How to solve the jquery plug-in: TypeError:$.browser is undefined error report_jquery

First of all, let’s talk about $.browser
Browser is used to obtain basic information about the browser.
Starting from jQuery version 1.9, $.browser and $.browser.version were removed and replaced by $.support . In the newer 2.0 version, IE 6/7/8 will no longer be supported. In the future, if users need to support IE 6/7/8, they will only be able to use jQuery 1.9.
Solution: Just add the following js

(function(jQuery){  
 
if(jQuery.browser) return;  
 
jQuery.browser = {};  
jQuery.browser.mozilla = false;  
jQuery.browser.webkit = false;  
jQuery.browser.opera = false;  
jQuery.browser.msie = false;  
 
var nAgt = navigator.userAgent;  
jQuery.browser.name = navigator.appName;  
jQuery.browser.fullVersion = ''+parseFloat(navigator.appVersion);  
jQuery.browser.majorVersion = parseInt(navigator.appVersion,10);  
var nameOffset,verOffset,ix;  
 
// In Opera, the true version is after "Opera" or after "Version"  
if ((verOffset=nAgt.indexOf("Opera"))!=-1) {  
jQuery.browser.opera = true;  
jQuery.browser.name = "Opera";  
jQuery.browser.fullVersion = nAgt.substring(verOffset+6);  
if ((verOffset=nAgt.indexOf("Version"))!=-1)  
jQuery.browser.fullVersion = nAgt.substring(verOffset+8);  
}  
// In MSIE, the true version is after "MSIE" in userAgent  
else if ((verOffset=nAgt.indexOf("MSIE"))!=-1) {  
jQuery.browser.msie = true;  
jQuery.browser.name = "Microsoft Internet Explorer";  
jQuery.browser.fullVersion = nAgt.substring(verOffset+5);  
}  
// In Chrome, the true version is after "Chrome"  
else if ((verOffset=nAgt.indexOf("Chrome"))!=-1) {  
jQuery.browser.webkit = true;  
jQuery.browser.name = "Chrome";  
jQuery.browser.fullVersion = nAgt.substring(verOffset+7);  
}  
// In Safari, the true version is after "Safari" or after "Version"  
else if ((verOffset=nAgt.indexOf("Safari"))!=-1) {  
jQuery.browser.webkit = true;  
jQuery.browser.name = "Safari";  
jQuery.browser.fullVersion = nAgt.substring(verOffset+7);  
if ((verOffset=nAgt.indexOf("Version"))!=-1)  
jQuery.browser.fullVersion = nAgt.substring(verOffset+8);  
}  
// In Firefox, the true version is after "Firefox"  
else if ((verOffset=nAgt.indexOf("Firefox"))!=-1) {  
jQuery.browser.mozilla = true;  
jQuery.browser.name = "Firefox";  
jQuery.browser.fullVersion = nAgt.substring(verOffset+8);  
}  
// In most other browsers, "name/version" is at the end of userAgent  
else if ( (nameOffset=nAgt.lastIndexOf(' ')+1) <  
(verOffset=nAgt.lastIndexOf('/')) )  
{  
jQuery.browser.name = nAgt.substring(nameOffset,verOffset);  
jQuery.browser.fullVersion = nAgt.substring(verOffset+1);  
if (jQuery.browser.name.toLowerCase()==jQuery.browser.name.toUpperCase()) {  
jQuery.browser.name = navigator.appName;  
}  
}  
// trim the fullVersion string at semicolon/space if present  
if ((ix=jQuery.browser.fullVersion.indexOf(";"))!=-1)  
jQuery.browser.fullVersion=jQuery.browser.fullVersion.substring(0,ix);  
if ((ix=jQuery.browser.fullVersion.indexOf(" "))!=-1)  
jQuery.browser.fullVersion=jQuery.browser.fullVersion.substring(0,ix);  
 
jQuery.browser.majorVersion = parseInt(''+jQuery.browser.fullVersion,10);  
if (isNaN(jQuery.browser.majorVersion)) {  
jQuery.browser.fullVersion = ''+parseFloat(navigator.appVersion);  
jQuery.browser.majorVersion = parseInt(navigator.appVersion,10);  
}  
jQuery.browser.version = jQuery.browser.majorVersion;  
})(jQuery);  

Save the above js as browser.js and then import it in jsp.
