I'm in need of executing $(window).on('load', function() only if a certain class exists in a DOM element (div).
My current code is as follows:
jQuery(document).ready(function($) {
if (window.innerWidth > 767) {
var $sticky = $('#sticky');
var $stickyrStopper = $('.footer');
if (!!$sticky.offset()) { // make sure ".sticky" element exists
var generalSidebarHeight = $sticky.innerHeight();
var stickyTop = $sticky.offset().top;
var stickOffset = 0;
var stickyStopperPosition = $stickyrStopper.offset().top;
var stopPoint = stickyStopperPosition - generalSidebarHeight - stickOffset;
var diff = stopPoint + stickOffset;
$(window).scroll(function(){ // scroll event
var windowTop = $(window).scrollTop(); // returns number
//////////////
if (stopPoint < windowTop) {
$sticky.css({ position: 'absolute', top: diff });
} else if (stickyTop < windowTop+stickOffset) {
$sticky.css({ position: 'fixed', top: stickOffset });
} else {
$sticky.css({position: 'absolute', top: 'initial'});
}/////////////
});
}
}
});
And this is my idea, if the class exists:
jQuery(document).ready(function($) {
if (window.innerWidth > 767) {
if ($(".classexists")[0]){
Where the element would be:
<div class="classexists">123</div>
Execute window on load function before the main function:
$(window).on('load', function() {
if class does not exist, do not actually execute a $(window).on('load', function() {, just execute the rest of the code normally.
This code is supposed to create a sticky sidebar.
If i'm understanding your problem correctly, try this:
function example() {
var $sticky = jQuery('#sticky');
var $stickyrStopper = jQuery('.footer');
if (!!$sticky.offset()) { // make sure ".sticky" element exists
var generalSidebarHeight = $sticky.innerHeight();
var stickyTop = $sticky.offset().top;
var stickOffset = 0;
var stickyStopperPosition = $stickyrStopper.offset().top;
var stopPoint = stickyStopperPosition - generalSidebarHeight - stickOffset;
var diff = stopPoint + stickOffset;
jQuery(window).scroll(function () { // scroll event
var windowTop = jQuery(window).scrollTop(); // returns number
//////////////
if (stopPoint < windowTop) {
$sticky.css({ position: 'absolute', top: diff });
} else if (stickyTop < windowTop + stickOffset) {
$sticky.css({ position: 'fixed', top: stickOffset });
} else {
$sticky.css({ position: 'absolute', top: 'initial' });
}/////////////
});
}
}
if (window.innerWidth > 767) {
if (jQuery('.classexists').length > 0) {
jQuery(window).on('load', function () {
example();
});
} else {
example();
}
}
