How to usemultiple Angular UI Bootstrap Datepicker

问题:

I have a form where there is a need for me to have 2 or more date fields for different things. I tried the Angular UI Bootstrap which works fine when I have only 1 date field in the form. But it stops working if I have multiple date fields and I dont know the easier method to get this to work.

This is my HTML sample:

 <label>First Date</label>  
    <div class="input-group">
     <input type="text" class="form-control" datepicker-popup="{{format}}" name="dt" ng-model="formData.dt" is-open="opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" />
      <span class="input-group-btn">
        <button class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>      

 <label>Second Date</label>  
    <div class="input-group">
     <input type="text" class="form-control" datepicker-popup="{{format}}" name="dtSecond" ng-model="formData.dtSecond" is-open="opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" />
      <span class="input-group-btn">
        <button class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>     

My JS is:

myApp.controller('DatePickrCntrl', function ($scope) {

      $scope.today = function() {
        $scope.formData.dt = new Date();
      };
      $scope.today();

      $scope.showWeeks = true;
      $scope.toggleWeeks = function () {
        $scope.showWeeks = ! $scope.showWeeks;
      };

      $scope.clear = function () {
        $scope.dt = null;
      };

      // Disable weekend selection
      $scope.disabled = function(date, mode) {
        return ( mode === 'day' && ( date.getDay() === 0 || date.getDay() === 6 ) );
      };

      $scope.toggleMin = function() {
        $scope.minDate = ( $scope.minDate ) ? null : new Date();
      };
      $scope.toggleMin();

      $scope.open = function($event) {
        $event.preventDefault();
        $event.stopPropagation();

        $scope.opened = true;
      };

      $scope.dateOptions = {
        'year-format': "'yy'",
        'starting-day': 1
      };

      $scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'shortDate'];
      $scope.format = $scope.formats[0];

});

I implemented based on the sample here. The problem I have here is:

1) When one of the date field is clicked, the pop-up datepicker is messed up and seems to show 2 datepicker in 1.

2) When I remove is-open="opened" attribute, the pop-up window seems to work fine. But without is-open="opened", the ng-click="open($event) for the button doesnt work.

3) Since each of the date fields have different ng-models, I am unable to set default dates for any date fields except for the first one with ng-model="formData.dt"

The only long way to resolve this that I can think of is to separate the controller for each date field.

I would like to know how others implement multiple date fields in 1 form itself when using Angular UI Bootstrap.

I have 30 in one form one controller no problem. use the same concept if you need it on ng-repeat.

 <label>First Date</label>  
    <div class="input-group">
     <input type="text" class="form-control" datepicker-popup="{{format}}" 
            name="dt" ng-model="formData.dt" is-open="datepickers.dt" 
            datepicker-options="dateOptions" ng-required="true" 
            close-text="Close" />
      <span class="input-group-btn">
        <button class="btn btn-default" ng-click="open($event,'dt')">
            <i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>      

 <label>Second Date</label>  
    <div class="input-group">
     <input type="text" class="form-control" datepicker-popup="{{format}}" 
            name="dtSecond" ng-model="formData.dtSecond" 
            is-open="datepickers.dtSecond" datepicker-options="dateOptions" 
            ng-required="true" close-text="Close" />
      <span class="input-group-btn">
        <button class="btn btn-default" ng-click="open($event,'dtSecond')">
            <i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>     

myApp.controller('DatePickrCntrl', function ($scope) {
      $scope.datepickers = {
        dt: false,
        dtSecond: false
      }
      $scope.today = function() {
        $scope.formData.dt = new Date();

        // ***** Q1  *****
        $scope.formData.dtSecond = new Date();
      };
      $scope.today();

      $scope.showWeeks = true;
      $scope.toggleWeeks = function () {
        $scope.showWeeks = ! $scope.showWeeks;
      };

      $scope.clear = function () {
        $scope.dt = null;
      };

      // Disable weekend selection
      $scope.disabled = function(date, mode) {
        return ( mode === 'day' && ( date.getDay() === 0 || date.getDay() === 6 ) );
      };

      $scope.toggleMin = function() {
        $scope.minDate = ( $scope.minDate ) ? null : new Date();
      };
      $scope.toggleMin();

      $scope.open = function($event, which) {
        $event.preventDefault();
        $event.stopPropagation();

        $scope.datepickers[which]= true;
      };

      $scope.dateOptions = {
        'year-format': "'yy'",
        'starting-day': 1
      };

      $scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'shortDate'];
      $scope.format = $scope.formats[0];

});


 // ***** Q2 ***** somemodel can be just an array [1,2,3,4,5]
 <div ng-repeat="o in somemodel">
 <label>Date Label</label>  
    <div class="input-group">

            <i class="glyphicon glyphicon-calendar"></i></button>
      </span>
    </div>
  </div>


myApp.controller('DatePickrCntrl', function ($scope) {

      $scope.datepickers = {
        data: {},
        options: {
            'year-format': "'yy'",
            'starting-day': 1
        },
        isopen: {}
      }
      $http.get("get/data/for/some/model", function(result) {
         $scope.somemodel = result;
         for (var i = 0; i < result.length; i++) {
           $scope.datepickers.isopen[result] = false;
           $scope.datepickers.data[result] = new Date(); //set default date.
         }
      });

  // fill in rest of the function
});

Simpler Solution. Requires only modding the HTML and can be used in a ng-repeat if you like. Just be creative with what you name the opened

Stick this in your Controller:

$scope.calendar = {
    opened: {},
    dateFormat: 'MM/dd/yyyy',
    dateOptions: {},
    open: function($event, which) {
        $event.preventDefault();
        $event.stopPropagation();
        $scope.calendar.opened[which] = true;
    } 
};

HTML:

<div class="form-group row">
    <div class="col-lg-6">
        <label for="formDOB">Date of Birth</label>
        <p class="input-group">
          <input type="text" class="form-control" datepicker-popup="{{calendar.dateFormat}}" ng-model="record.birthDate" is-open="calendar.opened.dob" datepicker-options="calendar.dateOptions" close-text="Close" placeholder="Date of Birth" />
          <span class="input-group-btn">
            <button type="button" class="btn btn-default" ng-click="calendar.open($event, 'dob')"><i class="glyphicon glyphicon-calendar"></i></button>
          </span>
        </p>
    </div>
    <div class="col-lg-6">
        <label for="formWinDate">Win Date</label>
        <p class="input-group">
          <input type="text" class="form-control" datepicker-popup="{{calendar.dateFormat}}" ng-model="record.winDate" is-open="calendar.opened.win" datepicker-options="calendar.dateOptions" close-text="Close" placeholder="Win DAte" />
          <span class="input-group-btn">
            <button type="button" class="btn btn-default" ng-click="calendar.open($event, 'win')"><i class="glyphicon glyphicon-calendar"></i></button>
          </span>
        </p>
    </div>
</div>

回答3:

wayne's answer is great. I would only add, that you can make the function 'open()' better:

$scope.open = function ($event, datePicker) {
    $event.preventDefault();
    $event.stopPropagation();

    $scope.closeAll();
    datePicker.opened = true;
};

And then you have to use it like that:

ng-click="open($event, dateFrom)"

Where dateFrom is your ng-model (i.e. you use $scope.dateFrom).

EDIT: $scope.closeAll(); is a function that closes all the datePickers. It can be written like that:

$scope.closeAll = function() {
    $scope.dateFrom.opened = false;
    $scope.dateTo.opened = false;
};

回答4:

I'd prefer not to mix ng-model with UI info.For this purpose, is necessary to define an array to store the opening flags, as well as checking if the datePicker is opened or not.

Moreover, I have changes the 'open' behavior to 'toggle' instead, in order to allow closinf the datePicker with the button.

Here is my controller:

$scope.toggleOpenDatePicker = function($event,datePicker) {
   $event.preventDefault();
   $event.stopPropagation();
   $scope[datePicker] = !$scope[datePicker];
};

Then it can be used as:

<input type="text" class="form-control" ng-model="model.date1" is-open="date1" />
   <span class="input-group-btn">
      <button type="button" class="btn btn-default" ng-click="toggleOpenDatePicker($event,'date1')"><i class="glyphicon glyphicon-calendar"></i>      
      </button>
   </span>

The $scope idea was borrowed from here:

I solved my problem by use this plunker with minor changes.

HTML

<div class="row">
    <div class="col-md-6">
        <p class="input-group">
          <input type="text" class="form-control" datepicker-popup="{{format}}" ng-model="dt" is-open="openDatePickers[0]" min-date="minDate" max-date="'2015-06-22'" datepicker-options="dateOptions" date-disabled="disabled(date, mode)" ng-required="true" close-text="Close" />
          <span class="input-group-btn">
            <button type="button" class="btn btn-default" ng-click="open($event, 0)"><i class="glyphicon glyphicon-calendar"></i></button>
          </span>
        </p>
    </div>
</div>
    <h4>Popup</h4>
<div class="row">
    <div class="col-md-6">
        <p class="input-group">
          <input type="text" class="form-control" datepicker-popup="{{format}}" ng-model="dt" is-open="openDatePickers[1]" min-date="minDate" max-date="'2015-06-22'" datepicker-options="dateOptions" date-disabled="disabled(date, mode)" ng-required="true" close-text="Close" />
          <span class="input-group-btn">
            <button type="button" class="btn btn-default" ng-click="open($event, 1)"><i class="glyphicon glyphicon-calendar"></i></button>
          </span>
        </p>
    </div>
</div>

and in controller

$scope.openDatePickers = [];
$scope.open = function ($event, datePickerIndex) {
   $event.preventDefault();
   $event.stopPropagation();

   if ($scope.openDatePickers[datePickerIndex] === true) {
      $scope.openDatePickers.length = 0;
   } else {
      $scope.openDatePickers.length = 0;
      $scope.openDatePickers[datePickerIndex] = true;
   }
};

my changes

instead numbers (0 or 1) i use $index in angular ng-repeat.

like this:

is-open="openDatePickers[**$index**]"

ng-click="open($event, **$index**)"

<p class="input-group">
   <input type="text" class="form-control" datepicker-popup="{{format}}" ng-model="dt" is-open="openDatePickers[$index]" min-date="minDate" max-date="'2015-06-22'" datepicker-options="dateOptions" date-disabled="disabled(date, mode)" ng-required="true" close-text="Close">
   <span class="input-group-btn">
      <button type="button" class="btn btn-default" ng-click="open($event, $index)"><i class="glyphicon glyphicon-calendar"></i></button>
   </span>
</p>

i used it in a different way and it looks a bit easier to me. I was using one of the mentioned approaches, but i was to lazy to create tons of calendars since i was running i a loop without having any static identifier. So this solution is just valid for you, if you want to create lots of calendars inside of a ng-repeat. Hope it helps!

That is the controller

       $scope.datepickers = {
            data: {},
            isopen: {}
       }
       // setting the defaults once
       for (var i = 0; i < $scope.array.length; i++) {
            $scope.datepickers.isopen[i] = false;
            $scope.datepickers.data[i] = new Date();
        }

        // aso..

        $scope.valuationDatePickerOpen = function($event, index) {
          if ($event) {
            $event.preventDefault();
            $event.stopPropagation();
          }
          $scope.datepickers.isopen[index] = true;
        };

And this is the HTML snipped inside my loop

<!-- ng-repeat="entry in array track by $index" --> 

<input type="text" class="form-control" 
       datepicker-popup="dd-MMMM-yyyy" 
       is-open="datepickers.isopen[$index]"
       ng-click="valuationDatePickerOpen($event, $index)"
       ng-model="entry.date" />
