JavaScript 之 日常积累

1. <a>标签"加入收藏"，兼容IE，FireFox等

function bookmarksite() {
            if (window.sidebar) { 
                // Mozilla Firefox Bookmark
                window.sidebar.addPanel(document.title, window.location.href, '');
            }
            else if (window.external && ('AddFavorite' in window.external)) { 
                // IE Favorite
                window.external.AddFavorite(location.href, document.title);
            } else if (window.opera && window.print) { 
                // Opera Hotlist
                this.title = document.title;
                return true;
            } else { 
                // webkit - safari/chrome
                alert('Press ' + (navigator.userAgent.toLowerCase().indexOf('mac') != -1 ? 'Command/Cmd' : 'CTRL') + ' + D to bookmark this page.');
            }
        }
        //加入收藏
        function bookmarksite(title, url) {
            if (window.sidebar) // firefox
                window.sidebar.addPanel(title, url, "");
            else
                if (window.opera && window.print) { // opera
                    var elem = document.createElement('a');
                    elem.setAttribute('href', url);
                    elem.setAttribute('title', title);
                    elem.setAttribute('rel', 'sidebar');
                    elem.click();
                }
                else
                    if (document.all)// ie
                        window.external.AddFavorite(url, title);
            }

2、刷新页面避免重新发送

//用下面替换 document.location.reload()；
location.href = location.href; 

若为cs后台：在执行的方法尾部添加一条重载页面既可。

Response.Redirect(Request.Url.ToString());
