示例1: computed
/**
The `type` attribute of the input element.
@property type
@type String
@default "text"
@public
*/

get(): string {
return 'text';
},

}
return type;

}),
/**
The `size` of the text field in characters.
@property size
@type String
@default null
@public示例2: computed
/**
Accessed as a classname binding to apply the `LinkComponent`'s `disabledClass`
CSS `class` to the element when the link is disabled.
When `true` interactions with the element will not trigger route changes.
@property disabled
@private
*/
