javascript - Object doesn't support property or method 'slice' -

i'm newbie javascript/jquery world. have div several links , want collect url's .

then want extract href's last 9 characters (actually wish optimize , collect digits independently length @ end of each string).i tried extract them slice() method not work.

in console error

object doesn't support property or method 'slice'

can convert object string ? appreciated ! code following

$(document).ready(function(){    var $posts= $('a.entry_title').each(function(){     $(this).attr('href');   });    var posts1 = $posts[0].slice(-9);   var posts2 = $posts[1].slice(-9);    var posts = ["myurl"+ posts1,"myurl"+posts2]   $('#div1').load(posts[0] + " .shadow3");   $('#div2').load(posts[1] + " .shadow3");  }); </script> 

you see object doesn't support because $.each returns jquery object.

use .map() instead because returns array on slice work

var $posts= $('a.entry_title').map(function(){    return $(this).attr('href'); }); 

result

["link1", "link2", "link3"....] // sample 

if wish array of hrefs last 9 characters of each link can use map way

var $posts= $('a.entry_title').map(function(){    return $(this).attr('href').slice(-9); // or can own magic }); 

result this

["k1", "k2", "k3"....] // after slicing words
