var startsWithCap = /^[AZ]/.test(Element.name）;
因为这不包括é，？等我宁愿用
var firstChar = Element.name.charAt（0），
startsWithCap = firstChar.toUpperCase（）== firstChar;
ciao，dhgm
var beginsWithCap = /^[A-Z]/.test(Element.name);
Since this does not cover "é", "?" etc., I would rather use
var firstChar = Element.name.charAt(0),
beginsWithCap = firstChar.toUpperCase() == firstChar;
ciao, dhgm

OP写了一个名字;该字段可能包含类似dietmar
meier的内容，在这种情况下需要进行两次检查。
他可能需要比那;姓氏包括诸如O'B $ b O'Brien，McCarthy，Chomondeley-Featherstonehaugh和适当等姓氏。姓名
包括教皇格雷戈里十三世。

The OP wrote "a name"; the field might contain something like "dietmar
meier", in which case two checks would be needed.
And he may need to be more careful than that; surnames include such as
O''Brien, McCarthy, Chomondeley-Featherstonehaugh, and "proper" names
include such as Pope Gregory XIII.

如果是这种情况，我会建议
var s = Element.value，
e = 0，
有效= s.replace（
/ \ b\S / g，
函数（a）{
e | = a！= a.toUpperCase（）;
}
），！e;
他可能需要更加小心;姓氏包括诸如O'Brien，McCarthy，Chomondeley-Featherstonehaugh和适当等姓氏。姓名

If that''s the case, I would suggest
var s = Element.value,
e = 0,
valid = s.replace(
/\b\S/g,
function(a) {
e |= a != a.toUpperCase();
}
), !e;
And he may need to be more careful than that; surnames include such as
O''Brien, McCarthy, Chomondeley-Featherstonehaugh, and "proper" names

另一方面，Piet van der Falk，Karl von und zum Stein，等等。
应被视为有效名称。
ciao，dhgm
On the other hand, "Piet van der Falk", "Karl von und zum Stein", etc.
should be considered as valid names.
