How do I refresh the page on click if an element has exact text?

I have a link that says 'Add to Favorites'. By default when you click this link and you are logged in, you get diverted to a confirmation page to say your favorite has been added. If you are not logged in it takes you to a login screen.

If you have already added that item to your favorites the text says 'Remove from Favorites' with an updated link to include '?A=Remove'. If you click it, you are redirected to a page confirming the favorite removal.

Now what I want to do is this:

If you're not logged in get an alert message.

If you are logged in - Refresh the page (Ideally I'd like to change 'Add to favorites' to 'Favorite added successfully' instead of refreshing the page - but I don't know how).

If you have already added to the favorites - Refresh the page (Ideally I'd like to change 'Remove from Favorites' to 'Favorite removed successfully' instead of refreshing the page - but I don't know how).

The {module_isloggedin} tag is generated by the system I am using. It generates a '1' if logged in & '0' if not logged in.

So far all that happens is the error message - Perhaps because my :contains isn't working?

The whole code seems much too long and sloppy. I'm still learning :)

This is my jQuery so far, I haven't put in a page refresh for the 'remove from favorites' yet.

if(jQuery('.add-favourites').size() === 0){ return; }
 
     jQuery('.add-favourites a').live('click', function(e){   
 
         e.preventDefault();
         var loggedin = "{module_isloggedin}";
 
         if  (loggedin == 1) {
             if (jQuery('.box-content ul li:contains("Add to Favorites")').length > 0) {
                 document.location.reload(true);
             }else{
                 if(jQuery(this).attr('href').indexOf("A=Remove") != -1){
                     jQuery.ajax({
                         url: jQuery(this).attr('href'),
                         cache: false
                     });
                 }else{
                     jQuery.ajax({
                         url: jQuery(this).attr('href')+"&A=Remove",
                         cache: false
                     });
                 }
     }
     }else{
         alert('You must be logged in to add favorites.');
     }
 });
