Question

这是我的绑定代码

ko.bindingHandlers.datepicker1 = { 
init: function(element, valueAccessor, allBindingsAccessor) { 
$(function() { 


$(element).parent().datetimepicker({ 
pickDate: false, 
pickSeconds: false 
}); 
}); 
//initialize datepicker with some optional options 
var options = allBindingsAccessor().datepickerOptions || {}; 
$(element).parent().on('changeDate', function() { 
$(element).change(); 
}); 

//when a user changes the date, update the view model 
ko.utils.registerEventHandler(element, "change", function(event) { 
//alert("asdf"); 

// var dp = $("#slottotime"); 
var value = valueAccessor(); 
var input = $(event.target); 
var val = input.val(); 
value(val); 
//alert(value()); 
event.stopPropagation(); 
event.preventDefault(); 
var currentTime = new Date(); 
var hours = currentTime.getHours(); 
currentTime.setMinutes(currentTime.getMinutes() + 30); 
var minutes = currentTime.getMinutes(); 
if (minutes < 10) 
minutes = "0" + minutes; 
var totime= hours +":"+ minutes ; 
// dp.val(totime); 

}); 
}, 
update: function(element, valueAccessor) { 
var widget = $(element).data("datetimepicker"); 
//when the view model is updated, update the widget 
if (widget) { 
widget.date = ko.utils.unwrapObservable(valueAccessor()); 
widget.setValue(); 
} 
} 
};

这是我的标记

我正在使用this，示例来自here日期时间选择器

问题是当点击时间图标时，它会在3分钟间隔内显示我的时间，如00 03 06 09

但我希望时间间隔为15分钟，比如00 15 30 45，所以有人可以告诉我该怎么办？

在审核了the source后，问题的根源在

中找到

fillMinutes: function() {
  var table = this.widget.find(
    '.timepicker .timepicker-minutes table');
  table.parent().hide();
  var html = '';
  var current = 0;
  for (var i = 0; i < 5; i++) {
    html += '<tr>';
    for (var j = 0; j < 4; j += 1) {
      var c = current.toString();
      html += '<td class="minute">' + padLeft(c, 2, '0') + '</td>';
      current += 3; //HERE
    }
    html += '</tr>';
  }
  table.html(html);
}

对函数的调用仅在小部件的init中发生一次。因此，您可以使用jQuery查找元素并插入所需的html。

(function () {

 var table = $('.timepicker .timepicker-minutes table');
 table.parent().hide();
 var html = "";
 var current = 0;
 while (current < 60) {
    var c = current.toString();
    html += '<td class="minute">' + padLeft(c) + '</td>';
    current += 15;
 }

 table.html(html);
})();

根据具体情况修改原始来源的padLeft：

var padLeft = function padLeft(s) {
 if (2 < s.length){ return s;}
 return Array(2 - s.length + 1).join('0') + s;
};
