使用鼠标上下更改值时的UI Spinner Bug [英] UI spinner bug when changing value using mouse up and down

问题描述

我将十进制微调器添加到了我的网站.

I added the decimal spinner to my site.

我的价值是56.20.当我改变使用鼠标滚轮时，我期望是57.20，但是现在显示为57:00.

My value was 56.20. When I change use mouse wheel up, I am expecting 57.20, but now it is showing 57:00.

该功能如下所示:

<script>
  $(function() {
    $( "#spinner" ).spinner({
      step: 1.00,
      numberFormat: "n"
    });

    $( "#culture" ).change(function() {
      var current = $( "#spinner" ).spinner( "value" );
      Globalize.culture( $(this).val() );
      $( "#spinner" ).spinner( "value", current );
    });
  });
  </script>

我也包括了演示

推荐答案

我完全不认为这是一个错误，只是简单地将其四舍五入-我认为这是 spinner.js ，该操作将汇总:

I don't think it's a bug at all sorry to say, it's simply rounding up - I think this the part in the jQuery code within the spinner.js that actions the round up:

在 _spin()期间:

value = this._adjustValue( value + step * this._increment( this.counter ) );

调用 _adjustValue():

_adjustValue: function( value ) {
    var base, aboveMin,
        options = this.options;

    // make sure we're at a valid step
    // - find out where we are relative to the base (min or 0)
    base = options.min !== null ? options.min : 0;
    aboveMin = value - base;

    // - round to the nearest step
    aboveMin = Math.round(aboveMin / options.step) * options.step;

    // - rounding is based on 0, so adjust back to our base
    value = base + aboveMin;

    // fix precision from bad JS floating point math
    value = parseFloat( value.toFixed( this._precision() ) );

    // clamp the value
    if ( options.max !== null && value > options.max) {
        return options.max;
    }
    if ( options.min !== null && value < options.min ) {
        return options.min;
    }

    return value;
},

来源:但是您可以尝试的是在旋转& ;;之前获取价值.然后在完成旋转后根据之前的以下两个回调事件重新调整值:

But what you could try, is catching the value before spinning & then re-adjusting the value after a completed spin, based on what you had before with the two callback events below:

var beforeSpin = 1.00;

$( "#spinner" ).spinner({
      step: 1.10,
      numberFormat: "n",
      start: function( event, ui ) {
          beforeSpin = ui.value;
      },
      //or stop: function(){}
      spin: function( event, ui ) {
          //Do some re-value
          //funciton based on old value
      }
});

那，或者根据您的需要重新编程 _adjustValue:function()-毕竟是开源的:)

That, or re-program the _adjustValue: function() to your needs - Open source after all :)
