接下来根据传入的参数组装成查询条件 searchWhere，然后通过 HTTP GET 请求获取数据，并将获取到的数据赋值给 dataList、total、pageSize 和 totalPage 等变量。最后根据 pageSize 计算出 pageSizes 数组，并返回...

Object.assign(this.$data, this.$options.data())

通过调用Object.assign方法，可以将$options.data()返回的数据合并到this.$data中，实现数据的初始化或更新。这样做的目的是为了确保组件实例在创建时能够正确地初始化数据，并且在需要时能够动态更新数据。

= Object.assign({}, rowData) this.getMbsj() }) }, getTarget() { if (this.formList.indexName == null || this.formList.indexName == '') { this.$message('请选择分项') return false } if (this.itemize == null || this.itemize == '') { this.$message('请选择总量') return false } this.$ajax({ url: '/lims/projectLib/project_item', method: 'post', data: { name: this.formList.indexName, tableData: this.selectedData, }, }).then(res => { if (res.data.code === 200) { this.$message({ message: '添加成功', center: true, type: 'success', }) this.dialogEdittVisible = false this.getList() } else { this.$message({ message: res.data.msg, center: true, type: 'error', }) this.dialogEdittVisible = false } }) },点击编辑按钮时如何显示编辑之前的数据

如果你想在点击编辑按钮时显示编辑之前的数据，可以在打开编辑对话框之前将要编辑的数据存储到一个变量中，然后在编辑对话框中将这些数据显示出来。具体操作如下： ...}).then(res => { // ... })

save(key) { Object.assign(this.dataSource.filter((item) => key === item.key)[0], this.editableData[key]) this.$set(this.editableData, key, null) // console.log(this.dataSource); },实现保存全部

const item = this.dataSource.filter((item) => key === item.key)[0]; Object.assign(item, this.editableData[key]); this.$set(this.editableData, key, null); } } 这个方法会遍历 this.editableData...

用layui根据以下代码写分页功能 public function index(){ $data = []; //数据总数 $map = []; $status = input('status'); if($status){ $map['status'] = $status; } $typeId = input('typeId'); if($typeId){ $map['typeId'] = $typeId; } $page = input('page',1); $pageSize = input('pageSize',2); $list = AboutuslistMod::field('*')->where($map)->paginate($pageSize,false,['query' => request()->param()]); if(!empty($list)){ $list = $list->toArray(); $total = $list['total']; $data = $list['data']; } unset($list); $typeList = AboutuslistMod::getType(); if(!empty($data)){ $returnData = [ 'code' => 0, 'count' => $total, 'page' => $page, 'pageSize' => $pageSize, 'data' => $data, ]; $data=json(['code'=>0,'msg'=>'获取数据成功!','count'=>$total,'data'=>$data]); } $this->assign([ 'page' => $page, 'pageSize' => $pageSize, "total"=> $total, "list"=> $data, "typeList" => $typeList, // "pages"=> $list->render() ]); return $this->fetch(); }

然后通过Object.assign()方法，将当前行的数据赋值到formEdit对象中，以便在弹窗中渲染出当前行的数据。最后会调用getMbsj方法，获取一些必要的数据。因此，在弹窗中显示当前行数据的代码应该是在<template...

Object.assign(params, this.query)

对于您的代码片段 Object.assign(params, this.query)，这是一种将 this.query 对象的属性合并到 params 对象中的常用方法。使用 Object.assign() 可以将一个或多个源对象的属性复制到目标对象中，并返回...

let params = Object.assign({}, datas.researchInfoForm)

这段代码是用来复制datas.researchInfoForm对象的...Object.assign()方法用于将一个或多个源对象的属性复制到目标对象中，并返回目标对象。在这里，params对象将拥有与datas.researchInfoForm相同的属性和值。

优化这段代码：import { reactive, toRaw } from 'vue' // 分页钩子函数 interface Options { page?: number size?: number fetchFun: (_arg: any) => Promise<any> params?: Record<any, any> firstLoading?: boolean } export function usePaging(options: Options) { const { page = 1, size = 15, fetchFun, params = {}, firstLoading = false } = options // 记录分页初始参数 const paramsInit: Record<any, any> = Object.assign({}, toRaw(params)) // 分页数据 const pager = reactive({ page, size, loading: firstLoading, count: 0, lists: [] as any[], extend: {} as Record<string, any> }) // 请求分页接口 const getLists = () => { pager.loading = true return fetchFun({ page_no: pager.page, page_size: pager.size, ...params }) .then((res: any) => { pager.count = res?.count pager.lists = res?.lists pager.extend = res?.extend return Promise.resolve(res) }) .catch((err: any) => { return Promise.reject(err) }) .finally(() => { pager.loading = false }) } // 重置为第一页 const resetPage = () => { pager.page = 1 getLists() } // 重置参数 const resetParams = () => { Object.keys(paramsInit).forEach((item) => { params[item] = paramsInit[item] }) getLists() } return { pager, getLists, resetParams, resetPage } }

Object.assign(params, paramsInit) getLists() } return { pager, getLists, resetParams, resetPage } } 优化的部分包括： 1. 使用 async/await 替代 Promise.then() 语法，使代码更加简洁易读，同时...
