如何使用jQuery从两个表选中的复选框中获取值？

Question

Here I have two tables, and in each table I have checked boxes. I am getting the checked values from both, but I am saving in two different arrays and combining to into a single one.

Is there any way to get the checked checkbox values from both tables, but only from these tables?

My Attempt:

 var First = [];
 var Second = [];
 First = $("#table1 input:checkbox:checked").map(function () {
     First[i] = $(this).val();
     return $(this).val();
 }).get();
 Second = $("#table2 input:checkbox:checked").map(function () {
     Second[i] = $(this).val();
     return $(this).val();
 }).get();

 var subjes = First + Second;

Just use a selector that selects checkboxes in both tables before you map them :

var boxes  = $('input:checkbox:checked', '#MainContent_CBLFYSubjects, #MainContent_CBLSYSubjects'),
    subjes = $.map(boxes, function(el){
        return el.value;
    });
