javascript - Why am I returned undefined? -


i wanting attribute of parent element cursor inside of.

i have been totally unsuccessful 2 hours now, i'm posting see if has suggestions. function have don't know why parentid returns undefined:

function getattrofparent() {     var newrange = rangy.getselection().getrangeat(0);     var parentelement = newrange.commonancestorcontainer;     var parentid = $(parentelement).attr('id');     alert(parentid); }

this works fine text of parent element...

function gettextofparent() {     var newrange = rangy.getselection().getrangeat(0);     var parentelement = newrange.commonancestorcontainer;     var parenttext = $(parentelement).text();     alert(parenttext); }

...and works fine title of specified element.

function getattrofelement() {     var parentid = $('#1').attr('id');     alert(parentid); }

here's jsfiddle, have click inside of text area first 2 functions work.

parentelement = newrange.commonancestorcontainer isn't giving parent element, giving parent node.

this obvious if console.log(parentelement) see being selected.

if select text entirely inside 1 of spans (which have ids) text node (which doesn't have id).

if select more text, paragraph element node (which doesn't have id).

you might want try var parentelement = $(newrange.commonancestorcontainer).parents('span');
