8、Storage 储存操作
class StorageFn {constructor () {this.ls = window.localStorage;this.ss = window.sessionStorage;}/*-----------------cookie---------------------*//*设置cookie*/setCookie (name, value, day) {var setting = arguments[0];if (Object.prototype.toString.call(setting).slice(8, -1) === 'Object'){for (var i in setting) {var oDate = new Date();oDate.setDate(oDate.getDate() + day);document.cookie = i + '=' + setting[i] + ';expires=' + oDate;}}else{var oDate = new Date();oDate.setDate(oDate.getDate() + day);document.cookie = name + '=' + value + ';expires=' + oDate;}}/*获取cookie*/getCookie (name) {var arr = document.cookie.split('; ');for (var i = 0; i < arr.length; i++) {var arr2 = arr[i].split('=');if (arr2[0] == name) {return arr2[1];}}return '';}/*删除cookie*/removeCookie (name) {this.setCookie(name, 1, -1);}/*-----------------localStorage---------------------*//*设置localStorage*/setLocal(key, val) {var setting = arguments[0];if (Object.prototype.toString.call(setting).slice(8, -1) === 'Object'){for(var i in setting){this.ls.setItem(i, JSON.stringify(setting[i]))}}else{this.ls.setItem(key, JSON.stringify(val))}}/*获取localStorage*/getLocal(key) {if (key) return JSON.parse(this.ls.getItem(key))return null;}/*移除localStorage*/removeLocal(key) {this.ls.removeItem(key)}/*移除所有localStorage*/clearLocal() {this.ls.clear()}/*-----------------sessionStorage---------------------*//*设置sessionStorage*/setSession(key, val) {var setting = arguments[0];if (Object.prototype.toString.call(setting).slice(8, -1) === 'Object'){for(var i in setting){this.ss.setItem(i, JSON.stringify(setting[i]))}}else{this.ss.setItem(key, JSON.stringify(val))}}/*获取sessionStorage*/getSession(key) {if (key) return JSON.parse(this.ss.getItem(key))return null;}/*移除sessionStorage*/removeSession(key) {this.ss.removeItem(key)}/*移除所有sessionStorage*/clearSession() {this.ss.clear()}}
9、 Other 其它操作
/*获取网址参数*/getURL(name){var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");var r = window.location.search.substr(1).match(reg);if(r!=null) return r[2]; return null;}/*获取全部url参数,并转换成json对象*/getUrlAllParams (url) {var url = url ? url : window.location.href;var _pa = url.substring(url.indexOf('?') + 1),_arrS = _pa.split('&'),_rs = {};for (var i = 0, _len = _arrS.length; i < _len; i++) {var pos = _arrS[i].indexOf('=');if (pos == -1) {continue;}var name = _arrS[i].substring(0, pos),value = window.decodeURIComponent(_arrS[i].substring(pos + 1));_rs[name] = value;}return _rs;}/*删除url指定参数，返回url*/delParamsUrl(url, name){var baseUrl = url.split('?')[0] + '?';var query = url.split('?')[1];if (query.indexOf(name)>-1) {var obj = {}var arr = query.split("&");for (var i = 0; i < arr.length; i++) {arr[i] = arr[i].split("=");obj[arr[i][0]] = arr[i][1];};delete obj[name];var url = baseUrl + JSON.stringify(obj).replace(/[\"\{\}]/g,"").replace(/\:/g,"=").replace(/\,/g,"&");return url}else{return url;}}/*获取十六进制随机颜色*/getRandomColor () {return '#' + (function(h) {return new Array(7 - h.length).join("0") + h;})((Math.random() * 0x1000000 << 0).toString(16));}/*图片加载*/imgLoadAll(arr,callback){var arrImg = [];for (var i = 0; i < arr.length; i++) {var img = new Image();img.src = arr[i];img.onload = function(){arrImg.push(this);if (arrImg.length == arr.length) {callback && callback();}}}}/*音频加载*/loadAudio(src, callback) {var audio = new Audio(src);audio.onloadedmetadata = callback;audio.src = src;}/*DOM转字符串*/domToStirng(htmlDOM){var div= document.createElement("div");div.appendChild(htmlDOM);return div.innerHTML}/*字符串转DOM*/stringToDom(htmlString){var div= document.createElement("div");div.innerHTML=htmlString;return div.children[0];}/*** 光标所在位置插入字符，并设置光标位置** @param {dom} 输入框* @param {val} 插入的值* @param {posLen} 光标位置处在 插入的值的哪个位置*/setCursorPosition (dom,val,posLen) {var cursorPosition = 0;if(dom.selectionStart){cursorPosition = dom.selectionStart;}this.insertAtCursor(dom,val);dom.focus();console.log(posLen)dom.setSelectionRange(dom.value.length,cursorPosition + (posLen || val.length));}/*光标所在位置插入字符*/insertAtCursor(dom, val) {if (document.selection){dom.focus();sel = document.selection.createRange();sel.text = val;sel.select();}else if (dom.selectionStart || dom.selectionStart == '0'){let startPos = dom.selectionStart;let endPos = dom.selectionEnd;let restoreTop = dom.scrollTop;dom.value = dom.value.substring(0, startPos) + val + dom.value.substring(endPos, dom.value.length);if (restoreTop > 0){dom.scrollTop = restoreTop;}dom.focus();dom.selectionStart = startPos + val.length;dom.selectionEnd = startPos + val.length;} else {dom.value += val;dom.focus();}}
