共享一個簡單的 Javacript Helper library，以后會更新！

// JavaScript Document // js配置 | url | 封裝方法等等 // 需要 jQuery 庫 // // // var cookie_prefix = 'cnblogs2012_'; var helperConfig= {DOMAIN: '.tom.com',setCookie: function(name ,val ,extime , domain){var exdate = new Date();var extime = extime ? extime : 12 * 30 * 24 * 60 * 60 * 1000;exdate.setTime(exdate.getTime() + extime);name = cookie_prefix + name;var domain = domain ? domain : this.DOMAIN;document.cookie = name + "=" + val + ";expires=" + exdate.toGMTString()+";domain="+domain+";path=/";},getCookieVal: function(offset){var endstr = document.cookie.indexOf (";", offset);if (endstr == -1)endstr = document.cookie.length;return unescape(document.cookie.substring(offset, endstr));},getCookie: function(name){var arg = cookie_prefix + name + "=";var alen = arg.length;var clen = document.cookie.length;var i = 0;while (i < clen){var j = i + alen;if (document.cookie.substring(i, j) == arg)return this.getCookieVal (j);i = document.cookie.indexOf(" ", i) + 1;if (i == 0) break;}return null;},delCookie: function(name,domain){var domain = domain ? domain : this.DOMAIN;this.setCookie(name ,'' ,-1 , domain); // var exdate = new Date(); // exdate.setTime (exdate.getTime() - 10000); // alert(name + "=''; expires="+ exdate.toGMTString()+";domain="+domain+";path=/"); // document.cookie = name + "=''; expires="+ exdate.toGMTString()+";path=/"; },htmldecode:function(input){var converter = document.createElement("DIV");converter.innerHTML = input;var output = converter.innerHTML;converter = null;return output.toString();},//獲得瀏覽器類型getBrower:function(){if(navigator.userAgent.indexOf("MSIE")>0){return"MSIE"}if(navigator.userAgent.indexOf("Firefox")>0){return"Firefox"}if(navigator.userAgent.indexOf("Safari")>0){return"Safari"}if(navigator.userAgent.indexOf("Camino")>0){return"Camino"}if(navigator.userAgent.indexOf("Gecko/")>0){return"Gecko"}} }

另一個：

var helper2 = {htmlEncode: function(j) {if (!j) return '';j = typeof j != 'string' ? j.toString() : j;j = j.replace(/&/g, '&amp;');j = j.replace(/</g, '&lt;');j = j.replace(/>/g, '&gt;');return j;},setCookie: function(j, k, l) {document.cookie = j + '=' + k + (!l ? '; expires=Thu, 6 Oct 2016 01:00:00 UTC; path=/' : '');},getCookie: function(j) {var k = document.cookie.match(new RegExp('(^|\\s|;)' + j + '=([^;]*)'));return k && k.length > 0 ? k[2] : '';},htmlEncode: function(j) {var k = function(o) {var p = new h.element('span');p.setText(o);return p.getHtml();},l = k('\n').toLowerCase() == '<br>' ?function(o) {return k(o).replace(/<br>/gi, '\n');} : k, m = k('>') == '>' ?function(o) {return l(o).replace(/>/g, '&gt;');} : l, n = k(' ') == '&nbsp; ' ?function(o) {return m(o).replace(/&nbsp;/g, ' ');} : m;this.htmlEncode = n;return this.htmlEncode(j);}};
