Implementing a "read more" feature in jQuery to toggle the display of HTML content

I need help implementing a read more feature in jquery that will allow me to cut off content and reveal the remainder with the click of a button.

If the content is simple text, I could easily wrap the hidden portion in a span. However, the content may contain HTML as well.

For instance:

<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea --CUT OFF HERE-- commodo consequat. Duis aute irure dolor in reprehenderit</p>
<p> voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>

In this example, I want to cut off the content at the marker "--CUT OFF HERE--" within the first paragraph. The marker may not always be inside a paragraph tag or there may not be any other HTML elements present. I need a solution that can handle these variations.

What would be the best way to achieve this functionality using jQuery?

Presented here is a rather intricate solution. The main idea is to utilize the .html() function to append the initial part of the content to an HTML element and let jQuery handle the closing tags. Upon clicking the "read more" link, another instance of .html() is employed to populate the HTML element with the full string, excluding the section marked as "--CUT OFF HERE--".

var allContent = "<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea --CUT OFF HERE-- commodo consequat. Duis aute irure dolor in reprehenderit in</p><p> voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>",
    $container = $('#contentBox'),
    splitString = "--CUT OFF HERE--",
    arrayContent = allContent.split(splitString),
    firstPart = (arrayContent[0] === allContent) ? allContent : arrayContent[0]+"...",
    readMoreLink = "<a href='#'>Read more</a>";

$container.html(firstPart);

$(readMoreLink).on('click',function(e) {
    e.preventDefault();
    $(this).parent().html(arrayContent.join(''));
}).appendTo($container);

Unsure if this meets your needs, but check out the code snippet provided below:

<p>Press the button to reveal or conceal the text below <input id="button" type="button" value="Read More" /> </p> 

<p id="show_hide" style="display:none;">This text will appear and disappear upon clicking</p>

(function() { $('#button').click(function() { $('#show_hide').toggle(300); }) })(jQuery);

This is a standard process. Initially, I hid the 'show/hide' paragraph that should be visible when the user clicks on the button. The inline CSS was added solely for illustration purposes. It is advised by professionals to utilize an external CSS file for styling... I utilized the toggle() function within the click event handler to create the animation effect...

When working with HTML, it's important to always wrap your text within HTML tags for proper display. This can be done using various tags such as div, p, span, etc. For example, let's assume that the text is wrapped in a div tag with a classname of response_text.

<div class="response_text">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea --CUT OFF HERE-- commodo consequat. Duis aute irure dolor in reprehenderit in</div>

.show_me {
  display:none;
}

function makeToggle(ele){
  var html = $("." + ele).html();
  var textarray = html.split("--CUT OFF HERE--");
  var p = $("<p />").text(html).addClass("hide_me");
  var p1 = $("<p />").text(textarray[0]).addClass("show_me");
  var brn = $("<button />").click(function(){
    $(".hide_me").hide();
    $(".show_me").show();
  }).text("hide me").addClass("hide_me");
  var brn1 = $("<button />").click(function(){
    $(".show_me").hide();
    $(".hide_me").show();
  }).text("show more").addClass("show_me");
  $("." + ele).html("").append(p).append(p1).append(brn).append(brn1);
}
makeToggle("response_text");
