Answer
You did not specify an incomplete call to the selector – getElementById('survey');
. The rule is to use the document
, and you need to write like this – document.getElementById('survey');
.
Next, you have an undefined variable sel
, and I mean that this variable is filled with data from document.getElementById('survey');
. It turned out like this – let sel = document.getElementById('survey');
Now run this code and try to select a value from the dropdown list. There are no errors.
That is how it should be?
/*the code isn't finish, this error block me(code name is sur.js*/ let choi; let choix1 = 1; let choix2 = 1; let choix3 = 1; function submit(){ console.log(choi); } function changer(){ let sel = document.getElementById('survey'); choi= sel.options[sel.selectedIndex]; console.log(choi); }
