It’s actually quite simple
if(navigator.userAgent.indexOf('UCBrowser') > -1) { alert("uc浏览器"); }else{ //不是uc浏览器执行的操作 }
If you want to test the characteristics of a certain browser, you can obtain it through the following methods
JS gets browser information
Browser code name: navigator.appCodeName
Browser name: navigator.appName
Browser version number: navigator.appVersion
Support for Java: navigator.javaEnabled()
MIME types (array): navigator.mimeTypes
System platform: navigator.platform
Plugins (array): navigator.plugins
User agent: navigator.userAgent
Relatively complete
<script type="text/javascript"> document.write('浏览器判別:'); var OsObject=navigator.userAgent; // 包含「Opera」文字列 if(OsObject.indexOf("Opera") != -1) { document.write('您的浏览器是Opera吧?'); } // 包含「MSIE」文字列 else if(OsObject.indexOf("MSIE") != -1) { document.write('您的浏览器是Internet Explorer吧?'); } // 包含「chrome」文字列 ,不过360浏览器也照抄chrome的UA else if(OsObject.indexOf("Chrome") != -1) { document.write('您的浏览器是chrome或360浏览器吧?'); } // 包含「UCBrowser」文字列 else if(OsObject.indexOf("UCBrowser") != -1) { document.write('您的浏览器是UCBrowser吧?'); } // 包含「BIDUBrowser」文字列 else if(OsObject.indexOf("BIDUBrowser") != -1) { document.write('您的浏览器是百度浏览器吧?'); } // 包含「Firefox」文字列 else if(OsObject.indexOf("Firefox") != -1) { document.write('您的浏览器是Firefox吧?'); } // 包含「Netscape」文字列 else if(OsObject.indexOf("Netscape") != -1) { document.write('您的浏览器是Netscape吧?'); } // 包含「Safari」文字列 else if(OsObject.indexOf("Safari") != -1) { document.write('您的浏览器是Safari 吧?'); } else{ document.write('无法识别的浏览器。'); } </script>
Many browsers are now based on the chrome browser, such as 360, Cheetah Browser, etc.
