javascript 检测浏览类型和版本

Posted 2021-12-02 zlero

废话不多说了，直接就上代码吧，因为IE11以后的版本和之前的不一样了，所以有些关键字还需要注意。这里面判断IE的时候需要多注意。
function getBrowserInfo()
{
   var ua = navigator.userAgent.toLocaleLowerCase();
   var browserType=null;
   if (ua.match(/msie/) != null || ua.match(/trident/) != null)
   {
      browserType = "IE"; 
      browserVersion = ua.match(/msie ([\d.]+)/) != null ? ua.match(/msie ([\d.]+)/)[1] : ua.match(/rv:([\d.]+)/)[1];
   }
   else if (ua.match(/firefox/) != null) { browserType = "火狐"; }
   else if (ua.match(/ubrowser/) != null) { browserType = "UC"; }
   else if (ua.match(/opera/) != null) { browserType = "欧朋"; }
   else if (ua.match(/bidubrowser/) != null) { browserType = "百度"; }
   else if (ua.match(/metasr/) != null) { browserType = "搜狗"; }
   else if (ua.match(/tencenttraveler/) != null || ua.match(/qqbrowse/) != null) { browserType = "QQ"; }
   else if (ua.match(/maxthon/) != null) { browserType = "遨游"; }
   else if (ua.match(/chrome/) != null) {
      var is360 = _mime("type", "application/vnd.chromium.remoting-viewer");
      function _mime(option, value)
      {
          var mimeTypes = navigator.mimeTypes; 
          for (var mt in mimeTypes)
          {
              if (mimeTypes[mt][option] == value) { return true; }
          }
          return false;
       }
       if(is360){ browserType = ‘360‘; }
       else{ $(‘html‘).css("zoom",".80"); }
    }
    else if (ua.match(/safari/) != null) { browserType = "Safari"; }
}
