此方法使用 Sys.WebForms.PageRequestManager JavaScript类并可能是因为你有一个脚本管理上你的的.aspx 页。基本上后，每异步回发的的init（）函数将被调用。

This approach uses the Sys.WebForms.PageRequestManager JavaScript class and is possible because you have a Script Manager on your .aspx page. Basically after every async postback the init() function will be called.

注意的init（）功能也被称为在DOM准备好了。这可以让你做的一切的DOM需要重新完成后的内容异步回发过程中发生了变化。我使用不同的jQuery插件包括本之前已经使用了这种技术。

Notice the init() function is also called in DOM ready. This allows you to do everything to the DOM you need done again after content has changed during the async postback. I have used this technique before using various jQuery plugins including this one.
