Readonly select with jQuery

There's a control <select> on your page and you want to use it's value as selected and don't want to allow user to change it. Unfortunately, there's no attribute "readonly" for select as for <input> ones. You can use only attribute "disabled", but in this case its value will not be sent. But there's a trick how to do it.

First you should add attribute "disabled" and set it to "true". In this case after sending your form the value will not be sent to a server. But you can change the value of attribute before sending the form! You should just set the value of attribute "disabled" to false.

For example:

So, you should change attribute "disabled" value just before submitting.

For example, for SharePoint forms it you should override function OnPreSaveItem().
