加载页面时运行函数
我的身体内部有一个脚本，一个相对较长的脚本，我想把它放在一个单独的 .js 文件中，然后只在身体加载时调用该函数，而不是将脚本放在正文中，但我不知道如何称它为。帮助？
脚本：
<script type="text/javascript">
// Set the number of snowflakes (more than 30 - 40 not recommended)
var snowmax = 35
// Set the colors for the snow. Add as many colors as you like
var snowcolor = new Array("#ddddff", "#ccccdd", "#f3f3f3", "#f0ffff")
// Set the fonts, that create the snowflakes. Add as many fonts as you like
var snowtype = new Array("Times", "Arial", "Times", "Verdana")
// Set the letter that creates your snowflake (recommended: * …我想让我的javascript从数组中打印一个随机引用.我设法做到了这一点,但不知道如何控制写入的位置.我希望在div中写出来.救命？

quotes = [];
quotes[0] = "I have a new philosophy. I'm only going to dread one day at a time.";
quotes[1] = "Reality is the leading cause of stress for those in touch with it.";
quotes[2] = "Few things are harder to put up with than the annoyance of a good example.";

HTML:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Josue Espinosa</title>
<link href="style.css" rel="stylesheet" type="text/css">
<script src="animate.js"></script>
<script src="http://code.jquery.com/jquery-latest.min.js"
type="text/javascript"></script>
</head>
<body>
<div id="menu">
</div>
</body>
</html>
CSS:
#menu{
width:15px;
height:200px;
background:red;
}
jQuery的:
$('#menu').hover(function(){
$("#menu").stop().animate({width : "300px"});
});
我不确定为什么这不起作用:
if ($('#menu').width() == '200px') {
alert("what");
}
我希望在动画完成时显示警报.所以我假设我可以说,因为当动画完成时,元素的宽度为200px,它会显示警告.
