<ul style="text-[#01579b] space-y-1">
|
|
|
|
|
<li><strong>Enable:</strong> Uses <code>setAttribute('disabled', '')</code> to remove the disabled attribute</li>
|
|
|
|
|
<li><strong>Disable:</strong> Uses <code>setAttribute('disabled', 'true')</code> to add the disabled attribute</li>
|
|
|
|
|
<li><strong>Toggle:</strong> Uses <code>getAttribute('disabled')</code> to check current state, then toggles it</li>
|
|
|
|
|
<li><strong>Status:</strong> Uses <code>getAttribute()</code> to read multiple attributes and displays them</li>
|
|
|

|
<li><strong>Bonus:</strong> Also demonstrates setting custom data attributes and style changes</li>
