vue3中如何用vue2中的this

Posted 2022-01-26 晚星@

两种方案分别如下：

proxy = 》 this

<script  lang="ts">
import  getCurrentInstance, ComponentInternalInstance  from "vue";
export default function useCurrentInstance() 
  const  appContext  = getCurrentInstance() as ComponentInternalInstance;
  const proxy = appContext.config.globalProperties;
  return 
    proxy,
  ;

</script>

// @ts-ignore
<script  lang="ts">
import  getCurrentInstance, ComponentInternalInstance  from "vue";
export default function useCurrentInstance() 
  const  proxy  = getCurrentInstance() as ComponentInternalInstance;
  return 
    proxy,
  ;

</script>
