temporaryClass()

Temporarily change an elements class for a period of time and then revert back to the original class.

JavaScript February 7, 2021

Usage

JavaScript
nebula.temporaryClass(element, activeClass, inactiveClass, period)

Parameters

element
(Required) (Object or String) The element whose class will be changed
Default: None

activeClass
(Required) (String) The class to use during the active period
Default: None

inactiveClass
(Optional) (String) The class to change to after the active period has elapsed
Default: ""

period
(Optional) (Integer) How long the active class should be shown (in milliseconds)
Default: 1500

Parameter Notes

If an inactiveClass is not provided, Nebula will attempt to parse the classes for a Font Awesome class, otherwise it will default to an empty string.

Examples

Change an icon to a check and then after 5 seconds change it to a bomb.

JavaScript
nebula.temporaryClass(jQuery('i.example'), 'fa-check', 'fa-bomb', 5000)

Find the icon within a button and change it to a check. This attempts to revert back to whatever Font Awesome icon class was on the original icon before it was changed.

JavaScript
jQuery('a#activate').on('click', function(){
    nebula.temporaryClass(jQuery(this).find('i'), 'fa-check');
});

Temporarily add a class and then remove that class after (no inactiveClass)

JavaScript
nebula.temporaryClass(jQuery('.drop-area'), 'rejected');

Additional Notes

During the active period, a temporary-status-active class is added to the element. This can be used for additional styling or animation.

                }
            }
    
            $element.removeClass(inactiveClass).addClass(activeClass + ' temporary-status-active'); //Remove the inactive class and add the active class
            setTimeout(function(){
                $element.removeClass(activeClass + ' temporary-status-active').addClass(inactiveClass); //After the period of time, revert back to the inactive class

    Override

    To override or disable this JavaScript function, simply redeclare it with the exact same function name. Remember: Some functionality is conditionally loaded via dynamic imports, so if your function is not overriding properly, try listening for a DOM event (described below).

    JavaScript

    For non-module import functions:

    nebula.temporaryClass = function(element, activeClass, inactiveClass, period){
        //Write your own code here, leave it blank, or return false.
    }


    For dynamically imported module function overrides:

    jQuery(window).on('load', function(){
        nebula.temporaryClass = function(element, activeClass, inactiveClass, period){
            //Write your own code here, leave it blank, or return false.
        }
    });


    Custom Nebula DOM events do also exist, so you could also try the following if the Window Load listener does not work:

    jQuery(document).on('nebula_module_loaded', function(module){
        //Note that the module variable is also available to know which module specifically was imported
        if ( typeof nebula.temporaryClass === 'function' ){
            nebula.temporaryClass = function(element, activeClass, inactiveClass, period){
                //Write your own code here, leave it blank, or return false.
            }
    	}
    });
