例如:
function say () {
alert (arguments[0]+'说:'+arguments[1]);
}
say ('fanglor','fanglor is a boy !');
结果:弹出 fanglor 说:fanglor is a boy !

这个有点类似于php 中的 func_get_args() 函数,也是获取函数参数的数组。
例(以下是php代码):
function uses () {
$args =func_get_args();
if (!empty($args)) {
foreach ($args as $key => $val ) {
if (file_exists($val.'.php')) {
include "{$val}.php";
} else {
if (DEBUG) {
echo "{$val}.php 不存在!";
}
}
}
}
}
//再次封装 include
uses ('config','db');
自动装载 config.php 和 db.php ,如不存在,显示 {__file__}.php不存在.
