Input fields marked with disabled="disabled"never send their value to the server when the form is posted. You could use the readonly="readonly"attribute in order to still make the field not editable by the user but send the initial value to the server when the form is submitted.
disabled="disabled"当表单发布时，标记为永远不会将其值发送到服务器的输入字段。您可以使用该readonly="readonly"属性使该字段仍不能被用户编辑，但在提交表单时将初始值发送到服务器。

You can't get disable property value into server side. You need to run javascript to fetch disabled value into servlet.
您无法在服务器端获取禁用属性值。您需要运行 javascript 才能将禁用的值提取到 servlet 中。
