javascript - 防止 Jade 在 HTML 元素中添加赋值子句

Question

我想在 Angular 2 应用程序的输入标签中定义一个局部变量:

input(#sometext)
button((click)="addTechnology(sometext.value)") Add

我期望的输出是:

<input #sometext/>
<button (click)="addTechnology(sometext.value)">Add</button>

但是实际输出是(注意附加的 ="#sometext"):

<input #sometext="#sometext"/>
<button (click)="addTechnology(sometext.value)">Add</button>

这样，Angular 2 会抛出以下错误，很可能是因为 ="#sometext":

Cannot find directive with exportAs = '#sometext'

你知道有什么方法可以防止 Jade 使用额外的 ="#sometext" 完成属性吗？

最后就像在Jade 模板的开头使用doctype html 一样简单。我在主布局中有它，但似乎包含的文件也需要它。
