1.关于vue2 antd 视图更新问题

1.一种强制更新 

Vue2是通过用Object…defineProperty来设置数据的getter和setter实现对数据和以及视图改变的监听的。对于数组和对象这种引用类型来说，getter和setter无法检测到它们内部的变化。用这种

 this.$set(this.form, "fileUrl", urlArr.join(","));

2.如果碰到

a-form :form="form"

 form: this.$form.createForm(this),

    <a-form :form="form" @submit="handleSubmit"><a-form-item:labelCol="labelCol":wrapperCol="wrapperCol"label="上级仓库"hasFeedback><a-tree-select:treeData="dataSource"placeholder="请选择":replaceFields="{title: 'name',key: 'id',value: 'id',children: 'children',}"v-decorator="['parentId', { initialValue: formData.parentId }]"/></a-form-item><a-form-item:labelCol="labelCol":wrapperCol="wrapperCol"label="仓库名称"hasFeedback><a-inputplaceholder="仓库名称"v-decorator="['name',{initialValue: formData.name,rules: validatorRules.inputIf.rules,},]"/></a-form-item><a-form-item:labelCol="labelCol":wrapperCol="wrapperCol"label="所属机构"required><vorganTreev-decorator="['orgId',{initialValue: formData.orgId,rules: validatorRules.inputIf.rules,},]"></vorganTree></a-form-item><a-form-item:labelCol="labelCol":wrapperCol="wrapperCol2"label="位置地点"><div class="disflex"><a-inputv-decorator="['address',{initialValue: formData.address,rules: validatorRules.inputIf.rules,},]"/><a-icon type="environment" @click="mapShow(true)" class="mapico" /><a-button type="link" @click="mapShow(true)">选择地点</a-button></div></a-form-item></a-form>

a-form :form="form"

 form: this.$form.createForm(this),

那么使用

this.form.setFieldsValue({ address: val.address })来更新表单的值，以触发视图的更新。

清空的话

this.form.resetFields();

3.通常双向绑定如果不行试试前两种。

2.关于封装好了表格 使用

1.导入

import STable from "@/components/table/";

index.js

import T from "ant-design-vue/es/table/Table";
import get from "lodash.get"
export default {data() {return {needTotalList: [],selectedRows: [],selectedRowKeys: [],localLoading: false,localDataSource: [],localPagination: Object.assign({}, T.props.pagination)};},props: Object.assign({}, T.props, {rowKey: {type: [String, Function],default: 'id'},data: {type: Function,required: true},pageNum: {type: Number,default: 1},pageSize: {type: Number,default: 10},showSizeChanger: {type: Boolean,default: true},showAlertInfo: {type: Boolean,default: false},showPagination: {default: 'auto'},deleteShow: { // 删除键type: Boolean,default: false},bordered: {type: Boolean,default: true},}),watch: {'localPagination.current'(val) {this.$router.push({name: this.$route.name,params: Object.assign({}, this.$route.params, {current: val}),});},pageNum(val) {Object.assign(this.localPagination, {current: val});},pageSize(val) {Object.assign(this.localPagination, {pageSize: val});},showSizeChanger(val) {Object.assign(this.localPagination, {showSizeChanger: val});}},zzh() {const that = thisreturn that;},created() {this.localPagination = ['auto', true].includes(this.showPagination) && Object.assign({}, this.localPagination, {current: this.pageNum,pageSize: this.pageSize,showSizeChanger: this.showSizeChanger});this.needTotalList = this.initTotalList(this.columns)this.loadData();},methods: {loadingShow(value) {this.localLoading = value},refresh() {var mm = {current: 1,total: 0,size: this.pageSize,}this.loadData(mm);},deleteRefresh() {this.loadData()},loadData(pagination, filters, sorter) {this.localLoading = truevar result = this.data(Object.assign({current: (pagination && pagination.current) ||this.localPagination.current,size: (pagination && pagination.pageSize) ||this.localPagination.pageSize},(sorter && sorter.field && {sortField: sorter.field}) || {},(sorter && sorter.order && {sortOrder: sorter.order}) || {}, {...filters}));if (result instanceof Promise) {result.then(r => {this.localPagination = Object.assign({}, this.localPagination, {current: (pagination && pagination.current) ||this.localPagination.current,  // 返回结果中的当前分页数total: r.totalCount, // 返回结果中的总记录数showSizeChanger: this.showSizeChanger,pageSize: (pagination && pagination.pageSize) ||this.localPagination.pageSize});!r.totalCount && ['auto', false].includes(this.showPagination) && (this.localPagination = false)this.localDataSource = r.data; // 返回结果中的数组数据this.localLoading = false});}},initTotalList(columns) {const totalList = []columns && columns instanceof Array && columns.forEach(column => {if (column.needTotal) {totalList.push({...column,total: 0})}})return totalList},updateSelect(selectedRowKeys, selectedRows) {this.selectedRowKeys = selectedRowKeysthis.selectedRows = selectedRowslet list = this.needTotalListthis.needTotalList = list.map(item => {return {...item,total: selectedRows.reduce((sum, val) => {let total = sum + get(val, item.dataIndex)return isNaN(total) ? 0 : total}, 0)}})},updateEdit() {this.selectedRows = []},onClearSelected() {this.selectedRowKeys = []this.selectedRows = []this.updateSelect([], [])this.$emit('emptyData', { selectedRowKeys: [], selectedRows: [] })this.$emit('onSelect', { selectedRowKeys: [], selectedRows: [] })},onDeleteSelected() {this.$emit('DeleteData')},handleRowClick(record) {const selectedRowKeys = [...this.selectedRowKeys];const selectedRows = [...this.selectedRows];const rowKey = typeof this.rowKey === 'function' ? this.rowKey(record) : record[this.rowKey];const rowIndex = selectedRowKeys.indexOf(rowKey);if (rowIndex >= 0) {selectedRowKeys.splice(rowIndex, 1);selectedRows.splice(rowIndex, 1);} else {selectedRowKeys.push(rowKey);selectedRows.push(record);}this.updateSelect(selectedRowKeys, selectedRows);this.$emit('onSelect', { selectedRowKeys, selectedRows });},renderMsg(h) {const _vm = thisthis.that = thislet d = []return d},renderAlert(h) {return h('span', {slot: 'message'}, this.renderMsg(h))},},render(h) {const _vm = thislet props = {},localKeys = Object.keys(this.$data);Object.keys(T.props).forEach(k => {let localKey = `local${k.substring(0, 1).toUpperCase()}${k.substring(1)}`;if (localKeys.includes(localKey)) {return props[k] = _vm[localKey];}return props[k] = _vm[k];})// 显示信息提示if (this.showAlertInfo) {props.rowSelection = {selectedRowKeys: this.selectedRowKeys,onChange: (selectedRowKeys, selectedRows) => {_vm.updateSelect(selectedRowKeys, selectedRows)_vm.$emit('onSelect', { selectedRowKeys: selectedRowKeys, selectedRows: selectedRows })}};props.customRow = (record) => ({on: {click: () => {_vm.handleRowClick(record);},},});return h('div', {}, [h("a-table", {tag: "component",attrs: props,on: {change: _vm.loadData},scopedSlots: this.$scopedSlots}, this.$slots.default)]);}props.customRow = (record) => ({on: {click: () => {_vm.handleRowClick(record);},},});return h("a-table", {tag: "component",attrs: props,on: {change: _vm.loadData},scopedSlots: this.$scopedSlots}, this.$slots.default);},
};

使用

 <s-tableref="tableAssets"size="default":rowKey="(record) => record.id":columns="columns1":data="loadDataListAssets":showAlertInfo="true"@onSelect="onChangeAssetsList"></s-table>loadDataListAssets: (parameter) => {return getUserPage(Object.assign(parameter, this.listAssetsParam)).then((res) => {var mm = { data: [] };mm.size = res.data.size;mm.current = res.data.current;mm.totalCount = res.data.total;mm.totalPage = res.data.pages;mm.data = res.data.records;return mm;});},onChangeAssetsList(row) {console.log(row);let self = this;self.personList = [];let arr = [...new Set([...row.selectedRows])];let AssetsListRow = [...new Set([...self.AssetsListRow.concat(arr), ...arr]),];self.AssetsListRow = AssetsListRow.filter((item) =>row.selectedRowKeys.includes(item.id));self.personList = [...new Set([...self.AssetsListRow, ...arr])];// self.personList = [...new Set([...self.personList, ...arr])];// const strings = self.personList.map((item) => JSON.stringify(item));// const removeDupList = Array.from(new Set(strings));// const result = removeDupList.map((item) => JSON.parse(item));// self.personList = result;},

有slot使用

 <s-table ref="tableAssets2" size="default" :columns="columns2" :data="loadDataListAssets2"><span slot="action" slot-scope="text, record" class="flx-row-c-c"><div><a @click="handleDel(record)">删除</a></div></span>
</s-table> 

3.关于单选封装好的组件使用

    <j-select-supplierv-decorator="['supplierId']":multiple="false"@accountData="accountData2"></j-select-supplier>import JSelectSupplier from "@/components/jeecgbiz/JSelectSupplier";accountData2(e) {if (e.length > 0) {this.editform.supplierName = e[0].name;this.editform.supplierId = e[0].id;} else {this.editform.supplierName = "";this.editform.supplierId = "";}console.log(e);},

<template><!-- 定义在这里的参数都是不可在外部覆盖的，防止出现问题 --><j-select-biz-component-two:value="value":ellipsisLength="25":listUrl="url.list":columns="columns":multiple="false"v-on="$listeners"v-bind="attrs"@commitData="commitData"/>
</template><script>
import JSelectBizComponentTwo from "./JSelectBizComponentTwo";export default {name: "JSelectSupplier",components: { JSelectBizComponentTwo },props: ["value"],data() {return {url: { list: "/asset/supplierinfo/page" },columns: [{ title: "供应商", align: "center", dataIndex: "name" },{title: "联系人",align: "center",dataIndex: "linkman",},{title: "联系电话",align: "center",dataIndex: "phone",},],// 定义在这里的参数都是可以在外部传递覆盖的，可以更灵活的定制化使用的组件default: {name: "供应商",width: "80%",displayKey: "name",returnKeys: ["id", "name"],rowKey: "id",valueKey: "id",queryParamText: "供应商名称", //左侧搜索框名称queryParamCode: "name", //左侧搜索框字段名},};},computed: {attrs() {return Object.assign(this.default, this.$attrs);},},methods: {// 提交数据commitData(e) {console.log(e);this.$emit("accountData", e);},},
};
</script><style lang="less" scoped></style>

外层也就是index

这边的方法通单选框是一样的

5.关于没有封装的单选框表格同时要实现点击行增加单选框选中效果

 这边表格分页效果是来自JeecgListMixin这个组件或者看5那边有单独写出来分页

7.打印和导出写法

// 打印资产标签列表
const printAssetList = (fileName, params) => downloadFile("/asset/warehousing/printAssetList", fileName, params, "pdf"); // 打印资产标签列表

//导出资产列表
const warehousingExport = (fileName, params) => downloadFile("/asset/assetsinfo/export", fileName, params, "get"); // 导出资产列表

  // 打印资产clickAssetsPrint() {this.assetsPrintLoading = true;var mm = {};mm.id = this.selectedRows.map((item) => {return item.materialCode;});printAssetList("资产标签", mm).then((res) => {this.assetsPrintLoading = false;}).catch((err) => {this.assetsPrintLoading = false;});// this.$refs.barCode.transferData(this.selectedRows)},// 导出资产getWarehousingExport() {var mm = {};mm.id = this.selectedRows.map((item) => {return item.materialCode;});warehousingExport("资产列表", mm).then((res) => {// let execlName = "资产文件名称";// const buf = Buffer.from(res),//   blob = new Blob([buf], { type: "application/vnd.ms-excel" }),//   downloadElement = document.createElement('a'),//   href = window.URL.createObjectURL(blob); // 创建下载的链接// downloadElement.href = href;// downloadElement.download = `${execlName}.xls`; // 下载后文件名// document.body.appendChild(downloadElement);// downloadElement.click(); // 点击下载// window.URL.revokeObjectURL(href); // 释放掉blob对象});},

8.显示已删除的供应商

<a-checkboxstyle="margin-left: 20px"@change="onChange":value="yesOfno">显示已删除的供应商</a-checkbox>

    onChange(e) {this.yesOfno = e.target.checked;this.$refs.table.refresh(this.queryParam);},

    <s-tableref="table"size="default":columns="columns":data="loadData"@onSelect="onChangeTableSelect"><span slot="action" slot-scope="text, record"><a @click="handleEdit(record)">编辑</a><a-divider type="vertical" /><a-popconfirm title="你确定要删除吗？" @confirm="deleteTable(record)"><a>删除</a></a-popconfirm></span></s-table>

    refresh() {var mm = {current: 1,total: 0,size: this.pageSize,}this.loadData(mm);},

 同时也有关于loadData传参查询

   // 加载数据方法 必须为 Promise 对象loadData: (parameter) => {this.queryParam.delFlag = this.yesOfno ? 1 : "";return listSupplierinfo(Object.assign(parameter, this.queryParam)).then((res) => {console.log(res);var mm = { data: [] };mm.size = res.data.size;mm.current = res.data.current;mm.totalCount = res.data.total;mm.totalPage = res.data.pages;mm.data = res.data.records;return mm;});},

9.关于loadData传参查询

  loadData: (parameter) => {return allotapplyPage(Object.assign(parameter, this.queryParam)).then((res) => {var mm = { data: [] };mm.size = res.data.size;mm.current = res.data.current;mm.totalCount = res.data.total;mm.totalPage = res.data.pages;mm.data = res.data.records;return mm;});},
