The project has always used jquery1.9, which does not support browserobject. I searched on Baidu and found a solution. I would like to share it with you. Anyone has encountered this problem. Friends, don’t miss it

Recently, due to project needs, I have to use jquery’s cycle plug-in, but the project has always used jquery1.9, which does not support browser objects. I searched on Baidu and found a solution.

Just add the following code directly to the source code of the cycle plug-in:

The code is as follows:

(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 = &#39;&#39;+parse
Float
(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.sub
string
(verOffset+6); 
if ((verOffset=nAgt.indexOf("Version"))!=-1) 
jQuery.browser.fullVersion = nAgt.
substr
ing(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(&#39; &#39;)+1) < 
(verOffset=nAgt.lastIndexOf(&#39;/&#39;)) ) 
{ 
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(&#39;&#39;+jQuery.browser.fullVersion,10); 
if (isNaN(jQuery.browser.majorVersion)) { 
jQuery.browser.fullVersion = &#39;&#39;+parseFloat(navigator.appVersion); 
jQuery.browser.majorVersion = parseInt(navigator.appVersion,10); 
} 
jQuery.browser.version = jQuery.browser.majorVersion; 
})(jQuery);
