Vue中util的工具函数,下面通过实例代码给大家介绍的非常详细,具体代码如下所示:
// 防抖函数 function debounce (fn, wait) { let t return () => { let context = this let args = arguments if (t) clearTimeout(t) t = setTimeout(() => { fn.apply(context, args) }, wait) } } function flatten (arr) { // 数组扁平化 return arr.reduce((result, item) => { return result.concat(Array.isArray(item) ? flatten(item) : item) }, []) } function handleMulitePerson (sPerson) { console.log(44, sPerson.split(',')) if (typeof sPerson == 'string') { let personArr = [] sPerson.split(',').forEach(item => { let obj = { userCode: item.split('/')[0], userName: item.split('/')[1] } personArr.push(obj) }) return personArr } } function uniqueArray (array, key) { // json数组根据key去重 var result = [array[0]] for (var i = 1; i < array.length; i++) { var item = array[i] var repeat = false for (var j = 0; j < result.length; j++) { if (item[key] == result[j][key]) { repeat = true break } } if (!repeat) { result.push(item) } } return result } function setSessionStorage (key, val) { if (typeof (val) == 'object') { sessionStorage.setItem(key, JSON.stringify(val)) } else { sessionStorage.setItem(key, val) } } function getSessionStorage (key) { return sessionStorage.getItem(key) } function removeStorage (key) { sessionStorage.removeItem(key) } function urlParams () { // 获取链接参数 var str = location.search.length > 0 ? location.search.substring(1) : '' var items = str.length ? str.split('&') : [] var args = {} var item = null var name = null var value = null for (let i = 0, len = items.length; i < len; i++) { item = items[i].split('=') name = decodeURIComponent(item[0]) value = decodeURIComponent(item[1]) if (name.length) { args[name] = value } }; return args } function urlAfterParams () { var str = window.location.hash.length > 0 ? window.location.hash.substring(window.location.hash.indexOf('?') + 1) : '' var items = str.indexOf('&') > 0 ? str.split('&') : str.split('?') var args = {} var item = null var name = null var value = null for (let i = 0, len = items.length; i < len; i++) { item = items[i].split('=') name = decodeURIComponent(item[0]) value = decodeURIComponent(item[1]) if (name.length) { args[name] = value } }; return args } function parseParams (url) { url = decodeURIComponent(url) var params = {} var idx = url.indexOf('?') if (idx > 0) { var queryStr = url.substring(idx + 1) if (queryStr.length > 0) { var arr = queryStr.split('&') for (let i = 0; i < arr.length; i++) { var pair = arr[i].split('=') if (pair.length == 2 && pair[0].length > 0) { params[pair[0]] = pair[1] } } } } return params } /** 选人下拉框数据:username(userCode) */ function getSelectUserName (userName, userCode) { return userName + '(' + userCode + ')' } function getSelectLoginUser () { var userInfo = getLoginUserInfo() return getSelectUserName(userInfo.userName, userInfo.userId) } function getUserNameBySelectUserName (userName) { let i = userName.indexOf('(') return userName.substring(0, i) } /** 登录用户信息 userId userName mobileNo @returns {any} */ function getLoginUserInfo () { return JSON.parse(localStorage.getItem('userInfo')) } function getLoginUserCode () { return JSON.parse(localStorage.getItem('userInfo')).userId } export default { getNyr, getYDate, setSessionStorage, urlParams, urlAfterParams, parseParams, debounce, handleMulitePerson, uniqueArray, flatten, getSessionStorage, removeStorage, getSelectUserName, getSelectLoginUser, getLoginUserInfo, getLoginUserCode, getUserNameBySelectUserName }
