More info in popup

I’ve wrote my own function jQuery to do that :

$("#productCartFullcube div.sp_td a").each(function(){ 
	if($(this).html() == "more") // maybe a better way to do that
	{ 
		var lien = $(this).attr("href"); // I take the link

                // Event click on a
                $(this).click(function()
                { 
                        // gif wait                         
                        $("#dialog").html("<div style='width: 100%;text-align:center'><img src='wp-content/uploads/2017/02/77443320c6509d6b500e288695ee953502ecbd6d_m.gif' /></div>");
                        // load the content in popup
			$("#dialog").load( lien + " #spider_catalog_div", function() { jQuery("#back_to_spidercatalog_button").hide(); } );
                        $('#dialog').dialog("open");
                });
	} 
});
