项目中偶尔用到判断浏览器类型及相关版本问题,现记录相关代码:
function getBrowserVertion(userAgent) { var browserName, browserVersion, types, Info; if (userAgent.indexOf("MSIE") > -1) { types = userAgent.substring(userAgent.indexOf("MSIE")); Info = (types.split(";")[0]).split(" "); browserName = Info[0]; browserVersion = Info[1]; } else if (userAgent.indexOf("Firefox") > -1) { types = userAgent.substring(userAgent.indexOf("Firefox")); Info = (types.split(" ")[0]).split("/"); browserName = Info[0]; browserVersion = Info[1]; } else if (userAgent.indexOf("Chrome") > -1) { types = userAgent.substring(userAgent.indexOf("Chrome")); Info = (types.split(" ")[0]).split("/"); browserName = Info[0]; browserVersion = Info[1]; } else if (userAgent.indexOf("Opera") > -1) { types = userAgent.substring(userAgent.indexOf("Opera")); Info = (types.split(" ")[0]).split("/"); browserName = Info[0]; browserVersion = Info[1]; } else if (userAgent.indexOf("Safari") > -1) { types = userAgent.substring(userAgent.indexOf("Safari")); Info = (types.split(" ")[0]).split("/"); browserName = Info[0]; browserVersion = Info[1]; } else if (userAgent.indexOf("rv") > -1) { // for IE11 var result = userAgent.substring(userAgent.indexOf("rv"), userAgent.indexOf(")")); browserName = "MSIE"; browserVersion = result.split(":")[1]; } if (browserVersion.indexOf('.') != -1) { browserVersion = browserVersion.substring(0, browserVersion.indexOf('.')); } return browserName + "-" + browserVersion; }
测试:
getBrowserInfo(navigator.userAgent);
