How to get multiple values from range slider - bootstrap-slider.js

Question

I am using bootstrap-slider.js - http://www.eyecon.ro/bootstrap-slider/ to give me range slider functionality. I have 9 sliders on one page and am getting the value only from the first slider.

How do I get the value for the other sliders?

<input type="text" class="sliderMaster slider-horizontal" id="sl9" name="q12" value="" data-slider-min="0" data-slider-max="100" data-slider-step="1" data-slider-value="50" data-slider-orientation="horizontal" data-slider-selection="after" data-slider-tooltip="show">


<input type="text" class="sliderMaster slider-horizontal" id="sl2" name="q2" data-slider-min="0" data-slider-max="100" data-slider-step="1" data-slider-value="50" data-slider-orientation="horizontal" data-slider-selection="after" data-slider-tooltip="show">


<input type="text" class="sliderMaster slider-horizontal" id="sl3" name="q3" data-slider-min="0" data-slider-max="100" data-slider-step="1" data-slider-value="50" data-slider-orientation="horizontal" data-slider-selection="after" data-slider-tooltip="show">

$(function(){
    $('#sl1').slider({
          formater: function(value) {
            return 'Current value: '+value;
          }
    });
    $('#sl2').slider({
          formater: function(value) {
            return 'Current value: '+value;
          }
    });
    $('#sl3').slider({
          formater: function(value) {
            return 'Current value: '+value;
          }
    });
 });

Answer 1

You can get the values like so:

console.log("Slider 1 = "+$("#sl1").data('slider').getValue());
console.log("Slider 2 = "+$("#sl2").data('slider').getValue());
console.log("Slider 3 = "+$("#sl3").data('slider').getValue());    

Fiddle here.

Edit

So to clarify - there does appear to be a problem that the slider is not actually updating the value of the underlying input. And when that input is posted via a form submit to the server, this causes a problem.

You could try adding an event to explicitly update the input when a slider changes, like so:

$(function(){
  $('#sl1').slider({
       formater: function(value) {
         return 'Current value: '+value;
       }
  }).on('slideStop', function(ev){
     $(this).val($(this).data('slider').getValue());
  });
  $('#sl2').slider({
        formater: function(value) {
          return 'Current value: '+value;
        }
  }).on('slideStop', function(ev){
     $(this).val($(this).data('slider').getValue());
  });
  $('#sl3').slider({
        formater: function(value) {
          return 'Current value: '+value;
        }
  }).on('slideStop', function(ev){
     $(this).val($(this).data('slider').getValue());
  });
});

and in each input set value to the same value as data-slider-value as this will be the default value i.e.

<input type="text" class="sliderMaster slider-horizontal" id="sl2" name="q2" data-slider-min="0" data-slider-max="100" data-slider-step="1" data-slider-value="50" value="50" data-slider-orientation="horizontal" data-slider-selection="after" data-slider-tooltip="show">
