我再次陷入困境，我不知道如何继续，因为我已经对自己的jQuery函数视而不见了。
我想要的是将主表的列保存到数组中，在那里我可以检查哪一个是空的。然后我想将值发送到表。 （第3功能）。
请帮忙！我被困了-_-
JQUERY
//function to save input value below the textbox in a "list" of columns.
$('#SaveButtonId').click(function () {
$('.table2 tr .table2td').text($('input[type="text"]').val());
$('input[type="text"]').val('');
});
//function to iterate through .mytd columns and put them in an array.
var columns = [];
$('.table').each(function() {
$(this).find('.mytd:text').each(function() {
columns.push($(this).val());
});
});
//function to send value to empty column
$('#ActivateButton').click(function() {
$('.table tr .mytd').text($('.table2td').val());
});

这里是代码的fiddle。
//function to save input value below the textbox in a "list" of columns.
$('#SaveButtonId').click(function () {
$('.table2 tr .table2td').text($('input[type="text"]').val());
$('input[type="text"]').val('');
});
//function to iterate through .mytd columns and put them in an array.
var columns = [];
$('.table').each(function() {
$(this).find('.mytd:text').each(function() {
columns.push($(this).val());
});
});
//function to send value to empty column
$('#ActivateButton').click(function() {
$('.table tr .mytd').text($('.table2td').val());
});

也许你会找这样的东西来循环元素？
$("#table-columns tr td").each(function() {
var content = $(this).html();
});
