1. 為元素添加 on 方法

Element.prototype.on = Element.prototype.addEventListener;NodeList.prototype.on = function (event, fn) {、[]['forEach'].call(this, function (el) {el.on(event, fn);});return this; };

2. 為元素添加trigger方法

Element.prototype.trigger = function(type, data) {var event = document.createEvent("HTMLEvents");event.initEvent(type, true, true);event.data = data || {};event.eventName = type;event.target = this;this.dispatchEvent(event);return this; };NodeList.prototype.trigger = function(event) {[]["forEach"].call(this, function(el) {el["trigger"](event);});return this; };

3. 轉義 HTML 標簽

function HtmlEncode(text) {return text.replace(/&/g, "&").replace(/\"/g, '"').replace(/</g, "<").replace(/>/g, ">"); }

4. HTML 標簽轉義

// HTML 標簽轉義 // @param {Array.<DOMString>} templateData 字符串類型的tokens // @param {...} ..vals 表達式占位符的運算結果tokens // function SaferHTML(templateData) {var s = templateData[0];for (var i = 1; i < arguments.length; i++) {var arg = String(arguments[i]);// Escape special characters in the substitution.s += arg.replace(/&/g, "&amp;").replace(/</g, "&lt;").replace(/>/g, "&gt;");// Don't escape special characters in the template.s += templateData[i];}return s; } // 調用 var html = SaferHTML`<p>這是關于字符串模板的介紹</p>`;

5. 跨瀏覽器綁定事件

function addEventSamp(obj, evt, fn) {if (!oTarget) {return;}if (obj.addEventListener) {obj.addEventListener(evt, fn, false);} else if (obj.attachEvent) {obj.attachEvent("on" + evt, fn);} else {oTarget["on" + sEvtType] = fn;} }

(function() {var fn = function() {var w = document.documentElement? document.documentElement.clientWidth: document.body.clientWidth,r = 1255,b = Element.extend(document.body),classname = b.className;if (w < r) {//當窗體的寬度小于1255的時候執行相應的操作} else {//當窗體的寬度大于1255的時候執行相應的操作}};if (window.addEventListener) {window.addEventListener("resize", function() {fn();});} else if (window.attachEvent) {window.attachEvent("onresize", function() {fn();});}fn(); })();

56. 滾動到頂部

// 使用document.documentElement.scrollTop 或 document.body.scrollTop 獲取到頂部的距離，從頂部 // 滾動一小部分距離。使用window.requestAnimationFrame()來滾動。 // @example // scrollToTop(); function scrollToTop() {var c = document.documentElement.scrollTop || document.body.scrollTop;if (c > 0) {window.requestAnimationFrame(scrollToTop);window.scrollTo(0, c - c / 8);} }

57. 設置Cookie值

function setCookie(name, value, Hours) {var d = new Date();var offset = 8;var utc = d.getTime() + d.getTimezoneOffset() * 60000;var nd = utc + 3600000 * offset;var exp = new Date(nd);exp.setTime(exp.getTime() + Hours * 60 * 60 * 1000);document.cookie =name +"=" +escape(value) +";path=/;expires=" +exp.toGMTString() +";domain=360doc.com;"; }

58. 設為首頁

function setHomepage() {if (document.all) {document.body.style.behavior = "url(#default#homepage)";document.body.setHomePage("http://w3cboy.com");} else if (window.sidebar) {if (window.netscape) {try {netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");} catch (e) {alert("該操作被瀏覽器拒絕，如果想啟用該功能，請在地址欄內輸入 about:config,然后將項 signed.applets.codebase_principal_support 值該為true");}}var prefs = Components.classes["@mozilla.org/preferences-service;1"].getService(Components.interfaces.nsIPrefBranch);prefs.setCharPref("browser.startup.homepage", "http://w3cboy.com");} }

59. 按字母排序，對每行進行數組排序

function setSort() {var text = K1.value.split(/[\r\n]/).sort().join("\r\n"); //順序var test = K1.value.split(/[\r\n]/).sort().reverse().join("\r\n"); //反序K1.value = K1.value != text ? text : test; }

60. 延時執行

// 比如 sleep(1000) 意味著等待1000毫秒，還可從 Promise、Generator、Async/Await 等角度實現。 // Promise const sleep = time => {return new Promise(resolve => setTimeout(resolve, time)); };sleep(1000).then(() => {console.log(1); });// Generator function* sleepGenerator(time) {yield new Promise(function(resolve, reject) {setTimeout(resolve, time);}); }sleepGenerator(1000).next().value.then(() => {console.log(1);});//async function sleep(time) {return new Promise(resolve => setTimeout(resolve, time)); }async function output() {let out = await sleep(1000);console.log(1);return out; }output();function sleep(callback, time) {if (typeof callback === "function") {setTimeout(callback, time);} }function output() {console.log(1); }sleep(output, 1000);

61. 判斷是否以某個字符串開頭

String.prototype.startWith = function(s) {return this.indexOf(s) == 0; };

62. 清除腳本內容

function stripscript(s) {return s.replace(/<script.*?>.*?<\/script>/gi, ""); }

63. 時間個性化輸出功能

/* 1、< 60s, 顯示為“剛剛” 2、>= 1min && < 60 min, 顯示與當前時間差“XX分鐘前” 3、>= 60min && < 1day, 顯示與當前時間差“今天 XX:XX” 4、>= 1day && < 1year, 顯示日期“XX月XX日 XX:XX” 5、>= 1year, 顯示具體日期“XXXX年XX月XX日 XX:XX” */ function timeFormat(time) {var date = new Date(time),curDate = new Date(),year = date.getFullYear(),month = date.getMonth() + 10,day = date.getDate(),hour = date.getHours(),minute = date.getMinutes(),curYear = curDate.getFullYear(),curHour = curDate.getHours(),timeStr;if (year < curYear) {timeStr = year + "年" + month + "月" + day + "日 " + hour + ":" + minute;} else {var pastTime = curDate - date,pastH = pastTime / 3600000;if (pastH > curHour) {timeStr = month + "月" + day + "日 " + hour + ":" + minute;} else if (pastH >= 1) {timeStr = "今天 " + hour + ":" + minute + "分";} else {var pastM = curDate.getMinutes() - minute;if (pastM > 1) {timeStr = pastM + "分鐘前";} else {timeStr = "剛剛";}}}return timeStr; }

64. 全角轉換為半角函數

function toCDB(str) {var result = "";for (var i = 0; i < str.length; i++) {code = str.charCodeAt(i);if (code >= 65281 && code <= 65374) {result += String.fromCharCode(str.charCodeAt(i) - 65248);} else if (code == 12288) {result += String.fromCharCode(str.charCodeAt(i) - 12288 + 32);} else {result += str.charAt(i);}}return result; }

65. 半角轉換為全角

function toDBC(str) {var result = "";for (var i = 0; i < str.length; i++) {code = str.charCodeAt(i);if (code >= 33 && code <= 126) {result += String.fromCharCode(str.charCodeAt(i) + 65248);} else if (code == 32) {result += String.fromCharCode(str.charCodeAt(i) + 12288 - 32);} else {result += str.charAt(i);}}return result; }

66. 金額大寫轉換函數

function transform(tranvalue) {try {var i = 1;var dw2 = new Array("", "萬", "億"); //大單位var dw1 = new Array("拾", "佰", "仟"); //小單位var dw = new Array("零","壹","貳","叁","肆","伍","陸","柒","捌","玖"); //整數部分用//以下是小寫轉換成大寫顯示在合計大寫的文本框中//分離整數與小數var source = splits(tranvalue);var num = source[0];var dig = source[1];//轉換整數部分var k1 = 0; //計小單位var k2 = 0; //計大單位var sum = 0;var str = "";var len = source[0].length; //整數的長度for (i = 1; i <= len; i++) {var n = source[0].charAt(len - i); //取得某個位數上的數字var bn = 0;if (len - i - 1 >= 0) {bn = source[0].charAt(len - i - 1); //取得某個位數前一位上的數字}sum = sum + Number(n);if (sum != 0) {str = dw[Number(n)].concat(str); //取得該數字對應的大寫數字，并插入到str字符串的前面if (n == "0") sum = 0;}if (len - i - 1 >= 0) {//在數字范圍內if (k1 != 3) {//加小單位if (bn != 0) {str = dw1[k1].concat(str);}k1++;} else {//不加小單位，加大單位k1 = 0;var temp = str.charAt(0);if (temp == "萬" || temp == "億")//若大單位前沒有數字則舍去大單位str = str.substr(1, str.length - 1);str = dw2[k2].concat(str);sum = 0;}}if (k1 == 3) {//小單位到千則大單位進一k2++;}}//轉換小數部分var strdig = "";if (dig != "") {var n = dig.charAt(0);if (n != 0) {strdig += dw[Number(n)] + "角"; //加數字}var n = dig.charAt(1);if (n != 0) {strdig += dw[Number(n)] + "分"; //加數字}}str += "元" + strdig;} catch (e) {return "0元";}return str; } //拆分整數與小數 function splits(tranvalue) {var value = new Array("", "");temp = tranvalue.split(".");for (var i = 0; i < temp.length; i++) {value = temp;}return value; }

67. 清除空格

String.prototype.trim = function() {var reExtraSpace = /^\s*(.*?)\s+$/;return this.replace(reExtraSpace, "$1"); };// 清除左空格 function ltrim(s) {return s.replace(/^(\s*|　*)/, ""); }// 清除右空格 function rtrim(s) {return s.replace(/(\s*|　*)$/, ""); }

68. 隨機數時間戳

function uniqueId() {var a = Math.random,b = parseInt;return (Number(new Date()).toString() + b(10 * a()) + b(10 * a()) + b(10 * a())); }

69. 實現utf8解碼

function utf8_decode(str_data) {var tmp_arr = [],i = 0,ac = 0,c1 = 0,c2 = 0,c3 = 0;str_data += "";while (i < str_data.length) {c1 = str_data.charCodeAt(i);if (c1 < 128) {tmp_arr[ac++] = String.fromCharCode(c1);i++;} else if (c1 > 191 && c1 < 224) {c2 = str_data.charCodeAt(i + 1);tmp_arr[ac++] = String.fromCharCode(((c1 & 31) << 6) | (c2 & 63));i += 2;} else {c2 = str_data.charCodeAt(i + 1);c3 = str_data.charCodeAt(i + 2);tmp_arr[ac++] = String.fromCharCode(((c1 & 15) << 12) | ((c2 & 63) << 6) | (c3 & 63));i += 3;}}return tmp_arr.join(""); }
