JavaScript
nebula.scrollToListeners = function(){
if ( nebula.dom.html.css('scroll-behavior') !== 'smooth' ){ //If the html has smooth scroll-behavior, use that instead of this
//An href starts with a hash ID but is not only a hash ("#content" but not "#"). Do not use *="#" to prevent conflicts with other libraries who are linking to separate pages with an anchor on the destination.
nebula.dom.document.on('click keyup', 'a[href^="#"]:not([href="#"])', function(e){
if ( e.type === 'click' || (e.type === 'keyup' && (e.key === ' ' || e.key === 'Enter')) ){ //Spacebar or Enter
let avoid = '.no-scroll, .mm-menu, .carousel, .tab-content, .modal, [data-bs-toggle], #wpadminbar, #query-monitor';
if ( !jQuery(this).is(avoid) && !jQuery(this).parents(avoid).length ){
if ( location.pathname.replace(/^\//, '') === this.pathname.replace(/^\//, '') && location.hostname === this.hostname ){ //Ensure the link does not have a protocol and is internal
let thisHash = this.hash; //Defined here because scope of "this" changes later
let scrollElement = jQuery.find(thisHash) || jQuery('[name=' + thisHash.slice(1) +']'); //Determine the target
if ( scrollElement.length ){ //If target exists
let pOffset = ( jQuery(this).attr('data-offset') )? parseFloat(jQuery(this).attr('data-offset')) : nebula.scroll.offset; //Determine the offset
let speed = nebula.scroll.speed || 500;
nebula.scrollTo(scrollElement, pOffset, speed, false, function(){
history.replaceState({}, '', thisHash); //Add the hash to the URL so it can be refreshed, copied, links, etc. ReplaceState does this without affecting the back button.
});
return false;
}
}
}
}
});
}
//Using the nebula-scrollto class with data-scrollto attribute
//Note: Unlike the above click listener, this method ignores the browser "smooth scroll" setting and always handles the scroll
nebula.dom.document.on('click keyup', '.nebula-scrollto', function(e){
if ( e.type === 'click' || (e.type === 'keyup' && (e.key === ' ' || e.key === 'Enter')) ){ //Spacebar or Enter
let pOffset = ( jQuery(this).attr('data-offset') )? parseFloat(jQuery(this).attr('data-offset')) : nebula.scroll.offset;
if ( jQuery(this).attr('data-scrollto') ){
let scrollElement = jQuery.find(jQuery(this).attr('data-scrollto'));
if ( scrollElement !== '' ){
let scrollSpeed = nebula.scroll.speed || 500;
nebula.scrollTo(scrollElement, pOffset, scrollSpeed);
}
}
return false;
}
});
};
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.scrollToListeners = function(){
//Write your own code here, leave it blank, or return false.
}
For dynamically imported module function overrides:
jQuery(window).on('load', function(){
nebula.scrollToListeners = function(){
//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.scrollToListeners === 'function' ){
nebula.scrollToListeners = function(){
//Write your own code here, leave it blank, or return false.
}
}
});
