如何防止jQuery bootstrap ClockPicker获取不能被5整除的分钟数

Question

我正在使用 jQuery bootstrap ClockPicker 并且只需要获取他们的分钟可被 5 整除的时间。例如，如果用户 selects 13:08，ClockPicker 应该 select 13:05.

有没有办法覆盖 clockpicker 以向下舍入 selected 时间分钟？

Answer 1

我没有找到使用 API 执行此操作的方法。所以我写了一个使用 afterDone 回调。

我解析输入的值并进行更改以获得新的分钟值。

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;
}

如果您不介意对 Clockpicker 进行更改（我必须为 IE 进行更改），请在 bootstrap-clockpicker.js 中添加一个非官方选项，例如 "roundmodfive":
1. 改变这个

// Hours and minutes are selected
ClockPicker.prototype.done = function() {
    raiseCallback(this.options.beforeDone);
    this.hide();
    var last = this.input.prop('value'),
        value = leadingZero(this.hours) + ':' + leadingZero(this.minutes);
    if  (this.options.twelvehour) {
        value = value + this.amOrPm;
    }
...

2。通过这个

// Hours and minutes are selected
ClockPicker.prototype.done = function() {
    raiseCallback(this.options.beforeDone);
    this.hide();

    var last = this.input.prop('value');
    //Unofficial option added
    /*
        Just an explain:
            I like rounding. Thus, for example 43min => 45 and 42min => 40.
            The minutes are base 60, so you have to make modulus 60.
    */
    if (this.options.roundmodfive) {
        this.minutes = (Math.round(parseInt(this.minutes) / 5)) * 5 % 60;
    }

    var value = leadingZero(this.hours) + ':' + leadingZero(this.minutes);
    if  (this.options.twelvehour) {
        value = value + this.amOrPm;
    }
...
