vue2.6.10+vite2开启template模板动态编译的过程

<!-- 用来渲染元素的组件 -->
<script lang="jsx">
import Vue from 'vue'
export default {
  name: 'renderContent',
  props: {
    html: String,
    elImage: Boolean, // 是否把图片处理成el-image
  },
  data () {
    return {
    }
  },
  components: {
  },
  computed: {
  },
  render(h) {
    let htmlString = this.html || ''
    if(this.elImage === true) {
      // 把res中的updateDesc中的image处理成el-image
      // 匹配img的表达式
      let reg1 = new RegExp(/<img [^>]*src=['"]([^'"]+)[^>]*>/gi);
      if(htmlString) {
        htmlString = htmlString.replace(reg1, function (match, capture) {
          return `<el-image src="${capture}" style="max-width: 100%;" fit="contain" :preview-src-list="['${capture}']"></el-image>`
        });
      }
    }
    // 进行xss过滤
    htmlString = this.$utils.xssFilter(htmlString)
    const com = Vue.extend({
      template: `<div>${htmlString}</div>`
    })
    return h(com, {})
  }
}
</script>

module.exports = {
    ...,
    runtimeCompiler: true,
}

export default defineConfig({
    resolve: {
        alias: {
          ...,
          "vue": "vue/dist/vue.common.prod.js",
