I'm trying to get values of a table with jQuery. Every table row has a checkbox at the begining. How can I copy data of each row, but only if it's checked. All checkboxes and rows has the same class. Now I'm using this code:

var table = $("table");
    var allRows = [];
    table.find('tr').each(function (i, el) {
        if($('input:checkbox:checked').length > 0){
            var $tds = $(this).find('td'),
            name = $tds.eq(2).text(),
            surname = $tds.eq(4).text();
            allRows.push(surname+";"+name+";"+"\n");
        }
    });
    allRows = allRows.join("");

But it's getting all the lines. How can I do this only for lines which are checked?

$('.theClass:checkbox:checked') will give you all the checked checkboxes with the class theClass. See also Get all checked checkboxes

As of now you are checking any checkbox is checked. the condition needs to be changed.

You need to check the :checked state of the chechbox in current row while iterating.

if($(this).find(':checkbox:checked').length > 0){
   //your existing code
}
