JavaScript - Readmore.js - Method is not a function

I am attempting to implement readmore.js into my code but I am continuously running into readmore.js is not a function error. I've read over the documentation multiple times and I am unable to figure out what I am doing wrong. When implemented correctly should include a "READ MORE" button to expand the text in its entirety.
I've included the HTML script tag that is presented in the github
I've made sure I included a jquery cdn before the readmore.js
I've included a class name of article
I've attempted to wrap the .readmore in a function such as :
$(function () { $('.article').readmore({speed: 75, lessLink: 'Read less'});});
Here is a snippet of code that I am working with:
const data = [{ paragraph: "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis id aliquam nibh. Aenean a porttitor ipsum. Vestibulum ut sagittis dui, nec pharetra eros. Vivamus tempus fringilla dictum. Maecenas facilisis auctor magna, a accumsan nunc molestie dictum. In tempus rhoncus condimentum. Aenean interdum leo et velit pellentesque dapibus. Vivamus nunc orci, commodo sit amet dui a, lobortis finibus arcu. Maecenas metus mauris, tincidunt sit amet ex id, gravida commodo nunc. Donec consequat tristique lacinia. Pellentesque commodo eu tortor sit amet rutrum. Vivamus mollis eros ipsum, in vestibulum lorem tempor sit amet. Morbi egestas orci sem, posuere rutrum augue malesuada eget. Mauris ultricies egestas luctus. Praesent at dignissim nunc. Aliquam erat volutpat."},{
paragraph: "Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Nullam porttitor tincidunt fringilla. In ullamcorper vitae sapien eget ornare. Nulla quis lacus condimentum lacus tincidunt consectetur ut in ante. Suspendisse a eleifend est. Pellentesque eu ornare magna. Vestibulum ac mi sit amet arcu tristique volutpat in id nisl. Aenean interdum et odio gravida hendrerit. Pellentesque at diam lacus. Mauris elementum ultricies imperdiet. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vivamus metus ligula, molestie at laoreet id, convallis et felis. Nullam molestie, augue vel interdum semper, dui massa feugiat risus, non sodales est massa non arcu. Vivamus ut sodales metus."
}
]
let htmlOutput = ""
for (let i = 0; i < data.length; i++) {
htmlOutput += "<div>" + data[i].paragraph + "</div>"
}
$("#report").html(htmlOutput)
$('.article').readmore({
speed: 75,
lessLink: 'Read less'
});
<div id="report" class="article">
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="/node_modules/readmore-js/readmore.min.js"></script>
My expected outcome is to be able to include the .readmore function and have a "read more" that will expand the text once clicked.

You will have to download the readmore.min.js file from the repo. The file is located here.
https://github.com/jedfoster/Readmore.js/blob/master/readmore.min.js
Then you can include it in your project by putting it in the same directory as your index.html file and add a script tag like this
<script src="readmore.min.js"></script>

hi this might have been solved but ill add my 2c.
from your code it seem that you are adding the text inside a nested div instead of the parent div with the article class.
try adding "id='report' class= 'article' " inside the for loop div and check if the plugin works

Javascript and Html; get page from URL

I am creating a website for a client and they have given me some very strict limitations. The html must be coded in one document (index.html), with the javascript and css each in their own separate document. They also want me to use Angular or Node only if necessary (it has not been necessary so far).
Since they are requiring multiple “pages” on the website, I am using Javascript to hide or unhide different divs corresponding to each page. I also have the separate divs internally referenced. Therefore, when the maps “page” is open the URL displays as https:\\site.com\#maps . When the page gets reloaded, it ignores the #maps and simply returns to the main “page”.
I have tried using window.location to get the url when the page is loaded, then pass that to my function; however, that has not worked. I also briefly tried messing with cookies to save the page location, but wasnt able to get very far with it.
How can I get the function to load the page I want based on the url?
function openPage(evt, PageName) {
// Declare all variables
var i, tabcontent, tablinks;
// Get all elements with class="tabcontent" and hide them
tabcontent = document.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
// Get all elements with class="tablinks" and remove the class "active"
tablinks = document.getElementsByClassName("tablinks");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
// Show the current tab, and add an "active" class to the link that opened the tab
document.getElementById(PageName).style.display = "block";
evt.currentTarget.className += " active";
//set the page cookie
var expiry = new Date();
expiry.setTime(expiry.getTime()+600000);
expires = "; expires=" + expiry.toUTCString();
document.cookie = "Page=" + PageName + expires + " ; path=/";
}

Well, each div element has to have the id attribute, this attribute identifies the page/div and will be set as value for the window.location.hash.
Than handle all click events which trigger the page change, for instance all a elements with href attribute set to these ids.
Then create function which will show/hide the desired page, and call this method when the whole html page is loaded.
Here is an example using jQuery (if you want there is no need to use jQuery, you can do it with vanilla javascript as well):
$(function() {
// Method wich show/hide pages
function showpage(target) {
// Target is the id of the page div
var $target = $(target);
// If there is not any page with that id do nothing
if(!$target.length) {
return;
}
// Hide all pages
$(".page").css("display", "none");
// Show the target page
$target.css("display", "block");
// Update the window has
window.location.hash = target;
}
// Handle clicks which show pages
$(document).on("click", "a[href^='#']", function (e) {
e.preventDefault();
showpage($(this).attr("href"));
});
showpage(window.location.hash);
});
.page {
display: none;
}

onmouseout event failed to fire and change value

I have a hover element in which when user hover over it will get text from a hidden element and when it hovers out it will reassign in its previous value.
My html is sort of like this.
<div id="product-name">Hover Here</div>
<br>
<div id="result-content">Lorem ipsum dolor sit amet.</div>
<div class="hidden">
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla pellentesque mi leo, ut cursus tellus tempor nec. Sed facilisis augue neque, a ornare urna ornare in. Etiam consequat, dui sit amet pretium bibendum, ante ipsum ullamcorper libero, vel tempus erat urna sed purus. Quisque id ultricies elit, non posuere nunc. Etiam pulvinar magna tortor, at aliquet turpis interdum et. Duis imperdiet enim ante, sit amet pretium enim aliquet venenatis. Donec ac nibh nibh. Interdum et malesuada fames ac ante ipsum primis in faucibus. Morbi aliquam est adipiscing volutpat pulvinar. Curabitur leo augue, iaculis id lacus sed, dictum vestibulum nulla. Etiam sit amet tempus felis, ac aliquet erat. Nunc ullamcorper consequat mattis. In molestie, tortor ac venenatis dapibus, eros neque vulputate nulla, in tristique ante diam non turpis. Maecenas mattis in risus eu ornare. Cras a rutrum nulla. Proin sagittis justo vehicula augue porttitor vulputate.
</div>
and javascript is this:
var object = document.getElementById("product-name");
object.onmouseover=function(){
document.getElementById("result-content").innerHTML = document.getElementsByClassName("hidden")[0].innerHTML;
};
object.onmouseout=function(){
document.getElementById("result-content")[0].innerHTML = document.getElementById("result-content").innerHTML;
};
jsfiddle.net
But my mouseout event failed me here. Can anyone help me out here how can i resolve this. I can't use jQuery in this dom only javascript, but I wouldn't mind if anybody show me a better approach to resolve javascript mouseout/mouseover paradigm.

Fiddle Demo
You need to store initial contents of the block.
var object = document.getElementById("product-name");
var currentHtml = document.getElementById("result-content").innerHTML;
object.onmouseover=function(){
document.getElementById("result-content").innerHTML = document.getElementsByClassName("hidden")[0].innerHTML;
this.onmouseout=function(){
document.getElementById("result-content").innerHTML = currentHtml;
}
};

document.getElementById("result-content")[0].innerHTML = document.getElementById("result-content").innerHTML; will take you nowhere. You have to preserve the value somewhere.
If you fancy a bit different approach then try this.
document.querySelector("#product-name").addEventListener("mouseover", function(){
var txt = document.querySelector("#result-content").innerHTML;
document.querySelector("#result-content").innerHTML = document.querySelector(".hidden").innerHTML;
this.addEventListener("mouseout", function(){
document.querySelector("#result-content").innerHTML = txt;
});
});
jsfiddle Demo
document.querySelector is supported in most browser.
http://caniuse.com/queryselector

I think, in this case must save somewhere previous state, like:
var object = document.getElementById("product-name"),
previous_state = document.getElementById("result-content").innerHTML;
Might not be the best approach, but without major changes in code should look like this:
jsfiddle

try this one for mouse out
object.onmouseout=function(){
document.getElementById("result-content").innerHTML ='Lorem ipsum dolor sit amet.';
};

Set height of certain div on click through jquery function in a-tag

I'd like to expand a certain story-div when a button inside the div is clicked.
i.e: An overview of reviews shows only the first few sentences of a review. When a button is clicked the review expands to full height.
<div id="overview">
<div class="story">
<div class="naam">John Doe</div>
<div class="plaats">Washington DC, USA</div>
<p>
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam at accumsan augue. Curabitur ac tortor felis. Quisque fringilla est at neque congue commodo. Proin metus libero, condimentum sed viverra et, pulvinar eget nisi. Donec viverra arcu ut ante adipiscing laoreet. In non tellus leo. Suspendisse ultrices eros quis odio fermentum id commodo ligula tempus. Nunc tincidunt suscipit dolor, nec tempus quam mattis non. Sed dapibus odio nec nisl ultricies vel commodo dolor sagittis.
</p>
<a class="readMore" href="javascript:openStory();" title="Read more">Read more ›</a>
</div>
<div class="story">
<div class="naam">John Doe</div>
<div class="plaats">Washington DC, USA</div>
<p>
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam at accumsan augue. Curabitur ac tortor felis. Quisque fringilla est at neque congue commodo. Proin metus libero, condimentum sed viverra et, pulvinar eget nisi. Donec viverra arcu ut ante adipiscing laoreet. In non tellus leo. Suspendisse ultrices eros quis odio fermentum id commodo ligula tempus. Nunc tincidunt suscipit dolor, nec tempus quam mattis non. Sed dapibus odio nec nisl ultricies vel commodo dolor sagittis.
</p>
<a class="readMore" href="javascript:openStory();" title="Read more">Read more ›</a>
</div>
</div>
.story has a fixed height of 120px. I'd like to set its height to 'auto' with the openStory(); function.
function openStory(){
this.parent('.story').css('height','auto');
}
Help is appreciated

$('.readMore').click(function(event) { // Bind click event to all .readMore elements
event.preventDefault(); // Prevent the default click action
$(this) // Refers to the clicked .readMore element
.parent() // Get parent element. Assuming it´s the .story element?
.css('height', 'auto'); // set CSS rule. But why not use a CSS class?
});
..and replace href="javascript:openStory();" with href="#".

Used this in the end to open/close the div:
$('.review .story a.readMore').click(function(){
animatingElement = $(this).parent('.story');
if(animatingElement.hasClass('open')){
animatingElement.removeClass('open');
} else {
animatingElement.addClass('open');
}
});
Until Stefan came up with the toggleClass-function
$('.review .story a.readMore').click(function(){
animatingElement = $(this).parent('.story');
animatingElement.toggleClass('open');
});
That's the way to go.

jQuery.. div reveal/slide?

I have a div, which has content in it.
The content could be really long, or the content could be really small.
I don't want the content to stretch the page on page load if it is long, I want them to click a "more" link and it will slide down and reveal the rest of the content.
For example:
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse vulputate mi egestas ligula feugiat volutpat. Morbi eros felis, aliquam in varius id, sodales quis nunc. Nulla sagittis consectetur arcu, sed auctor odio placerat quis. Praesent vitae lacus neque. Curabitur ultricies tristique sollicitudin. Suspendisse malesuada nunc at augue interdum at facilisis ipsum gravida.
Below it is a bar or link that says "show the rest"
Up on click, this div lengthens and shows the rest of the content:
Nunc congue sapien sed sem tincidunt ut adipiscing neque lacinia. Praesent facilisis quam sed tellus sodales id tristique massa ullamcorper. Donec sem turpis, cursus in elementum id, tincidunt a libero. Etiam feugiat, sem quis dictum imperdiet, nisl ante pharetra erat, ut ornare nulla justo ac sapien.
Lorem ipsum dolor sit amet,
consectetur adipiscing elit.
Suspendisse vulputate mi egestas
ligula feugiat volutpat. Morbi eros
felis, aliquam in varius id, sodales
quis nunc. Nulla sagittis consectetur
arcu, sed auctor odio placerat quis.
Praesent vitae lacus neque. Curabitur
ultricies tristique sollicitudin.
Suspendisse malesuada nunc at augue
interdum at facilisis ipsum gravida.
Nunc congue sapien sed sem tincidunt
ut adipiscing neque lacinia. Praesent
facilisis quam sed tellus sodales id
tristique massa ullamcorper. Donec sem
turpis, cursus in elementum id,
tincidunt a libero. Etiam feugiat, sem
quis dictum imperdiet, nisl ante
pharetra erat, ut ornare nulla justo
ac sapien.
I know itll be hard to control what will be cut off, blah blah but it isn't for that type of thing. The div does not contain text, it contains a list of features, for example X listing may have 4 features, Z listing may have 14 features, instead of the page stretching if the listing has 14 features listed vertically, we want it to only show a few and then they must click "show me more" for it to slide down and reveal the rest.
How would I go about doing this? Even a jsfiddle to demonstrate it?
Thank you :)

Try giving a fixed height to the div. You can use CSS for this. Then compare height of the list with the outer div. If it is greater show the bar with link show more. On click of this bar you can manage the height of outer div. Like this -
CSS
.parentDiv{
height:some fixed height px;
overflow: auto;
}
Jquery
var parentHeight = $('.parentDiv').height();
var listHeight = $('#List').outerHeight(true);
if(parentHeight < listHeight) {
$('#linkBar').show();
}
$('#linkBar').click(function(){
//$('.parentDiv').height(listHeight);
//OR you can use following code to animate the div
$('.parentDiv').animate({'height': listHeight}, 'slow')
});

Here's a working demo of my implementation (coincidentally similar to the answer given above; I was making this before any answers were given): http://jsfiddle.net/7fhrN/15/
It works for users without JavaScript and gives graceful degradation to your page. Try switching the JS library to something random on JsFiddle and click Run.
HTML:

Suspendisse malesuada nunc at augue interdum at facilisis ipsum gravida.</div>

CSS:
.stretchy
{
margin: 20px;
padding: 5px;
background-color: rgb(240, 240, 240);
overflow: hidden;
position: relative;
padding-bottom: 20px;
}
.inner
{
max-height: 120px;
overflow: hidden;
}
.reveal
{
position: absolute;
bottom: 0px;
}
JavaScript:
$(document).ready(function()
{
$('.stretchy').each(function()
{
if ($(this).height() > 130)
{
$(this).replaceWith('<div class="stretchy"><div class="inner">' + $(this).html() + '</div>Show me more lipsum</div>');
}
});
$('.reveal').toggle(function()
{
$(this).parent().find('.inner').animate({maxHeight: '1000px'});
}, function() {
$(this).parent().find('.inner').animate({maxHeight: '120px'});
});
});
Basically, I iterate over all the <div>s with the class stretchy. If they are too big, I replace them with a <div> with a container and a link at the bottom which changes the max-height of the inner <div> to some ridiculous value.
Just try it. Seeing > having me explain it to you.
