I have a popup dialog box that I wish to display one of two slightly different views, dependant on whether I have data present or not.
Is there a way in which I can optionally pass in said data within the directives?
ie. I would like to use something like
<my-comp *ngIf="ifPopup" [data]="myData" [isNew]="isNew"></my-comp>
where the [data]
may not always be present, ie. It may either be undefined
or have actual data present.
I just want to avoid having to basically duplicate my component.
Update after confusion around my question Basically I am adding a new record to my DB (imagine adding a new customer etc). My component will either be used to edit a record or create a new record. If I am editing a record, myData will be filled with this record. If I am creating a new record, myData will be undefined..
why don't you just use
<my-comp *ngIf="ifPopup && myData" [data]="myData"></my-comp>
in this way, If the myData
is not present, your popup wont display
或者,您也可以使用<ng-container>
并将组件包装在其中,然后使用ngIf来存储数据!
