动态循环加载组件
1，需求场景：

如上图的弹框的搜索筛选条件：每一项的都是一个组件，通过动态遍历加载出来，而且右边可以控制每一项的排序以及是否显示隐藏在外面

直接上代码：
因为筛选搜索条件是每个选项卡都需要的，所以就把筛选搜索条件放在每个选项卡上面公用，同时筛选搜索条件放在一个组件里遍历
-父组件部分-
<div>
<el-tabs v-model="reminderVEnums" @tab-click="handleClick">
<!--高级搜索子组件-->
<advancedSearch
style="margin:20px 0 30px 0"
:filter.sync="filter"
:reminderVEnums.sync="reminderVEnums"
v-show="reminderVEnums!='rework'" <!--因为上面"开发票选项卡"不需显示，所以这里判断一下-->
ref="advancedSearch">
</advancedSearch>
<!-- 第一个选项卡开始 -->
<el-tab-pane :label="'待发货订单（'+NEW_ORDER+'）'" name="NEW_ORDER">
<!-- 选项卡子组件-->
<remindertable:orderList="orderList"></remindertable>
</el-tab-pane>
<!-- 第一个选项卡结束 -->
<!--后面的选项卡就不放出来了-->
</el-tabs>
</div>
<script lang="ts">
import Vue from "vue";
import Component from "vue-class-component";
import remindertable from "./remindertable";//选项卡子组件
import advancedSearch from "./components/advancedSearch";//高级搜索子组件
@Component({
props: {},
components: { //注册组件
remindertable,
advancedSearch
}
})
export default class AfterOrder extends Vue {
reminderVEnums = "NEW_ORDER";//选项卡默认选中待发货
//高级搜索的初始值
filter = {
rderStatus: "ORDER_WAIT_SENDGOODS", //默认页面加载待发货状态选项卡
paymentMode: "", //支付方式
preDrugType: [""], //处方类型
patientKeyword: null, //医院信息关键字
hospitalKeyword: null, //患者信息关键字
consigneeKeyword: null, //收件信息关键字
prescriptionOrderKeyword: null, //订单处方关键字
minPrice: null,
maxPrice: null,
orderTime: [] //时间
};
//切换选项卡就初始化filter
handleClick(tab, e) {
this.filter.rderStatus = "";
this.filter.paymentMode = "";
this.filter.orderTime = [""];
this.filter.preDrugType = [""];
this.filter.patientKeyword = null;
this.filter.hospitalKeyword = null;
this.filter.consigneeKeyword = null;
this.filter.prescriptionOrderKeyword = null;
}
}
</script>
这里看看组件的目录结构

-子组件部分开始-
<template>
<div>
<el-form label-width="80px" :inline="true" class="demo-form-inline">

<el-button

-以下是每一项的筛选条件（相当于孙组件）-
这里就上传一项的筛选条件组件代码，其他也是一样的，只是每一个筛选条件放在一个组件即可
