验证代码片段:

private function isValidPassword(value:String):Boolean
{
    if(value.length < minLength)
    	return false;
    var regexArray:Array = [/[A-Z]/, /\d/, /[a-z]/, /[^\w]/];
    var flag:Boolean = true;
    var result:Object;
    for(var i:Number = 0; i < regexArray.length; i++)
    {
    	result = RegExp(regexArray[i]).exec(value);
    	if(!result)
    	{
    		trace(value + " fails test " + i);
    		return false;
    	}
    }
    return true;
}

1. /A-Z/ 验证至少一个大写字母

2. /a-z/ 验证至少一个小写字母

3. /\d/ 验证至少一个数字

4. /[^\w] 验证至少一个非单词字符, 注意: 正则将 _ (下划线)计算为一个字符

补充: 如果需要把_(下划线)包含进去,正则就应该这样写: /[^\w]|_/

下面是一个完整的例子:
