问题描述
我看得很远，但似乎找不到答案.我创建了一个指令，该指令可以正常工作，但是我想将其动态绑定到组件的主机.
I've looked far and wide but I can't seem to find an answer. I've created a directive, which works fine, but I want to bind it to the host of a component dynamically.
示例:
@Directive({ selector: 'myDirective' })
@Component({ selector: 'myComponent',
template: 'some content goes here...'
})
export class MyComponent {
/* bind myDirective to host */
}
//when using myComponent, it should be
<myComponent></myComponent>
//not
<myComponent myDirective></myComponent>
我基本上想消除以下需要:a)显式设置myDirective和b)用一个元素包装模板，以仅使用myDirective
I basically want to remove the need to either a) explicitly set myDirective and b) wrap the template with an element just to use myDirective
