$(document).ready(function() {
var divHeight,l=3;
$('.comment').each(function() {
var $this = $(this),divHeight;
var $content = $this.find(".text-content"),
lineHeight= $content.css('line-height');
divHeight= ((parseInt(l)+3)*parseInt(lineHeight))+"px";
if($content.hasClass("short-text")){
$content.css("height","auto");
}
else{
$content.addClass("short-text");
$content.css("overflow","hidden");
$content.css("height",divHeight);
$content.on("focus",function(){
$(this).attr('aria-hidden', 'false');
})

html='<p class="'+'para'+'"><a href="#" class="morelink morelinkStyle">' + 'more' + '</a></p></span>';
$this.append(html);
});
$(".morelink").click(function(){
var $this = $(this),
$elem=$this.parents().find(".text-content");
if ($elem.hasClass("short-text")) {
$elem.removeClass("short-text");
$this.html('less');
divHeight = $elem.height();
$elem.css("height","auto");
} else {
$elem.addClass("short-text");
$elem.on("focus",function(){
console.log($(this));
$(this).css("border","2px solid red");

Editing the height & overflow properties of the div will not hide the content from a screenreader. You need to use display:none in your short-text class. (Also, it is easier to write the class in your CSS and just use jquery to add/remove the class name).
A couple of months ago, I was tasked with solving the same problem of implementing "Read More" / "Read Less" links while maintaining WCAG 2.0 accessibility.
If you aren't opposed to using Bootstrap and jQuery, I have a pretty good solution. The bootstrap collapse
class makes it possible.
