Vue之element table 后端排序实现
1、如果需要后端排序,需将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。
<el-table @sort-change='tableSortChange'>
<el-table-column sortable='custom' prop="createTime" label="创建时间">
</el-table-column>
</el-table>
2、定义methods监听sort-change事件
tableSortChange(column) {
this.listQuery.pageNo = 1
if (column.order === 'descending') {
this.listQuery.sortby = column.prop
this.listQuery.order = 'desc'
} else {
this.listQuery.sortby = column.prop
this.listQuery.order = 'asc'
}
this.getList()
}
3、通过axios提交请求数据到后端
getList() {
this.listLoading = true
fetchList(this.listQuery).then(response => {
this.list = response.data.items
this.total = response.data.total
this.listLoading = false
})
}
