JQuery UI Slider - using default value in function

I need help with the jQuery UI slider, I have set an initial value, but I cannot find a way to display it on page load. I also need to be able to call both values ​​of the slider to execute the function and then display it on the screen.

You can have a look at my Fiddle test here> http://jsfiddle.net/cC3Qh/

JQuery

$(function() {
    $( "#slider1").slider({ 
        max: 2500,
        value: 1000,
        slide: function( event, ui ) { $( "#slider-result1" ).html( ui.value ); },
        change: function(event, ui) { calPrice(ui.value); }
    });

    $( "#slider2").slider({ 
        max: 30,
        value: 12,
        slide: function( event, ui ) { $( "#slider-result2" ).html( ui.value ); },
        change: function(event, ui) { calDays(ui.value); }
    });
  });

  function calDays(sliderval){
    var day = sliderval;
    day = day * 100;
    document.getElementById('price2').innerHTML = day;
    var price = document.getElementById('price1').innerHTML;
    price = price * day;
    document.getElementById('price3').innerHTML = price;
  }

  function calPrice(sliderval){
    var price = sliderval;
    price = price * 100;
    document.getElementById('price1').innerHTML = price;
  }

      

        
        
        
      

    

Thank.
