TypeError：无法读取未定义的属性“ onload”

Question

我正在尝试在VueJS函数中调用我的JQuery，但确实给了我TypeError错误：无法读取未定义的属性“ onload”。

    <script>
import show from "C:/Users/vincent.dizon/Desktop/FrontEnd/frontend/public/show";

export default {

    alertVin: function() {
      show.window.onload()
    },
    clickMe: function() {
      alert("YOU CLICKED ME");
    }
  }

</script>

这是我的 show.js

   export var myFunction = window.onload = function () {
    const btn = document.querySelector('#show-form');
    const form = document.querySelector('.form');
    const close = document.querySelector('.close-container');

    btn.addEventListener('click', () => {
        form.classList.add('form-show');
        close.classList.add('x-show');

    })
    close.addEventListener('click', function () {
        close.classList.remove('x-show');
        form.classList.remove('form-show');
    })
}

编辑：更新了SHOW.JS
