三个div(left,mid,right)是用float属性并列显示在界面的。

我复制了class=content这个节，如果我用eq（）指定改或删除我复制的节点的类名（eg.left,mid,right），竟然原来的节点的类名也会改变？要怎么让原来的不变呢？不知道是不是float这个属性造成的？请指教

我是这样操作节点的

                 $('.all').append( $('.content:eq(-1)').clone(true));


                 $(".all>.content:eq(-2)").children('.left').removeClass("left");
                 $(".all>.content:eq(-2)").children('.right').removeClass("right");
                 $(".all>.content:eq(-2)").children('.mid').removeClass("mid");
                 $(".right").html("");
                 $(".left").html("");
                 $(".mid").html("");

我最终要实现的效果是，服务器获取的数据（each（）遍历获得的）要写入到不同的div里面，所以想着改变我不需要写入的div的属性，就不会写入了，不知道思路对了没？

回复讨论(解决方案)

那是你找到的是所有的，可能并没有指向它或它的结点、你的方法并没有错

思路不是很明确，你可以换另一种逻辑来处理
