And suddenly a few things stopped working: Quicksand plugin and part of my own jQuery code (that shows additional data under every slide of a slider). Can you help me figuring out what's wrong? Or maybe it's not worth moving to jQuery versions above 1.8.3? Check the Jsfiddle. HTML: <a href="#" class=

问题 I'm a bit confused how jquery searches through the DOM. Does it select from the root node, similar to XPath / selector, or from the current no matter where they are, similar to XPath // selector?

问题 Forgive me if there is an obvious answer to this question, but I haven't been able to find it. I am considering switching over to jQuery 2 and, although I'm not concerned about supporting older browsers, I would like to be able to tell users with unsupported browsers that they can't use the site. I see here (http://blog.jquery.com/2013/03/01/jquery-2-0-beta-2-released/) that you can use conditional comments to branch .js files on different versions of IE, but I believe jQuery 2.0 drops

问题 Using Visual Studio 2013, I migrated a hybrid Asp.Net Webforms/MVC 3 web application to Asp.Net Webforms/MVC 5.1. As part of the migration I upgraded Jquery from 1.9.1 to 2.1.1, using the NuGet package manager. When I run the application in the Visual Studio 2013 debugger in Chrome I have no problem. When I run the application in the Visual Studio 2013 debugger in IE 9 (compatibilty mode is not on) a master page with these two script tags loads first: <script src="/Scripts/jquery-2.1.1.js"
