jquery的项目，html页面使用vue3 +element Plus

vue3，element引入

<script src="../vue3.3.8/vue.global.js"></script>
<link rel="stylesheet" href="js/elementPlus/index.css">
<script src="js/elementPlus/index.full.js"></script>

1.点击事件绑定

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Title</title>
  <script src="../vue3.3.8/vue.global.js"></script>
  <link rel="stylesheet" href="js/elementPlus/index.css">
  <script src="js/elementPlus/index.full.js"></script>
</head>

<body>
<div id="app">
  {{ message }}
  <el-button type="primary" @click="clickEvent">消息</el-button>
</div>
<script>
  const {createApp, ref, computed, reactive} = Vue
  const app = createApp({
    setup() {
      const message = ref('Hello vue!')
      clickEvent = (e) => {
        alert('点击事件')
        message.value = "new Hello"
      }
      return {
        clickEvent,
        message
      }
    }
  })
  app.use(ElementPlus)
  app.mount('#app')

</script>
</body>
</html>

2.动态修改值

点击事件重置message:

message.value = "new Hello"

3.jQuery方法调用vue3的数据与字段

const vm=app.mount('#app')，mount之后返回vm实例对象，通过vm拿到setup里返回的东西。

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Title</title>
  <script src="../vue3.3.8/vue.global.js"></script>
  <link rel="stylesheet" href="js/elementPlus/index.css">
  <script src="js/elementPlus/index.full.js"></script>
  <script src="js/jquery/jquery-1.9.1.min.js"></script>
</head>

<body>
<div id="app">
  {{ message }}
  <el-button type="primary" @click="clickEvent">消息</el-button>
</div>
<script>
  const {createApp, ref, computed, reactive} = Vue
  const app = createApp({
    setup() {
      const message = ref('Hello vue!')
      clickEvent = (e) => {
        alert('点击事件')
        message.value = "new Hello"
      }
      return {
        clickEvent,
        message
      }
    }
  })
  app.use(ElementPlus)
 const vm=app.mount('#app')
  console.log(">>>", app)

  $(function () {
    console.log(">>>jquery")
    console.log(">>>jquery",  vm,vm.message)
    vm.clickEvent()
  })

</script>
</body>
</html>

效果
