js中引入js

document.write("<script language='javascript' src='config.js'></script>");
document.write("<script language='javascript' src='utility.js'></script>");
document.write("<script language='javascript' src='player.js'></script>");
document.write("<script language='javascript' src='global.js'></script>");

然后在html文件中直接引入game.js即可

<script src ="game.js" ></script>
