JavaScript control buttons are available or unavailable. javascript is unavailable.

The example in this article describes how JavaScript control buttons are available or unavailable. Share it with you for your reference. The details are as follows:

The following JS Code uses the disabled attribute of the button object to control whether the button is available.

<! DOCTYPE html> <body> <form> Buttons: <input type = "button" id = "firstbtn" value = "OK"> <input type = "button" id = "secondbtn" value = "OK"> </form> <p> Click the button below to disable the first button above. </p> <button onclick = "disableElement ()"> Disable button </button> <script> function disableElement () {document. getElementById ("firstbtn "). disabled = true ;}</script> </body>  

I hope this article will help you design javascript programs.
