判断浏览器类型

js:

<script type="text/javascript">    //------------判断浏览器-----------    var Sys = {};    var ua = navigator.userAgent.toLowerCase();    var s;    (s = ua.match(/msie ([\d.]+)/)) ? Sys.ie = s[1] :        (s = ua.match(/firefox\/([\d.]+)/)) ? Sys.firefox = s[1] :        (s = ua.match(/chrome\/([\d.]+)/)) ? Sys.chrome = s[1] :        (s = ua.match(/opera.([\d.]+)/)) ? Sys.opera = s[1] :        (s = ua.match(/version\/([\d.]+).*safari/)) ? Sys.safari = s[1] : 0;    //------------判断浏览器-----------

if (Sys.ie) document.write(IE: + Sys.ie); if (Sys.firefox) document.write(Firefox: + Sys.firefox); if (Sys.chrome) document.write(Chrome: + Sys.chrome); if (Sys.opera) document.write(Opera: + Sys.opera); if (Sys.safari) document.write(Safari: + Sys.safari);</script>

c#:

    protected string BrowType = "ie";    protected void Page_Load(object sender, EventArgs e)    {        System.Web.HttpBrowserCapabilities browser = Request.Browser;        BrowType = browser.Browser.ToLower();    }

前台代码调用:

                <%if (!(BrowType == "ie" || BrowType == "safari"))                  {                %>                      <div style="height:40px;"></div>                <%                   }                 %>
