iView的Table组件
前端在多选时如果点击下一页则丢失了上一页Table的多选数据(由于采用的后端分页,每次翻页会直接刷新为新数据)
定义变量
loading: false, columnsData: [], //表格表头 talbeData: [], //表格数据 params: { total: 0, page: 1, limit: 10 },//请求参数 selectedData: [],//选中的数据 defSelectData: [] // 去重数据
页面实现
<Table border stripe ref="table" :loading="loading" :columns="columnsData" :data="talbeData" @on-select="onSelectAll" @on-select-cancel='onSelectCancel' @on-select-all="onSelectAll" @on-select-all-cancel='onSelectAllCancel'></Table> <Page :total="params.total" :current="params.page" :page-size="limit" @on-change="changePage" @on-page-size-change="changeSize" show-elevator show-sizer show-total></Page>
表格点击触发
// 全选 触发 onSelectAll(selection) { // 去重之前的 选中后合并的数组 this.defSelectData = [...selection, ...this.defSelectData] for (let val of this.defSelectData) { if (!this.selectedData.some(item => item.ID === val.ID)) { this.selectedData.push(val) } } }, // 取消选中 时触发 onSelectCancel(selection, row) { let result = this.selectedData.findIndex((el) => { return el.ID === row.ID }) this.selectedData.splice(result, 1) }, // 取消全选 触发 onSelectAllCancel() { this.selectedData = this.selectedData.filter(item => { return this.talbeData.every(el => { return item.ID !== el.ID }) }) },
点击分页,取到新一页的数据,进行选中回显
// 获取数据 getTableData() { this.loading = true getDepUserList(this.params).then(res => { this.loading = false let data = res.data data.list.forEach(item => { //选中数据回显 this.$set(item, '_checked', this.selectedData.some(el => el.ID === item.ID)); }); this.params.total = data.count this.talbeData = data.list }) }, changePage(page) { this.params.page = page this.getTableData() }, changeSizeMember(size) { this.params.limit = size this.getTableData() },标签:el,分页,回显,item,选中,Table,data,ID,selectedData From: https://www.cnblogs.com/yj-ang3141/p/18435371
