how to check the value of checkboxes in each row of table dynamically using javascript or jquery

I have a table in which values are dynamically added from database as below:

    var row = table.insertRow(i);
i = i+1;
// Insert new cells (<td> elements) at the 1st and 2nd position of the new <tr> element:
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
var cell5 = row.insertCell(4);
var cell6 = row.insertCell(5);
var cell7 = row.insertCell(6);
var cell8 = row.insertCell(7);
var cell9 = row.insertCell(8);
var cell10 = row.insertCell(9);
var cell11 = row.insertCell(10);

// Add some text to the new cells:
cell1.innerHTML = '$name';
cell2.innerHTML = '$name2';
cell3.innerHTML = '$lastname';
cell4.innerHTML = '$lastname2';
cell5.innerHTML = '$mellicode';
cell6.innerHTML = '$estekhdamnum';
cell7.innerHTML = '$email';
cell8.innerHTML = '$username';
cell9.innerHTML = '$password';
cell10.innerHTML = '$id';
var checkbox = document.createElement('INPUT');
checkbox.type = 'checkbox';
checkbox.name = 'checkbox[]';
checkbox.value = 'i-1';
cell11.appendChild(checkbox);

I would like to add a button at the end of the table that when I click it, it checks all the check boxes, recognizes the row of the checkbox and do some query.

$('tr').click(function(){

}); 

I shouldn't use 'tr' here I think but I don't know how to recognize the check boxes and see if it is checked or not and recognize the row of the checked checkbox.

thanks for your answer in advance.
