事件onClick之后，我可以更改车把吗？

如何解决事件onClick之后，我可以更改车把吗？

例如，我有一些bags.json

[
 {"parameters": ["a","b","c","d","e"],"size_1":["1","2","3"],"size_2":["5","6","7"],"size_3":["9","10","11"],"size_4":["1","3","5"],"size_5":["2",}
]

我将此JSON发送到服务器端（routes / index.js）

const express = require("express");
const fs = require("fs");
const router = express.Router();

let rawdata = fs.readFileSync("./public/bags.json");
let bags = JSON.parse(rawdata);

router.get("/",(req,res) => {
 res.render("constructor",{
    bags: bags,});
});
module.exports = router;

我的构造函数。把手

{{#each bags}}
{{#each parameters}}
  <input type="radio" name="field" value="{{@key}}" required>
  <p>{{this}}</p>
{{/each}}
<select>
 {{#each }} <--- {{!-- {{#each size_1/size_2/...}} --}}
   <option>{{this}}</option>               
 {{/each}}
</select>
{{/each}}

如何为input type="radio"单击<p>a</p>并仅显示size_1的值，对于<p>b</p>仅显示来自size_2的值，等等。

或将size_1从{{#each size_1}}更改为size_2，size_3，...
