Objects in an array contain a specific value

I am trying to build a Blackjack game in Javascript and wanting to determine if the Player's hand contains an "Ace".

I have an array for the Player's hand and Dealer's hand to contain all the cards, each card object has 3 values associated with it...the cards name, suit and value. How do you look specifically for the value "Ace" for each object in the array? 

function card(name, suit, value) {
    this.name = name;
    this.suit = suit;
    this.value = value;
}

var playerHand = [];

var drawOne = function() {
   var card = cardsInDeck.pop();
   return card;
}

var p1 = drawOne();
    playerHand.push(p1.value);
var p2 = drawOne();
    playerHand.push(p2.value);

    if ((playerHand.indexOf("Ace") > 0) && playerTotal > 21) {
        playerTotal -= 10;
    }

Any insight into how to approach this correctly would be appreciated.

Assuming playerHand is an array, you can try

var hasAce = playerHand.some( function( card ){
  return card.suite.toLowerCase() == "ace";  
});

Now just proceed with your rest of the logic

if ( hasAce && playerTotal > 21) {
    playerTotal -= 10;
}

Edit

Based on the updates shared by you, since you are only pushing the value rather than the object, indexOf will work just fine

if ((playerHand.indexOf("Ace") > 0) && playerTotal > 21) {
    playerTotal -= 10;
}
