前言：本次的文章完全是自己开发中遇到的一些问题，经过不断的修改终于完成的一些功能，当个快捷的查看手册吧~
elementui开发后台管理系统常用功能
高级筛选的封装
功能描述：数据使用的若依的字典，或者是自定义数据，可以点击每个选项进行选择，取消选择，也可以在已选择进行清除和单个删除
javascript

configList: [
{
label: "人员性质", // 显示的名称
data: [], // 显示的名称
type: "dict", // 类型：默认 字典 输入框
dict: "personnel_nature", // 如果是字典需要写
isMultiple: true, // 是不是多选
field: "staffType" // 需要给后端传递的字段名称
},
{
label: "年龄",
type: "default",
data: [
{
label: "20岁以下",
value: "0 and 20",
},
{

</script>elementui的表格
- @selection-change 表格前面的select选择
- :show-overflow-tooltip="true" 表格显示内容非常多，可以...省略
- slot-scope="scope" 如果相对内容进行自定义展示可以使用默认插槽
- 序号我们需求是分页序号要递增
html
<el-table v-loading="loading" :data="绑定data数据-数组类型" @selection-change="handleSelectionChange">
<el-table-column type="selection" width="55" align="center" />
<el-table-column label="序号" type="index" width="50" align="center">

</el-table>elementui的表格实现跨页多选+回显
- officeBuildingList 绑定的表格数据
@selection-change="handleOfficeSelect"选择的方法:row-key="getKey"唯一标识:reserve-selection="true"
javascript
<el-table class="my-table" :data="officeBuildingList" @selection-change="handleOfficeSelect" ref="trainCourseTable" :row-key="getKey">
<el-table-column type="selection" width="55" align="center" :reserve-selection="true" />
<el-table-column label="数据" align="center" prop="字段" width="120" />
</el-table>
methods: {
// 编辑情况回显数据：
// 1. 因为是分页，简单做法就是一开始在create中调用获取全部的数据 pageSize：9999
listOfficeBuilding({pageNum: 1,pageSize: 9999}).then((res) => {
// 拿到form表单字段中的数据，在所有的数据中筛选
if (this.form.字段名称) {
const arr = this.form.字段名称.split(",")
res.rows.forEach(item => {
if (arr.includes(item.字段名称) && !this.suppliesMultipleList.includes(item)) {
this.suppliesMultipleList.push(item)
}
})
}
});
// 2. 打开弹窗调用接口获取表格数据，判断有字段并且是编辑状态才需要回显
if (this.form.字段名称 && this.form.id) {
this.$nextTick(() => {
// 把筛选好的
this.suppliesMultipleList.forEach(row => {
this.$refs.trainCourseTable.toggleRowSelection(row, true)
})
})
}
}
// 点击表格前的复选框保存数据
handleOfficeSelect(val) {
this.suppliesMultipleList = val
},
getKey(row) {

},elementui的表单
elementui的日历

</el-calendar>这个是缩小以后的效果，为了截取全部，点击日期可以切换。我们这里的放假上班在系统有菜单进行单独配置，通过接口拿到数据和日历的日期进行匹配展示文字
vue获取某几天内的日期和星期几
javascript
