DropDownChoice检票口获得价值 [英] DropDownChoice wicket get value

问题描述

所以我在Wicket中有我的DropDownChoice:

so I have my DropDownChoice in Wicket:

final DropDownChoice drop_down_status = new DropDownChoice<String>("status", new PropertyModel<String>(this,"selected_status"), STATUS_LIST);

     form.add(drop_down_status);

如何获取所选值?我必须在按下另一个按钮后得到它，并从中准备sql语句.

How to get the selected value? I have to get it after another button is pressed and prepare sql statement from it.

drop_down_status.getRawInput()和drop_down_status.getInput()返回null(至少在我的情况下).

drop_down_status.getRawInput() and drop_down_status.getInput() return null ( at least in my case).

欢呼

推荐答案

Wicket会即时"更新"selected_status"值.

Wicket updates "selected_status" value "on the fly".

new PropertyModel<String>(this,"selected_status")

因此足以从模型值中获取价值:)

so its enough to get value from Model value :)
