If you have requirement to open page in Popup Dialog instead of new page you can use following code. This look more professional and keep the user on same page. This is helpful in showing content like user details or payment records etc.

This will also helpful in case you want to have this functionality in multiple pages hence you just need to have .use-dialog class to the corresponding hyper link and code to open dialog is already there in theme js.

AUI().ready(
 function() {
     AUI().all('.use-dialog').on('click', function(event) {
         var url = event.currentTarget.get('href');
         var title = event.currentTarget.get('title');
         event.preventDefault();

       Liferay.Util.openWindow({
            dialog : {
                align : {
                    points : [ 'tc', 'tc' ]
               },
                width : '95%'
            },
            title : title,
            uri : url
        });
    });
