Question

我正在尝试根据选中的复选框动态添加行。这里的想法是复制选定的行。例如，最初只有一行。在选中与此行对应的复选框时，它会创建一个副本。如果我更改新添加的行中的下拉值并复制它，由于我的硬编码，它无法执行此操作。我怎样才能带来这种动态？

<head>
    <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
    <script>
        $(document).ready(function() {
            $("#DuplicateRow").click(function() {
                var checkboxValues = [];
                $('input[type="checkbox"]:checked').each(function() {
                    //alert('hi') 
                    var row = document.getElementById("row"); // find row to copy
                    var table = document.getElementById("tabletomodify"); // find table to append to
                    var clone = row.cloneNode(true); // copy children too
                    clone.id = "row"; // change id or other attributes/contents
                    table.appendChild(clone); // add new row to end of table
                });
            });
        });
    </script>
</head>

这个怎么样..这有效，你手动将所有已更改/选定的选项从实际行复制到克隆行

$(document).ready(function(){
$("#DuplicateRow").click(function(){
var checkboxValues = [];
$('input[type="checkbox"]:checked').each(function(){
var $chkbox=$(this);
var $actualrow = $chkbox.closest('tr');
var $clonedRow = $actualrow.clone();
$clonedRow.find("select").each(function(i){
this.selectedIndex = $actualrow.find("select")[i].selectedIndex;
})
$chkbox.closest('#tabletomodify').append( $clonedRow );
});
});
});

根据复选框选中动态jquery重复行
