Chapter 8 - Battleship game.

[KU740]

I am trying to hard code the ships and try to hit and sunk them, but the message that Ships were either, hit, or sunk, or were missed is not displaying on the webpage. Instead, it's displaying as Ships were sank all the time on top. I checked the console for Errors, and there were none. I don't know what's wrong in my code.

So far my code looks like this. And the console is not showing any errors.

var view = { 
displayMessage: function(msg){
	var messageArea = document.getElementById("messageArea");
	messageArea.innerHTML = msg;
},
displayHit: function(location){
	var cell = document.getElementById(location);
	cell.setAttribute("class","hit");
},
displayMiss: function(location){
	var cell = document.getElementById(location);
	cell.setAttribute("class","miss");
}

};


view.displayMiss("00");
view.displayHit("34");
view.displayHit("12");
view.displayMiss("25");

view.displayMessage("are you on?");

var model = {
	boardsize: 7,
	numships: 3,
	shipLength: 3,
	shipSunk: 0,
 ships: [{ locations: ["06", "16", "26"], hits: ["hit", "", ""] },
 { locations: ["24", "34", "44"], hits: ["", "", ""] },
 { locations: ["10", "11", "12"], hits: ["", "", ""] }],
fire: function(guess) {
	for(var i = 0; i < this.numships; i++){
		var ship = this.ships[i];
		var index = ship.locations.indexOf(guess);
		if(index >=0){
			ship.hits[index] = "hit";
			view.displayHit(guess);
			view.displayMessage("HIT!");
			if (this.isSunk(ship)){
				view.displayMessage("You sank my warship");
				this.shipSunk++;
			}
			return true;
		}
	}
	view.displayMiss(guess);
	view.displayMessage("You Missed.");
	return false;
	
	},
	isSunk: function(ship) {
		for (var i = 0; i < this.shipLength; i++){
			if (ship.hits[i] !== "hit"){
				return false;
			}
		}
		return true;

	}
