jSlider jQuery插件:设置最小范围，并格式化最小值

Question

我使用jSlider来实现一个触摸友好的范围滑块，但我有两个问题:

1. 我想设置$10的最小范围，但我似乎无法做到这一点。(换句话说，下限和上限之间总是至少有10美元。)
2. 我不能得到最小的值格式正确为$0 -它显示$而不是$0(实际上我更喜欢它是$1，但我也不能实现)。

我已经设置了一个JSFiddle与我的滑块:http://jsfiddle.net/v3gUg/9/

这里也是代码，供参考:

var options = { 
  from: 0,
  to: 500,
  round: 10, 
  heterogeneity: ['50/100', '75/250'], 
  scale: ["£0", '|', "£50", '|' , "£100", '|', "£250", '|', "£500"],
  limits: true,
  step: 10,
  format: { format: '£#' }, // Doesn't return 0 correctly. 
  skin: "round_plastic",
  onstatechange: function() { 
      // Check range here and return false if too small?
      // But return false doesn't seem to do anything. 
     return false;
  }
};
jQuery("#price-slider").slider(options);

谁能提出解决这两个问题的方法?

EDIT:

       $(document).ready(function() { 
  var options = { 
      from: 0,
      to: 500,
      round: 10, 
      heterogeneity: ['50/100', '75/250'], 
      scale: ["$0", '|', "$50", '|' , "$100", '|', "$250", '|', "$500"],
      limits: true,
      step: 10,
      format: { format: '$#,' },
      skin: "round_plastic",
    callback: function() { 
      // if (range too small)
      //return false;
    },
  onstatechange: function( value ){
    var array = value.split(";");
    if(array[0] == array[1])
    {
      value = array[0]+";"+array[1];
      $(".holder").slider("value", p1, p2)
    }
  } 
    };
  jQuery("#price-slider").slider(options);
});
