- function cutstr(str, len) {
- var temp;
- var icount = 0;
- var patrn = /[^\x00-\xff]/;
- var strre = "";
- for (var i = 0; i < str.length; i++) {
- if (icount < len - 1) {
- temp = str.substr(i, 1);
- if (patrn.exec(temp) == null) {
- icount = icount + 1
- } else {
- icount = icount + 2
- }
- strre += temp
- } else {
- break
- }
- }
- return strre + "..."
- }
2、原生JavaScript获取域名主机
- function getHost(url) {
- var host = "null";
- if(typeof url == "undefined"|| null == url) {
- url = window.location.href;
- }
- var regex = /^\w+\:\/\/([^\/]*).*/;
- var match = url.match(regex);
- if(typeof match != "undefined" && null != match) {
- host = match[1];
- }
- return host;
- }
3、原生JavaScript清除空格
- String.prototype.trim = function() {
- var reExtraSpace = /^\s*(.*?)\s+$/;
- return this.replace(reExtraSpace, "$1")
- }
4、原生JavaScript替换全部
- String.prototype.replaceAll = function(s1, s2) {
- return this.replace(new RegExp(s1, "gm"), s2)
- }
5、原生JavaScript转义html标签
- function HtmlEncode(text) {
- return text.replace(/&/g, '&').replace(/\"/g, '"').replace(//g, '>')
- }
7、原生JavaScript时间日期格式转换
- Date.prototype.Format = function(formatStr) {
- var str = formatStr;
- var Week = ['日', '一', '二', '三', '四', '五', '六'];
- str = str.replace(/yyyy|YYYY/, this.getFullYear());
- str = str.replace(/yy|YY/, (this.getYear() % 100) > 9 ? (this.getYear() % 100).toString() : '0' + (this.getYear() % 100));
- str = str.replace(/MM/, (this.getMonth() + 1) > 9 ? (this.getMonth() + 1).toString() : '0' + (this.getMonth() + 1));
- str = str.replace(/M/g, (this.getMonth() + 1));
- str = str.replace(/w|W/g, Week[this.getDay()]);
- str = str.replace(/dd|DD/, this.getDate() > 9 ? this.getDate().toString() : '0' + this.getDate());
- str = str.replace(/d|D/g, this.getDate());
- str = str.replace(/hh|HH/, this.getHours() > 9 ? this.getHours().toString() : '0' + this.getHours());
- str = str.replace(/h|H/g, this.getHours());
- str = str.replace(/mm/, this.getMinutes() > 9 ? this.getMinutes().toString() : '0' + this.getMinutes());
- str = str.replace(/m/g, this.getMinutes());
- str = str.replace(/ss|SS/, this.getSeconds() > 9 ? this.getSeconds().toString() : '0' + this.getSeconds());
- str = str.replace(/s|S/g, this.getSeconds());
- return str
- }
8、原生JavaScript判断是否为数字类型
- function isDigit(value) {
- var patrn = /^[0-9]*$/;
- if (patrn.exec(value) == null || value == "") {
- return false
- } else {
- return true
- }
- }
9、原生JavaScript设置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;"
- }
10、原生JavaScript获取cookie值
- function getCookie(name) {
- var arr = document.cookie.match(new RegExp("(^| )" + name + "=([^;]*)(;|$)"));
- if (arr != null) return unescape(arr[2]);
- return null
- }
11、原生JavaScript加入收藏夹
- function AddFavorite(sURL, sTitle) {
- try {
- window.external.addFavorite(sURL, sTitle)
- } catch(e) {
- try {
- window.sidebar.addPanel(sTitle, sURL, "")
- } catch(e) {
- alert("加入收藏失败,请使用Ctrl+D进行添加")
- }
- }
- }
12、原生JavaScript设为首页
- function setHomepage() {
- if (document.all) {
- document.body.style.behavior = 'url(#default#homepage)';
- document.body.setHomePage('http://www.jq-school.com')
- } else if (window.sidebar) {
- if (window.netscape) {
- try {
- netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect")
- } catch(e) {
- alert("该操作被浏览器拒绝,如果想启用该功能,请在地址栏内输入 about:config,然后将项 signed.applets.codebase_principal_support 值该为true")
- }
- }
- var prefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components.interfaces.nsIPrefBranch);
- prefs.setCharPref('browser.startup.homepage', 'http://www.jq-school.com')
- }
- }
#p#
13、原生JavaScript判断IE6
- var ua = navigator.userAgent.toLowerCase();
- var isIE6 = ua.indexOf("msie 6") > -1;
- if (isIE6) {
- try {
- document.execCommand("BackgroundImageCache", false, true)
- } catch(e) {}
- }
14、原生JavaScript加载样式文件
- function LoadStyle(url) {
- try {
- document.createStyleSheet(url)
- } catch(e) {
- var cssLink = document.createElement('link');
- cssLink.rel = 'stylesheet';
- cssLink.type = 'text/css';
- cssLink.href = url;
- var head = document.getElementsByTagName('head')[0];
- head.appendChild(cssLink)
- }
- }
15、原生JavaScript返回脚本内容
- function evalscript(s) {
- if(s.indexOf('
