这个jquery函数意味着什么? [英] What does this jquery function mean?
问题描述
我试图了解js库的工作原理,更具体地说是 http://toopay.github。 io / bootstrap-markdown / 。
I am trying to understand how a js library works, more specifically http://toopay.github.io/bootstrap-markdown/.
整个js文件包含在这个函数中:
The whole js file is wrapped in this function:
!function ($) {
}(window.jQuery);
这是做什么的,以及如何从库外再次调用它?
What does this do and how would I be able to call it again from outside the library?
推荐答案
它创建一个函数然后立即调用它。它之所以如此,所以它所做的所有变量都不是全局变量,因为它们将在函数内部。 !
只是为了避免在与其他脚本连接时造成问题并节省空间。
It creates a function then immediately calls it. The reason it does that is just so all the variables it makes won't be global, as they'll be inside the function instead. The !
is just to avoid causing problems when it's concatenated with other scripts and to save space.
您不能自己调用它,也不能自己调用。
You can't call it yourself, nor should you.
