Enhance user interface by dynamically updating date options

Incorporating AngularJS ui-date to link Jquery datepicker, I currently have two date pickers on my page - one labeled 'start' and the other 'end.'

I am seeking a way to modify the initial value of the end date based on the start date. Is there a method to dynamically alter the options of the datepicker?

For example:

If StartDate is set to 7th Sep, 2013, then the End Date should be constrained to a minimum date of 8th Sep, 2013.

I recently encountered the same issue and found a solution that worked for me:

Assuming you have the following HTML structure:

<div ng-controller="MyDateCtrl">
    <input ui-date="fromDatePickerOptions" type="text" ng-model="date.from" />
    <input ui-date="toDatePickerOptions" type="text" ng-model="date.to" />
</div>

In your JavaScript file, you would typically write something like this:

function MyDateCtrl($scope) {
    $scope.date = {
        from: new Date(),
        to: new Date()
    };

    $scope.fromDatePickerOptions = {
      dateFormat: 'M dd, yy'
    };

    $scope.toDatePickerOptions = {
      dateFormat: 'M dd, yy'
    };

    $scope.$watch('date', function() {
      // Perform any necessary date validations or adjustments here
      $scope.fromDatePickerOptions.maxDate = $scope.date.to,
      $scope.toDatePickerOptions.minDate   = $scope.date.from;
    }, true);
}

The second argument of $watch() with true ensures that object comparison is done based on equality rather than reference (as per AngularJS documentation).

Updating $scope.fromDatePickerOptions and $scope.toDatePickerOptions triggers a reload of the options in the ui-date directives.

Following these steps resolved the issue for me, hopefully it helps you as well!
