Button.disabled
From Opera 15 onward, Opera 11 & 12’s extension format is no longer supported, and instead, we’ve switched to Chromium’s extension model. Check out our new documentation for developing extensions for Opera 15 and higher and start building your own extensions.
Description
This property indicates if the Button
is disabled. By default, it is set to false
(meaning the button is enabled).
Example:
Create a button that gets disabled for a short while when clicked.
//
// The background process (e.g. index.html)
//
// Create a button
var button = opera.contexts.toolbar.createItem({
title: 'My Extension',
icon: 'icon.18x18.png',
onclick: disableButton // disable when clicked
});
// Add it to the browser UI
opera.contexts.toolbar.addItem(button);
function disableButton() {
// Disable the button
button.disabled = true;
setTimeout(function() {
button.disabled = false;
}, 500); // re-enable after timeout
}
