Examples

JavaScript
nebula.bufferedWindowLoad(function(){
    //Do something at window load
});

Useful for inside dynamic imports that happen on DOM Ready and need a window load listener inside of them; the window load may happen before the import finished loading.

JavaScript
jQuery(function(){
    import('./modules/whatever.js').then(function(module){
        nebula.bufferedWindowLoad(function(){ //This may actually happen inside of the module file itself, but for demonstration purposes doing it all here 
            //Do something at window load
        });
    });
});

    No Hooks

    This function does not have any filters or actions available. Request one?
    JavaScript
    nebula.bufferedWindowLoad = function(callback){
        //If the window load event has already happened, run the callback immediately
        if ( document.readyState === 'complete' ){ //Note: "interactive" = DOM Ready, "complete" = Window Load
            return callback();
        }
    
        //If the window has not yet loaded, add an event listener to wait for it
        window.addEventListener('load', () => callback());
    };
    

    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.bufferedWindowLoad = function(callback){
        //Write your own code here, leave it blank, or return false.
    }


    For dynamically imported module function overrides:

    jQuery(window).on('load', function(){
        nebula.bufferedWindowLoad = function(callback){
            //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.bufferedWindowLoad === 'function' ){
            nebula.bufferedWindowLoad = function(callback){
                //Write your own code here, leave it blank, or return false.
            }
    	}
    });
