vue-codemirror看了一下文档找到了api、但是不知道这个doc.是什么意思，我试过this.$refs.myEditor不行，请问怎么调用https://codemirror.net/doc/ma...<;template> <div> <codemirror style="height:100%;" ref="myEditor" :value="editorJson" ></codemirror> </div></template><script> import {codemirror} from "vue-codemirror-lite"; export default { name: "PreviewCode", props: { fileFormat: { type: String, default: "json" }, editorJson: { type: String, default: "" } }, data() { return { visible: false }; }, components: { codemirror } };</script>
