Vue3 工具

使用

import { isUndefined } from 'm-vue-util';

console.log(isUndefined('test'));

方法

isUndefined(obj: any) //校验变量是否存在
isNull(obj: any) //校验变量是否是NULL
isString(obj: any) //校验变量是否是字符串
isNumber(obj: any) //校验变量是否是数字
isArray(obj: any) //校验变量是否是数组
isDate(obj: any) //校验变量是否是时间
isFunction(obj: any) //校验变量是否是方法
isObject(obj: any) //校验变量是否是对象
isBoolean(obj: any) //校验变量是否是布尔值
isSymbol(obj: any) //校验变量是否是Symbol
isRegExp(obj: any) //校验变量是否是正则
isError(obj: any) //校验变量是否是Error
isHTMLDocument(obj: any) //校验变量是否是HTMLDocument
isEmpty(obj: any) //校验变量是否是空（undefined、null、空字符串、NaN、空数组、空对象）
trim(obj: string, position = 'both') //去除字符串空格（position[both：前后空格，left：前空格，right：后空格，all：所有空格]）
clone(obj: any) //深度克隆对象
mergeObject(target: { [key: string]: any }, ...sources: Array<{ [key: string]: any }>) //深度合并对象
getObject(obj: { [key: string]: any }, key: string | Array<string>, defaultValue?: any) //获取多级对象值
firstCase(str: string) //首字母大写
guid(rod = true) //生成UUID
debounce(fn: () => void, delay = 500, immdiate = false, name?: string, callBack: (value: any) => void) //防抖函数（delay时间间隔毫秒，immdiate是否立即执行，name唯一标识名称）
throttle(fn: () => void, delay = 500, immdiate = true, name?: string, callBack: (value: any) => void) //节流函数（delay时间间隔毫秒，immdiate是否立即执行，name唯一标识名称）
getUnit(value: string | number) //动态尺寸后缀
isUrl(str: string) //判断字符串是否是URL
download(content: string, name?: string) //浏览器下载（content下载地址或者bse64内容）
readFileText(file: File, callBack: (content: string) => void) //读取文件内容
readFileDataURL(file: File, callBack: (result: string) => void) //读取文件地址
toStr(obj: any) //数据转字符串（undefined、null、字符串、数字、数组、对象、方法）
strEval(str: string) //字符串转可执行方法
objToUrl(obj: { [key: string]: any }) //对象转URL地址
ajax(url: string, options?: { [key: string]: any }, success?: (value: any) => void, error?: (status: number, e: any) => void) //远程请求（options = { type: '', params:{}, headers: {}, mimeType: '', timeout: 500 }）
loadJS(url: string) //加载JS文件，返回Promise加载完成执行then
listToTree(list: Array<{ [key: string]: any }>, idName = 'id', childrenName = 'children') //列表转树形
treeToList(tree: Array<{ [key: string]: any }>, childrenName = 'children') //树形转列表
filterTree(tree: Array<{ [key: string]: any }>, fields: Array<string>, value: string, childrenName = 'children') //树形过滤
findTree(tree: Array<{ [key: string]: any }>, where: (value: { [key: string]: any }) => {}, childrenName = 'children') //通过自定义条件查询树形节点
findTreeById(tree: Array<{ [key: string]: any }>, id: number | string, idName = 'id', childrenName = 'children') //通过唯一标识查询树形节点
eachTree(tree: Array<{ [key: string]: any }>, where: (value: { [key: string]: any }) => void, childrenName = 'children') //循环遍历树形
loadImage(url: string, callBack: (img: any) => void) //加载图片
local(key: string, value?: any) //长期缓存
session(key: string, value?: any) //临时缓存
removeLocal(key: string) //移除长期缓存
removeSession(key: string) //移除临时缓存
