How to Programmatically Disable HTML Buttons Using JavaScript?

Disabling HTML Buttons Dynamically with JavaScript

While disabling an HTML button by appending "disabled" directly to its tag is a common practice, it raises the question of how to achieve this programmatically using JavaScript. Contrary to popular belief, "disabled" is indeed an attribute, despite the lack of an associated value in its HTML code.

In JavaScript, the "disabled" property of an HTML button can be set to true or false to toggle its enabled/disabled state. This can be achieved using dot notation, as seen in the following example:

<code class="javascript">foo.disabled = true;</code>

Alternatively, the setAttribute() and removeAttribute() methods can also be used to manage the "disabled" attribute:

<code class="javascript">foo.setAttribute('disabled', 'disabled'); // Disable button
foo.removeAttribute("disabled"); // Enable button</code>

However, using these methods is not recommended when working with older versions of Internet Explorer, as they are known to exhibit bugs with setAttribute().
