

The below code is what I have so far but am presumming I am going in the wrong direction.

Any help appreciated. Thanks

[ { ID: 000, binary: 0101010101 }  ]
function generate(){


$("#actionTable>tbody").children("tr").each(function(i, rowitem){
    $(rowitem).children("td").each(function(index, item){
        if (index == 0){
            var amid = $(item).data("amid");
        }

        else {
            //Handle checkbox
            var checked = $(item.firstChild).prop('checked')
        }
    });
});

}
