好的 - 所以我已经把头发拉出来太久了。希望各位大侠能帮帮忙。
我有一个表单，允许用户输入/编辑有关他们公司的数据。其中大部分是非常直接的表单字段编辑，但我有一部分允许用户选择他们的业务在什么状态下运行，然后将联系人分配给该状态。我正在使用 jQuery 和 2 个 listBox 控件，我允许用户双击他们想要操作的状态。jQuery 将所选状态移动到另一个 listBox 以及下拉控件，然后他们可以输入他们特定州的联系信息。
现在是“拔毛”部分。我已经看过很多关于从第二个 listBox 控件中获取数据，将其放入数组并将其放入隐藏表单字段的帖子 - 但是如何做到这一点的示例很少而且相差甚远。我发现我没有成功整合的少数几个。那里的任何帮助将不胜感激。
另一个难题是这个页面应该作为一个用户也可以编辑的页面 - 所以在初始加载时，我的页面应该（理想情况下）将用户已经通过 jQuery 选择的状态预加载到第二个列表框...但是进入第二个列表框的状态不应该出现在第一个列表框中。啊。任何关于如何实现这一点的指针也将不胜感激。
这是我的代码：

所以你有它。我知道，要消化的东西很多。我喜欢朝正确的方向踢。:)
