【问题标题】:How to run multiple function with returns in Jquery datePicker option beforeShowDay如何在 Jquery datePicker 选项 beforeShowDay 中运行多个函数并返回
【发布时间】:2020-08-20 04:29:52
【问题描述】:

我使用日期选择器并在日历中标记日期。我有两个功能(工作日和日期)。 Workdays 确定并设置工作日。日期确定要着色的日期。每个功能都可以正常工作,但我必须在日历上同时执行。函数调用的顺序无关紧要。

有两种颜色不同的日子。

  var arrayLength = Object.keys(dates).length
  for (var i = 0; i < arrayLength; i++) {
    if (new Date(dates[i].date).toString() == date.toString()) {
      return [true, dates[i].type, dates[i].note];
    }
  }
  return [true, ''];

然后我定义哪些日子可以标记:

return [workingDays.indexOf (date.getDay ())> -1];

如何在 beforeShowDay 中同时调用两个返回?

var workingDays = [1,2,3,4,5];

var dates = [
  {date: '05/13/2020', type: 'highlightFull', note: 'note1'},
  {date: '05/11/2020', type: 'highlightSemi', note: 'note2'}
];


function highlightDays(date) {

  // return [workingDays.indexOf(date.getDay()) > -1]; // First Return

  var arrayLength = Object.keys(dates).length // Second
   for (var i = 0; i < arrayLength; i++) {
     if (new Date(dates[i].date).toString() == date.toString()) {
       return [true, dates[i].type, dates[i].note];
     }
   }
   return [true, ''];
}

$(document).ready(function() {
  
  $('#datepicker').datepicker({
    beforeShowDay: highlightDays
  });
   
});
td.highlightFull {
  border: none !important;
  padding: 1px 0 1px 1px !important;
  background: none !important;
  overflow: hidden;
}

td.highlightFull a {
  background: #ad3f29 url(bg.png) 50% 50% repeat-x !important;
  border: 1px #88a276 solid !important;
}

td.highlightSemi {
  border: none !important;
  padding: 1px 0 1px 1px !important;
  background: none !important;
  overflow: hidden;
}

td.highlightSemi a {
  background: #ffff33 url(bg.png) 50% 50% repeat-x !important;
  border: 1px #88a276 solid !important;
}

【问题讨论】:

  • 我没有看到任何一个例子都在使用。请进一步澄清问题并提供一个最小的、可重现的示例:stackoverflow.com/help/minimal-reproducible-example
  • workingDays 在哪里定义,它的值是什么?
  • 对不起,我在上面的代码中添加了缺失的变量。

【解决方案1】:

考虑这个例子。它首先查找 Workdays (M - F) 并添加一个类。如果那一天在您的对象中,则应用该突出显示。

$(function() {
  var dates = [{
      date: '05/13/2020',
      type: 'highlightFull',
      note: 'note1'
    },
    {
      date: '05/11/2020',
      type: 'highlightSemi',
      note: 'note2'
    }
  ];

  function highlightDays(date) {
    var res = [true, ""];
    if (date.getDay() > 0 && date.getDay() < 6) {
      res = [true, "workday"];
    }
    $.each(dates, function(k, v) {
      if (v.date === $.datepicker.formatDate("mm/dd/yy", date)) {
        res = [true, v.type, v.note];
      }
    });
    return res;
  }

  $('#datepicker').datepicker({
    beforeShowDay: highlightDays
  });

});
td.highlightFull {
  border: none !important;
  padding: 1px 0 1px 1px !important;
  background: none !important;
  overflow: hidden;
}

td.highlightFull a {
  background: #ad3f29 url(bg.png) 50% 50% repeat-x !important;
  border: 1px #88a276 solid !important;
}

td.highlightSemi {
  border: none !important;
  padding: 1px 0 1px 1px !important;
  background: none !important;
  overflow: hidden;
}

td.highlightSemi a {
  background: #ffff33 url(bg.png) 50% 50% repeat-x !important;
  border: 1px #88a276 solid !important;
}

td.workday {
  border: none !important;
  padding: 1px 0 1px 1px !important;
  background: none !important;
  overflow: hidden;
}

td.workday a {
  background: #ccccff url(bg.png) 50% 50% repeat-x !important;
  border: 1px #88a276 solid !important;
}

    【解决方案2】:

    我现在已经这样解决了。非常感谢您的支持!

    例如:周三、周六和周日现在在日历中被屏蔽,无法标记。

    $(function() {
      var dates = [{
          date: '05/13/2020',
          type: 'highlightFull',
          note: 'note1'
        },
        {
          date: '05/11/2020',
          type: 'highlightSemi',
          note: 'note2'
        }
      ];
    
    var workingDays = [6,0,3]; // 0 = Sunday
    
    function highlightDays(date) {
      var res = [true, ""];
      
      if(workingDays.indexOf(date.getDay()) > -1) {
        res = [false, ""];
      }
      
      $.each(dates, function(k, v) {
        if (v.date === $.datepicker.formatDate("mm/dd/yy", date)) {
          res = [true, v.type, v.note];
        }
      });
      
      return res;
    }
    
      $('#datepicker').datepicker({
        beforeShowDay: highlightDays
      });
    
    });
    td.highlightFull {
      border: none !important;
      padding: 1px 0 1px 1px !important;
      background: none !important;
      overflow: hidden;
    }
    
    td.highlightFull a {
      background: #ad3f29 url(bg.png) 50% 50% repeat-x !important;
      border: 1px #88a276 solid !important;
    }
    
    td.highlightSemi {
      border: none !important;
      padding: 1px 0 1px 1px !important;
      background: none !important;
      overflow: hidden;
    }
    
    td.highlightSemi a {
      background: #ffff33 url(bg.png) 50% 50% repeat-x !important;
      border: 1px #88a276 solid !important;
    }
