如何在高级编译模式下使用Google Closure Compiler编译jQuery UI小部件（基于）？如何解决编译器引发的警告？

除了，您还需要一个jQuery UI外部文件。这是定义jQuery UI向编译器提供的符号和类型信息所必需的

遗憾的是，目前没有已知的jQuery UI外部文件。您可以选择创建足够的外部文件供您使用或使用简单的优化。

不幸的是，目前没有已知的jQuery UI外部文件。您可以选择创建足够的外部文件供您使用或使用简单的优化。

我想最好使用闭包库重写我的jQuery UI插件，并停止使用jQuery和jQuery UI。每个库都有其优点和缺点。选择装备ht库的工作和什么对你有意义。我个人不会改变库，因为它不适合与压缩器一起工作。对于基于jQuery的代码，我建议使用简单的闭包编译器优化。考虑到jQuery UI的流行和它的明显好处，我很惊讶这种需求这么长时间都没有得到满足他使用了闭包工具集。我想最好使用闭包库重写我的jQuery UI插件，停止使用jQuery和jQuery UI。每个库都有它的优点和缺点。为这项工作选择合适的库，并选择对您有意义的库。我个人不会更改库，因为库不能与压缩器一起使用。Fo在基于jQuery的代码中，我建议对闭包编译器使用简单的_优化。考虑到jQuery UI的流行和闭包工具集的明显优势，我很惊讶这种需求在这么长时间内一直没有得到满足。
