Question

我想在Angular 2应用程序的输入标记中定义一个局部变量：

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

我期待的输出是：

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

然而实际输出是（注意额外的="#sometext"）：

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

这样，Angular 2引发了以下错误，很可能是由于="#sometext"：

Cannot find directive with exportAs = '#sometext'

您是否知道有任何方法可以阻止Jade使用附加="#sometext"完成属性？

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