【问题描述】：

尝试将所选项目从一个列表移动到另一个，但附加 dom 元素不起作用：

//Assign action modules
    $('#Modal_Task #assigned_module').click(function () {
        var list = $("#Modal_Task .unassigned li.ui-selected");
        $('#Modal_Task .assigned').append(list);
        list.remove();
    });


//UnAssign action modules
    $('#Modal_Task #unassigned_module').click(function () {
        var list = $("#Modal_Task .assigned li.ui-selected");
        $('#Modal_Task .unassigned').append(list);
        list.remove();
    });

【解决方案1】：

你有错别字ui-selectee -> ui-selected
你添加元素然后立即删除它。添加clone。

$('#Modal_Task #assigned_module').click(function () {
    var list = $("#Modal_Task .unassigned li.ui-selected");
      $('#Modal_Task .assigned').append(list.clone());
    list.remove();
});


$('#Modal_Task #unassigned_module').click(function () {
    var list = $("#Modal_Task .assigned li.ui-selected");
    $('#Modal_Task .unassigned').append(list.clone());
    list.remove();
});
