javascript - jQuery not returning jquery.closest().text() -


i'm having issue jquery returning text closest td.index. heres i'm working with:

$(document).ready(function() {     $.getjson("http://ddragon.leagueoflegends.com/cdn/4.14.2/data/en_us/rune.json", function(response){         console.log(response.data);         $.each(response.data, function (index, entry) {             $('table.runes').append('<tr><td class="index">'                     +index+ '</td><td class="icon"> \                     <div style="width:48px;height:48px;background:url(./assets/runes/rune0.png) -' +entry.image.x+ 'px -' +entry.image.y+ 'px no-repeat"> \                     </div></td><td class="entry-name">'                     +entry.name+ '</td></tr> \                     <tr><td></td><td class="entry-desc">'                     +entry.description+ '</td></tr>'                 );         });     });     jquery("body").on("click", "td.entry-name", function() {         var gettext = $(this).closest('td.index');         alert(gettext.text());     }); });

as can see table generated using json/jquery, , there td class name index holds id number each row.

when clicking on td.entry-name should closest td.index , return text inside it, id number, alert. reason doesn't work.

i wondered if looking @ code if see issue.

because td.index sibling of td.entry-name not ancenstor use .siblings() instead of .closest()

jquery("body").on("click", "td.entry-name", function() {     var gettext = $(this).siblings('td.index');     alert(gettext.text()); });
