Angular Material DatePicker date.toLocaleDateString is not a function

Question

I try to use the angular date picker and I get the following error:

TypeError: date.toLocaleDateString is not a function
at Object.defaultFormatDate [as formatDate] (angular-material.js:6860)
at DatePickerCtrl.configureNgModel.ngModelCtrl.$render (angular-material.js:7184)
at Object.<anonymous> (angular.js:25233)
at m.a.$get.m.$digest (angular.js:15707)
at m.a.$get.m.$apply (angular.js:15986)
at g (angular.js:10511)
at L (angular.js:10683)
at XMLHttpRequest.A.onload (angular.js:10624)

I gave an example from the code: https://material.angularjs.org/latest/#/demo/material.components.input

Corresponding HTML code:

            <div layout="" layout-sm="column">
            <md-input-container style="width:70%">
                <label>Company (Disabled)</label>
                <input ng-model="user.company" disabled="">
            </md-input-container>

            <md-datepicker ng-model="date" md-placeholder="Enter date"></md-datepicker>
        </div>

My controller

$scope.date={};
$scope.$watch('date', function () {
    console.log($scope.date);
});

Answer 1

toLocaleDateString is a native method of a date object, so it seems that your md-datepicker is not bound to a date. Without HTML and code that populates your data, it's hard to say for sure, but this is the most likely reason.

Initializing the datepicker using the new Date (), but when trying to initialize with the value returned from the server, I got the error above - despite the fact that they seem to be in the same format.

In the end, I had to explicitly create a Date object and then set its value using Parse.

        var date = ctrl.data.fromServer;
        ctrl.data.fromServer= new Date();
        if (date != undefined)
        {
            ctrl.data.fromServer.setTime(Date.parse(date));
        }
