在 bootstrap-datepicker 上突出显示某些日期

Question

我正在使用 bootstrap-datepicker 检查我的网站销售的日期，并且我想显示或突出显示至少有一次销售的日期。我可以在 JSON 上传递日期，然后将它们放入 Javascript 的数组中，但我不知道如何让 datepicker 获取日期并突出显示它们。

bootstrap-datepicker 有没有办法实现这一点？

Answer 1

这是另一个突出显示日期范围的示例：

var inRange=false;
$('#elementPicker').datepicker({
  beforeShowDay: function(date) {
    dateFormat = date.getUTCFullYear() + '-' + date.getUTCMonth() + '-' + date.getUTCDate();

    if (dateFormat == '2014-01-01') {
      inRange = true; //to highlight a range of dates
      return {classes: 'highlight', tooltip: 'Title'};
    }
    if (dateFormat == '2014-01-05') {
      if (inRange) inRange = false;  //to stop the highlight of dates ranges
      return {classes: 'highlight', tooltip: 'Title'};
    }
    if (inRange) {
      return {classes: 'highlight-range'}; //create a custom class in css with back color you want
    }
  }
});

Answer 2

$('#xxx').datepicker()
  .on('onRender', function(ev){
    if (ev.date.valueOf() == your date){
      return 'highlight';
    }
  });

可能会成功，虽然我不确定。

Answer 3

有一种简单的方法可以在引导日历中设置多个日期。 有一个属性 multidate 可用于选择。 在下面找到工作代码。

     $('.inline_date').datepicker({
        multidate: true,
        todayHighlight: true,
        minDate: 0,
    });

 $('.inline_date').datepicker('setDates', [new Date(2015, 7, 5), new Date(2015, 7, 8), new Date(2015, 7, 7)])

只有一个问题，高亮在点击时会被删除。并且需要一个月的时间。如果你想要 8 月的日期，那么你必须使用 7 而不是 8。

Answer 4

我使用 Knockout 绑定和 datepicker 属性“beforeShowDay”解决此问题：

function MainFilters() {
    var self = this;
    self.notAppliedDates = ko.observableArray([]);
    self.customDates = ko.observableArray(["14.06.2015", "20.06.2015", "26.06.2015", "10.06.2015", "29.06.2015"]);
}

ko.bindingHandlers.multiDatepicker = {
    init: function (element, valueAccessor, allBindings) {
        var customDates = allBindings.get("customDates");

        valueAccessor()();
        $(element).datepicker(
            {
                multidate: true,
                language: "ru",
                orientation: "top",
                beforeShowDay: function (date) {
                    var d = ConvertDateTostring(date, "dd.mm.yyyy");

                    if ($.inArray(d, customDates()) != -1) {
                        return {
                            classes: 'activeClass'
                        };
                    }
                    return;
                }
            }
        )
       .bind(
			'changeDate',
			function (e) {
			    var res = e.dates;
			    var value = [];
			    res.sort(function (a, b) { return a - b });
			    for (var i in res) {
			        value.push(res[i].asString());
			    }

			    valueAccessor()(value);
			}
		);
    },
    update: function (element, valueAccessor, allBindings, bindingContext) {

    }
};

function ConvertDateTostring(date, format) {
    if (!date) {
        return "";
    }
    if (format) {
        return dateFormat(date, format);
    }
    return dateFormat(date, "dd.mm.yy");
}

 .activeClass{
    background: #32cd32; 
  }

使用 datetimepicker 事件 show、update 和 change 需要突出显示日期。

博文here 解释了如何使用 Bootstrap Datetimepicker 来实现。

$('#datetimepicker').on('dp.show', function(e){
  highlight()
})
$('#datetimepicker').on('dp.update', function(e){
 highlight()
})
$('#datetimepicker').on('dp.change', function(e){
    highlight()
})

function highlight(){
 var dateToHilight = ["04/19/2019","04/20/2019","04/30/2019"];
 var array = $("#datetimepicker").find(".day").toArray();
 for(var i=0;i -1) {
       array[i].style.color="#090";
       array[i].style.fontWeight = "bold";
    } 
 }
 }

我在上面尝试了 Matias 的答案，但出现了故障。经过一些故障排除并稍微修改了 Matias 的答案，我设法创建了一个可行的解决方案。

如果您将以下代码粘贴到一个空白的 .html 文件中，那么您应该会看到一个带有日期小部件的输入框。

开始日期（2021 年 8 月 8 日）、结束日期（2021 年 8 月 26 日）和其间的日期应该有自己独特的配色方案。
