 ### 动态绑定多个值
 <!--rehype:wrap-class=row-span-2-->
 
-```js
-data() {
-  return {
-    objectOfAttrs: {
-      id: 'container',
-      class: 'wrapper'
-    }
-  }
-}
-```
-
 通过不带参数的 `v-bind`，你可以将它们绑定到单个元素上
 
-```html
-<div v-bind="objectOfAttrs"></div>
+```vue
+<script setup>
+  import comp from "./Comp.vue"
+  import {ref} from "vue"
+  const a = ref("hello")
+  const b = ref("world")
+</script>
+
+<template>
+  <comp v-bind="{a, b}"></comp>
+</template>
+```
+
+如果你是使用的 `setup` 语法糖。需要使用 `defineprops` 声名（可以直接使用`a`/`b`）
+
+```js
+const props = defineProps({
+  a: String,
+  b: String
+})
