jquery - 需要对 jquery 插件样板进行哪些修改才能在 typescript 中编译？

Question

在jQuery 插件样板中，有一些很棒的 jQuery 插件开发起始代码，但是将这些代码复制并粘贴到打字稿中并进行编译会导致编译失败。

该错误来自undefined未（故意）调用的参数，因此问题是需要进行哪些修改才能使其编译。可以直接删除吗？

Answer 1

设为undefined可选：

// the semi-colon before function invocation is a safety net against concatenated
// scripts and/or other plugins which may not be closed properly.
; (function ($ : any, window, document, undefined?) {

// undefined is used here as the undefined global variable in ECMAScript 3 is
// mutable (ie. it can be changed by someone else). undefined isn't really being
// passed in so we can ensure the value of it is truly undefined. In ES5, undefined
// can no longer be modified.

这将允许模板编译，因为未定义未传递到函数中。
