下面是使用第一个组合框自动完成工作正常的代码。如果我只是复制粘贴组合框就可以了，但是当按钮上动态创建第二个组合框时，自动完成功能无法正常工作？

我在你的代码中观察到某些与html有点不正确的观点。你有机会写的很快，所以请忽略这些要点
所以在这里我已经更改了你的loada（）函数替换然后它将起作用。
var counter = 0;
function loada() {
// document.getElementById("two").innerHTML = document.getElementById("one").innerHTML;
$("#one").clone().find('select').addClass('newControl' + counter).appendTo("#two");
$('.newControl' + counter).combobox();
counter++;
}
