How to access newly created object's variable?
So I have this blueprint object:
function User (theName, theEmail) {
this.name = theName;
this.email = theEmail;
this.quizScores = ;
this.currentScore = 0;
}
I create a new user like this var user1 = new User (theName.value, theEmail.value); which is inside a function for event listener when user types in his name and email. Now there are questions and a button for next question. Everytime user clicks next question button, I want to increment currentScore by one. Problem is that it stays 0 all the time. I do it like this:
scoretag = document.createElement("p");
scoretag.innerHTML = user1.currentScore;
body.appendChild(scoretag);
Event listener and main loop:
for (var i = 0; i < theChoices[question1.theChoices].length; i++) {
var arrayQ = document.createElement("p");
arrayQ.innerHTML = theChoices[question1.theChoices][i];
list.appendChild(arrayQ);
var radio = document.createElement("input");
radio.type = "radio";
listOptions.appendChild(radio);
dbtn.addEventListener("click", function() {
//list.removeChild(arrayQ);
//listOptions.removeChild
list.removeChild(list.firstChild);
list.removeChild(list.lastChild);
user1.currentScore = user1.currentScore+1;
scoretag = document.createElement("p");
scoretag.innerHTML = user1.currentScore;
body.appendChild(scoretag);
})
}
UPDATE: I putted the code for appending a child to a body element inside the loop after incrementation of score, but this results in many numbers printed on the page one after another.
But like I said, when I try t increment by one on button click, it still keeps showing 0 on the screen. Any help?
