The JQuery settings checkbox Select Radio is read-only, and by testing the text and textarea that use HTML tags, the button can set the readonly= "ReadOnly" property.
However, the checkbox, select, radio three controls cannot be used with the readonly= "ReadOnly" property, only disabled= "disabled" can be used.
So there's a problem. Also want to not let the changes, and want to get the value in the background. If you use the Disabled property, but you find (string value = request.form["XX"];) value is empty.
Do not want to modify the background code, and finally in the discussion with Bogo, finally came up with the following method.
