Javascript：加载自执行匿名函数后执行代码

I have a script "selfexec.js" which does few things:

我有一个脚本“selfexec.js”,它做了一些事情:

!function(){ A = {init : init}}() 

I basically use this script as a plugin that can be loaded from other sites.

我基本上使用此脚本作为可以从其他站点加载的插件。

So, from Site B, I load this function and then want to call the method A.init but A is always coming out as undefined as its getting executed even before the anonymous function is loaded.

所以,从站点B,我加载这个函数,然后想要调用方法A.init但是A总是在未加载的情况下出现,因为它甚至在加载匿名函数之前就已经执行了。

I tried to attach it to the window but still no luck

我试着将它贴在窗户上,但仍然没有运气

Anyone has better approach of doing this? Any help would be appreciated

有人有更好的方法吗?任何帮助,将不胜感激

it seems like the issue is that you are trying to use A variable before it was initialized by 3rd party script. So the order is matter here: load 3rd party script before and start use it after. Also I personally like an approach with putting calls to the queue (similar approach is used even for google analitics). read about it more here

似乎问题是你在第三方脚本初始化之前尝试使用A变量。所以这里的顺序很重要:之前加载第三方脚本并在之后开始使用它。此外,我个人喜欢将呼叫调用到队列的方法(类似的方法甚至用于谷歌分析)。在这里阅读更多

so, you will need to define a way how your client should load code from your site and all methods will 100% be executed after 3rd party code was loaded and initialized.

因此,您需要定义客户端如何从您的站点加载代码的方式,并且在加载和初始化第三方代码后,所有方法都将100%执行。
