Extract the text of a disabled field

[enter image description here][1]

This is the HTML tag for the element. [1]: https://i.stack.imgur.com/8SjU8.jpg

I tried String A = Element.getText() to capture the value but it doesn't capture the text. I tried with

String A = element.getAttribute("value"); but still no text capture.

I tried with javascript executor also

String pageText = js.executeScript("return document.documentElement.innerText;",AdNum).toString();

This is also not capturing the text though it executes the script.
