表单组件二次封装（vue-elementui、搜索条件）

搜索条件组件

(SearchForm\index.vue放在目录的components下)：

<template>

父组件中引入

html部分：

 <search-form class="searchMain" size="mini" label-width="80px" :search-data="searchData" :search-form="searchForm" :search-handle="searchHandle" />
          

js部分：

import SearchForm from '@/components/SearchForm'
export default {
  components: {  SearchForm },
  data() {
    return {
	    searchData: { // 查询参数
	        pageNum: 1, pageSize: 5, userId: undefined, buildingId: undefined, communityId: undefined,
	        merchantId: undefined, roomNo: undefined, unitId: undefined,
	        data: { mobilePhone: undefined, residentName: undefined }
	    },
	    searchForm: [
	        { type: 'Input', label: '室', prop: 'roomNo', width: '100px', placeholder: '请输入室...' },
	        { type: 'Input', label: '姓名', prop: 'residentName', width: '100px', placeholder: '请输入姓名...' },
	        { type: 'Input', label: '手机号', prop: 'mobilePhone', width: '100px', placeholder: '请输入手机号码...' }
	    ],
	    searchHandle: [
	        { label: '查询', type: 'primary', handle: this.getList },
	        { label: '重置', type: 'primary', handle: this.resetForm }
	    ],
    }
  },
  methods:{
  // 获取小区列表、表格信息
    getList() {
      this.loadingTable = true
      this.searchData.userId = this.$store.getters.id
      this.searchData.data.mobilePhone = this.searchData.mobilePhone
      this.searchData.data.residentName = this.searchData.residentName

      listResident(this.searchData).then((response) => {
        const row = response.data.rows || []
        this.list = row.map(function(val) {
          val.identity = val.residentIdentity
          if (val.residentIdentity !== undefined) {
            val.residentIdentity = val.residentIdentity + 0 === 1 ? '住户' : '租户'
          }
          return val
        })
        this.total = response.data.total
        this.loadingTable = false
        this.loading = false
      })
    },
    // 表格重置
    resetForm() {
      Object.assign(this.$data.searchData, this.$options.data().searchData)
    }
  }
}

css部分

.searchMain {
    height: 100px;
 }

（提示：searchData里面不需要的自行删掉，方法和api也是自己写合适的）
