2024问题总结

news/2025/2/12 14:05:07/文章来源:https://www.cnblogs.com/hellofangfang/p/18711457

20241225 XlVirtualList解决数据量大,滚动后,再点下拉会出现空白

setTimeout(() => {

document.querySelector('.vxe-table--body').style.marginTop = 0

})

20241224双向数据绑定问题

加key
是否已有这个元素
$set
慢半拍加$nextTick

:key="isPlan?scope.row.dblamount:null"

有结算计划时只能输入一个字就会失去焦点

20241213vue中Import加{}和不加{}，有什么区别？

默认导出（default export）每个模块可以有一个默认导出，它可以是一个变量、函数或组件。当你导入默认导出时，不需要使用大括号{}

// MyComponent.js
export default function MyComponent() {
// ...
}

// App.js
import MyComponent from './MyComponent';

命名导出（named export）：一个模块可以有多个命名导出。当你导入命名导出时，需要使用大括号{}。

// utils.js
export function funcA() {
// ...
}

export function funcB() {
// ...
}

// App.js
import { funcA, funcB } from './utils';

20211203 scoped样式穿透

.menu-wrapper /deep/ .el-submenu__title

</style>

20241128 PinyinMatch

思路一：

computed: {

filterList() {

if (this.fieldtypesearch.length) {

return this.detailList.filter(val => {

return PinyinMatch.match(val.strdicttypecodeandname, this.fieldtypesearch)

})

} else {

return this.detailList

}

思路二：

<el-input

slot="reference"

v-model="currVal"

placeholder="请输入"

maxlength="250"

clearable

@change="changeEvent"

@input="inputEvent"

@focus="focusEvent"

inputEvent(val) {

if (val) {

this.employeesList = this.copyList.filter((item) => {

return PinyinMatch.match(item.strfullname, val)

})

} else {

this.employeesList = this.copyList

}

20241113 提取后缀.ofd

function checkFile(fileValue) {

var index = fileValue.lastIndexOf(".");

var fileValueSuffix = fileValue.substring(index); // 获取文件后缀

if (fileValueSuffix.toLowerCase() === ".ofd") {

return "OFD"; // 文件是 OFD 类型

} else {

return "其他类型"; // 文件不是 OFD 类型

}}

// 示例用法var fileName = "example.ofd";var fileType = checkFile(fileName);

console.log("文件类型：" + fileType);

export function getFileExtendingName(filename) {

// 文件扩展名匹配正则

var reg = /\.[^\.]+$/

var matches = reg.exec(filename)

if (matches) {

return matches[0]

}

return ''

}

20241112 Vxe-table判断校验是第几行问题

<vxe-table

@valid-error="errorEvent"

方法一：

errorEvent({ row, rowIndex }) {

this.cellClickVxe({ row })

方法二：

errMap[Object.keys(errMap)[0]][0].row

一键更新dblink

Portainer重启 xlykcb_global

如果启不来可能是.dmp比较旧

把最新打包的/xlykpub/发版记录/资金支出管控系统/V11.9.9.20250110/ce/空账套下载XLYKCE.dmp

放到ftp 115里

/hrp/dbmanage/dbfiles里

.dmp要换成新的

<span>{{ node.label }}</span>

</el-tooltip>

20240814formula计算

我把表头和标题的数字类型合并成一个json variables 然后把公式转成${variables.p212}*10 然后用eval(eval('`' + str + '`')) 计算

20241013replaceAll

if (column.property === 'strmainno') {

return value.replaceAll(',', '\n')

// return value.split(',').join('\n')

}

let str = "我是一段文本aaa";

let newStr = str.replace(/aaa/gm,"bbb")

//let newStr = str.replace(new RegExp("aaa","gm"),"bbb")

console.log(newStr) //我是一段文本bbb

if(!String.prototype.replaceAll){

String.prototype.replaceAll = function(str1,str2){

return this.replace(new RegExp(str1,"gm"),str2);

}

//用法:

let str = "我是一段文本aaa";

let newStr = str.replaceAll('aaa','bbb')

console.log(newStr) //我是一段文本bbb

20240308可用额计算

出差申请单/专项四个单子

第二行可用额=上一行可用额-申请金额

删除第一行，第一行可用额为最大可用额，所有额度重新计算

差旅报销单

第二行可用额=上一行可用额-报销金额

删除第一行，第一行可用额为最大可用额，所有额度重新计算

删除其他行，所有额度重新计算

如果是删除,并有申请金额

每组的第一条改变资金来源后,第二条要是预算额的最大值

最大可用额=最大可用额-申请金额

如果有原始申请额度,并且改变的报销金额比原始申请额度小，减原始申请额度,否则减当前额度

支出申请单

第二行可用额=上一行可用额-申请金额

删除第一行，第一行可用额为最大可用额，所有额度重新计算

每组的第一条改变资金来源后,第二条要是预算额的最大值
