js script

$(".favdelparentfold ul li .trashcan").click(function() {   if ($(this).parent().find('ul').length || $(this).closest('.favdelsubfold').length <1 ) return;    var tr = $(this).prev('a').text();   var pa = $(this).closest('.favdelparentfold').find('#pfdel').text();   var ya = $(this).parent('#sfdocdel').text();   alert(tr);   alert(pa);   alert(ya); });

working code:

https://jsfiddle.net/atg5m6ym/409/

you cannot have duplicate ids on page. invalid html , browser can access first match. use class id=pfdel values (and else has ids not unique per element).

a few lines of code changes use class selector pfdel etc:

  var tr = $(this).prev('a').text();   var ya = $(this).closest('.favdelsubfold').find('.sfdel').text();   var pa = $(this).closest('.favdelparentfold').find('.pfdel').text();
