How to Easily Disable and Enable Buttons and Links using jQuery and Bootstrap?

How to Effortlessly Disable/Enable Buttons and Links with jQuery Bootstrap

Understanding the Issue

Sometimes, you may encounter situations where you want to prevent users from interacting with certain buttons or links. This involves both visually indicating their disabled state and preventing any click events.

Solution for Buttons

Disable buttons seamlessly by manipulating their disabled property:

<input type="submit" class="btn" value="My Input Submit" disabled/>
<input type="button" class="btn" value="My Input Button" disabled/>
<button class="btn" disabled>My Button</button>

For a custom jQuery disable function:

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

Disable: $('input[type="submit"], input[type="button"], button').disable(true);
Enable: $('input[type="submit"], input[type="button"], button').disable(false);

Solution for Anchor Tags (Links)

Anchor tags do not have a disabled property, but Bootstrap handles this with CSS styling. Additionally, we can incorporate jQuery to prevent links from functioning when disabled:

.btn.disabled, .btn[disabled] {
    cursor: default;
    opacity: 0.65;
    color: #333;
    background-color: #E6E6E6;
}

<a href="http://example.com" class="btn">My Link</a>

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

Disable: $('a').disable(true);
Enable: $('a').disable(false);

Combined Solution

Combining the above approaches, we can extend the disable function to check element type and handle disabling accordingly:

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);
        });
    }
});

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