how to get value from html form to javascript

Question

The value is null

html input code and javasript:

var tanggal1 =  document.getElementById("tanggal1").value;
var tanggal2 =  document.getElementById("tanggal2").value;
alert(tanggal1);

I expected the output tanggal1 = <input type='date' name='tanggal1' id='tanggal1'/> value

I am voting to close this as off-topic because the problem cannot be reproduced without the HTML code. The question does not contain a minimal reproducible example. — Lomtrur
