javascript - Slider value addition picks up previous value -


i have made 2 sliders add 2 numbers , outputs in box.

my problem total box picks previous value of sliders.

example: both sliders valued @ 2. total comes out 3. console.log proved value output previous value(before slide).

i appreciate help, thanks.

here's code snippet demonstrate:

$(document).ready(function() {      $('#slider1').slider({      value: 1,      min: 1,      max: 5,      step: 1,      slide: function(event, ui) {        $("#one").val(ui.value);        $("#equals").val(add());      }    });      $('#slider2').slider({      value: 1,      min: 1,      max: 5,      step: 1,      slide: function(event, ui) {        $("#two").val(ui.value);        $("#equals").val(add());      }    });      function add() {      = $('#slider1').slider('value');      b = $('#slider2').slider('value');      total = + b;      return total;    }    });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <script src="http://code.jquery.com/ui/1.12.0/jquery-ui.js"></script>  <link href="http://code.jquery.com/ui/1.12.0/themes/smoothness/jquery-ui.css" rel="stylesheet" />    <div id="slider1"></div>  <div id="slider2"></div>  <input type="text" id="one" name="one">  <input type="text" id="two" name="two">  <input type="text" id="equals" name="equals">

in add function can add values of inputs ids one , two total sum value

$(document).ready(function(){          $('#slider1').slider({          value: 1,          min: 1,          max: 5,          step: 1,          slide: function( event, ui ){              $("#one").val( ui.value );	              $("#equals").val( add() );          }      });          $('#slider2').slider({          value: 1,          min: 1,          max: 5,          step: 1,          slide: function( event, ui ){              $("#two").val( ui.value );	              $("#equals").val( add() );          }      });          function add(){          = $('#one').val();          b = $('#two').val();          if(a) = parseint(a);          if(b) b = parseint(b);          total = + b;          return total;      }    });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <script src="http://code.jquery.com/ui/1.12.0/jquery-ui.js"></script>  <link href="http://code.jquery.com/ui/1.12.0/themes/smoothness/jquery-ui.css" rel="stylesheet" />    <div id="slider1"></div>  <div id="slider2"></div>  <input type="text" id="one" name="one">  <input type="text" id="two" name="two">  <input type="text" id="equals" name="equals">
