这篇文章主要为大家详细介绍了vue+iview Table表格多选切换分页保持勾选状态,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
本文实例为大家分享了vue+iview Table表格多选切换分页保持勾选状态的具体代码,供大家参考,具体内容如下
第一种情况(配合后端做选中数据处理)
定义三个参数,是否为全选(isSelectAll)、不是全选时选择的数据(selectObject: [])、反选数据(unSelectObject:[])
HTML
<Alert show-icon v-show="openTip"> 已选择 <span class="select-count" v-if="isSelectAll">{{ total-unSelectObject.length }}</span> 项 <span class="select-count" v-if="!isSelectAll">{{ selectObject.length }}</span> 项 <a class="select-clear" @click="clearSelectAll">清空</a> <span class="button"> <Button @click="onSelectAll" type="primary">全选</Button> </span> <span class="button"> <Button @click="selectAllcancel" type="primary">取消全选</Button> </span> </Alert> <Table :loading="loading" border :columns="columns" :data="data" @on-select-all="selectAll" @on-select-all-cancel="cancelAll" @on-select="TableSelectRow" @on-select-cancel="TableSelectCancelRow" > </Table> <Row type="flex" justify="end" class="page"> <Page :current="searchForm.pageIndex" :total="total" :page-size="searchForm.pageSize" @on-change="changePage" @on-page-size-change="changePageSize" :page-size-opts="[10, 20, 50]" size="small" show-total show-elevator show-sizer ></Page> </Row>
data
data: [], isSelectAll: false, condition: '', selectObject: [], unSelectObject: [], selectEquipsIds: '0',
JS
// 全选 onSelectAll() { this.isSelectAll = true this.getDataList() }, //取消全选 selectAllcancel() { this.isSelectAll = false this.selectEquipsIds = '0' this.getDataList() }, //全选当前页 selectAll() { if (this.isSelectAll) { for (let i = this.data.length - 1; i >= 0; i--) { var _index = this.unSelectObject.indexOf(this.data[i].id) if (_index != -1) { this.unSelectObject.splice(_index, 1) } } console.log(this.unSelectObject) } else { for (let i = this.data.length - 1; i >= 0; i--) { this.selectObject.push(this.data[i].id) } console.log(this.selectObject) } }, // 取消当前页 cancelAll() { if (this.isSelectAll) { for (let i = this.data.length - 1; i >= 0; i--) { this.unSelectObject.push(this.data[i].id) } console.log(this.unSelectObject) } else { for (let i = this.data.length - 1; i >= 0; i--) { var _index = this.selectObject.indexOf(this.data[i].id) if (_index != -1) { this.selectObject.splice(_index, 1) } } console.log(this.selectObject) } }, // 选中一行 TableSelectRow(selection, row) { if (this.isSelectAll) { var _index = this.unSelectObject.indexOf(row.id) if (_index != -1) { this.unSelectObject.splice(_index, 1) console.log(this.unSelectObject) } } else { if (!this.selectObject.includes(row.id)) { this.selectObject.push(row.id) console.log(this.selectObject) } } }, // 取消选中一行 TableSelectCancelRow(selection, row) { if (this.isSelectAll) { this.unSelectObject.push(row.id) } else { var _index = this.selectObject.indexOf(row.id) if (_index != -1) { this.selectObject.splice(_index, 1) console.log(this.selectObject) } } }, // 判断是否选中 sortData() { if (this.isSelectAll) { for (let i = this.data.length - 1; i >= 0; i--) { if (!this.unSelectObject.includes(this.data[i].id)) { this.data[i]._checked = true } } } else { if (this.selectObject.length) { this.data.forEach((ele) => { if (this.selectObject.includes(ele.id)) ele._checked = true }) } } }, getDataList() { // 多条件搜索用户列表 this.loading = true api().then((res) => { this.loading = false if (res.success) { this.data = res.result?.records this.sortData() //分页时保留选中状态 if (this.data.length == 0 && this.searchForm.pageIndex > 1) { this.searchForm.pageIndex -= 1 this.getDataList() } } }) },
实现效果
全选效果
单独选择效果
整页全选选择效果
整页全选+单选
第二种情况(只给后端传需要传的数据)
定义一个参数,已选数据(selectObject:[])
HTML
<div class="table-div"> <Table :columns="columns" :data="tableList" @on-select-all="selectAll" @on-select-all-cancel="cancelAll" @on-select="TableSelectRow" @on-select-cancel="TableSelectCancelRow" /> </div> <Row type="flex" justify="end" class="page"> <Page :current="searchForm.pageIndex" :total="total" :page-size="searchForm.pageSize" @on-change="changePage" @on-page-size-change="changePageSize" :page-size-opts="[10, 20, 50]" size="small" show-total show-elevator show-sizer ></Page> </Row>
data
data: [], selectObject: [],
JS
//判断是否选中 sortData() { if (this.selectEquipsIds.length) { this.tableList.forEach(ele => { if (this.selectEquipsIds.includes(ele.id)) ele._checked = true; }) } }, // 选中一行 TableSelectRow(selection, row) { if (!this.selectEquipsIds.includes(row.id)) { this.selectEquipsIds.push(row.id); } }, // 取消选中一行 TableSelectCancelRow(selection, row) { var _index = this.selectEquipsIds.indexOf(row.id); if (_index != -1) { this.selectEquipsIds.splice(_index, 1); } }, // 选中所有 selectAll() { for (let i = this.tableList.length - 1; i >= 0; i--) { this.TableSelectRow(null, this.tableList[i]); } }, // 取消选中所有 cancelAll() { for (let i = this.tableList.length - 1; i >= 0; i--) { this.TableSelectCancelRow(null, this.tableList[i]); } }, // 翻页查询 onChange(param) { this.page.PageIndex = param; this.getDataList(); }, // 选择分页数 onPageSizeChange(param) { this.page.PageSize = param; this.getDataList(); }, // 查询表格数据 getDataList() { // 多条件搜索用户列表 this.loading = true api().then((res) => { this.loading = false if (res.success) { this.data = res.result?.records this.sortData() // this.total = res.result.total if (this.data.length == 0 && this.searchForm.pageIndex > 1) { this.searchForm.pageIndex -= 1 this.getDataList() } } }) }, },
以上均已实测可用。
