Hello All,

I am setting the value of a disabled text input form element with
JavaScript. How can I retrieve its value in Java?

request.getParameter(textInputID);

always seems to return 'null'.

I appreciate any effort to help me. Thank you for your time and
consideration.

Sincerely,

Sisilla

The 'disabled' attribute "[d]isables the input element when it first loads so
that the user can not write text in it, or select it."

So it is never entered into the request as a parameter.

Thus a server-side attempt to retrieve this value that was never entered into
the parameter list will always receive null. Because the parameter isn't
there. Because its input was disabled.

Thanks, Lew. I made the element read-only instead of disabled and used
css to give it the look of a disabled element. Thanks for your help.
