(jQuery)在函数末尾意味着什么? [英] What (jQuery) means in the end of function?

问题描述

我有一个功能:

var waitingDialog = (function($){
.....
return{
}
})(jQuery);

您还可以解释$在函数中的含义吗?没有它，它会起作用吗?

Also could you explain what $ means in the function? Is it going to work without that?

推荐答案

在jQuery官方网站中有关于此的部分:

There is a section about that in official jQuery website : https://learn.jquery.com/plugins/basic-plugin-creation/#protecting-the-alias-and-adding-scope
