tree结构统一修改属性名（递归）

 1 //data为需要修改的tree，这里主要是为antd design 里面select规范数据
const ass = (data) => {
        let item = [];
        data.map((list, i) => {
                let newData = {};
                newData.key= list.id;
                newData.value = list.id;
                newData.title = list.name;
                newData.children = list.children  ? ass(children) : [];    //如果还有子集，就再次调用自己
                item.push(newData);
        });
        return item;
 }
