Question

美好的一天，此源现在允许我预选默认国家/地区。但我需要预先选择默认状态。无法弄清楚如何修改脚本。基本上我想将我的PHP代码绑定到选择框形式，并且每个帐户都能够预先选择国家/地区阶段。非常感谢帮助。

// ////////////////这包括JAVA脚本文件TITLED countries.js ///////////////

Fighter

现在我们看看HTML的实现。

from player import Player


# TODO implement fighter stats and attacks

class Fighter(Player):
    """
    Fighter class, a strong warrior that uses meele attacks to face his opponents
    """

    def __init__(self):
        super().__init__(armor_class=10)
        print("\nYou have chosen the path of strength!")
        self._strength += 2
        self._constitution += 2
        self.atk_bonus += 1
        self.atk_dmg += 3

    def hack_and_slash(self):
        from skills import ActiveSkill
        hack_and_slash = ActiveSkill("Hack n' Slash", "A powerful double attack that has a chance of causing bleeding.",
                                     8, 3)
        self.mp -= hack_and_slash.mp_use

    def __str__(self):
        super().__str__()

代码工作正常，我可以预先选择加拿大，但我也希望传递状态变量。无法弄清楚如何修改代码。

在动态国家/地区选择中运行java脚本。如何更改状态的默认选择？
