How to Solve Jquery 1.9 $.browser Error

When calling the jquery plug-in, a $.browser error occurred. It turned out that jQuery has removed attributes such as $.browser and $.browser.version since version 1.9.

Replaced by $.support.

Solution: 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);
