问题
如何给列表数据打标签？类似下面这种样子?
思路 实现
- 数模转换（对接口请求回来的数据进行过滤标记，返回新的数据）
- 渲染新的数据模型
1、过滤数据，需要打标签的采用jsx写法
业务数据的处理我封装在 mixins 里面
// 存放全局的mixin， 可拆分到模块独享
import { mapGetters } from 'vuex'
import { fetchListData } from '@/api/global/api.js'
export default {
data() {
return {
p_category: [],
listdata: [],
p_total: 0,
p_loading: false,
}
},
computed: {
// ...mapGetters(['productLevel', 'productLevelInfo']),
p_listdata() {
const data = this.listdata;
data.forEach((item) => {
// ...
// jsx 方式，打标签
if (item.status === 2 || item.status === 3) {
item.status = <span style={{color: '#999'}}>停售</span>
} else {
item.status = item.status
}
if (item.age <= 25) {
item.age = <span class="badge_info">{item.age}</span>
}
if (item.sex === 'Man') {
item.sex = <span class="badge_default">{item.sex}</span>
}
})
return data;
}
},
methods: {
async getProductList(params = {}) {
try {
this.p_loading = true
this.listdata = []
const res = await fetchListData(params)
if (res.code === 0) {
const { data = [], total = 0 } = res || {}
if (Array.isArray(data)) {
this.listdata = [...data]
this.p_total = total
} else {
this.listdata = []
this.p_total = 0
}
} else {
this.listdata = []
this.p_total = 0
this.$message.error(res.message || '出错了')
}
this.p_loading = false;
} catch (err) {
this.p_loading = false
this.listdata = []
this.p_total = 0
console.log(err);
}
}
}
}
base.less 定义标签样式
.badge_info {
color: #4760f0;
background: #1C84C6;
padding: 5px 8px;
color: #fff;
border-radius: 5px;
}
.badge_default {
color: #4760f0;
background: #4760f0;
padding: 5px 8px;
color: #fff;
border-radius: 5px;
}
2、封装列表渲染组件
<template>
<ul class="listV2">
<li class="listV2_row-title">
<span v-for="(col, index) in fieldList" :key="index" class="listV2_cell ellipsis" :name="col.fieldName">
{{col.fieldLabel}}
</span>
</li>
<!-- 行 -->
<div v-if="tableData.length === 0" class="nodata">暂无数据</div>
<li v-for="(row, index) in tableData" :key="index" class="listV2_row pointer" @click="rowClickToDetail(row)">
<!-- 单元格-列 -->
<span v-for="(col, index) in fieldList" :key="index" class="listV2_cell ellipsis" :name="col.fieldName">
<RenderDom :vNode="row[col.fieldName] || '-'"></RenderDom>
</span>
</li>
</ul>
</template>
<script>
import RenderDom from "./renderDom";
export default {
name: 'TableList',
props: {
tableData: {
type: Array,
required: true,
},
fieldList: {
type: Array,
required: true,
},
align: {
type: String,
default: 'left',
},
},
components: {
RenderDom,
},
data() {
return {}
},
computed: {},
watch: {},
created() { },
mounted() { },
methods: {},
updated() { },
beforeDestroy() { },
}
</script>
<style lang='less' rel='stylesheet/less' scoped>
@import "./index.less";
</style>
3、封装渲染vNode的方法
const renderDom = {
props: {
vNode: {
type: [Array, String, Object,Number],
},
},
render(h) {
// jsx - vNode 直接返回，交给框架处理（js语法带来很多可能，列表打标签功能）
if (typeof this.vNode === 'object') {
return this.vNode;
}
// 普通数据，直接包一层div，然后返回给页面
return h(
'div',
{
class: 'ellipsis',
},
this.vNode
)
}
}
4、页面组件调用
<template>
<div class="customer">
<table-list v-loading="p_loading" :tableData="p_listdata" :fieldList="fieldList"></table-list>
</div>
</template>
<script>
import TableList from '@/basecomponents/TableList/index'
import $_pMixins from "@/mixins/product.js";
import enums from './enum.js'
export default {
name: 'Customer',
props: {},
components: {
'table-list': TableList,
},
mixins: [$_pMixins],
data() {
return {
tableData: [],
fieldList: Object.freeze(enums.Enum_customerFieldList),
}
},
computed: {},
watch: {},
created() {
},
mounted() {
this.initData()
},
methods: {
initData() {
this.getProductList()
}
},
updated() { },
beforeDestroy() { },
}
</script>
<style lang='less' rel='stylesheet/less' scoped>
@import "./index.less";
</style>
效果展示
以上就是使用vNode实现给列表字段打标签的详细内容，更多关于vNode列表字段标签的资料请关注编程网其它相关文章！
