Why can't I get the day?

[Hybris]

var etaDate = new Date();
 etaDate = document.getElementById("etaDate").value;
 window.alert(etaDate);
 var day = etaDate.getDate();
    window.alert(day);

I have a form with some date inputfields. Now I need to check what day of the week a certain date is but I can't get the getDate() to return a value. The etaDate print out the correct date but alert(day) show nothing? Any ideas? Thanks.

I noticed it should be .getDay() but it is still not working..

What is "etaDate"? According to the code.

[Hybris]

Wierd. Its working if I split etaDate into substrings and use them to set a new date? Anyone know why that works but not to just use it direcly?

 

<input id="etaDate" class="inputClass" type="date" tabindex="5">

Try answering my question.

It should be a date I guess? In the inputfield I get a calendar where I can select a date and as I edited in above the type says date ^^ ?

If I type in 2020-01-01 as a date that is also what the etaDate alertbox displays?

 

eEDit:: Ahh so Im making it something else than date when i use .value?

Let's take a closer look at the first two lines.

var etaDate = new Date();
etaDate = document.getElementById("etaDate").value;

On the first line, you set etaDate to be a new Date instance. On the second line you throw away that Date and instead get a value from some input. Does that seem weird?

Also, the .value from a form field is always a string. Always.

Ahh ok thanks, 

is there another way of getting the value of a cell that returns the type too or is the type="" in html just for formatting the inputfield?

[requinix]

Not that I know of.

The value is a date. Feed it to Date and be done with it.
