Javascript：检查已选择哪个单选按钮

Question

我已经检查了论坛，找不到任何直接有助于或与我的问题有关的内容，因此请继续。 我正在为学校制作游戏，并且为该玩家显示3个班级，每个班级旁边都有一个单选按钮。 我希望我可以单击一个单选按钮，然后在做出最终决定（关于要选择哪个班级）之后，可以单击底部的按钮，然后继续游戏。

标签底部的区域似乎无效。 我收到错误消息“未捕获的ReferenceError：未定义VM68 classSelect.html：52的continueCheck”

您的语法全都提高了：

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

看看行尾有一个随机的“）”吗？

编辑：我想你可能打算写：

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");
    }
}
