How to disable html button using JSTL tags

Question

I want disable HTML button depending on value present in Spring bean.I am using JSTL empty property but no luck.
Here is my code

   <input type="submit" value="SendEmail" disabled="${empty reportNotificationFbo.providersList}" >  

Here reportNotificationFbo is spring bean and providersList is a list.

I want to disable Submit button if providersList is empty.

-Thanks.

Answer 1

State of the button is controlled by the presence of disabled attribute, not by its value. Try the following:

<input type="submit" value="SendEmail"
    "${(empty reportNotificationFbo.providersList) ? 'disabled' : ''}" >
