javascript - 如何防止 jQuery bootstrap ClockPicker 获得不可被 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以被 5 整除的时间。例如，如果用户选择 13:08，ClockPicker 应该选择 13:05。

有没有办法覆盖时钟选择器来舍入选定的时间分钟？

Answer 1

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

我解析输入的值并进行更改以获取新的分钟值。

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. 更改此项

// 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.由此

// 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;
    }
...
