Question

I have some content that I am show/hiding using the Jquery toggle function.

I have prepended an arrow to each heading and would like to change the prepended arrow to a downwards arrow when the content is toggled.

Code so far:

$(document).ready(function(){
    $('.show-hide-list h3 a').prepend('> ');//Prepend arrow
    $('.show-hide-list li .show-hide-list-content').hide();//Hide content
    $('.show-hide-list h3').click(function() {//Perform toggle when clicked
        $(this).next('.show-hide-list-content').toggle();
        //Need to change orientation of prepended arrow when toggled
        return false;
    });
});

The html is as follows:

<ul class="show-hide-list">
<li>
       <h3><a href="#">Heading</a></h3>
   <div class="show-hide-list-content">
           Content to be toggled here.
       </div>
    </li>
 </ul>

How can I change the arrow orientation once toggled?

Wrap your arrow in a span tag so you can easily select it.

$(document).ready(function(){
    $('.show-hide-list h3 a').prepend('<span>&gt;&nbsp;</span>');//Prepend arrow
    $('.show-hide-list li .show-hide-list-content').hide();//Hide content
    $('.show-hide-list h3').click(function() {//Perform toggle when clicked
        $(this).next('.show-hide-list-content').toggle();
        var arrow = $(this).find('span');

        if (arrow.text().indexOf('V') >= 0) {
            arrow.html('&gt;&nbsp;');  
        } else {
            arrow.html('V&nbsp;');
        }
        //Need to change orientation of prepended arrow when toggled
        return false;
    });
}); ​
