Store response from input.

Hello,

I am trying to create a quiz. For each question I have added a text input, so that the user can write their answer. How can I get that answer and store it in a variable for use later on?

I have tried the following:

var answerOne = document.getElementById("answer-one").value;

This did not work. The console responded with the message "Cannot read property 'value' of null". My code needs improving, how should I approach this to write DRY code.

Thanks!

That error message likely means there is nothing on your HTML page with the id of answer-one. The getElementById() will return null because it can't find anything, and null has no properties, hence the error message.
