document.createElement多个参数 [英] document.createElement multiple arguments

问题描述

我正在阅读聚合物文档，我看到这样：

I was reading through the polymer documentation, and I saw this:

var el2 = document.createElement （'input'，'my-input'）; 来源

再次忘记聚合物，可以 document.createElement 目前有2个参数？是否与Polymer的类型扩展有关？

Forgetting about polymer for a second, can document.createElement currently take 2 arguments? Is it related to Polymer's type-extensions?

旁注：
网络风暴当我用2个参数调用它时，抱怨。

Side note: Webstorm was "complaining" when I called it with 2 arguments.

推荐答案

， document.createElement 只会占用一个参数（忽略第二个）。看来有一个规范可以让你传递一个 typeExtension ，你可以阅读关于 here 。 此规格仍在作品中，并且在任何浏览器上仍未以任何形式实施。

At the moment, document.createElement will only take one parameter (Ignoring the second). It does appear that there is a spec that will allow you to pass a typeExtension which you can read about here. This spec is still in the works, and is not implemented in any form on any browser as of yet.

快速编辑：它出现该chrome stable确实包含 typeExtension 参数，可以找到 here 。感谢@ScottMiles进行澄清。

Quick edit: It does appear that chrome stable does contain the typeExtension parameter, which can be found here. Thanks @ScottMiles for the clarification.
