No more nonsense, let me just post the code for you. 

<!DOCTYPE html>
<html>
<head>
<meta charset="{CHARSET}">
<title></title>
</head>
<body>
</body>
<script type="text/javascript">
//在Ｊａｖａｓｃｒｉｐｔ脚本中，将字符串按指定符号进行分割成数组用ｓｐｌｉｔ（）的方法
//格式StringObject.split( char [,howmany]);
//char: 必需。字符串或正则表达式howmany: 可选。
//该参数可指定返回的数组的最大长度。
//如果设置了该参数，返回的子串不会多于这个参数指定的数组。
//如果没有设置该参数，整个字符串都会被分割，不考虑它的长度。
var arr1="2:3:4:5".split(":");
document.write(arr1+"<br/>");
document.write(typeof(arr1)+"<br/>");
var arr2="|d|b|g".split("|");
document.write(arr2+"<br/>");
document.write(typeof(arr2)+"<br/>");
//希望把单词分割为字母，或者把字符串分割为字符，可使用下面的代码：
var arr3="love".split("");
document.write(arr3+"<br/>");
document.write(typeof(arr3)+"<br/>");
//以上操作实际上返回的是一个数组，具体访问某个元素，用arr[0],arr[1].......
</script>
</html>
