如何在功能组件中渲染嵌套元素？

Question

我正在弄清楚如何在组件和功能组件中呈现多个根元素是解决方案，对我来说一切正常，但不确定如何呈现嵌套元素。

请检查 comment 代码中我描述的对我有用的部分。

export default {
  name: 'MyFnlComp',
  functional: true,
  render(createElement, { props }) {
    const itemIndex = props.item.index;
    const nestedEle = createElement('div', {}, 'nested element goes here');

    const catCard = createElement('div', {}, nestedEle); // this doesn't work :(
    const userCards = createElement('div', {}, 'Hey! this works'); // this works :)

    return [catCard, userCards];
  },

};

Answer 1

createElement 的最后一个参数应该是字符串或数组..

const catCard = createElement('div', {}, [nestedEle]);
