vue 函数组件解决动态渲染问题

1. 场景： 有一个检索池，检索条件可以自定义一个，检索条件对应的数据动态加载，检索条件对应的项不确定，有 sleect,input, dateRabge....

 2. 需求遇到的问题

　　1. 方案1： 使用 v-html 解决，1. 不能解决数据动态加载问题，2. 不能解决项目是 innput select 动态的问题

　　2. 方案2：使用render方法，函数组件动态渲染

3. 解决步骤：

　　1. 定义条件枚举：

2. 定义渲染函数组件

export default {
  name: 'searchItems',
  functional: true,
  props: {
    render: Function,
    index: Number,
    type: String,
    relationShipName: String
  },
  render: (h, ctx) => {
    const params = {
      index: ctx.props.index,
      relationShipName: ctx.props.relationShipName,
      type: ctx.props.type
    }
    return ctx.props.render(h, params)
  }
}
