I want to add two variable开发者_StackOverflow社区s which have numeric values using javascript.

var seconds = 1100;
var time = 300;
 var newV = seconds + time;
   $('.show').html(newV);

But it is saying undefined

This HTML is probably what you were missing

<div class="show"> </div>

your code

$(document).ready(function() {
  var seconds = 1100;
  var time = 300;
  var newV = seconds + time;
  $('.show').html(newV);
});
