}应用
tree 组件，应用 handleclick（）响应树节点点击，传递参数 pid（树节点的 id）
父组件向子组件传值：在父组件定义一个参数，而后把他绑定到要回填的组件上，在这里应用的是:id=”this.queryParam.pid”
在子组件应用 props，在 data 中定义 props：[绑定的 key]，这样就收到了，而后应用 setFieldsValue 回填到子组件表单中须要的地位。
setFieldsValue
在 ant 中通过 setFieldsValue 存储的相似是一种键值 对的模式，你能够通过对应的 key 值来展现例如：
this.form.setFieldsValue(
{pid: this.id}
)个别这种状况会报错，说这个 this.form.setFieldsValue 不是一个 methods，所以能够应用一个定时器
setTimeout()=>{
this.form.setFieldsValue(
{pid : this.id}
),100} 除此之外，还利用了下拉树，在这里能够应用一个树的空间，叫做 <tree-select>
这一简略模块的前端大略就是这个样子。
