将一个页面设为首页(javascript代码)

<script type="text/javascript" language="javascript">

        function setHomePage(ele) {

            //使用对象特征检测法 检测当前浏览器是否是IE

            if (document.all) {

                ele.style.behavior = 'url(#default#homepage)';

                //设定当前页面的URL地址为主页地址

                ele.setHomePage(window.location.href);

            }

            //判断当前浏览器是否是FireFox

            else if (window.netscape) {

                try {

                    //检测当前浏览器是否允许设定主页或执行不安全脚本

                    netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

                }

                catch (e) {

                    //提示用户修改配置

                    alert("此操作被浏览器拒绝！\n请在浏览器地址栏输入“about:config”并回车\n然后将[signed.applets.codebase_principal_support]设置为'true'");

                }

                //获取Firefox特殊脚本服务

                var prefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components.interfaces.nsIPrefBranch);

                //设定主页

                prefs.setCharPref('browser.startup.homepage', window.location.href);

            }
