摘要:最新使用的組織機構代碼在年頒布實施,由位數字或大寫拉丁字母本體代碼和位數字或大寫拉丁字母校驗碼組成。本體代碼采用系列即分區段順序編碼方法。
1.截取指定字節數的字符串
/** * 截取指定字節的字符串 * @param str 要截取的字符穿 * @param len 要截取的長度,根據字節計算 * @param suffix 截取前len個后,其余的字符的替換字符,一般用“…” * @returns {*} */ function cutString(str, len, suffix) { if (!str) return ""; if (len <= 0) return ""; if (!suffix) suffix = ""; var templen = 0; for (var i = 0; i < str.length; i++) { if (str.charCodeAt(i) > 255) { templen += 2; } else { templen++ } if (templen == len) { return str.substring(0, i + 1) + suffix; } else if (templen > len) { return str.substring(0, i) + suffix; } } return str; }2.判斷是否微信
/** * 判斷微信瀏覽器 * @returns {Boolean} */ function isWeiXin() { var ua = window.navigator.userAgent.toLowerCase(); if (ua.match(/MicroMessenger/i) == "micromessenger") { return true; } else { return false; } }3.獲取時間格式的幾個舉例
function getTimeFormat(time) { var date = new Date(parseInt(time) * 1000); var month, day, hour, min; parseInt(date.getMonth()) + 1 < 10 ? month = "0" + (parseInt(date.getMonth()) + 1) : month = parseInt(date.getMonth()) + 1; date.getDate() < 10 ? day = "0" + date.getDate() : day = date.getDate(); date.getHours() < 10 ? hour = "0" + date.getHours() : hour = date.getHours(); date.getMinutes() < 10 ? min = "0" + date.getMinutes() : min = date.getMinutes(); return [month, day].join("-") + " " + hour + ":" + min } function getTimeFormatYMD(time) { var date = new Date(parseInt(time) * 1000); var year, month, day; year = date.getFullYear(); parseInt(date.getMonth()) + 1 < 10 ? month = "0" + (parseInt(date.getMonth()) + 1) : month = parseInt(date.getMonth()) + 1; date.getDate() < 10 ? day = "0" + date.getDate() : day = date.getDate(); return [year, month, day].join("-") } function getTimeFormatAll(time) { var date = new Date(parseInt(time) * 1000); var year, month, day, hour, min, second; year = date.getFullYear(); parseInt(date.getMonth()) + 1 < 10 ? month = "0" + (parseInt(date.getMonth()) + 1) : month = parseInt(date.getMonth()) + 1; date.getDate() < 10 ? day = "0" + date.getDate() : day = date.getDate(); date.getHours() < 10 ? hour = "0" + date.getHours() : hour = date.getHours(); date.getMinutes() < 10 ? min = "0" + date.getMinutes() : min = date.getMinutes(); date.getSeconds() < 10 ? second = "0" + date.getSeconds() : second = date.getSeconds(); return [year, month, day].join("-") + " " + hour + ":" + min + ":" + second }4.獲取字符串字節長度
/** * 獲取字符串字節長度 * @param {String} * @returns {Boolean} */ function checkLength(v) { var realLength = 0; var len = v.length; for (var i = 0; i < len; i++) { var charCode = v.charCodeAt(i); if (charCode >= 0 && charCode <= 128) realLength += 1; else realLength += 2; } return realLength; }5.對象克隆、深拷貝
/** * 對象克隆&深拷貝 * @param obj * @returns {{}} */ function cloneObj(obj) { var newO = {}; if (obj instanceof Array) { newO = []; } for (var key in obj) { var val = obj[key]; newO[key] = typeof val === "object" ? arguments.callee(val) : val; } return newO; };
克隆拷貝增強版
/** * 對象克隆&深拷貝 * @param obj * @returns {{}} */ function clone(obj) { // Handle the 3 simple types, and null or undefined if (null == obj || "object" != typeof obj) return obj; // Handle Date if (obj instanceof Date) { var copy = new Date(); copy.setTime(obj.getTime()); return copy; } // Handle Array if (obj instanceof Array) { var copy = []; for (var i = 0, len = obj.length; i < len; ++i) { copy[i] = clone(obj[i]); } return copy; } // Handle Object if (obj instanceof Object) { var copy = {}; for (attr in obj) { if (obj.hasOwnProperty(attr)) copy[attr] = clone(obj[attr]); } return copy; } throw new Error("Unable to copy obj! Its type isn"t supported."); }
測試用例:
var origin = { a: "text", b: null, c: undefined, e: { f: [1, 2] } }6.組織結構代碼證驗證
驗證規則:
組織機構代碼是每一個機關、社會團體、企事業單位在全國范圍內唯一的、始終不變的法定代碼標識。最新使用的組織機構代碼在1997年頒布實施,由8位數字(或大寫拉丁字母)本體代碼和1位數字(或大寫拉丁字母)校驗碼組成。本體代碼采用系列(即分區段)順序編碼方法。校驗碼按下列公式計算:8 C9 = 11 - MOD(∑Ci * Wi,11)… (2) i = 1其中:MOD——表示求余函數;i——表示代碼字符從左到右位置序號;Ci——表示第i位置上的代碼字符的值,采用附錄A“代碼字符集”所列字符;C9——表示校驗碼;Wi——表示第i位置上的加權因子,其數值如下表:i 1 2 3 4 5 6 7 8 Wi 3 7 9 10 5 8 4 2當MOD函數值為1(即C9 = 10)時,校驗碼用字母X表示。
驗證方法:
checkOrgCodeValid: function(el) { var txtval = el.value; var values = txtval.split("-"); var ws = [3, 7, 9, 10, 5, 8, 4, 2]; var str = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"; var reg = /^([0-9A-Z]){8}$/; if (!reg.test(values[0])) { return false } var sum = 0; for (var i = 0; i < 8; i++) { sum += str.indexOf(values[0].charAt(i)) * ws[i]; } var C9 = 11 - (sum % 11); var YC9 = values[1] + ""; if (C9 == 11) { C9 = "0"; } else if (C9 == 10) { C9 = "X"; } else { C9 = C9 + ""; } return YC9 == C9; }7.身份證號驗證
/** * 驗證身份證號 * @param el 號碼輸入input * @returns {boolean} */ function checkCardNo(el) { var txtval = el.value; var reg = /(^d{15}$)|(^d{18}$)|(^d{17}(d|X|x)$)/; return reg.test(txtval) }8.js正則為url添加http標識
9.URL有效性校驗方法
/** * URL有效性校驗 * @param str_url * @returns {boolean} */ function isURL(str_url) { // 驗證url var strRegex = "^((https|http|ftp|rtsp|mms)?://)" + "?(([0-9a-z_!~*"().&=+$%-]+: )?[0-9a-z_!~*"().&=+$%-]+@)?" // ftp的user@ + "(([0-9]{1,3}.){3}[0-9]{1,3}" // IP形式的URL- 199.194.52.184 + "|" // 允許IP和DOMAIN(域名) + "([0-9a-z_!~*"()-]+.)*" // 域名- www. + "([0-9a-z][0-9a-z-]{0,61})?[0-9a-z]." // 二級域名 + "[a-z]{2,6})" // first level domain- .com or .museum + "(:[0-9]{1,4})?" // 端口- :80 + "((/?)|" // a slash isn"t required if there is no file name + "(/[0-9a-z_!~*"().;?:@&=+$,%#-]+)+/?)$"; var re = new RegExp(strRegex); return re.test(str_url); } // 建議的正則 functionisURL(str) { return !! str.match(/(((^https?:(?://)?)(?:[-;:&=+$,w]+@)?[A-Za-z0-9.-]+|(?:www.|[-;:&=+$,w]+@)[A-Za-z0-9.-]+)((?:/[+~%/.w-_]*)???(?:[-+=&;%@.w_]*)#?(?:[w]*))?)$/g); }10.自定義jsonp方法
/** * 自定義封裝jsonp方法 * @param options */ jsonp = function(options) { options = options || {}; if (!options.url || !options.callback) { throw new Error("參數不合法"); } //創建 script 標簽并加入到頁面中 var callbackName = ("jsonp_" + Math.random()).replace(".", ""); var oHead = document.getElementsByTagName("head")[0]; options.data[options.callback] = callbackName; var params = formatParams(options.data); var oS = document.createElement("script"); oHead.appendChild(oS); //創建jsonp回調函數 window[callbackName] = function(json) { oHead.removeChild(oS); clearTimeout(oS.timer); window[callbackName] = null; options.success && options.success(json); }; //發送請求 oS.src = options.url + "?" + params; //超時處理 if (options.time) { oS.timer = setTimeout(function() { window[callbackName] = null; oHead.removeChild(oS); options.fail && options.fail({ message: "超時" }); }, time); } }; /** * 格式化參數 * @param data * @returns {string} */ formatParams = function(data) { var arr = []; for (var name in data) { arr.push(encodeURIComponent(name) + "=" + encodeURIComponent(data[name])); } return arr.join("&"); }11.cookie操作
//寫cookies setCookie = function(name, value, time) { var strsec = getsec(time); var exp = new Date(); exp.setTime(exp.getTime() + strsec * 1); document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString(); } //cookie操作輔助函數 getsec = function(str) { var str1 = str.substring(1, str.length) * 1; var str2 = str.substring(0, 1); if (str2 == "s") { return str1 * 1000; } else if (str2 == "h") { return str1 * 60 * 60 * 1000; } else if (str2 == "d") { return str1 * 24 * 60 * 60 * 1000; } } //讀取cookies getCookie = function(name) { var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)"); if (arr = document.cookie.match(reg)) return (arr[2]); else return null; } //刪除cookies delCookie = function(name) { var exp = new Date(); exp.setTime(exp.getTime() - 1); var cval = getCookie(name); if (cval != null) document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString(); }12.生成隨機字符串 (可指定長度)
/** * 生成隨機字符串(可指定長度) * @param len * @returns {string} */ randomString = function(len) { len = len || 8; var $chars = "ABCDEFGHJKMNPQRSTWXYZabcdefhijkmnprstwxyz2345678"; /****默認去掉了容易混淆的字符oOLl,9gq,Vv,Uu,I1****/ var maxPos = $chars.length; var pwd = ""; for (var i = 0; i < len; i++) { pwd += $chars.charAt(Math.floor(Math.random() * maxPos)); } return pwd; }13.瀏覽器判斷
function parseUA() { var u = navigator.userAgent; var u2 = navigator.userAgent.toLowerCase(); return { //移動終端瀏覽器版本信息 trident: u.indexOf("Trident") > -1, //IE內核 presto: u.indexOf("Presto") > -1, //opera內核 webKit: u.indexOf("AppleWebKit") > -1, //蘋果、谷歌內核 gecko: u.indexOf("Gecko") > -1 && u.indexOf("KHTML") == -1, //火狐內核 mobile: !!u.match(/AppleWebKit.*Mobile.*/), //是否為移動終端 ios: !!u.match(/(i[^;]+;( U;)? CPU.+Mac OS X/), //ios終端 android: u.indexOf("Android") > -1 || u.indexOf("Linux") > -1, //android終端或uc瀏覽器 iPhone: u.indexOf("iPhone") > -1, //是否為iPhone或者QQHD瀏覽器 iPad: u.indexOf("iPad") > -1, //是否iPad webApp: u.indexOf("Safari") == -1, //是否web應該程序,沒有頭部與底部 iosv: u.substr(u.indexOf("iPhone OS") + 9, 3), weixin: u2.match(/MicroMessenger/i) == "micromessenger", ali: u.indexOf("AliApp") > -1, }; } var ua = parseUA(); if (!ua.mobile) { location.href = "./pc.html"; }14.Rem移動端適配
var rem = { baseRem: 40, // 基準字號,按照iphone6應該為20,此處擴大2倍,便于計算 baseWidth: 750, // 基準尺寸寬,此處是按照ihpone6的尺寸 rootEle: document.getElementsByTagName("html")[0], initHandle: function() { this.setRemHandle(); this.resizeHandle(); }, setRemHandle: function() { var clientWidth = document.documentElement.clientWidth || document.body.clientWidth; this.rootEle.style.fontSize = clientWidth * this.baseRem / this.baseWidth + "px"; }, resizeHandle: function() { var that = this; window.addEventListener("resize", function() { setTimeout(function() { that.setRemHandle(); }, 300); }); } }; rem.initHandle();15.獲取url后參數
function GetRequest() { var url = location.search; //獲取url中"?"符后的字串 var theRequest = new Object(); if (url.indexOf("?") != -1) { var str = url.substr(1); strs = str.split("&"); for (var i = 0; i < strs.length; i++) { theRequest[strs[i].split("=")[0]] = (strs[i].split("=")[1]); } } return theRequest; }16.動態加載JS
function loadScript(url, callback) { var script = document.createElement("script"); script.type = "text/"; if (typeof(callback) != "undefined") { if (script.readyState) { script.onreadystatechange = function() { if (script.readyState == "loaded" || script.readyState == "complete") { script.onreadystatechange = null; callback(); } }; } else { script.onload = function() { callback(); }; } } script.src = url; document.body.appendChild(script); }17.生成隨機顏色值
function getRandomColor () { const rgb = [] for (let i = 0 ; i < 3; ++i){ let color = Math.floor(Math.random() * 256).toString(16) color = color.length == 1 ? "0" + color : color rgb.push(color) } return "#" + rgb.join("") }18.事件綁定與解綁
ElementClass.prototype.on = function (name, callback) { this.callbacks[name] = this.callbacks[name] || [] this.callbacks[name].push(callback) } ElementClass.prototype.off = function (name, callback) { var callbacks = this.callbacks[name] if (callbacks && callbacks instanceof Array) { var index = callbacks.indexOf(callback) if (index !== -1) callbacks.splice(index, 1) } } ElementClass.prototype.trigger = function (name, params) { var callbacks = this.callbacks[name] if (callbacks && callbacks instanceof Array) { callbacks.forEach((cb) => { cb(params) }) } }19.移動端音頻播放
/** * 移動端H5播放音樂處理,兼容微信端 * @param el 音樂Audio元素 */ function playMusic(el) { var b = document.getElementById(el); var c = function c() { b.play(); document.removeEventListener("touchstart", c, true); }; b.play(); document.addEventListener("WeixinJSBridgeReady", function () { c(); }, false); document.addEventListener("YixinJSBridgeReady", function () { c(); }, false); document.addEventListener("touchstart", c, true); }20.移動端視頻適配
