I am trying to read the enteredValue variable outside the function but the value outside the function remains undefined:

var enteredValue;

$("input").on("keydown",function search(e) {
    if(e.keyCode == 13) {
        alert($(this).val());
        enteredValue = $(this).val().trim().toUpperCase()
        console.log("Code inside: " + enteredValue); //value is read
    }
});

console.log("Code outside : " + enteredValue); //value undefined

Can you please tell me what I'm doing wrong?

Please add to code snippet..! – Tushar Acharekar Feb 19 '18 at 09:05

nothing is wrong. `enteredValue` is undefined until you press a key in your input file – scraaappy Feb 19 '18 at 09:05

You are trying to read the value when it hasn't been initialized yet... code inside event handler is executed after the `console.log` written outside. – gurvinder372 Feb 19 '18 at 09:05

agreed with @gurvinder372 . Please check here:-https://jsfiddle.net/cpd4u5La/ (when page loaded check the console) – Alive to die - Anant Feb 19 '18 at 09:11
Can I somehow make the value available outside the function i.e. when I log the Code outside I see the same value inside the function? – fbdg Feb 19 '18 at 09:55
Just initialise it as a `String` (or whatever datatype you need) in the beginning: `var enteredValue = "";` – Master Yoda Feb 19 '18 at 10:07
@MasterYoda the value is still not the one I am declaring in the function – fbdg Feb 19 '18 at 20:03
