如何禁用下拉列表中的默认选项

Question

我想禁用下拉列表中给出的默认选项。 例如下拉列表中有三个值

["Select a status", "Processing", "Completed"]

我想在“选择状态”上应用已禁用和已选择的属性。

你能告诉我怎么做吗？我无法在相同的值上使用这两个属性。

Answer 1

您是否尝试过使用options_for_select

<%= select_tag(:city_id, options_for_select(["Free", "Basic", "Advanced", "Super Platinum"], :disabled => "Super Platinum", :selected => "Super Platinum")) %>

Answer 2

以下为我工作

<%= select("post", "person_id", options_for_select(["Free", "Basic", "Advanced", "Super Platinum"], :disabled => "Super Platinum", :selected => "Super Platinum" ))  %>
