我正在尝试使用 Jquery 克隆表单中的字段。

我试图在显示方面实现以下目标：

SELECT     SELECT     TEXT INPUT
RADIO      RADIO      RADIO  

Clone 1
SELECT     SELECT     TEXT INPUT
RADIO      RADIO      RADIO

Clone2
SELECT     SELECT     TEXT INPUT
RADIO      RADIO      RADIO


What I end up getting is:
RADIO   RADIO    RADIO 
RADIO   RADIO    RADIO 
RADIO   RADIO    RADIO 
SELECT     SELECT     TEXT INPUT
SELECT     SELECT     TEXT INPUT
SELECT     SELECT     TEXT INPUT

在下面的代码中，我使用了 .after 函数来跟随 Select 选项，但它仍然显示在上面

$('#condition' + num).after(newElem); // 在最后一个“可复制”输入字段之后插入新元素 $('#logical' + num1).after(newElem);

newElem1 插入到logicalxxx 项之后，也就是最后插入的条件项之前。如果你更换

           // insert the new element after the last "duplicatable" input field
            $('#condition' + num).after(newElem);
            // insert the new element after the last "duplicatable" input field
            $('#logical' + num1).after(newElem1);

和

  $('#condition' + num).after(newElem).after(newElem1);

newelem1 直接插入 newelem 之后，我认为这会产生预期的效果（更新的小提琴：http: //jsfiddle.net/ATzBA/2/）
