--description--

You can also change the non-CSS properties of HTML elements with jQuery. For example, you can disable buttons.

When you disable a button, it will become grayed-out and can no longer be clicked.

jQuery has a function called .prop() that allows you to adjust the properties of elements.

Here's how you would disable all buttons:

$("button").prop("disabled", true);

Disable only the target1 button.

--hints--

Your target1 button should be disabled.

assert(
  $('#target1') &&
    $('#target1').prop('disabled') &&
    code.match(/["']disabled["'],( true|true)/g)
);

No other buttons should be disabled.

assert($('#target2') && !$('#target2').prop('disabled'));

You should only use jQuery to add these classes to the element.

assert(!code.match(/disabled[^<]*>/g));
