Solve the problem that jquery1.9 does not support browser objects_jquery

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:

Copy the code Code 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 = '' 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);

This code is Specifically designed to solve the problem of browser objects not being supported.
