The code runs through once, if at all. The console is silent. What's the problem?

The function hides the extra content under the spoiler automatically by adding a class and removing it when you click on the special div.

I tried using document ready, put in the bottom of the page, put in the beginning. In General, the script works on mood, it may, for example processing along the 10 sites on page 8, maybe all, maybe none.

$(function() {
 var posc = $(this);
 if (posc.height() > 1000) {
 posc.append('<div class="show-more-div">Expand</div>');


Checked for conflict with other scripts (removed everything else), but the error continues.

$(function(){}) calls the callback, after loading the document and building the DOM, but to download all other files (scripts, images, styles).
Try using $(window).on('load', function(){}).

All figured out. Forgot $(window).load(function() {
