Jquery hide and show div
Question
Hi there not very proficient in coding. I have #content fading out and in when .background-button clicked. How do I get text on button to display hide content / show content?
Also I need to fade out another two divs (.button-next, .button-prev) when hide content clicked?
Anyone that can help?

I would add the event listener using registration instead of an inline event handler:
var button = document.querySelector('.background-button');
button.addEventListener("click", function(){
Show('content', this.children[0]);
return false;
});
The function Show would correspondingly have to be modified to:
function Show(elementid, link) {
ele = document.getElementById(elementid);
if (ele.style.display == 'none') {
ele.style.opacity = 0;
ele.style.filter = 'alpha(opacity=0)';
ele.style.display = '';
valueop = 1;
setTimeout("fadeIn()", openingdelay);
}
else {
valueop = 9;
setTimeout("fadeOut()", closingdelay);
}
if(link.getAttribute('data-hidden') == "hidden"){
link.innerHTML = "Click Me To Hide Stuff";
link.removeAttribute("data-hidden");
}else{
link.innerHTML = "Click Me To Reveal More";
link.setAttribute("data-hidden", "hidden");
}
}

I modified your html to put and ID to the link: #show_more
HTML:
<div id="content" >Hello! This will remain hidden until the link is clicked.</div>
<div class="background-button"><a id="show_more" href="#">Click Me To Reveal More</a></div>
<div style="background-color:#000; color:#FFF; position:absolute; right:0px; top:100px; height:50px; width:100px;" id="button-next">next</div>
<div style="background-color:#000; color:#FFF; position:absolute; right:0px; top:200px; height:50px; width:100px;" id="button-prev">prev</div>
jQuery:
$('#content, #button-next, #button-prev').hide();
$('#show_more').click(function(e) {
e.preventDefault(); // disable default <a> behavior
if ($('#content').is(':visible')) {
$('#show_more').text('Show Content');
} else {
$('#show_more').text('Hide Content');
}
$('#content, #button-next, #button-prev').fadeToggle();
});
The first line simply hides the content and buttons. You should hide them via CSS or inline styles and remove this line of code.
