密码验证 - Javascript
我想验证密码字段。我尝试过以下代码，但收到消息“您的密码必须满足以下条件............”，即使我输入了正确的密码格式。
var re = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{4,8}$/;
if ( !re.test(rpassword) )
{
alert('Your password must satisfy the following. \n\n* Password should be 4 to 8 character long. \n* Password should have at least one alphabet. \n* Password should have at least one numeric value. \n* Password should have special characters.');
return false;
}
不明白这段代码有什么问题。请帮忙！！

您确定不想要：
??您说“rpassword”是对表单中密码元素的引用。如果是这样，那么你必须首先获取它的“value”属性。
Are you sure you don't want:
?? You say that "rpassword" is a reference to the password element in your form. If so, then you have to get its "value" attribute first.
你能试试这个正则表达式吗？
could you try this regular expression?
