Question

我已经检查过论坛，找不到任何可以直接帮助或与我的问题相关的内容，所以请点击此处。我正在为学校制作一个游戏，玩家会看到3个班级，每个班级旁边都有一个单选按钮。我想要的是我可以点击一个单选按钮，然后在我做出最终决定（关于哪个类）之后，我可以点击底部的按钮然后游戏继续进行。

<!-- Scripting -->

}

标签底部的区域似乎不起作用。我收到错误＆＃34; Uncaught ReferenceError：continueCheck未定义VM68 classSelect.html：52＆＃34;

Answer 1

你的语法全都搞定了：

if(document.getElementById("class_angel") value="Angel")

看看你的行尾有一个随机的“）”？

编辑：我认为可能意味着写：

function continueCheck()
{
    if(document.getElementById("class_angel").checked)
    {   
        console.log("You pressed Angel");
    }
    else if(document.getElementById("class_beast").checked)
    {    
        console.log("You pressed Beast");
    }
    else if(document.getElementById("class_spirit").checked)
    {

        console.log("You pressed Spirit");
    }
}

Javascript：检查选择了哪个单选按钮
