interface AttributeDecorator {

name | string |
any
Suppose we have an <input> element and want to know its type.
<input type="text">
The following example uses the decorator to inject the string literal text in a directive.
@Directive({selector: 'input'})
class InputAttrDirective {
constructor(@Attribute('type') type: string) {
// type would be 'text' in this example
}
} The following example uses the decorator in a component constructor.
@Component({selector: 'page', template: 'Title: {{title}}'})
class Page {
title: string;
constructor(@Attribute('title') title: string) {
this.title = title;
}
} | construct signature |
