}使用
tree组件，使用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，然后把他绑定到要回填的组件上，在这里使用的是:id="this.queryParam.pid"在子组件使用props，在data中定义props：[绑定的key]，这样就收到了，然后使用setFieldsValue回填到子组件表单中需要的位置。
setFieldsValue
在ant 中通过setFieldsValue 存储的类似是一种键值 对的形式，你可以通过对应的key 值来展示例如：
this.form.setFieldsValue(
{
pid: this.id
}
)一般这种情况会报错，说这个this.form.setFieldsValue不是一个methods，所以可以使用一个定时器
setTimeout()=>{
this.form.setFieldsValue(
{
pid : this.id
}
),100}除此之外，还应用了下拉树，在这里可以使用一个树的空间，叫做<tree-select>这一简单模块的前端大概就是这个样子。谢谢
