使用libLink的noUiSlider自定义格式化时间 [英] noUiSlider custom formatting time with libLink

问题描述

自定义格式加上noUiSlider中的时间值的libLink对我不起作用.

Custom formatting plus libLink of a time value in noUiSlider does not work for me as expected.

我想使用滑块以24小时格式(例如17:32)输出时间.

I want to use the slider to output a time in 24 hours format (like 17:32).

我还想输入一个有效时间，并通过libLink更新滑块.

I also want to enter a valid time and have the slider updated via libLink.

当我移动滑块时，输入中的时间会正确更新.但这不是相反的方法:在输入中输入新的时间，然后再进行散焦，将输入重置为先前的值.

When I move the slider, the time in the input is correctly updated. But it does not work the other way around: entering a new time in the input and then unfocusing resets the input to the previous value.

如果取消注释console.log函数HHMMtoMinutes()，则可以看到它触发了两次.这是怎么回事?

If you uncomment the console.log in function HHMMtoMinutes() you can see it firing twice. What is happening here?

$(document).ready(function() {

  $(".slider").noUiSlider({
    start: ["07:30"],
    range: {
      'min': 0,
      'max': 24 * 60
    },
    format: {
      to: minutesToHHMM,
      from: HHMMtoMinutes
    }
  });

  $(".slider").Link("lower").to($("#time"));

});

function minutesToHHMM(value) {
  value = Math.round(value);
  var hour = Math.floor(value / 60);
  var min = value - hour * 60;
  //console.log("value:" + value + "\thour: " + hour + "\tmin: " + min)
  return ("0" + hour).slice(-2) + ":" + ("0" + min).slice(-2);
}

function HHMMtoMinutes(value) {
  var split = value.toString().split(":");
  var hour = parseInt(split[0]) * 60;
  var min = parseInt(split[1]);
  //console.log("value: " + value + "\thour: " + hour + "\tmin " + min);
  return hour + min;
}

推荐答案

它运行两次，因为libLink

It runs twice because libLink needs to use the slider .val() method to update. Setting the formatting on the link solves your issue.

$(".slider").noUiSlider({
    start: [ 0 ],
    range: {
        'min': 0,
        'max': 24 * 60
    }      
});

$(".slider").Link("lower").to($("#time"), null, {
    to: minutesToHHMM,
    from: HHMMtoMinutes
});
