Encountering an error in Angular 2: "date.getMonth is not a function

I am currently utilizing the Angular-2-datepicker in my project. Everything seems to be functioning properly, but whenever I attempt to set the [(date)] attribute, an error is thrown.

An error stating that date.getMonth is not a function keeps popping up.

After doing some research, it appears that this issue may arise because my variable is not of type date. However, upon checking, mine actually is. As a result, I have hit a roadblock and cannot seem to find a solution.

This is how my HTML looks:

...
<material-datepicker dateFormat="DD-MM-YYYY" weekStart="1" [(date)]="definitionDetails.From"></material-datepicker>
...

This is my Model structure:

export class ClosingDayDefinition implements Serializable<ClosingDayDefinition> {

    ID: number;
    DescriptionID: number;
    Info: models.DefinitionDetailInfo;
    Description: models.DefinitionDescription;
    CodeId: number;
    From: Date;
    To: Date;
    Recurring: boolean;
    Holiday: boolean;
    Groups: Array<models.ClosingDayGroup>;
    TypeName: string;

Here's how my Component is defined:

...
public definitionDetails: models.ClosingDayDefinition;
...

Furthermore, here's what was recorded in the Var Log:

Answer №1

It appears that the data in the From property is in string format rather than being a proper Date object.

If you are retrieving this date string from an API, consider converting it into a Date object instead of directly storing it:

You can achieve this by:

new Date('2017-03-08T00:00:00+01:00')
