How to include a JavaScript object in a separate file
Question
I'm trying to include a separate .js file so I can pull in a class I created but it doesn't work, can someone tell me why?
playercharacter.js
function PlayerCharacter() {
this.x = 0;
this.y = 0;
this.dx = 5;
this.dy = 5;
}
PlayerCharacter.prototype.sayHello = function()
{
alert ('hello');
};
index.html
<html>
<head>
<script src="js/playercharacter.js" type="text/javascript" ></script>
</head>
<body>
<script type="text/javascript" >
var player = new PlayerCharacter();
player.sayHello();
</script>
</body>
</html>

You forgot wrap your JS-code into the <script> tags
<html>
<head>
<script src="js/playercharacter.js" type="text/javascript" ></script>
</head>
<body>
<script type="text/javascript" >
var player = new PlayerCharacter();
player.sayHello();
</script>
</body>
</html>

Your JavaScript code is not in a script tag.
<script>
var player = new PlayerCharacter();
player.sayHello();
</script>

您需要使用<script>标记将代码包含在主体中。
