Javascript 如何分配val onClick

我正在与以下人员合作：

HTML:

石头、布、剪刀、蜥蜴、斯波克

CSS:

var choices={rock:{name:“rock”，击败：{剪刀：“crushes”，蜥蜴：“crushes”}，
报纸：{名字：“报纸”，失败：{摇滚：“封面”，斯波克：“反驳”}，
剪刀：{名字：“剪刀”，失败：{纸：“剪”，蜥蜴：“斩首”}，
蜥蜴：{名字：“蜥蜴”，击败：{报纸：“吃”，斯波克：“毒药”}，
斯波克：{名字：“斯波克”，击败：{剪刀：“粉碎”，石头：“蒸发”}
};
var computerChoice=Math.random（）；
if（computerChoice非常简单！有两种选择：


在HTML中使用内联JavaScript

使用JavaScript-domapi来完成这项工作
