jQuery dependency on asp.net mvc site

I have an Asp.NET MVC 4.0 site that uses jQuery 1.11.1. I had an issue where some of the javascript on an end users browser (IE) was not working. For some reason, they had version 1.7.x of jQuery. I've been coding for a long time, but I'm relatively new in the web development area.

Why would the browser not download my copy of jQuery from the server? Is there a way to force the browser to get my version?

Thanks!

If the client is loading your site normally (calling an endpoint on your server) then there is no way they could load any version of jquery other than the one you have included in the script tag on your web page.

If you are doing something fancy like providing a widget that your user embeds in a page then indeed, depending on the order in which the scripts get loaded, the browser might wind up with a different version of jquery.

If you're doing the latter there are methods you can use to get a particular version of jquery for your code. See here for a start:

Include a specific version of JQuery and a plugin without conflicting with the page's JavaScript library?

Based on the comments below, you might also have other libraries in your application that also load jquery. The $ variable will get the last version of jquery to load. I would have thought that every browser would load them in the same order, but perhaps on older copies IE things happen differently (or perhaps there are paths through your app that load things in a different order).

If any of that's true then you'll have to use one of the techniques above. I'd also look into whether you can force kendo not to take over $.
