How Can I Control Element Visibility in jQuery Beyond `.hide()` and `.show()`?

Achieving Element Visibility with jQuery: Beyond .hide() and .show()

The jQuery .hide() and .show() methods have become quintessential tools for manipulating element visibility based on CSS display settings. However, there may be scenarios where adjusting the display property is not sufficient or desired. To address this need, it is possible to create custom jQuery functions that target the visibility property.

Creating Custom Visibility Functions

To create custom functions that target visibility, we can leverage the .css() method. The following examples demonstrate how to define functions for hiding, showing, and toggling visibility:

jQuery.fn.visible = function() {
  return this.css('visibility', 'visible');
};

jQuery.fn.invisible = function() {
  return this.css('visibility', 'hidden');
};

jQuery.fn.visibilityToggle = function() {
  return this.css('visibility', function(i, visibility) {
    return (visibility == 'visible') ? 'hidden' : 'visible';
  });
};

Overloading the toggle() Function

If a more seamless integration with the existing toggle() function is preferred, it is possible to overload it to handle visibility:

!(function($) {
  var toggle = $.fn.toggle;
  $.fn.toggle = function() {
    var args = $.makeArray(arguments),
      lastArg = args.pop();

    if (lastArg == 'visibility') {
      return this.visibilityToggle();
    }

    return toggle.apply(this, arguments);
  };
})(jQuery);

With these custom functions or overloading techniques, you can now effortlessly manage element visibility using the familiar jQuery syntax without resorting to CSS display settings.
