Question

I have a button in html called btnS:

<button type="submit" id="btnS" class="hide" value="button">Send</button>

That I disabled with dom via external script dom:

btnS.setAttribute('disabled', 'false');

I tried to get it “back on” again via:

btnS.setAttribute('enabled', 'true');

But that didn’t work? The button was first invisible via a css rule:

.hide {
    visibility : hidden;
}

And I changed that as well before with :

btnS.setAttribute('class', 'show');     

Rule:

.show {     visibility:visible; }

Answer 1

There is only one attribute:

var btnS = document.getElementById("btnS");

// Disable
btnS.setAttribute('disabled', 'disabled');

// Enable
btnS.removeAttribute('disabled');
