If you go with @Rituparna’s solution, try this:
Don’t forget to add <a href="#" class="close">X</a>
in your container.
jQuery(function($){
$(".plink").on('click', function( event ){
event.preventDefault();
// cache the link clicked on
var link = $(event.target);
// use the link attr to target the desc
var containerID = link.attr('href');
// get the description contained in the link
var desc = link.find('.member-desc');
// send the member content to the container
$(containerID +' #desc_holder').html(desc);
});
// functionality for the close button
$('.close').on('click', function( event ) {
event.preventDefault();
$('#desc_holder').html('');
}
});
