Select2 Initialize select after appending data to existing select
提问by Umes Bastola
In my select2 select, i need to append li after document is ready, and after appending, how can i reinitialize select2. If I once close and again open the select, the appended data are selectable but not as soon as i append. How can i reinitialize it.
在我的 select2 选择中，我需要在文档准备好后附加 li，附加后，我如何重新初始化 select2。如果我曾经关闭并再次打开选择，附加的数据是可选择的，但不是在我附加后立即选择。我该如何重新初始化它。

You have to destroy the select2 on these elements and then reinitialize it.
您必须销毁这些元素上的 select2，然后重新初始化它。
$("select").select2("destroy").select2();

Thanks to @Mivaweb for answer above ^
感谢@Mivaweb 以上答案^
So if I use:
所以如果我使用：
$("select").select2("destroy").select2();
then I'm getting following issue as some guys in comments on answer above:
然后我遇到了以下问题，因为有些人对上面的答案发表评论：
The select2('destroy') method was called on an element that is not using Select2
But it does not mean that it is not working, it works, but need to update approach a bit.
但这并不意味着它不起作用，它起作用，但需要稍微更新方法。
Working solution for me:
我的工作解决方案：
STEP1: destroy existing select2 instances
STEP1：销毁现有的 select2 实例
STEP2: update options or select
STEP2：更新选项或选择
STEP3: and now init new select2 instances
STEP3：现在初始化新的 select2 实例
For example:
例如：
$(".select2me-filter").select2("destroy");
... Here do option updates you need
$(".select2me-filter").select2();
