理解$与iife中的jQuery而不是$ [英] understanding $ vs. jQuery in iife instead of $
问题描述
我试图了解两者之间是否有任何区别
I am trying to understand if there is any difference between:
(function($){
...
})(jQuery);
vs.
(function($){
...
})($);
请注意，jQuery已用$代替.这个可以吗?是否因为无法使用而在任何地方都不使用?它可以工作，但也许是非标准的?如果错误或可以，有人可以解释一下吗? 谢谢
Note the jQuery was replaced with a $. Is this ok? Is it not used anywhere because it can't work? It works but maybe it is non-standard? Can someone please explain this if it is an error or if it is ok? Thanks
推荐答案
其他JavaScript框架也可以使用$作为快捷方式.为了保证$是函数中的jQuery，请传递jQuery而不是$.定义函数或代码区域"的这种类型是为了确保在混合框架时$确实是jQuery.
Other JavaScript frameworks may also use $ as a shortcut. To guarantee that $ is jQuery inside your function, pass jQuery and not $ at the end. This type of defining a function or "code area" is to take sure that $ really is jQuery when mixing frameworks.
