在表单提交时发送多选选择的值

Question

In a form I have 2 <select multiple> elements. First one is filled with <option> itens in server-side.

I have then developed a JavaScript code to move itens from one to another. That's a basic multiselect feature.

Now I must send second select's values back to server when form is submitted. But it only sends itens that are selected. That's not the behavior I need, I want all existing itens to be sent. Any idea how to implement it, preferably without using Ajax?

Answer 1

I ended up not implementing it. But if I would I'd just try to get all select's values into an array, JSON marshal them and put the string into the input hidden. I'd try to do it in form's submit event.
