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=https://www.jb51.net/;expires=" + exp.toGMTString() + ";domain=360doc.com;"
}
10、原生JavaScript获取cookie值
复制代码 代码如下:
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
复制代码 代码如下:
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
复制代码 代码如下:
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')
}
}
13、原生JavaScript判断IE6
复制代码 代码如下:
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
复制代码 代码如下:
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
复制代码 代码如下:
function evalscript(s) {
if(s.indexOf('<script') == -1) return s;
var p = /<script[^\>]*?>([^\x00]*?)<\/script>/ig;
var arr = [];
while(arr = p.exec(s)) {
var p1 = /<script[^\>]*?src=\"([^\>]*?)\"[^\>]*?(reload=\"1\")?(?:charset=\"([\w\-]+?)\")?><\/script>/i;
var arr1 = [];
arr1 = p1.exec(arr[0]);
if(arr1) {
appendscript(arr1[1], '', arr1[2], arr1[3]);
} else {
p1 = /<script(.*?)>([^\x00]+?)<\/script>/i;
arr1 = p1.exec(arr[0]);
appendscript('', arr1[2], arr1[1].indexOf('reload=') != -1);
}
}
return s;
}
16、原生JavaScript清除脚本内容
复制代码 代码如下:
function stripscript(s) {
return s.replace(/<script.*?>.*?<\/script>/ig, '');
}
17、原生JavaScript动态加载脚本文件
复制代码 代码如下:
