问题描述

我正在使用 jQuery bootstrap ClockPicker ，并且只需要获取其分钟数可被5整除的时间例如，如果用户选择13:08，则ClockPicker应该选择13:05.

I am using jQuery bootstrap ClockPicker and need to get only times that their minutes are divisible by 5. For example if user selects 13:08, the ClockPicker should select 13:05.

是否有一种方法可以覆盖时钟选择器以舍入选定的分钟数?

Is there a way to override clockpicker to round down selected times minutes?

推荐答案

我没有找到使用 API .所以我用afterDone回调写了一个.

I didn't found a way to do this with the API. So I wrote one using afterDone callback.

我解析输入值并进行更改以获取新的分钟值.

I parse the input's value and make the change to get the new minutes value.

var clockpicker = $('.clockpicker').clockpicker({
  afterDone: function() {
    clockpicker.val(round());
  }
}).find('input');

function round() {
  var time = clockpicker.val(),
      arr = time.split(':'),
      hour = arr[0],
      min = arr[1],
      newMin = (Math.floor(parseInt(min) / 5)) * 5;

  return hour + ':' + (newMin > 9 ? '' : '0') + newMin;
}
