Go [JavaScript] using jquery plugin error: $.browser is undefined workaround

Just started to think that the plug-in error, on the official website to download a latest version of the Jcrop plug-in, the results of the original project page opened is normal, and the introduction of the project will be error, I found that may be related to the plugin version of jquery, View the official Demo catalogue under the Juqery version is V1.3.2,
And I'm using the jquery version of V1.11.1, looking at the official jquery update log, which is really the problem.
About $.browser
Browser is used to get basic information about the browser.

JQuery, starting with version 1.9, removed $.browser and $.browser.version and replaced it with $.support.
In the updated version 2.0, IE 6/7/8 will no longer be supported. Later, if the user needs to support IE 6/7/8, only jQuery 1.9 can be used.
Workaround
If you want to fully support IE and mix jQuery 1.9 and 2.0, the official solution is:
<!--[if Lt IE 9]> <script src= ' jquery-1.9.0.js ' ></script> <! [endif]-->
<!--[if GTE IE 9]> <script src= ' jquery-2.0.0.js ' ></script> <! [endif]-->
In the long run, this facilitates separate processing based on browser features in complex situations, rather than simply detecting browser types and versions.
But now many of the old procedures are not migrated directly to the browser support features, so on the Internet to find some solutions that can be directly replaced.
Determine browser type $.browser.mozilla =
/firefox/.test (Navigator.userAgent.toLowerCase ()); $.browser.webkit =
/webkit/.test (Navigator.userAgent.toLowerCase ()); $.browser.opera =
/opera/.test (Navigator.userAgent.toLowerCase ()); $.browser.msie =
/msie/.test (Navigator.userAgent.toLowerCase ());
The expression after the equal sign returns the True/false, which can be used directly to replace the original $.browser.msie.
