Jquery result from sum of array incorrect -

var answ = [];  $(document).ready(function() { $("#result").click(function() { answ = []; $('input[type="radio"]:checked').each(function(){  answ.push($(this).val());  //push values in array }); var total = 0; (var = 0; < answ.length; i++) { total += answ[i] << 0; } console.log(total); }); });  $("#shlong").click(function() { console.log(answ); });    fb.ui(  {   method: 'feed',   name: 'facebook dialogs',   link: 'http://developers.facebook.com/docs/reference/dialogs/',   picture: 'http://fbrell.com/f8.jpg',   caption: total,   description: 'dialogs provide simple, consistent interface                     applications interface users.',      message: 'facebook dialogs easy!'    },   <input type="radio"  name="quiz1" value="1">  <input type="radio"  name="quiz2" value="4">  <input type="radio"  name="quiz3" value="1">  <button id="result">penis</button>  <input type="button" onclick="share_prompt()" value="share" /> 

hello all, trying have results code @ top ($total) display in fb.ui displays entire array like: ["1"], ["4"], ["1"] how make output console.log single number

instead of debbuging messy un-indented code, i'm gonna offer simpler approach. first, question asked myself , couldn't find answer..

why storing every value in array??

ok, it's out of system now.. let's avoid using useless array of yours , things done quickly..

my suggestion add each value total while loop.. this:

$(document).ready(function () {     $("#result").click(function () {         var total = 0;          $('input[type="radio"]:checked').each(function () {             total += this.value << 0;         });          alert(total);     }); }); 

edit: in order have best answer, here working jsfiddle
