1.vue代码
<template> <el-table @selection-change="handleSelectionChange" @sort-change="sortChange" v-loading="loading" id = "TableColumnID" element-loading-text="加载中..." :data="listData.List" highlight-current-row style=" 100%;"> <el-table-column type="selection" width="55"></el-table-column> <el-table-column width="80" prop="UserName" label="登录名" :show-overflow-tooltip="true" sortable="custom"></el-table-column> <el-table-column width="80" prop="byName" label="姓名" :show-overflow-tooltip="true" sortable="custom"></el-table-column> <el-table-column :formatter="roleType" prop="Role" label="用户权限" :show-overflow-tooltip="true" sortable="custom" width="150"></el-table-column> <el-table-column prop="LastActivityTime" label="更新时间" sortable="custom" width="200"></el-table-column> <el-table-column prop="CreateTime" label="创建时间" sortable="custom" width="200"></el-table-column> <el-table-column fixed="right" label="操作" align="center"> <template slot-scope="scope"> <el-button type="primary" size="small" @click="handleEdit(scope.row)">编辑</el-button> <el-button type="danger" size="small" @click="handleDelete(scope.row)">删除</el-button> </template> </el-table-column> </el-table> </template>
2.sort-change事件分析
如果需要后端实现排序功能,需要将sortable设置为custom,同时在 Table 上监听sort-change事件,在事件回调中可以获取当前排序的字段名和排序顺序,从而向接口请求排序后的表格数据。
sort-change方法自带三个参数,分别代表意义是:
column:当前列
prop:当前列需要排序的数据
order:排序的规则(升序、降序和默认[默认就是没排序])
3.JS代码:
data() { return { loading: false, listData: [], addVisible: false, currentObj: { U: {}, UAccount: {} }, queryData: { UserName: "", CustomerCode: "", CustomerName: "", role: 0, p_Role: "", prop : "", order : "", currentPage: 1, pageSize: 10 }, EUserP_Role: [], p_Role: {}, ids: [] }; }, methods: { sortChange(column,prop,order){ if(column.prop == null || column.order == null){ this.queryData.prop = ""; this.queryData.order = ""; }else{ this.queryData.prop = column.prop; this.queryData.order = column.order; } this.getList(); }, getList() { this.loading = true; this.$API.User.List(this.queryData).then(res => { this.loading = false; this.listData = res; this.currentPage = 1; this.prop = column.prop; this.order = column.order; }); }
