How Can I Disable and Enable Buttons and Links Using jQuery and Bootstrap?

Disabling and Enabling Buttons and Links Using jQuery and Bootstrap

Sometimes you need to prevent specific buttons or links from being clicked and give them a disabled appearance. Here's how to achieve this using jQuery and Bootstrap:

Buttons

Buttons in HTML have a built-in "disabled" attribute, making it easy to disable them:

<button class="btn" disabled>Disabled Button</button>

To disable buttons with a custom jQuery function, extend their functionality with disable() method:

jQuery.fn.extend({
    disable: function(state) {
        return this.each(function() {
            this.disabled = state;
        });
    }
});

$('button').disable(true); // Disable buttons
$('button').disable(false); // Enable buttons

Anchor Tags

Disabled isn't a valid attribute for anchor tags (). Instead, Bootstrap styles elements with the .btn.disabled class to make them appear disabled.

<a href="#" class="btn disabled">Disabled Link</a>

To prevent links from functioning when disabled, use jQuery to intercept clicks:

$('body').on('click', 'a.disabled', function(event) {
    event.preventDefault();
});

Combined Approach

You can extend the disable() function to handle inputs, buttons, and links:

jQuery.fn.extend({
    disable: function(state) {
        return this.each(function() {
            var $this = $(this);
            if($this.is('input, button, textarea, select'))
                this.disabled = state;
            else
                $this.toggleClass('disabled', state);
        });
    }
});

This allows you to disable all clickable elements with a single line of code:

$('input, button, a').disable(true); // Disable all clickable elements
$('input, button, a').disable(false); // Enable all clickable elements
