A show-hide that still works (last used mid-2021); changes toggle content.
jQuery(function($) {
$(document).ready(function() { // this tells jquery to run the function below once the DOM is ready
var showText="Show"; // choose text for the show/hide link
var hideText="Hide";
$(".toggle").prev().append(' <a class="toggleLink" href="#">'+showText+'</a><span class="pointer">»</span>'); // append show/hide links to the element directly preceding the element with a class of "toggle"
$('.toggle').hide(); // hide all of the elements with a class of 'toggle'
$('a.toggleLink').click(function() { // capture clicks on the toggle links
if ($(this).text()==showText) { // change the link text depending on whether the element is shown or hidden
$(this).text(hideText);
} else {
$(this).text(showText);
}
$(this).parent().next('.toggle').toggle('fast'); // toggle the display
return false; // return false so any link destination is not followed
});
});
});
