时间戳例子：

<div class="block"><el-timeline><el-timeline-item timestamp="2018/4/12" placement="top"><el-card><h4>更新 Github 模板</h4><p>王小虎 提交于 2018/4/12 20:46</p></el-card></el-timeline-item><el-timeline-item timestamp="2018/4/3" placement="top"><el-card><h4>更新 Github 模板</h4><p>王小虎 提交于 2018/4/3 20:46</p></el-card></el-timeline-item><el-timeline-item timestamp="2018/4/2" placement="top"><el-card><h4>更新 Github 模板</h4><p>王小虎 提交于 2018/4/2 20:46</p></el-card></el-timeline-item></el-timeline>
</div>

前端：

加入按钮 抽屉  抽屉内直接写内容样式  调用值

       <el-buttonsize="mini"type="text"icon="el-icon-view"@click="showDrawer(scope.row)"v-hasPermi="['enforceLaw:caseParamsLog:list']">查看历史记录</el-button><el-drawer:visible.sync="drawerVisible":direction="drawerDirection":before-close="handleClose"append-to-body><div slot="title" v-for="(log, index) in logList" :key="index"><h4 v-if="index === 0">{{ log.paramsKey }}<dict-tag :options="dict.type.case_params_key" :value="logList[0].paramsKey"/></h4></div><div class="log-item" v-for="(log, index) in sortedLogList" :key="index"><el-timeline><el-timeline-item placement="top"><el-card><p>创建人：{{ log.createBy }} 创建于 {{ log.createTime }}</p><p>变更位置：{{ log.changeLocation }}</p><p>旧值：{{ log.oldParamsValue }}</p><p>新值：{{ log.newParamsValue }}</p></el-card></el-timeline-item></el-timeline></div></el-drawer>

需要的方法/数据

    showDrawer(row) {const caseId = row.caseId;const paramsKey = row.paramsKey;listCaseParamsLog({caseId:caseId,paramsKey:paramsKey}).then(response => {this.logList = response.rows;this.loading = false;this.drawerContent = this.logList; // 将日志列表赋值给drawerContentthis.drawerVisible = true; // 打开抽屉});},data() {return {drawerVisible: false,drawerDirection: "ltr",drawerTitle: "", // variable to store the drawer title// 遮罩层loading: true,//可选项列表dataList: [],logList: [],computed: {row() {return row},sortedLogList() {return this.logList.sort((a, b) => new Date(b.createTime).getTime() - new Date(a.createTime).getTime());}},

后端：

   /*** 获取案源参数变更日志详细信息*/@PreAuthorize("@ss.hasPermi('enforceLaw:caseParamsLog:query')")@GetMapping(value = "/{changeId}")public AjaxResult getInfo(@PathVariable("changeId") Long changeId){return success(lawCaseParamsLogService.selectLawCaseParamsLogByChangeId(changeId));}<select id="selectLawCaseParamsLogByChangeId" parameterType="Long" resultMap="LawCaseParamsLogResult"><include refid="selectLawCaseParamsLogVo"/>where change_id = #{changeId}</select>
