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-input
placeholder="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
>
<vorganTree
v-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-input
v-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,

},
}),
watch: {
'localPagination.current'(val) {
this.$router.push({

}),
});
},
pageNum(val) {
Object.assign(this.localPagination, {

},
pageSize(val) {
Object.assign(this.localPagination, {
pageSize: val
});
},
showSizeChanger(val) {
Object.assign(this.localPagination, {

}
},
zzh() {
const that = this
return 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 = true
var 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 = selectedRowKeys
this.selectedRows = selectedRows
let list = this.needTotalList
this.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 = this
this.that = this
let d = []
return d
},
renderAlert(h) {
return h('span', {
slot: 'message'
}, this.renderMsg(h))
},
},
render(h) {
const _vm = this
let 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-table
ref="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-supplier
v-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"

</template>
<script>

],

default: {

},
};
},
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

* 高级查询按钮调用 superQuery方法 高级查询组件ref定义为superQueryModal
* data中url定义 list为查询列表 delete为删除单条记录 deleteBatch为批量删除

// this.$refs.barCode.transferData(this.selectedRows)
},
// 导出资产

// 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
