问题 Recently I've been playing around with different frameworks and libraries, looking for something that really suits my needs. You see, my job mainly involves creating asp.net mvc applications and for most of them using Razor and a little bit of jQuery is enough. But in certain cases and only for a few pages,which are rarely more than one or two per app, I really need something extra that helps me avoid getting entangled in a bunch of jQuery code. As I mentioned, I tried a couple of

How to avoid javascript namespace conflict?

由 喜你入骨 提交于 2019-12-06 12:53:52

For jQuery, the easiest thing is to use jQuery.noConflict() to get a new selector variable instead of $. var j$ = jQuery.noConflict(); j$('#test

However, I'm not sure why you would do this. Since you're dealing with JavaScript, it would be
