我试图把一个JavaScript&#34;命运之轮&#34;进入我的HTML正文<div>
,但每次它出现在整个HTML的底部。
我有:
<body>
<div>
<script type="text/javascript" src="phaser.min.js" charset="utf-8"></script>
<script type="text/javascript" src="game.js" charset="utf-8"></script>
</div>
</body>
这是game.js
// the game itself
var game;
// the spinning wheel
var wheel;
// can the wheel spin?
var canSpin;
// slices (prizes) placed in the wheel
var slices = 8;
// prize names, starting from 12 o'clock going clockwise
var slicePrizes = ["VYHRAL SI", "Bohužial si nevyhral.", "Skús zatočiť znova!", "Bohužial si nevyhral.", "Vyhral si zľavu", "Bohužial si nevyhral.", "Skús zatočiť znova!", "Bohužial si nevyhral."];
