jQuery toggle and changing text

Question

jQuery

$('#message div').hide();
    $('.readmore').click(function(e){
        e.preventDefault();
        $('#message div').slideToggle();
    });

html

<div id="message">
    <p class="intro">This is an introduction.</p>
            <div>
            <p>This is the first paragraph thats orginally hidden</p>
        <p>This is the second paragraph</p>
            </div>
            <a href="#" class="readmore">Read More</a>
        </div><!--message-->

When the read more button is clicked the content is slideToggled and shows to everyone and clicked again it hides to only show my .intro but I would like to toggle the Read More text between Read More and Show Less.

How is this possible whilst using slideToggle

Answer 1

Check the text of current element inside its click event and use condition, see if you have to change the text if yes, change it using text() again ;).

Try this:

 $('.readmore').click(function(e){
    e.preventDefault();
    $('#message div').slideToggle();
    $(this).text( $(this).text() == 'Read More' ? "Show Less" : "Read More"); // using ternary operator.
});
