readonly on numberbox not work

[Opan Mustopah]

hello again,

why readonly not working on numberbox plugins?
i already set readonly options to true, but users still can edited.

because if i disabled that element, the value won't sent to server when form is submitted.

many thanks for the answer

here is my code:

Code:

<input id="z_gw_estimate" class="easyui-numberbox m numberbox-f textbox-f" type="text" style="width: 100%; height: 30px; display: none;" data-options="precision: 1, readonly: true" textboxname="m_mvo_b_ship_a[z_gw_estimate]" numberboxname="m_mvo_b_ship_a[z_gw_estimate]">
