[FIXED] How do I convert the value of an "input type week" into date or numeric

Issue

I have an element in html5:

<input class="form-control" #semana="ngModel" name="semana" [(ngModel)]="detalle.semana" type="week">

The value I get is a string "2018-W23" for example. What I want is to get the value in date or number entered to perform operations on it (add or subtract days) and save it in my database.

I am working with Angular 5, JAVA spring and MySQL

Solution

You need a conversion function to get a Date object from your week input.

See this discussion : javascript calculate date from week number

It appears there is no standard JS function to do that, so you have to implement your own function (again, see discussion - link above) to parse the week input into a Date object.

Then with your Date object it will be convenient to do operations (add days etc) and save it to your database.
