在 json对象增加对象

fetchData(id) {
      fetchArticle(id).then(response => {
        this.responseData = response.data
        let jsonD = new Object();
        for( const key in this.responseData ){
          let idD = new Object();
          idD.value = this.responseData[key];
          idD.edit = false;
          const keys = key;
          jsonD[keys] = idD;
        }
        alert(JSON.stringify(jsonD));

输出

注意：let jsonD = new Object();一定要放在循环外面，要不value的值会如下显示
